The compounds of the present invention that include a basic moiety, such as an amino group, may form pharmaceutically acceptable salts with various amino acids, in addition to the acids mentioned above.

Those compounds of the present invention that are acidic in nature are capable of forming base salts with various pharmacologically acceptable cations. Examples of such salts include the alkali metal or alkaline earth metal salts and, particularly, the calcium, magnesium, sodium and potassium salts of the compounds of the present invention.

The compounds of the present invention have asymmetric centers and therefore exist in 20 different enantiomeric and diastereomeric forms. This invention relates to the use of all optical isomers and stereoisomers of the compounds of the present invention, and mixtures thereof, and to all pharmaceutical compositions and methods of treatment that may employ or contain them. In this regard, the invention includes both the E and Z configurations of the -OR3 group connected to the nitrogen where R1 and R2 are taken together as an oxkne moiety of the formula 25 sN-OR3. The compounds of formula ^ may also exist as tautomers. This invention relates to the use of aD such tautomers and mixtures thereof.

The subject invention also includes isotopicaliy-tabelled compounds, and the pharmaceuticaSy acceptable salts thereof, which are identical to those recited in Formula 1, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass 30 number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as 2H, 3H, 13C, 14C, 1SN, 180, 170, asS, 1#F, and *CI, respectively.

Tritiated, i.e., 3H, and carbon-14, i.e., 14C, isotopes are particularly preferred for their ease of preparation and 5 detectability. Further, substitution with heavier isotopes such as deuterium, i.e., 2H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labelled compounds of Formula 1 of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the 10 Schemes and/or in the Examples and Preparations below, by substituting a readily available isotopically labelled reagent for a non-isotopicaliy labelled reagent.

Useful herein are pharmaceutical compositions containing and methods of treating bacterial infections through administering prodrugs of compounds of the formula 1. Compounds of formula 1 having free amino, amido, hydroxy or carboxyfic groups can be 15 converted into prodrugs. Prodrugs include compounds wherein an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues is covalently joined through an amide or ester bond to a free amino, hydroxy or carboxylic acid group of compounds of formula 1^. The amino acid residues Include but are not limited to the 20 naturally occurring amino acids commonly designated by three letter symbols and also includes 4-20 hydroxyproiine, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-aianine, gamma-aminobutyric acid, citrulline homocysteine, homoserine, ornithine and methionine sutfone.

Derealization of hydroxy groups as (acyk>xy)methyi and (acyloxy)ethy! ethers wherein the acyl group may be an alkyl ester, optionally substituted with groups including but not limited to ether, amine and carboxylic acid functionalities, or where the acyl group is an amino acid ester as described above, are also encompassed. Prodrugs of this type are described in R.P. Robinson et al., J. Medicinal Chemistry (1996) 39,10.

Selective introduction of prodrug side chains can be carried out on the hydroxy groups of the hygromycin A core molecule. For instance, exhaustive silylation of the six hydroxy groups of hygromycin A can be carried out, for instance wj|h tert-butyl dimethytsHyl chloride. Subjection of the hexasiiyi derivative to the action of potassium carbonate in methanol at room temperature 5 selectively removes the phenolic sByl group, allowing further selective modification at that position. In another example, incomplete silylation of hygromycin A (see PC 10186, R. Linde, 2"-deoxy hygromycin A derivatives, U.S. provisional patent application no. 60/084,058, filed May 4, 1998) provides the pentasilyl derivative in which the C-2" hydroxy group is free. Selective acyiation, alkylation, etc. can be carried out on this derivative to provide prodrug attachment at 10 C-2".

Detailed Description of the Invention The preparation of the compounds of the present invention is illustrated in the following Scheme.

Scheme The compounds of the present invention are readily prepared. With reference to the Scheme illustrated above, the starting compound of formula 2 is hygromycin A which may be prepared according to procedures known to thos^skilled in the art, such as by fermentation of Streptomyces hygroscopicus NRRL 2388. The methyl ketone at 4" on the furanose sugar of 5 the hygromycin A molecule can exist in the S configuration (hygromycin A) or R configuration (epf-hygromycin) on the furanose sugar. When published protocols are used as a model for fermentation and recovery of hygromycin A (U.S. Patent 3,100.176; Antibiotic Chemotherapy (1953)3:1268-1278, 1279-1282), the hygromycin product is an approximately 3:1 mixture of hygromycin A (the 4"-{S) epimer), with the beta-oriented methyl ketone on the furanose sugar, 10 as drawn, and epAhygromycin. It is known in the literature (Journal of Antibiotics 33(7), 695-704, 1980) that pure hygromycin A will convert to ep/-hygromycin in alkaline solutions. By carefully controlling the pH below 6.9 during the fermentation, and the pH, temperature and solvent exposure during the purification process, the final recovered product may be improved to at least a 14:1 ratio of hygromycin A : epAhygromycin. Using this material, substantially 15 single isomers derived from the 4"-(S) hygromycin may be prepared for use as templates for further synthetic modification.

