Abstract: This present invention relates to compounds of formula (I) wherein G, R<1> and R<2> are defined as in the specification that exhibit activity as nitric oxide synthase (NOS) inhibitors, to pharmaceutical compositions containing them and to their use in the treatment and prevention of central nervous system and other disorders.

Description: 2-AMINO-6- 2-SUBSTITUTED^-PHENOXYVSUBSTITUTED-PYRIDINES The present invention relates to certain 2-amιno-6-(2-substιtuted-4-phenoxy)- substituted-pyndines that exhibit activity as nitric oxide synthase (NOS) inhibitors to pharmaceutical compositions containing them and to their use in the treatment and prevention of central nervous system disorders, inflammatory disorders, septic shock and other disorders There are three known isoforms of NOS - an inducible form (l-NOS) and two constitutive forms referred to as, respectively, neuronal NOS (N-NOS) and endothelial NOS (E-NOS) Each of these enzymes carries out the conversion of arginine to αtrulline while producing a molecule of nitric oxide (NO) in response to various stimuli It is believed that excess nitric oxide (NO) production by NOS plays a role in the pathology of a number of disorders and conditions in mammals For example, NO produced by l-NOS is thought to play a role in diseases that involve systemic hypotension such as toxic shock and therapy with certain cytokmes It has been shown that cancer patients treated with cytokmes such as interleukin 1 (IL-1 ), interleukin 2 (IL-2) or tumor necrosis factor (TNF) suffer cytokine-induced shock and hypotension due to NO produced from macrophages, j_e_, inducible NOS (l-NOS), see Chemical & Engineering News, Dec 20, p 33, (1993) l-NOS inhibitors can reverse this It is also believed that l-NOS plays a role in the pathology of diseases of the central nervous system such as ischemia For example, inhibition of l-NOS has been shown to ameliorate cerebral ischemic damage in rats, see Am J Physiol , 268, p R286 (1995)) Suppression of adjuvant induced arthritis by selective inhibition of l-NOS is reported in Eur J Pharmacol , 273, p 15-24 (1995) NO produced by N-NOS is thought to play a role in diseases such as cerebral ischemia, pain, and opiate tolerance For example inhibition of N-NOS decreases infarct volume after proximal middle cerebral artery occlusion in the rat, see J Cerebr Blood Flow Metab , 14, p 924-929 (1994) N-NOS inhibition has also been shown to be effective in antinociception, as evidenced by activity in the late phase of the formalin-induced hindpaw licking and acetic acid- induced abdominal constriction assays, see Br J Pharmacol . 110. p 219-224 (1993) Finally opioid withdrawal in rodents has been reported to be reduced by N-NOS inhibition, see Neuropsvchopharmacol , 13, p 269-293 (1995) Other NOS inhibitors and their utility as pharmaceutical agents in the treatment of CNS and other disorders are referred to

illustrated above, pressure is not critical unless otherwise indicated Pressures from about 0 5 atmospheres to about 5 atmospheres are generally acceptable, and ambient pressure, i_e_, about 1 atmosphere, is preferred as a matter of convenience The compounds of formula I ("the active compounds of this invention") which are basic in nature are capable of forming 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 a compound of the formula I 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 a pharmaceutically acceptable acid addition salt The acid addition salts of the active base compounds of this invention are readily prepared by treating the base compound with a substantially equivalent amount of the chosen mineral or organic acid 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 readily obtained The active compounds of this invention and their pharmaceutically acceptable salts are useful as NOS inhibitors j_e_, they possess the ability to inhibit the NOS enzyme in mammals, and therefore they are able to function as therapeutic agents in the treatment of the aforementioned disorders and diseases in an afflicted mammal The active compounds of this invention and their pharmaceutically acceptable salts can be administered via either the oral, parental or topical routes In general, these compounds are most desirably administered in dosages ranging from about 0 01 to about 250 mg per day, in single or divided doses (j_e_, from 1 to 4 doses per day), although variations will necessarily occur depending upon the species, weight 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 0 07 mg to about 21 mg per kg of body weight per day is most desirably employed Variations may nevertheless occur depending upon the species of animal 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 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 effect, provided that such larger doses are first divided into several small doses for administration throughout the day The active compounds of the invention may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by either of the three routes previously indicated, and such administration may be carried out in single or multiple doses More particularly, the novel therapeutic agents of this invention can be administered in a wide variety of different dosage forms, j_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, jellies, gels, pastes, lotions, ointments, aqueous suspensions, injectable solutions, elixirs, syrups, and the like Such carriers include solid diluents or
