Abstract
A method of treatment for impotency is provided. The method involves the administration of nitric oxide by a nitric oxide-releasing agent capable of providing a penile erection-inducing amount of nitric oxide to the corpus cavernosum of the penis of an impotent male animal. Also provided is a nitric oxide delivery means for use in the method.
Description
Technical Field
The present invention relates to a method for treating impotence in men, and more particularly to the treatment of impotence using certain nitric oxide-releasing agents. The invention also relates to a nitric oxide delivery means comprising a nitric oxide delivery agent for use in the method.
Background
It is estimated that 1-2 million men in the united states alone suffer from moderate to severe forms of erectile dysfunction, and 1 million other men suffer from urinary tract dysfunction as a notable problem.
Erection and regression of the penis involve a complex process of direct nerve activation and interaction of contraction and relaxation factors from the endothelium. Changes in neurotransmitters and modulators of vascular activity have been described. Of which nitric oxide appears to play a major role in producing an erection.
Although it is believed that penile erection begins with the synthesis and release of NO from the non-adrenergic-non-cholinergic nerves of the corpora cavernosa, smooth muscle relaxation of the corpora cavernosa is one of the major factors of penile erection (Kimura et al, Nippon Hinyokika Gakkai Zasshi84 (9): 1660->1664 (1993); Rajfer et al, N.Engl, J.Med.326 (2): 90-94 (1992); Knispel et al, Urol, Res.20 (4): 253->257 (1992); Burnett et al, Science 257 (5068): 401: Mil403 (1992); and ls et al, biol. reprod.46(3 342-) (1992), during the determination of nitrite in men's sexual capacity, whether the peripheral and penile nitrate levels in the penile cavernosa and penile sponges increased the nitrate levels after the transient metabolic processes in blood (Mol. nitrate and nitrate levels in the penile cavernosa. the blood (transient level change) (Moire's) (3. RTM. for the test for nitrite increase in penile erection and the peripheral blood metabolism, the metabolic processes; for adult nitrite increase the metabolic processes; for penile erection process; for the metabolic processes, urology 42 (5): 551-553(1993)). However, physiological concentrations of oxygen in the cavernosal tissue of the penis are thought to regulate penile erection by regulating NO synthesis (Kim et al, J.Clin. invest.91 (2): 437-442 (1993)). Further assume that: the relaxation of the corpora cavernosa is initially due to the synthesis and release of nitric oxide from non-adrenergic, non-cholinergic nerves, which is amplified and maintained by the production of NO during the first phase of penile erection as a result of platelet entrapment in the corpora cavernosa (Alberti et al, Minerva. Urol. Nefrol.45 (2): 49-54 (1993)).
Currently available treatments for erectile dysfunction include direct needle injection of vasodilators into the penis; fixing with a compression ring by Vacuum Compression Device (VCD) to draw blood into penis; surgical implantation to strengthen the penis; oral agents such as gybine, only a small proportion of patients appear to show beneficial effects; psychological treatment has long-term benefits but with few data; vascular surgery, which is only available in a very small number of patients. All six of these treatments have significant drawbacks. In fact, these treatments are so limited that less than 10% of patients with erectile dysfunction adopt one of the six treatments described above. Furthermore, each of these treatments discontinues treatment in very high proportions, as it is completely silent on treatment itself. Thus, there remains a need for an effective method of treating impotence.
A method for studying penile dysfunction and penile erection, for example, due to diabetes and venous leakage, using nitric oxide. McGuffey discusses the potential use of nitric oxide for the treatment of impotence (am. pharm. NS 33 (7): 20 (1993)).
Pure nitrogen oxide, however, is a highly reactive gas with limited solubility in aqueous media (WHO Task Group on Environmental Health criterion for Oxides of Nitrogen, Oxides of Nitrogen. Environmental Health criterion 4(world Health Organization: Geneva, 1977)). Thus, nitric oxide is difficult to reliably introduce into most biological systems without premature decomposition.
