Substituted amine derivatives represented by the general formula
wherein Q is -C-D-E-F-G-M- or -N-H-I-J-K-L- [C, D, E, F, G, H, I, J, K and L are each 0, S, a carbonyl group, -CHRa-, -Rb= or -NRc- (Ra, Rb and Rc are each H or a lower alkyl group), M and N are each an aromatic ring of 5-6 members optionally having a halogen, OH, LN, a lower alkyl group or a lower alkoxy group, provided that L is not 0, S, or -NRc-]; R is a heterocyclic ring of 5-6 members; R1 is H, a lower alkyl group, a lower haloalkyl group, a lower alkenyl group, a lower alkynyl group or a cycloalkyl group; R2, R3, R4, R5 R6 and R7 are each H, a halogen or a lower alkyl group or two of them denote a single bond; R8 and R9 are each F, CF3 or a lower alkyl group or are a cycloalkane in combination thereof; and R10 is H, F, CF3 an acetoxy group, a lower alkyl group or a lower alkoxy group. These compounds inhibit biosynthesis of cholesterol in mammals by inhibiting their squalene epoxidase, and thereby lower their blood cholesterol values. Therefore, these compounds are expected to be effective as an agent for treatment and prophylaxis of diseases caused by excess of cholesterol, for example, obesity, hyperlipemia and arteriosclerosis and heart and encephalic diseases accompanying them.
由通式代表的取代胺衍生物
其中 Q 为-C-D-E-F-G-M-或-N-H-I-J-K-L-[C、D、E、F、G、H、I、J、K 和 L 各为 0、S、羰基、-CHRa-、-Rb= 或-NRc-(Ra、Rb 和 Rc 各为 H 或低级烷基)、M 和 N 各为 5-6 个芳香环,可选择带有卤素、OH、LN、低级烷基或低级烷氧基,但 L 不得为 0、S 或-NRc-];R 是由 5-6 个成员组成的杂环;R1是H、低级烷基、低级卤代烷基、低级烯基、低级炔基或环烷基;R2、R3、R4、R5、R6和R7各自是H、卤素或低级烷基,或其中两个表示单键;R8和R9各自是F、CF3或低级烷基,或它们的组合是环烷烃;R10是H、F、CF3、乙酰氧基、低级烷基或低级烷氧基。这些化合物通过抑制哺乳动物体内的角鲨烯环氧化酶来抑制胆固醇的生物合成,从而降低血液中的胆固醇值。因此,这些化合物有望成为治疗和预防胆固醇过多引起的疾病(如肥胖症、高血脂症和动脉硬化以及伴随这些疾病的心脏和脑部疾病)的有效药物。
