Definitions
- This invention relates to a process for producing N-acyl-thienamycins.
- the present invention provides a process for the preparation of N-acyl-thienamycins which process comprises bringing thienamycin and acyl compounds into contact with certain penicillin amidohydrolases wherein N-acyl- thienamycin derivatives are produced.
- penicillin amidohydrolases capable of producing the N-acyl-thienamycins is meant the whole cells of the microorganism that produces an enzyme or mixture of enzymes extracted from these organisms, that causes the acyl compound to react with thienamycin to give the N-acylated thienamycins.
- Thienamycin is a new antibiotic (U.S. Patent No. 3,950,357).
- the teachings of U.S. Patent No. 3,950,357 are incorporated herein by reference.
- N-acyl thienamycins having the following structure: wherein R is an acyl group are produced by reacting the compound thienamycin, having the following structure: with an acyl compound, either the carboxylic acid, an amide thereof, a peptide thereof or a lower alkyl ester thereof, in the presence of penicillin amidohydrolases of the category designated E.C. 3.5.1.11 by the International Commission of Enzyme Nomenclature.
- the method of preparing the N-acyl-thienamycins is by reacting the appropriate acyl compound, either as tne carboxylic acid, an amide therof, a peptide therof or a lower alkyl ester thereof with thienamycin either in fermentation broth or an intermediate state of purity. Since the resulting derivatives can be more susceptible to isolation techniques employing organic solvents, they permit recovery of the thienamycin nucleus with higher efficiency from fermentation broths and concentrates. Once the derivatized thienamycin is recovered from the broth or solution, the acyl group can be removed in order to regenerate the thienamycin.
- the acyl radical R can be derived from a saturated or unsaturated, substituted or unsubstituted aliphatic with greater than 5 carbon atoms, aromatic or arylaliphatic carboxylic acid or carbothioic acid.
- One group of acyl radicals can be represented by the general formula: wherein X is O or S and R' represents a straight or branched chain alkyl group containing from 5-10 carbon atoms, aryl, aryloxy, typically containing 6-10 carbon atoms.
- Such above-listed groups can be unsubstituted or can be substituted by radicals such as OH, SH, SR" (R" is loweralkyl or aryl such as phenyl), alkyl or alkoxy groups having 1-6 carbon atoms, halo, such as Cl, Br, F and I, cyano, carboxy, nitro sulfamino, carbamoyl, sulfonyl, azido, amino, substituted amino such as alkylamino including quaternary ammonium wherein the alkyl group comprises 1-6 carbon atoms, haloalkyl such as trifluoromethyl, carboxyalkyl, carbamoylalkyl, N-substituted carbamoylalkyl, wherein the alkyl moiety of the foregoing four radicals comprises 1-6 carbon atoms, amidino, guanidino, N-substituted guanidino, guanidino lower alkyl and the like
- acyl groups that might be mentioned are those wherein R' is benzyl, aminobenzyl, phenoxymethylene, p-hydroxybenzyl, N-amyl, N-heptyl, 3- or 4-nitrobenzyl, phenethyl, B,B-diphenylethyl, methyldiphenylmethyl, triphenylmethyl, 2-methoxyphenyl, 2,6-dimethoxyphenyl, 2,4,6-trimethoxyphenyl, D-4-N-benzoylamino-4-carboxy-n-butyl, p-aminobenzyl, o-aminobenzyl, m-aminobenzyl, p-dimethylaminobenzyl, 2-ethoxy-l-napthyl, 4-guanidinomethylphenyl, 4- guanidinomethylbenzyl, 4-guanidinobenzyl, 4- guanidinophenyl, 2,6-dimethoxy-4
- the preferred compounds that can be utilized in this invention that fit the above acyl compound description are phenyl acetic acid, p-hydroxyphenyl acetic acid, p-aminophenyl acetic acid, 3-hexenoic acid and the N-glycyl and methyl esters of the above preferred carboxylic acids.