A number of compounds have been developed which release nitric oxide in a pharmacologically useful manner. Some of these compounds include compounds that release nitric oxide by virtue of being metabolized, as well as compounds that automatically release nitric oxide in aqueous solution.
Compounds which are metabolized to release nitric oxide include the widely used nitrovasodilators glyceryl trinitrate, Sodium Nitroprusside (SNP) (Ignarro et al, J.Pharmacol. exp, Ther., 218.739-749 (1981); Ignarro, Annu.Rev Pharmacol Toxicol., 30, 535 560 (1990); Kruszyna et al, Toxicol., appl.Pharmacol., 91, 429-438 (1987); Wilcox et al, Chem.Res.Toxicol., 3, 71-76 (1990)), which are relatively stable except for the release of nitric oxide upon activation, although this feature may be an advantage in some applications, it may also be a noteworthy disadvantage, for example, the occurrence of trinitro resistance with depletion of the relevant enzyme/cofactor system (Phanerro et al, Androv., USA.32, 19814, 19811. RTV., 11. RTV. leading to prolonged cyanide production (Pharmacol. S.11, 19814, 19832, Topcol. 9, 19832), thus causing poisoning (Smith et al, "aporthi of Biological Reactive Intermediates" in Biological Reactive Intermediates IV. molecular and Cellular Effects and thermal Impact on human Health (Witmer et al, eds.), Advances in Experimental medicinal and Biological Volume 283(Plenum Press: New York, 1991), pp.365-369). S-nitroso-N-acetylpenicillamine (SNAP) has been reported to release nitric oxide in solution and effectively inhibit DNA synthesis (Garg et al, biochem. and Biophys. Res. Comm.171, 474-.
SNPs were administered to primates to study the physiology and pharmacology of erection (Hellstrom et al, J.Urol.151 (60: 1723-.
The NO donor linsidomine hydrochloride or the known 3-morpholino-sydnonimine or SIN-1 was administered to 30 patients with erectile dysfunction due to venous leakage (Wegner et al, Urology 42 (4): 409-411(1993), where 2/3 was treated with less efficacy than prostaglandin E1(PGE1). It was also found that SIN-1 was less potent than SNP in isolated corpus cavernosum of rabbit in relaxed state (Holmquist et al, J.Urol.150 (4): 1310-1315 (1993)). Stief et al performed a study of 63 patients with more promising results for SIN-1 (J.Urol.148 (5): 1437-. However, activation of SIN-1 with oxygen produces NO and superoxide ions, which combine to produce the strong oxidant ONOO-. The production of such toxic by-products may limit the use of the medetomine drug.
Drago describes a number of nitric oxide-nucleophile complexes (ACS adv. chem. ser.36, 143-.
These compounds contain the anion N2O2 -A group or a derivative thereof. Many of these compounds have proven to be particularly pharmacologically promising because, unlike SNPs and nitroglycerin, they release NO without first being activated. There are currently some other series of drugs, the S-iminothiol series, which are capable of releasing pure NO automatically and have the structure R-S-N ═ O (Stamler et al, proc. natl Acad sci. u s.a., 89, 444-; however, it is not limited to The reaction is kinetically complex and difficult to control (Morley et al, J.Cardiovasc.Pharmacol., 21, 670-(1990) Have been documented. In addition, S-nitrosothiolsThe oxidation state of nitrogen in the class of compounds is +3, not +2 in nitrogen oxide. While the R group in the R-S-N ═ O compounds provides a means to alter their chemical and hence pharmacological properties, the NONOate series are particularly multifaceted in this regard. NONOate having a reproducible half-life of 2 seconds to 20 hours has been prepared. Such compounds can be O-alkylated to provide spontaneous NO generators with a half-life of one week or more, or pro-drugs that do not release NO until the oxygen substituent is metabolically removed. The functional group of NONOate can coordinate to the metal center through two oxygen atoms; NONOate can also be attached to natural products, such as spermine (a component of human seminal fluid) and peptides; it can be combined with a solid polymer matrix to provide a source of NO. Compounds containing more than 1 nucleophile residue (e.g. polyamines, spermines) can bind to more than one NONOate group, thereby providing a single NONOate molecule with biphasic or multiphasic NO release rates. By providing such a wide variation in the rate of NO release, physical form and possible strategy for triggering NO release to specific parts of the body, NONOate constitutes a most advantageous family of compounds based on which attempts have been made to develop NO donor drugs.