Hygromycin A enriched for the 4"-(S) epimer is produced by fermentation of Streptomyces hygroscopicus NRRL2388. or mutants thereof, in media with pH controlled at less than 6.9, preferably 6.2 to 6.7, throughout the process. The medium contains assimilable 20 sources of carbon, nitrogen and trace elements, as known to those skilled in the art The fermentation is run at a temperature of about 25-35°C, preferably about 29°C. The fermentation is monitored, for example by high pressure liquid chromatography. Incubation is continued until the yield of the compound reaches a maximum, generally for a period of about 3 to 10 days, preferably about 4 to 6 days.

The formation of epAhygromycin is minimized during the purification process by using an aqueous buffer (rather than unbuffered water) and controlling the pH of the active streams to near 6.0. Ep/-hygromycin formation is also minimized by minimizing the time the recovered material is subject to higher temperatures. Thus, where it is necessary to reduce solvent concentrations, it is preferred to dilute active streams with the aqueous buffer and avoid use 30 of rotary evaporation at elevated temperatures. Also, as means of avoiding higher temperatures, a resin column may be used to concentrate the active solution prior to the final purification step in order to reduce the volume of solution that must be boiled. The final purification step in the process is the concentration of the active cuts to soGds using vacuum and a bath temperature of about 35-50°C. The period in which the solution is subject to 35 elevated temperatures may be minimized by boding in stages.

The compounds of formula 1 wherein R1 and R2 are taken together to form an oxime of the formula =NOR3, wherein R3 is as defined above, may be prepared by treating hygromycin A (the compound of formula 2) wijh a hydroxylamine of the formula R^NHj, using the free base or salt of the hydroxylamine, preferably the free base of the 5 hydroxylamine. The reaction is carried out in an inert solvent, such as methanol, ethanol or pyridine, with addition of base, such as NajCOj or K2C03, if the salt, for instance the HCi salt, of the hydroxylamine is used, at a temperature ranging from about 0*C to 65°C, preferably from 0°C to 25"C. The hydroxylamine of formula R3ONH2 may be prepared using one or more procedures disclosed in Bioconjugate Chemistry (1990), 2, 96; Journal of Pharmaceutical 10 Science (1969) 58,138; and Chem. Pharm. Bull (1967) 15,345.

The compounds of formula 2 wherein R1 is H and R2 is -NR3R*, wherein R3 and R* are as defined above, can be synthesized by reductive amination at the C-5" ketone site of hygromycin A. Combination of R4NH2 and hygromycin A in an inert solvent and treatment with a reducing agent such as NaBH«, NaBH(OAc)j (Ac is acetyl), or NaCNBH3 provides the 15 product with R3 = H. To convert R3 to a group other than H, a second reductive amination can be carried out with an appropriate aldehyde or ketone of the formula RC(0)H or RC(0)R" (where R3 is RCHj- or RR'CH-, and R' and R are any of the moieties in the definition of R3 that may be attached through a methylene group such as an alkyl, arylalkyt, or heterocyclicalkyl group). An Eschwefler-Clark reaction may be used to introduce a methyl group as the R3 20 substituent. To provide an amide group, such as where R1 is H and R2 is -NR4C(0)R3, an amine of the formula -NHR4 may be introduced as described above and then an acyl moiety of the formula -CfOJR3 may be introduced by treating the intermediate with an activated form of the carboxylic acid, such as R3COCI or R3C(0)0C(0)R3, or by using an amide coupling agent such as (2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline (EEDQ), 1.1'-carbonyl-dMmidazole 25 (CDI), or a carbodiimide such as 1,3-dicydohexyicarbodiimide (DCC). During the above procedures, any of the hydroxyl groups of hygromycin A that are esterified can be liberated in a final deprotection step using I^COs in methanol.

