There are described compounds of formula I,
in which R2 and R3, which may be the same or different, each represent alkyl C1 to 6 or cycloalkyl C3 to 8,
R7 and R8, which may be the same or different, each represent alkyl C1 to 6 optionally substituted by halogen, and
X, Y and Z, which may be the same or different, are each hydrogen, halogen, nitro or alkyl C1 to 6 optionally substituted by halogen, or Z is as defined above and X and Y, together with the carbon atoms to which they are attached, form a C5 to 8 carbocyclic ring, other than a benzene ring,
provided that when R2, R3, R7 and R8 are all methyl and X and Z are hydrogen; or when R2 and R3 are both ethyl, R7 and R8 are both methyl and X and Z are hydrogen; then Y is other I than methyl.
There are also described methods for making the compounds and their formulation and use as pharmaceuticals, e.g. for the treatment of cardiovascular conditions.
所述化合物为式 I、
其中 R2 和 R3 可以相同或不同,各自代表 C1-6 烷基或 C3-8 环烷基、
R7 和 R8(可以相同或不同)各自代表 C1-6 烷基,可选被卤素取代,以及
X、Y 和 Z(可以相同或不同)各自为氢、卤素、硝基或任选被卤素取代的 C1 至 6 烷基,或 Z 如上文所定义,且 X 和 Y 与它们所连接的碳原子一起形成 C5 至 8 碳环(苯环除外)、
条件是当 R2、R3、R7 和 R8 均为甲基,且 X 和 Z 均为氢时;或当 R2 和 R3 均为乙基,R7 和 R8 均为甲基,且 X 和 Z 均为氢时;则 Y 为甲基以外的其他 I。
此外,还介绍了这些化合物的制造方法及其配制和用作药物的方法,例如用于治疗心血管疾病。