Nitric oxide/nucleophile complexes (NONOates) that release nitric oxide in aqueous solutions are disclosed in U.S. patent nos. 4,954,526, 5,039,705, 5,155,137, 5,185,376, 5,208,233, 5,212,204, 5,250,550, 5,366,977, and 5,389,675, which are useful cardiovascular agents (see also Maragos et al, j.med.chem., 34, 3242-3247 (1991)).
Although the promise of nitric oxide/nucleophile complexes has been described in the literature, their pharmacological use has been limited by their propensity to distribute throughout the medium, and such a distribution has great advantages in many applications, in addition to its propensity to act selectively. However, nitric oxide/nucleophile complexes can be incorporated into polymers to overcome their limitations by allowing the concentrated, localized release of NO at a given site in a controlled and predictable effective dose. This gives great advantages to the treatment technique of penile dysfunction.
The present invention provides a method of treating impotence in male animals that overcomes the disadvantages of the current treatments described above by applying polymeric forms of NONOates as nitric oxide releasing agents, pharmaceutical compositions, and various delivery devices comprising the compositions and polymers. Correspondingly, the invention also provides a releasing device using the method. These and other objects and advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.

Detailed description of the invention
The present invention provides a method of treating impotence in male animals, including humans. The method involves administering a nitric oxide releasing agent to a male animal, particularly a human. The nitric oxide-releasing agent may be a substance comprising nitric oxide-releasing N2O2]A compound of a functional group or releasing with nitric oxide [ N]2O2]A polymer or a delivery device to which the functional group is attached, e.g. a transurethral agent, penile implant, skin plaster or condom containing such a compound or polymer. "bonded to a polymer" means bonded to [ N]2O2]Functional groups in combination, partial combination, with [ N]2O2]Functional group binding or [ N2O2]The functional groups are either physically or chemically contained in the polymer matrix. N is a radical of2O2 -The physical association or binding of the functional groups to the polymer may be achieved by co-precipitation of the polymer with the nitric oxide/nucleophile complex and N2O2 -The groups are covalently bonded to the polymer. N is a radical of2O2 -Chemical attachment of functional groups to polymers can be covalently attached to polymers through the nucleophile moiety of a nitric oxide/nucleophile adduct, such that the N attached to the nucleophile residue2O2 -The radical-forming polymer itselfI.e. attached in the polymer backbone or attached to a pendant group of the polymer backbone. Wherein nitric oxide-releasing N2O2 -The manner in which the functional groups are associated with, partially associated with, or otherwise associated with or contained within, i.e., "bound" to the polymer is immaterial to the present invention, and all manners of association and incorporation are contemplated herein.
The delivery means may be coated or manufactured with a nitric oxide delivery agent in a polymeric form to achieve a controlled, predetermined delivery of NO to the penis in an impotent, therapeutically effective dose. "nitric oxide delivery means" refers to many possible embodiments including nitric oxide delivery agents, such as transurethral agents, implants, drug pumps, catheters, self-adhesive devices, liposomes, microparticles, solutions, microspheres. Beads, pucks, or other pharmaceutical compositions as described more fully below. The delivery device may be biodegradable.
The nitric oxide-releasing agent provides sufficient NO to cause penile erection to the impotent male. Determination of a sufficient amount to induce penile erection as described below with respect to dosage, it is readily determined whether a particular animal has impotence. Whether a particular animal is at risk for impotence can be assessed by those skilled in the art by considering known risk factors. Such as diabetes or venous leakage, may be a risk factor for impotence in men.