Compounds of formula 1 where R1 is H and R* is -NR4C(0)R3, wherein R* is H and R3 is as defined above, may be prepared through use of the primary amine derived from 30 - reductive amination of hygromycin A with an ammonia equivalent, for instance through the use of ammonium acetate and sodium cyanoborohydride or sodium triacetoxyborohydride. Alternatively, this primary amine can be prepared via the corresponding azide: 1) the hydroxy groups of hygromydn A can be protected, for instance as their TBDMS (ferf-butyldimethyisilyl) derivatives, for instance through the action of TBDMSCI and an amine base such as imidazole 35 or pyridine; (2) the C-5" ketone of hygromydn A is then reduced, for instance with sodium borohydride in methanol, to give persilylated 5"-hydroxy hygromycin; 3) the resulting alcohol is transformed into the mesylate, for instance through the action of methanesulfonyl chloride and triethylamine; 4) the mesylate is displaced by azige, for example using sodium azide in N.N-dimethylformamide (DMF); and 5) the azide is reduced to the primary amine using for 5 instance triphenylphosphine followed by aqueous hydrolysis.

Reaction of the primary amine with an activated form of R^fOJOH, for instance R^OJCI or R3C(0)0C(0)R3. provides the corresponding amide. Alternatively, amide coupling reagents can be used with R*C(0)0H. such as 1-(3-dimethytaminopropyl)-3-ethyl-carbodiimide (EDC). diethyl phosphoryl cyanide (DEPC), DCC, CDI or EEDQ. Finally, any 10 protecting groups are removed using an add, such as acetic acid, hydrogen fluoride, hydrogen fluoride-pyridine complex, or fluoride ion, such as tetrabutytammonium fluoride (TBAF).

To incorporate an R* group other than H, the amide referred to above may be alkylated after protecting any free hydroxyl groups, for instance as silyl ethers. The alkylation 15 may be carried out with a base and an alkylating agent, such as sodium hydride and an appropriate bromide of Hie formula R*-Br. Deprotection of the hydroxyl groups is then carried out with an acid, such as acetic acid, hydrogen fluoride, hydrogen fluoride-pyridine complex, or fluoride ion, such as TBAF.

Alternatively, a reductive amination can be carried out on hygromycin A, or a 20 protected version thereof, with R4NH2, mediated by sodium triacetoxyborohydride or sodium cyanoborohydride. The resulting secondary amine can be acylated as described above, with an activated form of R3C(0)0H. or reacted with R*C(0)0H using an amide coupling reagent. Deprotection of the hydroxyl groups is then effected as descrtoed above.

Compounds of formula r where R1 is H and R2 is •0C(0)NR3R* may be prepared by 25 reacting persilylated 5"-hydroxy hygromycin A with isocyanate R*NCO in toluene at -temperatures from 40°C to 110°C, preferably 50 • 80°C. Addition of dknethyiaminopyridine and triethylamine to the reaction may be advantageous. The product of this reaction, which has R* equal to H, may be alkylated to give R* equal to C, - C10 alkyl through use of a base such as sodium hydride and an alkylating agent such as a bromide of the formula R*-Br. 30 Deprotection of the hydroxyl groups can then be carried out by use of an acid such as acetic acid, hydrogen fluoride, hydrogen fluoride-pyridine complex, or fluoride ion, such as TBAF.

Compounds of formula X where R1 is H and R2 is -OR3, wherein R3 is an alkyl group or a substituted alkyl group, may be prepared by alkylation of the corresponding alcohol of hygromydn A. In this process, the hydroxy groups of hygromydn A are appropriately 35 protected, for instance as their silyl ethers using an appropriate reagent such as triethylsSyi chloride (TESCI), trimethyisilyl chloride (TMSCI) or TBDMS and an amine base, such as imidazole or pyridine. The C-5" ketone moiety is then reduced using an appropriate reducing agent such as sodium borohydride in methanol^ The resulting alcohol can then be alkylated with R3-X, wherein X is a leaving group such as CI, Br or methanesulfonate, in the presence of 5 a base, such as sodium hydride or potassium terf-butoxide. The protecting groups are then removed with acid, such as acetic acid, hydrogen fluoride, hydrogen fluoride-pyridine complex, or a fluoride source, such as TBAF.

Compounds of formula 1 where R1 is H and R2 is -OR3, wherein R3 is an aromatic or heterocyclic moiety, may be prepared via a Mitsunobu reaction. The protected hygromycin 10 alcohol, prepared as described above, is subjected to a Mitsunobu reaction with R3OH, mediated by triphenylphosphine and diethyl azodicarboxylate as described in D.L. Hughes, Org. Reactions (1992) 42 335. The resulting ether is then deprotected as described above.

