摘要:
There are provided novel compounds of formula (I) wherein A, R?1, R3, R4, R5¿, T, U, V, W, X and Y are as defined in the specification, and pharmaceutically acceptable salts thereof; together with processes for their preparation, compositions containing them and their use in therapy. The compounds are inhibitors of nitric oxide synthase and are thereby particularly useful in the treatment or prophylaxis of inflammatory diseases, pain and CNS diseases.
摘要:
Disclosed are compounds of formula (I), and the pharmaceutically acceptable salts thereof wheren Q, X, Y, Z, and R1 R9, and R12-R19 are defined herein. These compounds are selective modulators of MCH 1 receptors that are, therefore, useful in the treatment of a variety of metabolic, feeding, and sexual disorders. Methods of treatment of such disorders and well as packaged pharmaceutical compositions are also disclosed.