The present invention also provides various different nitric oxide delivery devices for use in the methods of the present invention, as described more fully below.
Nitric oxide releasing [ N]2O2]The functional group being X- [ N (O) NO]Or [ N (O) NO]-X, wherein X is bound to- [ N (O) NO]Or [ N (O) NO]-organic or inorganic part of the functional group. Containing [ N]2O2]The functional group compounds can be incorporated as part of the polymer. [ N]2O2]The group can be covalently incorporated into the polymer through the X moiety. Introduction of N into polymers2O2 -The functional group enables NO to be released locally to the penis. "local delivery" refers to entry into or close proximity to the corpus cavernosum of the penis. Local release enhanced nitric oxide release [ N]2O2]Selectivity of functional group action. If attached to polymers [ N]2O2]The functional group is localized and its effect of releasing NO will be concentrated on the tissue with which it is in contact. If the polymer is soluble, selectivity of action is still present, for example, by attaching or derivatizing an antibody specific for the target tissue. Similarly, [ N]2O2]Functional groups attached to small peptides mimic recognition sequences of ligands for important receptors, thereby providing localized, focused NO release, which would otherwise attach to nucleic acidsThe target sequence is located on the oligonucleotide which specifically interacts.
In addition, [ N]is introduced into the polymer2O2]The functional group reduces the tendency of the nitric oxide/nucleophile adduct to release NO relatively quickly. This is by [ N]2O2]The functional groups prolong the release of NO, allowing effective delivery of the drug to achieve penile erection, with a concomitant reduction in the frequency of drug delivery.
While not being bound by any particular theory, it is believed that the longevity of nitric oxide release in the composition of the polymer-nitric oxide/nucleophile adjunct of the present invention is due to the physical structure and electrostatic effects of the composition. Therefore, we believe that if the polymer is a water-insoluble solid, N is present near the surface of the particles2O2 -Based on the ability to release rapidly, while those of N buried deeply2O2 -The radicals are spatially shielded and require more time and/or energy to get the nitrogen oxides into the medium in their own right. Unexpected, has been found to be N2O2 -The increased proximity of the functional group to the positive charge also results in an increase in the half-life of nitric oxide production. This half-life delay mechanism can be simply attributed to electrostatic repulsion, i.e., at N2O2 -Radicals adjacent to increase H+A repulsive positive charge, suppressing the positive charge H+Ion pair N2O2 -Attack of functional group to reduce its H+-rate of catalytic decomposition. For example, by attaching amino groups to a polymeric support, nitric oxide-releasing N can be formed when reacting with nitric oxide2O2 -Functional groups, which when non-consumed with nitric oxide, produce partially converted structures, which, after exposure to water, contain a large amount of surrounding N2O2 -Positively charged amino centres of radicals, electrostatic inhibition of which causes the liberation of nitrogen oxides from nitrogen oxides by N2O2 -Lost H in functional groups+Ion pathway.
Nitric oxide releasing [ N]2O2]The functional groups are typically bound to a polymer and when contacted with an aqueous environmentAre capable of releasing NO spontaneously in an aqueous environment, i.e. they do not require activation by redox reactions or electrostatic transfer, as is required for example for glyceryl trinitrate and SNPs. Some nitric oxide/nucleophile complexes used in the context of the present invention do require activation by specific methods, but such activation is only when it is desired to release nitric oxide as X-X- [ N (O) NO]-Groups are necessary when the penis or corpus cavernosum is free in the vicinity. As an example, the anion [ N (O) NO]-Covalent attachment of the functional group to the protecting group provides a means of delaying the release of NO until the molecule reaches the penis, where the cell/tissue can metabolically remove the protecting group. The polymer bound nitric oxide releasing composition of the present invention is capable of releasing NO in an aqueous solution, such a polymer preferably releasing NO under physiological conditions.
