A novel fused bicyclic pyridine derivative or a salt thereof that acts as a tachykinin receptor antagonist, in particular as an NK1 receptor antagonist, is represented by the following general formula (1):
wherein the rings A and B are each a benzene'ring which may have 1 to 3 substituents (any adjacent two of which may be bound to one another to form a ring);
the ring C is a nitrogen-containing ring having a hydrogen atom substituted with a nitrogen atom;
R1 and R2 are each independently a hydrogen atom, a C1 to C6 alkyl group, a C1 to C6 alkylsulfonyl group, a C1 to C6 alkylcarbonyl group, or a C1 to C6 alkoxycarbonyl group, or R1 and R2 are bound to one another to form the ring D; m is 1 or 2; n is 2 or 3; and q is an integer from 1 to 4.
一种可作为速激肽受体拮抗剂,特别是 NK1 受体拮抗剂的新型融合双环吡啶衍生物或其盐由下式(1)表示:
其中环 A 和环 B 各为苯环,可有 1 至 3 个取代基(其中任意相邻的两个可相互结合形成环);
环 C 是含氮环,其中有一个被氮原子取代的氢原子;
R1和R2各自独立地为氢原子、C1至C6烷基、C1至C6烷磺酰基、C1至C6烷羰基或C1至C6烷氧羰基,或R1和R2彼此结合形成环D;m为1或2;n为2或3;q为1至4的整数。