- Some examples of these preferred compounds are methylphenyl acetate, methyl p-hydroxyphenyl acetate, methyl p-aminophenyl acetate, methyl 3-hexenoate, N-glycylphenyl acetate, N-glycyl p-hydroxyphenyl acetate, N-glycyl p-aminophenyl acetate and N-glycyl 3-hexenoate. Also included within this preferred group are the amide, N-glycyl or methyl ester of phenylglycine. Some examples of these preferred compounds are N-glycyl phenylglycinate and methyl phenylglycinate.
- penicillin amidohydrolases used on an industrial scale to catalyze the hydrolytic removal of the side chain of penicillin to give the nucleus 6-aminopenicillanic acid (6-APA) can also be used to catalyze the reverse reaction.
- 6-APA plus acyl compound in the presence of penicillin amidohydrolase yield penicillin analogs.
- the synthetic reaction is generally promoted by the use of acyl compounds in the form of their lower alkyl (1-4 carbon atoms) esters present at high concentration and in excess of the 6-APA nucleus. That penicillin amidohydrolase is also capable of generating N-acylated thienamycins from thienamycin and appropriate acyl compounds is surprising.
- the process of this invention may be conducted by reacting the starting material of the general formula II along with the appropriate acyl compound as the carboxylic acid, an amide thereof, a peptide thereof or a lower alkyl ester thereof, in the presence of the enzyme from an extract of a cultured broth, the filtrate or fermentation product of the Escherichia coli culture or a powder of the enzyme in an aqueous solution.
- the enzyme may be immobilized by adsorption or chemical reaction to an insoluble supporting structure such as glass, cellulose or agarose, and used to generate N-acylated thienamycins either by contacting it (in the presence of appropriate acyl compounds as the carboxylic acid, an amide thereof, a peptide thereof or a lower alkyl ester thereof) in suspension or by percolation through a bed of immobilized enzyme preparation.
- an insoluble supporting structure such as glass, cellulose or agarose
- the enzyme is capable of producing N-acyl thienamycins from thienamycin present or produced in fermentation broths as well as from isolated thienamycin.
- acylation of thienamycin takes place in the presence of an enzyme of the microorganism of the genus Escherichia coli which is capable of producing the N-acylated thienamycins.
- the amidohydrolase enzyme For the production of the amidohydrolase enzyme by cultivation of the above-mentioned microorganism, there may be used various culture media commonly employed for the cultivation of a microorganism. More specifically, glucose, sucrose, glycerol, starch, oils used for cultivation and the like as a carbon source and peptone, buillion, corn steep liquor, yeast extract, meat extract, fish meal, defatted soybean, wheat embryo and the like as a nitrogen source may be employed. If required, other additives may be employed in combination with the above. It is an advantage but no a necessity to include phenylacetic acid or its salts or derivatives in fermentation media.
- Escherichia coli is usually shaken or agitated under aeration.
- Cultivation temperature may range from about 23-27°C.
- Cultivation period is usually 20-28 hours.
- the amidohydrolase contained in the cultured broth or its extract may be utilized in the present process without any further purification.
- the amidohydrolase enzyme may be precipitated with appropriate solvents, salted out or dialyzed or otherwise purified. It may be used free in solution or immobilized on an appropriate surface.
- a method utilized in the present invention is that of utilizing the whole cell amidohydrolase preparation. By this method, after cultivation, the culture is centrifuged to obtain the whole cells for subsequent reaction.
- reaction mixtures are incubated 18 hours at 23°C.
- the assay plates are prepared as follows: an overnight growth of the assay organism, Staphylococcus aureus ATCC 6538P, in nutrient broth plus 0.2% yeast extract is diluted with nutrient broth, plus 0.2% yeast extract to a suspension having 60% transmittance at a wavelength of 660 nm. This suspension is added to Difco nutrient agar supplemented with 2.0 g./l. Difco yeast extract at 47°C. to 48°C., to make a composition containing 33.2 mi. Of the suspension per liter of agar. Forty ml. of this suspension is poured into 22.5 cm. x 22.5 cm. petri plates, and these plates are chilled and held at 4°C. until used (5 day maximum).
- the TLC plate is removed and the assay plate incubated overnight at 37°C.
- the bioactive spots at R f 0.39-0.45 are due to thienamycin.
- the bioactive spot at R f 0.8 is due to N-phenylacetyl thienamycin.