Nitric oxide releasing [ N]2O2]The functional group is preferably a nitric oxide/nucleophile adduct, i.e. a complex of NO and a nucleophile, most preferably X- [ N (O) NO containing an anionic moiety]Wherein X is any suitable nucleophile residue. The nucleophile residue is preferably a primary amine (e.g. X ═ CH3)2CHNH, e.g. in (CH)3)2CHNH[N(O)NO]Na), a secondary amine (e.g., X ═ CH (CH)3CH2)2N, e.g. in (CH)3CH2)2N[N(O)NO]Na), a polyamine (e.g. X ═ spermine, as in zwitterion H)2N(CH2)3-NH2 +(CH2)4N[N(O)NO]-(CH2)3NH2In (e) X ═ ethylamino, e.g. in the zwitterion CH3CH2N[N(O)NO]-CH2CH2NH3 +In or X ═3- (n-propylamino) propylamines, e.g. in zwitterionic CH3CH2CH2N-[N(O)NO]-CH2CH2CH2NH3 +In (ii) or an oxide (i.e., X ═ O)-Such as in NaO [ N (O) NO]In Na) or derivatives thereof.

A wide range of polymers can be used in the context of the present invention, except that the polymer selected must be biologically acceptable. Polymers suitable for the present invention are exemplified by polyolefins such as polystyrene, polypropylene, polyethylene, polytetrafluoroethylene, polyvinylidene fluoride, polyvinylidene chloride, polyethyleneimine, and derivatives thereof, polyethers such as polyethylene glycol, polyesters such as poly (lactide/glycolide); polyamides such as nylon, polyurethanes, Starburst peptides biopolymers, such as peptides or proteins (e.g., antibodies), nucleic acids (e.g., oligonucleotides), and the like.
The physical and structural characteristics of the polymers suitable for use in the present invention are not critical, but depend on the route of administration and the frequency of administration. The polymer can be biodegradable.
The nitric oxide releasing agent may be administered in a variety of forms of delivery devices, any of which should suitably preserve the integrity of the NO before its release, and control the release of NO so that it is delivered at a release rate, amount and location effective to treat impotence. For example, delivery devices for topical or local delivery include, but are not limited to, penile implants, drug pumps, drug delivery catheters (compression devices, iontophoresis devices, transurethral devices), self-adhesive devices, liposomes, microparticles, microspheres, beads, condoms, dermal patches, discs or other devices. Advantages of local administration or local release include the ability to achieve effective concentrations of NO at the target site faster, and with smaller doses, less toxic side effects than systemic administration or systemic release. Systemic delivery devices for topical delivery include, but are not limited to, solutions, suspensions, emulsions, capsules, sachets, tablets, dermal (topical) plasters, lozenges, aerosols, liposomes, microparticles, microspheres, beads, prodrugs, tissue-specific antibodies, small peptides mimicking ligand recognition sequences, as described above, and sequence-specific oligonucleotides. The polymer itself may be structurally sufficient to be used in the form of a delivery device. Alternatively, the polymer can be bound to or coated onto other substrates, or the like, or can be microencapsulated or the like.
Nitric oxide releasing [ N]comprising the above compounds2O2]Functional groups, which can be bound to the polymeric support in a number of different ways. For example, the compounds can be bound to the polymer by coprecipitation of such compounds with the polymer. Coprecipitation involves, for example, dissolving both the polymer and the nitric oxide/nucleophile compound, followed by removal of the solvent by evaporation. Containing [ N]2O2]The monomers of the radicals are also soluble in the molten polymer, which solidifies when the temperature is lowered, in which medium there is a considerable homogeneity of [ N]2O2]Distribution of functional groups.

One skilled in the art will appreciate that suitable methods of administering the nitric oxide-releasing agents of the present invention to a male animal, including a man, although more than one route can be used to administer a particular compound or polymer, one particular route can provide more immediate and more effective results than another route. The choice of pharmaceutically acceptable carrier will depend, in part, on the particular pharmaceutical composition and the particular method of administration. Thus, suitable formulations for use in the pharmaceutical compositions of the present invention vary widely.