Alternatively, when R' is H and R2 is -OR3, wherein R3 is an aromatic or heterocyclic moiety, the protected hygromycin alcohol can be transformed into a leaving group, for 15 instance the bromide or mesylate derivative. The leaving group can then be displaced by R3OH using a base such as sodium hydride, potassium ferf-butoxide or potassium carbonate.

Compounds of formula whereri R1 and R2 are taken together to form =CR4C(0)R31 =CR4C(0)0R3, or =CR4C(0)NR3R4, wherein R3 and R4 are as defined above, may be prepared through the corresponding a.P-unsaturated ester intermediates derived from Wittig 20 or Horner-Emmons Wittig olefination of the C-5" ketone of hygromycin A. For instance, (carbethoxymethylene)triphenylphosphorane or (carbethoxyethylidene)triphenylphosphorane can be reacted with hygromycin A to provide the unsaturated ethyl ester. Hydrolysis of this ester, for instance with aqueous sodium hydroxide, provides the corresponding carboxylic acid (R1 and R2 taken together to form =CHC(0)0H). At this point, the hydroxyl groups of 25 hygromycin can be protected, for instance as their TES or TBDMS ethers as described above. To prepare the esters described above, this carboxylic acid can be esterified with R*OH, for instance through the action of DCC and DMAP. or CDI and a catalytic base such as sodium ethoxide.

Compounds of formula 2 wherein R1 and R2 are taken together to form 30 =CR4C(0)NR3R4 may be formed by treating the above carboxylic acid intermediate (R1 and R2 taken together to form =CHC(0)0H) with an amine of the formula R3NH2 with the use of an amide coupling agent such as DCC, CDI, EEDQ, DEPC, or EDC. On the protected derivative, R4 can be introduced via alkylation, for instance with a base such as sodium hydride or potassium terf-butoxide and an alkylating agent such as R*-X where is X is Br, CI or 35 methanesulfonate.

The compound of formula 1 (R' and R2 are taken together to form =CR4C(0)R3) can be prepared either by direct Wittig or Horner-Emmons reaction of hygromycin A or a protected form of hygromycin A with for example, the corresponding R3C(0)CHR4-PPh3 (Ph is phenyl) or R3C(0)CHR4-P=0(0Et)2 (Et is ethyl) reagent. Olefination can be carried out by procedures 5 described in J. Boutagy and R. Thomas, Chem. Rev. (1974) 74,87 and B.E. Maryanoff et al., Chem. Rev. (1989) 89 863. Alternatively, the protected, unsaturated carboxylic acid derivative of hygromycin A can be transformed into its Weinreb amide, for instance through treatment with CDI and N.O-dimethylhydroxyiamine. This amide can then be reacted with R3-M, where M is a metal ion such as Li or MgBr, to generate the ketone, according to the 10 procedure of S. Nahm and S.M. Weinreb, Tet. Lett. (1981) 22 39.

Compounds of formula 2 wherein R1 and R2 are taken together to form =CR*R3, wherein R3 and R4 are as defined above, may be prepared by a Wittig or Hormer-Emmons reaction of the ylid of R4-CH(PPh3)-R3 or R4-CH(P=0(0Et)J)-R3 with hygromycin A, or a protected derivative thereof, in which the hydroxyl groups have been modified as, for 15 example, their silyl ethers such as TES or TBDMS as described above. The protecting . groups can then be removed as described above.

Alternatively, the C-5" homologated ketone or aldehyde of hygromycin A can be utilized as an intermediate. These compounds can be accessed via Wittig or Homer-Emmons reaction with an oxygenated triphenylphosphonium salt or phosphorane such as Pt^P-20 C(R3)OMe (Me is methyl). The resulting enol ether can be hydrolyzed with mild add, such as acetic acid or dilute HCI, to provide the aldehyde or ketone. The aldehyde or ketone can then be reacted with an organometallic derivative R*M, where M is, for example. Li or MgBr, to provide the corresponding alcohol, which can be dehydrated under the action of methanesulfonyi chloride to provide the corresponding olefin. Deprotection as described 25 above then provides the compound of formula ^ wherein R1 and R2 are taken together to form =CR4R3.

