The invention provides compounds of the formula
wherein
R1 is hydrogen or halogen;
R2 is hydrogen, halogen, lower alkyl or lower alkoxy;
R1 and R2 may together be —CH═CH—CH═CH—, wherein R1 and R2 together with the two carbon ring atoms to which they are attached form a fused ring;
R3 is halogen, trifluoromethyl, lower alkyl or lower alkoxy;
R4/R4′ are each independently hydrogen or lower alkyl;
R5 is lower alkyl, lower alkoxy, amino, phenyl, hydroxy-lower alkyl, cyano-lower alkyl, carbamoyl-lower alkyl, pyridyl, pyrimidyl, —(CH2)n-piperazinyl, which is optionally substituted by one or two lower alkyl groups or by hydroxy-lower alkyl, —(CH2)n-morpholinyl, —(CH2)n-piperidinyl, —(CH2)n+1-imidazolyl, lower alkyl-sulfanyl, lower alkyl-sulfonyl, benzylamino, —NH—(CH2)n+1N(R4″)2, —(CH2)n+1N(R4″)2, —O—(CH2)n+1-morpholinyl, —O—(CH2)n+1-piperidinyl or —O—(CH2)n+1N(R4″)2, wherein R4″ is hydrogen or lower alkyl; and
n is 0-2;
X is —C(O)N(R4″)— or —N(R4″)C(O)—;
and to pharmaceutically acceptable acid addition salts thereof.
It has been shown that the compounds have a good affinity to the NK-1 receptor and may therefore used for the treatment of diseases related to this receptor.
该发明提供了以下式化合物,其中R1为氢或卤素;R2为氢、卤素、低烷基或低烷氧基;R1和R2可能一起是—CH═CH—CH═CH—,其中R1和R2与它们附着的两个碳环原子一起形成一个融合环;R3为卤素、三氟甲基、低烷基或低烷氧基;R4/R4′各自独立地为氢或低烷基;R5为低烷基、低烷氧基、氨基、苯基、羟基-低烷基、氰基-低烷基、氨基甲酰基-低烷基、吡啶基、嘧啶基、—(CH2)n-哌嗪基,可选择地被一个或两个低烷基基团或羟基-低烷基取代,—(CH2)n-吗啉基,—(CH2)n-哌啶基,—(CH2)n+1-咪唑基,低烷基硫醚基,低烷基磺酰基,苄氨基,—NH—(CH2)n+1N(R4″)2,—(CH2)n+1N(R4″)2,—O—(CH2)n+1-吗啉基,—O—(CH2)n+1-哌啶基或—O—(CH2)n+1N(R4″)2,其中R4″为氢或低烷基;n为0-2;X为—C(O)N(R4″)—或—N(R4″)C(O)—;以及其药学上可接受的酸盐。已经证明这些化合物对NK-1受体具有良好的亲和力,因此可以用于治疗与该受体相关的疾病。