Formulations suitable for oral administration include (a) liquid solutions, such as an effective amount of a polymer-bound composition dissolved in a diluent, such as water or saline, (b) capsules, sachets or tablets containing a predetermined amount of the active ingredient, such as a solid or granules, (c) suspensions in a suitable liquid, and (d) suitable emulsifying agents. Tablets contain one or more of lactose, mannitol, cereal starch, potato starch, microcrystalline cellulose, gum arabic, gelatin, colloidal silicon dioxide, croscarmellose sodium, talc, magnesium stearate, stearic acid, and other adjuvants, colorants, diluents, buffering agents, wetting agents, preservatives. Flavoring agents and pharmaceutically suitable carriers. Lozenges comprise the active ingredient, usually flavoured with sucrose, acacia or tragacanth, the active ingredient of the lozenge being contained in an inert base such as gelatin, glycerol or sucrose,gum and acacia milk and similar carriers well known to those skilled in the art.
Suitable dosage forms for parenteral administration include aqueous and nonaqueous, isotonic sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which are capable of being rendered isotonic with the blood of the recipient, aqueous and nonaqueous sterile suspensions containing suspending agents, solubilizers, thickening agents, stabilizers and preservatives. The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampoules and vials, or may be stored in a freeze-dried (lyophilized form) condition requiring only immediate injection upon dilution with a sterile carrier, for example water, prior to use. Solutions or suspensions for immediate injection may be prepared using sterile powders, sterile granules and sterile tablets.
Transurethral administration is preferred, although not essential. The term "transurethral" is used to refer to the release of drugs into the urethra such that the drugs contact and pass through the urethral wall. As set forth in co-pending U.S. patent application Ser. No.07/514,397 (published in International WO91/16021), entitled "treatment of penile dysfunction," the disclosure of which is incorporated herein by reference, transurethral administration can be performed in different ways, e.g., medication can be introduced into the urethra via a flexible tube, squeeze bottle, pump, or aerosol spray. The drug may be contained in a coated tablet, pill or suppository to be absorbed, dissolved or infiltrated in the urinary tract. In certain embodiments, the drug is coated on the outer surface of the penile inserter. A preferred drug delivery device for transurethral administration is shown in FIG. 1.
In fig. 1, 10 generally indicates a transurethral drug delivery device comprising an inserter 11 having an easily graspable quadrant 12, the quadrant 12 having opposite symmetrical concave surfaces 13 and 14 adapted to be grasped by 2 fingers, the drug being contained in a long handle 15 of a size comparable to the urethra. The inserter 11 can be moved by inserting the shaft 15 into the urethra in order to push the drug into the urethra by slidably inserting the shaft 15 through the top end of the piston 16 into the radial hole in the middle of the shaft 15, and pressing the end of the piston 16 against the sector 12. Before use and during storage, the device is covered by an elongate cap 17 which fits snugly against a flange 18 adjacent the elongate shaft 15, the cap 17 being fitted with a series of parallel keels 19 to facilitate grasping and removal of the cap from the inserter.
While the configuration shown in fig. 1 is the preferred configuration, other inserter/container configurations can be employed, and the principle of transurethral administration used in the present invention is to introduce a predetermined amount of drug from the inserter into the urethra at a predetermined depth. Another example of such a device is also described and illustrated in WO91/16021 (incorporated herein by reference). The device can be manufactured both under sterile conditions, thus obviating the need for post-manufacture sterilisation, and under non-sterile conditions, and then further sterilised by suitable techniques, such as irradiation. The device may also be manufactured by typical plastic forming and coating processes that are well known to those skilled in the art, including molding, thermoforming, dip coating, and the like.