The compound of formula 1_ wherein R1 and R2 are taken together to form =CR4R3 and R4 is aryl or heteroaryl and R3 does not equal hydrogen, may be prepared using a palladium-catalyzed process. Conversion of the protected ketone CH3-CH(COR3)-hygro to the enol 30 Inflate can be carried out by the method of PJ. Stang and W. Treptow, Synthesis (1980) 283. The enol triflate can then be coupled in a Suzuki or Stille-type palladium-catalyzed process with aryl or heteroaryl boronic acids R4B{OH)2 or aryl tin species, for example R4SnMe3 or R4SnBu3 to provide the unsaturated aryl derivatives. Suzuki coupling reactions can be carried out as described by N. Miyaura and A. Suzuki, Chem. Rev. (1995) 95 2457. Stille reactions are performed using conditions described in V. Farina et al.. Org. Reactions (1997) 50 1. Deprotection as described above then provides the final compound.

The compounds of the present invention i&ve asymmetric carbon atoms. Compounds having a mixture of isomers at one or more centers will exist as diastereomeric mixtures, which 5 can be separated into their individual diastereomers on the basis of their physical chemical differences by methods known to those skilled in the art, for example, by chromatography or fractional crystallization. Afl such isomers, including diastereomer mixtures, are considered as part of the invention.

The compounds of the present invention that are basic in nature are capable of forming 10 a wide variety of different salts with various inorganic and organic acids. Although such salts must be pharmaceutically acceptable for administration to animals, it is often desirable in practice to initially isolate the compound of the present invention from the reaction mixture as a pharmaceutically unacceptable salt and then simply convert the latter back to the free base compound by treatment with an alkaline reagent and subsequently convert the latter free base to 15 a pharmaceutically acceptable add addition salt. The acid addition salts of the basic compounds of this invention are readBy prepared by treating the basic compound with a substantially equivalent amount of the chosen mineral or organic add in an aqueous solvent medium or in a suitable organic solvent, such as methanol or ethanol. Upon careful evaporation of the solvent, the desired solid salt is readSy obtained. The desired acid salt can also be precipitated from a 20 solution of the free base in an organic solvent by adding to the solution an appropriate mineral or organic acid.

Those compounds of the present invention that are acidic in nature, are capable of forming base salts with various pharmacologically acceptable cations. Examples of such salts include the alkali metal or alkaline-earth metal salts and particularly, the sodium and potassium 25 salts. These salts are all prepared by conventional techniques. The chemical bases which are used as reagents to prepare the pharmaceutically acceptable base salts of this invention are those which form non-toxic base salts with the acidic compounds of the present invention. Such non-toxic base salts include those derived from such pharmacotogicaHy acceptable cations as sodium, potassium, calcium and magnesium, etc. These salts can easfly be prepared by 30 treating the corresponding acidic compounds with an aqueous solution containing the desired alkali metal alkoxide or metal hydroxide, and then evaporating the resulting solution to dryness, preferably under reduced pressure. Alternatively, they may also be prepared by mixing lower alkanolic solutions of the acidic compounds and the desired alkali metal alkoxide or metal hydroxide together, and then evaporating the resulting solution to dryness in the same manner as before. In either case, stoichiometric quantities of reagents are preferably employed in order to ensure completeness of reaction and maximum yields of the desired final product.

In the assay, a panel of bacterial strains is assembled to include a variety of target pathogenic species, including representatives of antibiotic resistant bacteria. Use of this panel enables the chemical structure/activity relationship to be determined with respect to potency and spectrum of activity. The assay is performed in microtiter trays and interpreted according to 15 Performance Standards for Antimicrobial Disk Susceptibility Tests - Sixth Edition; Approved Standard, published by The National Committee for Clinical Laboratory Standards (NCCLS) guidelines; the minimum inhibitory concentration (MIC) is used to compare strains.

According to one in vivo model, compounds are evaluated.for efficacy in mouse models of acute bacterial infection. An example of one such in vivo system is provided as foBows. Mice (CF1 mixed sex mice; 18-20 g) are allotted to cages upon the? arrival, and allowed to acclimate 1-2 days before being placed in a study. The acute infection is produced by intraperitoneal inoculation of bacteria (Staphylococcus aureus strain 01A1095) suspended 30 in 5% sterile hog gastric mucin. The inoculum is prepared by: growing the culture overnight at 37°C on blood agar, harvesting the resulting surface growth with sterile brain heart infusion broth, and adjusting this suspension to a turbidity that when diluted 1:10 into 5% sterile hog gastric mucin would produce 100% lethality.

