Description: CYCLIC AMIDINO AGENTS USEFUL AS NITRIC OXIDE SYNTHASE INHIBITORS CIP of US 08/425,831 filed April 20, 1995, contents of which are herein incorporated by reference. Field of the Invention The present invention relates to amidino derivative compounds, pharmaceutical compositions containing these novel compounds, and to their use in therapy, in particular their use as nitric oxide synthase inhibitors. Background of the Invention It has been known since the early 1980's that the vascular relaxation brought about by acetycholine is dependent on the presence of the endothelium and this activity was ascribed to a labile humoral factor termed endothelium-derived relaxing factor (EDRF) . The activity of nitric oxide (NO) as a vasodilator has been known for well over 100 years and NO is the active component of amylnitrite, glyceryltrinitrite and other nitrovasodilators. The recent identification of EDRF as NO has coincided with the discovery of a biochemical pathway by which NO is synthesized from the amino acid L-arginine by the enzyme NO synthase. NO is the endogenous stimulator of the soluble guanylate cyclase and is involved in a number of biological actions in addition to endothelium-dependent relaxation including cytotoxicity of phagocytic cells and cell-to-cell communication in the central nervous system (see Moncada et al. Biochemical Pharmacology. 38. 1709-1715 (1989) and Moncada et al. Pharmacological Reviews. 43. 109-142 (1991) . It is now ' thought that excess NO production may be involved in a number of conditions, particularly conditions which involve systemic hypotension such as toxic shock and therapy with certain cytokines. The synthesis of NO from L-arginine can be inhibited by the L-arginine analogue, L-N-monomethyl- arginine (L-NMMA) and the therapeutic use of L-NMMA for the treatment of toxic shock and other types of systemic hypotension has been proposed (WO 91/04024 and GB-A- 2240041) . The therapeutic use of certain other NO synthase inhibitors apart from L-NMMA for the same purpose has also been proposed in WO 91/04024 and in EP- A-0446699. It has recently become apparent that there are at least three types of NO synthase as follows: (i) a constitutive, Ca ++ /calmodulin dependent enzyme, located in the endothelium, that releases NO in response to receptor or physical stimulation. (ii) a constitutive, Ca ++ /calmodulin dependent enzyme, located in the brain, that releases NO in response to receptor or physical stimulation. (iii) a Ca ++ independent enzyme which is induced after activation of vascular smooth muscle, macrophages, endothelial cells, and a number of other cells by endotoxin and cytokines. Once expressed this inducible NO synthase synthesizes NO for long periods. The NO released by the constitutive enzymes acts as a transduction mechanism underlying several physiological responses. The NO produced by the inducible enzyme is a cytotoxic molecule for tumor cells and invading microorganisms. It also appears that the adverse effects of excess NO production, in particular pathological vasodilation and tissue damage, may result largely from the effects of NO synthesized by the inducible NO synthase. There is also a growing body of evidence that NO may be involved in the degeneration of cartilage which takes place in certain conditions such as arthritis and it is also known that NO synthesis is increased in rheumatoid arthritis. Accordingly, further conditions in which there is an advantage in inhibiting NO production from L-arginine include autoimmune and/or inflammatory conditions affecting the joints, for example arthritis, inflammatory bowel disease, cardiovascular ischemia, diabetes, hyperalgesia (allodynia) , cerebral ischemia (both focal ischemia, thrombotic stroke and global ischemia, secondary to cardiac arrest) , and other CNS disorders mediated by NO. Futher conditions in which there is an advantage in inhibiting NO production from L-arginine include systemic hypotension associated with septic and/or toxic shock induced by a wide variety of agents; therapy with cytokines such as TNF, IL-1 and IL-2; and as an adjuvant to short term immunosuppression in transplant therapy. Further conditions in which there is an advantage in inhibiting NO production from L-arginine include autoimmune diseases and/or inflammatory conditions such as those affecting the joints, for example arthritis or ARDS or inflammatory bowel disease, or asthma, cardiovascular ischemia, congestive heart failure, myocarditis, artherosclerosis, migraine, reflux esophagitis, diarrhea, irritable bowel syndrome, cystic fibrosis, emphysema, diabetes, hyperalgesia (allodynia) cerebral ischemia (both focal ischemia, thrombotic stroke and global ischemia, secondary to cardiac arrest) and other CNS disorders mediated by NO, including opiate tolerance in patients needing protracted opiate analgesics, benzodiazepine tolerance in patients taking benzodiazepines, and other addictive behaviors for example nicotine and eating disorder. Some of the NO synthase inhibitors proposed for therapeutic use so far, and in particular L-NMMA, are non-selective in that they inhibit both the constitutive and the inducible NO synthase. Use of such a non- selective NO synthase inhibitor requires that great care be taken in order to avoid the potentially serious consequences of over-inhibition of the constitutive N0- synthase including hypertension and possible thrombosis and tissue damage. In particular, in the case of the therapeutic use of L-NMMA for the treatment of toxic shock it has been recommended that the patient must be subject to continuous blood pressure monitoring throughout the treatment. Thus, while non-selective NO synthase inhibitors have therapeutic utility provided that appropriate precautions are taken, NO synthase inhibitors which are selective in the sense that they inhibit the inducible NO synthase to a considerably greater extent than the constitutive isoforms of NO synthase would be of even greater therapeutic benefit and easier to use. W094/12165, WO94/14780, WO93/13055, EP0446699A1 and U.S. Patent No. 5,132,453 disclose compounds that inhibit nitric oxide synthesis and preferentially inhibit the inducible isoform of nitric oxide synthase.

