Description

FIELD OF THE INVENTION

[0002] The present invention relates to quinoline compounds, to methods of using such compounds in treating cGMP-associated conditions such as erectile dysfunction, and to pharmaceutical compositions containing such compounds.

BACKGROUND OF THE INVENTION

[0003] Erectile dysfunction is the inability to obtain and maintain a penile erection sufficient for sexual intercourse or other sexual expression. A number of factors can place an individual at risk for this disorder, for example, trauma, pelvic surgery, hypercholesterolemia, ischemic heart disease, peripheral vascular disease, chronic renal failure, diabetes, the use of certain medicaments including some types of antihypertensive agents, digoxin, or the excessive use of narcotics, alcohol, tobacco, etc. Methods for treating erectile dysfunction include the use of vacuum devices and penile implants, as well as the administration of medicaments such as yohimbine, papaverine and apomorphine. Improved methods for treating this disorder are sought, however, as the aforementioned methods do not provide sufficient efficacy and/or are accompanied by drawbacks or side effects such as erosion, pain, priapism, or gastrointestinal discomfort.

[0004] A penile erection is dependent upon the presence of adequate levels of cyclic guanosine 3′,5′-monophosphate (cGMP), especially in corpora cavernosa tissue. Thus, administering an inhibitor of a cGMP phosphodiesterase (cGMP PDE), particularly a selective inhibitor of cGMP PDE Type 5 (PDE 5), provides a means for achieving and maintaining an erection and therefore, for treating erectile dysfunction. See Trigo-Rocha et al.,“Nitric Oxide and cGMP: Mediators of Pelvic Nerve-Stimulated Erection in Dogs,” Am. J. Physiol., Vol. 264 (Feb. 1993); Bowman et al.,“Cyclic GMP Mediates Neurogenic Relaxation in the Bovine Retractor Penis Muscle,” Br. J. Pharmac., 81, 665-674 (1984); and Rajfer et al.,“Nitric Oxide as a Mediator of Relaxation of the Corpus Cavernosum in Response to Nonadrenergic, Noncholinergic Neurotransmission,” New England J. Med., 326, 2, 90-94 (Jan. 1992). Sildenafil, for example, has been described as a PDE 5 inhibitor useful for treating erectile dysfunction. See Drugs of the Future, 22, 138-143 (1997).

[0005] Recent examples of other compounds claimed as PDE 5 inhibitors include fused pyridazine compounds (WO 96/05176 and U.S. patent application Ser. No. 09/393,833), anthranilic acid derivatives (U.S. 5,716,993), fused pyridopyridazine compounds (U.S. patent application Ser. No. 09/526,162), and quinazolinone compounds (U.S. Pat. No. 6,087,368).

[0006] The present invention provides compounds that are potent and selective inhibitors of cGMP PDE 5. These compounds may be employed in treating erectile dysfunction. In view of their activity, these compounds can also be used in treating other disorders responding to the inhibition of cGMP PDE, such as various cardiovascular disorders.

[0039] All stereoisomers of the present compounds, such as those, for example, which may exist due to asymmetric carbons on the R2 to R12 substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons) and diastereomeric forms, are contemplated and within the scope of this invention. Individual stereoisomers of the compounds of this invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations.

Thus, these compounds and compositions are useful in treating cGMP-associated conditions. A“cGMP-associated condition”, as used herein, denotes a disorder which can be treated by inhibiting cGMP PDE or elevating the level of cGMP in a subject, wherein treatment comprises prevention, partial alleviation, or cure of the disorder. Inhibition of cGMP PDE or elevation of the cGMP level may occur locally, for example, within certain tissues of the subject, or more extensively throughout the subject being treated for such a disorder. Treatment may be faciIitated wherein elevation of the cGMP level potentiates additional beneficial therapeutic effects, such as where elevation of the cGMP level potentiates the effects of endotheIium-derived relaxing factor.

[0162] The inventive compounds and compositions are useful for treating a variety of cardiovascular diseases including, but not Iimited to, hypertension, angina (stable, unstable, and variant), (congestive) heart failure, restenosis, atherosclerosis, and dyslipidemia, as well as reduced blood vessel patency, thrombus, both venous and arterial, myocardial infarction, peripheral vascular disease, stroke, bronchitis, chronic asthma, allergic asthma, allergic rhinitis, glaucoma, benign prostate hyperplasia (BPH),and forms of cancer responsive to the inhibition of cGMP PDE. In addition, these compounds are useful in treating sexual dysfunction in both men (erectile dysfunction, for example, due to diabetes melIitus, spinal cord injury, radical prostatectomy, psychogenic etiology or any other cause) and women by improving blood flow to the genitalia, especially, the corpus cavernosum. The compounds and compositions of this invention also are useful in treating diabetes melIitus and related conditions, and diseases of the gastrointestinal tract, such as those characterized by disorders of gut motility, including gastric paresis.

[0175] PDE Scintillation Proximity Assay Protocol

[0176] Sonicated human platelet homogenates are prepared by the method of Seiler, et al. (Seiler, S., Gillespie, E., Arnold, A. J., Brassard, C. L., Meanwell, N. A. and Fleming, J. S.,“Imidazoquinoline Derivatives: Potent Inhibitors of Platelet Camp Phosphodiesterase which Elevate Camp Levels and Activate Protein Kinase in Platelets,” Thrombosis Research, 62: 31-42 (1991)). PDE 5 is abundant in human platelets, and accounts for approximately 90% of the cGMP hydrolytic activity in the homogenates. When necessary, PDE 5 can be resolved from other PDE activities in the homogenates by anion exchange chromatography on a fast protein liquid chromatography system (FPLC) using a Mono-Q anion exchange column (Pharmacia) eluted with a linear gradient of 10 mM -450 mM NaCl.

[0177] The phosphodiesterase activity is assayed using a commercially available phosphodiesterase [3H]cGMP scintillation proximity (SPA) assay kit (Amersham). The manufacturer's protocol is followed explicitly except that the reactions are carried out at RT and 3 mM nonradioactive cGMP is included in the suspension of SPA beads to prevent the synthesis of any additional radioactive products.

6-Bromo-N-[(3-chloro-4-methoxyphenyl)methyl]-2-(2-pyridinyl)−4-quinolinamine

[0302] 336

[0303] To a suspension of 6-bromo2-(2-pyridine)quinoline-3-aminotbutyl ester (preparation 28) (300 mg) in DMF (10 mL) was added a solution of HMDSNa in THF (1M, 0.9 mL) at RT to generate a brown solution. Then 3 -chloro-4-methoxybenzyl chloride (160 mg) was added. The reaction mixture was stirred at RT for 2 h. An additional solution of HMDSNa in THF (0.9 mL) and 3-chloro-4-methoxybenzyl chloride (2 eq) was added and continue to stir. When the starting material was consumed, the reaction mixture was treated with TFA. Removal of the solvent and the residue was redissolved in EtOAc and washed with 1 N NaOH and water. Removal of the solvent and tritrated with Et2O to give the title compound (163 mg) as a Iight yellow solid. LC: 1.73′MH+: 454.