Mice (10 per group) are treated subcutaneously, at 0.5 hour and 4 hours after 35 challenge. Appropriate non-treated (infected but not treated) and positive (vancomycin or minocydine, etc.) controls are induded in each study. Percent survival is recorded after a 4-day observation period; the PDy, (mg/kg/dose calculated to protect 50% of infected animals) is determined by the probit method. -fc The compounds of the present invention, and the pharmaceutically acceptable salts 5 thereof (hereinafter "the active compounds"), may be administered through oral, parenteral, topical, or rectal routes in the treatment of bacterial and protozoal infections. In general, these compounds are most desirably administered in dosages ranging from about 0.2 mg per kg body weight per day (mg/kg/day) to about 200 mg/kg/day in single or divided doses (i.e.. from 1 to 4 doses per day), although variations wi necessarily occur depending upon the species, weight 10 and condition of the subject being treated and the particular route of administration chosen. However, a dosage level that is in the range of about 3 mg/kg/day to about 60 mg/kg/day is most desirably employed. Variations may nevertheless occur depending upon the species of mammal, fish or bird being treated and its individual response to said medicament, as well as on the type of pharmaceutical formulation chosen and the time period and interval at which such 15 administration is carried out In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effects, provided that such larger doses are first divided into several small doses for administration throughout the day.

The active compounds may be administered alone or in combination with 20 pharmaceutically acceptable carriers or diluents by the routes previously indicated, and such administration may be carried out in single or multiple doses. More particularly, the active compounds may be administered in a wide variety of different dosage forms, i.e., they may be combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, troches, hard candies, powders, sprays, creams, salves, suppositories, jedies, gels, 25 pastes, lotions, ointments, aqueous suspensions, irqectable solutions, elixirs, syrups, and the tike. Such carriers include solid dSuents or faiers, sterile aqueous media and various non-toxic organic solvents, etc. Moreover, oral pharmaceutical compositions can be suitably sweetened and/or flavored.

Additionally, lubricating agents such as 35 magnesium stearate, sodium iauryl sulfate and talc are often very useful for tabletting purposes.

Solid compositions of a similar type may also be employed as fillers in gelatin capsules: preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene glycols. When aq&ous suspensions and/or elixirs are desired for oral adinistration, the active compound may be combined with various sweetening or 5 flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as wed, together with such diluents as water, ethanol, propylene glycol, glycerin and various like combinations thereof.

For parenteral administration, solutions of an active compound in either sesame or peanut oil or in aqueous ethanol or propylene glycol may be employed. Use of a cyciodextrin 10 derivative "such as p-cyclodextrin suffobutyl ether, sodium salt (see United States patent 5,134,127) may also be advantageous. The aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intraarticular, intramuscular and subcutaneous injection purposes. The preparation of all these solutions under sterile 15 conditions is readily accomplished by standard pharmaceutical techniques known to those skflled in the art.

Additionally, it is also possible to administer the active compounds of the present invention topically and this may be done by way of creams, jellies, gels, pastes, patches, ointments and the like, in accordance with standard pharmaceutical practice. 20 For administration to animals other than humans, such as cattle or domestic animals, the active compounds may be administered in the feed of the animals or orally as a drench composition.

The active compounds may also be administered in the form of liposome delivery systems, such as smaD unflamettar vesicles, large unilamellar vesicles and multilamellar 25 vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine or phosphatidylcholines.

The culture was grown for 3 days at 29°C with 200 rpcn agitation on a 2-inch-throw shaker. This grown culture was used to inoculate 8L of sterile hygromycin fermentation medium (Albaglos calcium carbonate 1 g/L, Sheffield Brand Products NZ Amine YTT 5 g/L. Hubinger's starch 20 g/L, Archer Daniels Midland Nutrisoy flour 10 g/L, Dow Chemical P2000 15 defoamer 1 ml/L, Baker CoC^-Sh^O 0.002 g/L. Colfax soybean oH 2 ml/L, cerelose 10 g/L, NaCI 5 g/L, pH to 7.0 before autoclave) in a 14 liter fermentor jar (New Brunswick Microferm, New Brunswick, New Jersey) equipped with two 4.75-inch Rushton impellers, spaced 3.75 inches from each other. The broth was incubated at 29*C with an aeration rate of 8 L/minute, and with stirring at 800 rpm. To minimize formation of epf-hygromycin, the pH was maintained 20 between 6.5 and 6.9 for 126 hours, then to 6.2 to 6.6 with H2SO4 (15%) for the rest of the run. The fermentation was harvested after 143 hours total incubation. At this time, the ratio was 31:1 hygromycin A to ^pAhygromycin.