Without further elaboration, it is believed that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent. Therefore the following preferred specific embodiments are to be construed as merely illustrative and not limitative of the remainder of the disclosure in any way whatsoever. All experiments were performed under either dry nitrogen or argon. All solvents and reagents were used without further purification unless otherwise noted. The routine work-up of the reactions involved the addition of the reaction mixture to a mixture of either neutral, or acidic, or basic aqueous solutions and organic solvent. The aqueous layer was extracted n times (x) with the indicated organic solvent. The combined organic extracts were washed n times (x) with the indicated aqueous solutions, dried over anhydrous Na 2 Sθ 4 , filtered, concentrated in vacuo , and purified as indicated. Separations by column chromatography were achieved with conditions described by Still. (Still, W. C. ; Kahn, M. ; Mitra, A. Rapid Chromatograhic Technique for Preparative Separation with Moderate Resolution. J. Org . Chem . , 1978, 43 , 2923-2925.)

Natl. Acad. Sci. U.S.A.. 87. 682-685, 1990 and Misko et al, Eur. J. EhamL-., 211. 119-125, 1993). Human inducible NOS (hiNOS) , human endothelial constitutive NOS (hecNOS) and human neuronal constitutive NOS (hncNOS) were each cloned from RNA extracted from human tissue. The cDNA for human inducible NOS (hiNOS) was isolated from a λcDNA library made from RNA extracted from a colon sample from a patient with ulcerative colitis. The cDNA for human endothelial constitutive NOS (hecNOS) was isolated from a λcDNA library made from RNA extracted from human umbilical vein endothelial cells (HUVEC) and the cDNA for human neuronal constitutive NOS (hncNOS) was isolated from a λcDNA library made from RNA extracted from human cerebellum obtained from a cadaver. The recombinant enzymes were expressed in Sf9 insect cells using a baculovirus vector (Rodi et al, in The Bioloσv of Nitric Qxifle, Pt. 4; Enzvmolocrv. Biochemistry and Immunology.- Moncada, S., Feelisch, M. , Busse, R., Higgs, E., Eds.; Portland Press Ltd.: London, 1995; pp 447-450). Enzyme activity was isolated from soluble cell extracts and partially purified by DEAE-Sepharose chromatography. To measure NOS activity, 10 μL of enzyme was added to 40 μL of 50 mM Tris (pH 7.6) in the presence or absence of test compounds and the reaction initiated by the addition of 50 μL of a reaction mixture containing 50mM Tris (pH 7.6), 2.0 mg/mL bovine serum albumin, 2.0 mM DTT, 4.0 mM CaCl2, 20 μM FAD, 100 μM tetrahydrobiopterin, 0.4-2.0 mM NADPH and 60 μM L-arginine containing 0.9 μci of L-[2,3- 3H] -arginine. The final concentration of L-arginine in the assay was 30 μM. For hecNOS, and hncNOS, calmodulin was included at a final concentration of 40-100 nM. Following incubation at 37° C for 15 minutes, the reaction was terminated by addition of 300 μL of cold stop buffer containing 10 mM EGTA, 100 mM HEPES, pH 5.5 and 1 mM citrulline. [3H] -Citrulline was separated by chromatography on Dowex 50W X-8 cation exchange resin and radioactivity determined with a liquid scintillation counter. Results are reported in Table I as the IC50 values of compounds for hiNOS, hecNOS and hncNOS. Compounds giving less than 50% inhibition at 100 μM were reported as having IC50 values of >100 μM and compounds giving greater than 50% inhibition at 100 μM were reported as having IC50 values of <100 μM. RAW cell nitrite assay RAW 264.7 cells are plated to confluency on a 96-well tissue culture plate grown overnight (17h) in the presence of LPS to induce NOS. A row of 3-6 wells were left untreated and served as controls for subtraction of nonspecific background. The media was removed from each well and the cells are washed twice with Krebs-Ringers- Hepes (25mM, pH 7.4) with 2 mg/ml glucose. The cells are then placed on ice and incubated with 50 μL of buffer containing L-arginine (30 μM) +/- inhibitors for lh. The assay is initiated by warming the plate to 37°C in a water bath for 1-2 h. Production of nitrite by intracellular iNOS is linear with time. To terminate the cellular assay, the plate of cells is placed on ice and the nitrite-containing buffer removed and analyzed for nitrite (Misko et al, Anal. Biochem.. 214, 11-16, 1993) . All values are the average of triplicate wells and are compared to a background-subtracted induced set of cells (100% value) . IC50 values of compounds with RAW cell mouse inducible NOS are reported in Table I. The following examples were assayed with the following results. Table I Compounds giving less than 50% inhibition at 100 μM were reported as having IC 50 values of >100 μM and compounds giving greater than 50% inhibition at 100 μM were reported as having IC 50 values of <100 μM. ιc 50 [μM] IP Vivo Assay Rats were treated with an intraperitoneal injection of 10-12.5 mg/kg of endotoxin (LPS) to induce systemic expression of inducible nitric oxide synthase, resulting in markedly elevated plasma nitrite/nitrate levels. Compounds were administered orally 1 hour prior to LPS administration and plasma nitrite/nitrate levels were determined 5 hours following LPS administration. As shown in Table II, both compounds inhibited the LPS induced increase in plasma nitrite/nitrate levels demonstrating the ability to inhibit inducible nitric oxide synthase activity in vivo.