The drug may also be administered topically transdermally or by other effective means. As is well known to those skilled in the art, transdermal administration involves the transdermal release of an agent into the systemic circulation of a patient. See transdermal drug delivery: development Issues and Research Initiatives, Hadgraft and Guy (eds.), Marcel Dekker, Inc. (1989); controlling the release of the drug: foundation and applications, Robinson and Lee (eds.), Marcel Dekker, inc., (1987); and transdermal delivery of drugs, Vols.1-3, Kydonieus and Berner (eds.), CRC Press (1987).
Different types of transdermal patches used in the present method are described herein. For example, simple adhesive plasters are made from a backing material and an acrylate adhesive. The adhesive layer is formulated such that the application drug, carrier or enhancer is contained therein. Alternatively, a hydrogel matrix patch may be used in which a drug, water and typically a hydrophilic polymer are used to form a hydrogel matrix, which is then added between the backing and adhesive layers of the transdermal patch. It will be appreciated by those skilled in the art that other types of construction of the plaster can be used, including liquid reservoir plasters, foam matrix plasters and the like. See U.S. patent nos.3,598,122, 4,649,075 and 5,120,544, the disclosures of which are incorporated herein by reference.
Other components can also be incorporated into such transdermal patches. For example, the compositions and/or transdermal patches may be formulated with one or more preservatives or bacteriostats, such as methyl paraben, propyl paraben, chlorocresol, benzalkonium chloride, and the like.
The present invention is based on the insight that the dosage administered to an animal, in particular a human, should be sufficient to effect a penile erection in a man within a reasonable time. This dosage will be determined by the strength of the particular nitric oxide-releasing agent being used, the type of delivery device being used, the route of administration, the condition and weight of the animal being treated, the timing of administration, and the like. And the frequency of administration, the length of administration, etc. are determined by intercourse. The size of the dose will also depend on the condition of the animal being tested, the animal's personality, and the extent of adverse side effects associated with the particular composition or delivery device. A suitable dosage, for example, about 0.002mg to about 100mg of nitric oxide, may be administered acutely or chronically, preferably acutely.
The following examples further illustrate the invention but are not to be construed as limiting the scope thereof.
Example 1
This example illustrates the preparation of polymer-bound nitric oxide/nucleophile complexes by a process of co-precipitation of the monomeric form thereof with the polymer.
1g of polymer [ poly (lactide/glycolide, 50: 50) from Medisorb was dissolved in 2ml of tetrahydrofuran, and 300mg of DETA/NO, [ H]were added to the solution2N(CH2)]N-N2O2H, zwitterion, mixture was stirred under argon and solvent was slowly removed until the mixture was thick to no stirring. The mixture was then placed in a vacuum oven (about 1mm) and held at 30 ℃ for 5 hours to remove residual solvent, and finally the mixture was pressed on a clich at a pressure of 2 ten thousand pounds for 5 minutes at 140 ° F to produce a 1 x 144 mil thick film. The recovery of nitric oxide after casein treatment of the polymer was 8nmol NO per mg of solid using the chemiluminescence procedure described by Maragos et al (J.Med.chem.34, 3242-3247 (1991)).

Example 4
This example illustrates the preparation of a polyethylene glycol based NO-releasing polymer using two different preparation methods. In both methods the polymer-bound nitric oxide/nucleophile complex is generated by co-precipitation of the nitric oxide/nucleophile compound in monomeric form with the polymer.
In the first method, 20mg of the sodium salt of 1, 1-diethyl-2-hydroxy-2-nitrosohydrazine (DEA/NO) and 2.5g of polyethylene glycol-1450 (Union Carbide) were dissolved in 25ml of methanol. The homogeneous solution was placed in a rotary evaporator at 40 ℃ to remove the solvent under vacuum to give a homogeneous solid solution. The samples were stored in clean vials at ambient temperature and ambient pressure of typical laboratory light. The stability of the product is more than 7 days. The absorption of the polymer was monitored by electron spectroscopy at a peak of 250 nm. No change in absorption was observed during this period.