Six liters of broth from the above fermentation was centrifuged at 8000 rpm for approximately 15 minutes. After centrifiigation, the pellet was discarded and the supernatant 25 (at pH 6.4, assayed by HPLC to contain approximately 4.12 gms of hygromycin A activity) was loaded on a column packed with 500 gms of an XAD-16 resin (Rohm and Haas (PhHadelphla, Pennsylvania). The resin had previously been equiibrated with two bed volumes of 25 mM di-sodium phosphate, pH 6.0 ("buffer")- After loading, the column was washed with 2 bed volumes of buffer and 2 bed volumes of 80/20 buffer/methanol and the activity eluted with 5 30 bed volumes of 50/50 buffer/methanol. The cuts were assayed by HPLC and the cuts containing the bulk of the activity (2.730 gms of hygromycin A) were combined.

A part of this XAD-16 eluate (approximately 800 mg of hygromydn A) was diluted to • 10% methanol by the addition of 1.8 liters of buffer and loaded on a 100 ml CG-161 column (TosoHaas (Montgomeryville, Pennsylvania)) which had been equilibrated with 4 bed volumes 35 of 90/10 buffer/methanol. The product was eluted with 6 bed volumes of 50/50 buffer/methanol. The cuts were assayed by HPLC and the active cuts were combined. The combined cut was evaporated to dryness and the solids assayed to be approximately 65% pure by weight. A small part of these solids were transferred for assay.

About 500 mg of the solids were mixed with 500 ml of water and 500 ml of ethyl 5 acetate and stirred for 20 minutes. The two layers were separated and part of the aqueous layer was dried to obtain solids which were assayed to be approximately 52% purity by weight. Both these solids (#34945-280-1 and 281-1) were assayed by NMR and TLC and found to contain hygromycin A activity, in addition, the NMR showed a hygromycin A/epA-hygromycin ratio of approximately 15:1. 10 Preparation 2 Five (5) mL of a frozen lot (stored at -80°C in 20% glycerol/80% inoculum medium) of the culture Streptomyces hygroscopicus NRRL 2388 was used to inoculate 1L of Hygromycin inoculum medium (CPC International Inc. cerelose 13 g/L. Hubinger's starch 7 g/L, Roquette com steep solids 3 g/L, NZ Amine YTT 7 g/L.

The culture was grown for 2 to 3 days at 29°C with 200 rpm agitation on a 2-inch-throw shaker. Two five-hundred gallon, stainless steel fermentors were loaded with 380-400 gallons of the hygromycin fermentation medium (Mineral Technologies Calcium Carbonate 1 g/L, Sheffield 20 Brand Products NZ Amine YTT 5 g/L, Hubinger's starch 20 g/L, Archer Daniels Midland Co.. Soyflour 10 g/L, Dow Chemical P2000 defoamer 1 ml/L, Baker CoClj.eHjQ 0.002 g/L, Colfax, Inc. soybean oil 2 gm/L, CPC International Inc. Cerelose 10 g/L, Cargill Inc. NaCI 5 g/L,). The medium was sterilized with 20 psig of steam for 60 minutes in the fermentors. After the medium was cooled using cooling cofls in the fermentors, the pH was adjusted to 6.5-6.7. The 25 fermentor conditions were set so that the airflow rate was 20 standard cubic feet per minute, the temperature was 28*C, the vent pressure was 5 psig, and the pH was maintained between 6.5 - 6.7 with 25% sodium hydroxide and 98% sulfuric acid. The agitation rates in the two fermentors were varied so as to maintain a dissolved oxygen level of greater than 20% of saturation level as measured in the broth immediately prior to inoculation. Upon setting the 30 fermentor control conditions, five Fembach inoculum flasks were combined in a sterile manner, into an 8 L aspirator bottle. This inoculum was then used for inoculation of a single, nominal, five-hundred gallon fermentor as described above. This procedure was repeated using 4 liters of inoculum so that one fermentor received four liters of inoculum and one fermenter received five liters of inoculum. Each fermentor ran for approximately 114 hours, at which time the fermentations were stopped. The broth pH was adjusted to 6.3 using 98% sulfuric acid and transferred from the fermentors for recovery.

The two fermentors referred to above (jjH= 6.3, having a ratio of hygromycin A to epA hygromycin of approximately 51:1) were filtered on a ceramic filtration system. The filtrate 5 (1450 gmsA. 506 gal) was loaded on a 70-gaiion XAD-16 resin column. This column had been equilibrated previously with 4 bed volumes of a solution of trisodium phosphate buffer at pH 6.0 ("buffer"). After loading, the column was washed with 2 bed volumes of buffer and 2 bed volumes of 80/20 buffer/methanol. The activity was subsequently eluted from the column with 10 cuts (approximately 50 gallons each) of a solution of 50/50 buffer/methanol. The 10 active cuts (approximately 1240 gmsA) were combined and diluted to a final concentration of 10% methanol by the addition of 1200 gallons of buffer. The use of dilution (rather than rotary evaporation) to reduce methanol concentration allowed the use of lower temperatures so as to minimize epAhygromycin amounts, which tend to increase at higher temperatures. Half of this solution was loaded on a 40 liter CG-161 column (previously equflibrated with 4 bed volumes 15 of a solution of 90/10 buffer/ methanol). After loading, the column was washed with 4 bed volumes of 80/20 buffer/methanol and eluted with 5.5 bed volumes of 50/50 buffer/ methanol. After regeneration and re-equilibration of the column, the second half of the activity was loaded on the column and eluted as described above. The combined cuts from both the runs (120 liters, approximately 1051 gmsA) were diluted to 10% methanol by the addition of buffer. 20 This was re-loaded on the regenerated and re-equilibrated CG-161 resin column. Once the activity was adsorbed on the column, it was eluted with 4 bed volumes of methanol. This step served to both reduce the salts as well as increase the concentration of the sample prior to the final evaporation. The combined cuts from the final CG-161 column were evaporated to dryness to obtain a total of approximately 1 kgA of hygromydn A activity. The ratio of 25 hygromydn A to epAhygromycin in the final solids was about 14.5:1.

Experimental Procedures For Examples In cases where final purification was effected using silica gel chromatography with an eluant system containing more than 10% methanol, the chromatographed product was taken up in 89:10:1 chloroform: methanol: concentrated ammonium hydroxide and filtered, or 30 dissolved in methanol and passed through a 0.45 nM filter. Removal of solvent in vacuo provided the final product. In the procedures below, t-BOC refers to "ferf-butoxycarbonyT.

"-Oxime Ether Preparations Preparation of hydroxylamine reagents for synthesis of oxime ethers. Examples 1-92. 1A-116A The majority of hydroxylamine reagents employed were either commercially available (generally as an acid salt), or prepared from the corresponding alcohol or halide via the methods outlined below: J 1) Preparation of phthalimide-protected benzylic or aliphatic hydroxylamines: 5 From the alcohol: A Mitsunobu reaction with diethyl azodicarboxyiate and triphenyiphosphine was used to couple N-hydroxyphthalimide and the alcohol starting material, according to the procedure of E. Grochowski and J. Jurczak, Synthesis (1976) 682.

From the bromide or chloride: 1 o Reaction of N-hydroxyphthalimide (1 equivalent) with the halide starting material (1.2 - 2 equivalents) was carried out in DMSO solution, using potassium carbonate (0.6 - 2 equivalents) as base. The reactions were carried out at room temperature, generally by stirring overnight. Pouring the reaction mixture into cold water provided a precipitate, which was filtered to give the phthalimide-protected hydroxylamine. In many cases, this material 15 was directly deprotected; silica gel chromatography can also be employed, using ethyl acetate-hexane mixtures, to purify the phthalimide-protected hydroxylamine. 2) Removal of the phthalimide protecting group to provide the benzylic or aliphatic hydroxylamine: Deprotection of the phthalimide-protected hydroxylamine was effected by reaction' 20 with hydrazine hydrate (1-2 equivalents) in ethanol solution, at temperatures ranging from room temperature to reflux, for periods ranging from 30 minutes to overnight. The reaction mixture was filtered, and the filtrate concentrated. This crude product can be taken to the next step as is. or can be further purified. Mixing the crude product with chloroform, removing solids by filtration and removal of solvent from the fltrate removes additional phthalhydrazide. 25 Alternatively, the crude product was dissolved in 1N hydrochloric acid, and washed with ether or ethyl acetate. The aqueous layer was basified with saturated potassium carbonate solution and extracted with ether or ethyl acetate. Drying of the final organic layers and removal of solvent provided the hydroxylamine product 3) Preparation of O-arylhydroxytamines: Substituted phenols were converted into the corresponding O-aryfhydroxylamines through the use of mesitytenesulfonylhydroxytamine, as described by Y. Endo, K. Shudo and T. Okamoto, Synthesis (1980) 461.