In the second method, 2.5g of polyethylene glycol-1450 was heated to 46 ℃ until completely melted. To this liquid polyethylene glycol was added 36mg (0.232nmol) of DEA/NO while the vessel was placed in a vortex mixer. A homogeneous solution is obtained which solidifies gradually upon cooling to ambient temperature. The stability of the solution was determined as described above. No change in absorbance of the 250nm chromophore was seen during 7 weeks storage.
Example 5
This example illustrates the preparation of a complex consisting of a polyamine/nitric oxide complex, N- [4- [1- (3-aminopropyl) -2-hydroxy-2-nitrosohydrazino) butyl]-1, 3-propanediamine zwitterionic form (SPER/NO) and polyethylene glycol (PEG) by a process of co-precipitation of polymer and nitric oxide/nucleophile.
A1.2% (w/w) KOH solution of polyethylene glycol-1450 was prepared in an aqueous medium and evaporated to dryness under vacuum (PEG-KOH). To 1.144g of melted PEG-KOH was added 11.65mg (0.042mmol of SPER/NO), and the resulting mixture was mixed to a uniform concentration.
Example 6
This example describes the induction of erection in anesthetized cats with DEA/NO and SPER/NO. Anesthetized cats are a good model of the erectile response in humans. Unlike other models that have been used, the erectile responses of cats and humans show similarities in both structure and pharmacology. For example, cats are the only animal model in which a response of both the NO donor and the prostaglandin can be observed, except for certain primates.
Adult male anesthetized cats were injected with different vasoactive agents alone or in combination in the corporeal cavernosum of the penis to determine their efficacy on changes in body pressure and length of the penis (Wang et al, J. Uroll 151: 234-. Each time a test compound is given, followed by a control compound in order to compare the reaction of the test compound and the control compound.
DEA/NO and SPER/NO were dissolved in 10mM NaOH and papaverine (1.65mg), phenoxazoline (25. mu.g), prostaglandin E1(PGE1) (0.5. mu.g) 200. mu.l of the carrier, and 10mM NaOH solution as a control. The compounds were treated identically, and were administered in dose ranges of 3, 10 and 30. mu.g/200. mu.l.
The test results are shown in fig. 2 and 3. FIG. 2 is a graph of body pressure (mmHg) versus dose (μ g/200 μ l) depicting the adverse effects of body pressure on intracavernosal NONOates injection in anesthetized cats. Results are presented as mean ± SEM of intracavernosal pressure response per animal.The control contains papaverine 1.65mg, phenoxazoline 25 μ g, and prostaglandin E per 200 μ l injection volume10.5. mu.g. Compound A is DEA/NO, compound B is prostaglandin E1(PGE1) Compound C is SPER/NO and compound D is SNP. FIG. 3 is a graph of penile length change versus dose (μ g/200 μ l) depicting the adverse effect of penile length change on intracavernosal NOates injection in anesthetized cats. Results are expressed as mean ± SEM of the change in penile length recorded after vehicle administration per animal. The control is papaverine 1.65 mg; phenolic amine oxazoline 25 μ g, and prostaglandin E10.5. mu.g in a 200. mu.l injection volume. Compound A is DEA/NO, compound B is prostaglandin E1(PGE1) Compound C is SPER/NO and compound D is SNP. The results show that: DEA/NO (Compound A), SNP (Compound D) and PGE1(Compound B) an increase in body pressure was obtained. SPER/NO (Compound C) achieves an increase in penile length at high doses. The effect of SPER/NO appears to be related to its relative potency and longer release rate of NO.
The results indicate the use of NONOates as NO donors for the treatment of erectile dysfunction. DEA/NO produces an erection with appropriate body pressure, penile size and duration, comparable to papaverine, phenoxazine and PGE1The corresponding effects of combination therapy, the latter has been successfully used to treat sexual dysfunction in men. The results show that: DEA/NO and SPER/NO together produce erection in a synergistic manner with rapid onset of action, substantial stiffness and long duration of action.
