There are described compounds of formula I,
in which R1 represents benzofurazanyl, pyridyl or phenyl, the pyridyl or phenyl being substituted,
-COOR2 and -COOR3 are various ester groups,
Yand Ztogetherform a bond, and additionally, when R. is an electron withdrawing group Y may be hydrogen and Z may be hydroxy,
one of R7 and R. represents alkyl Cl to 6 and the other represents -CONR10R11; -CSNH2; -C(=NN)SR9; -S(O)mR9; phenyl optionally substituted by one or more of alkyl Cl to 6, halogen, alkoxy CI to 6 or nitro; alkyl Cl to 6 substituted by halogen; or furanyl,
or R7 and R. may be the same or different and each represents phenyl optionally substituted by one or more of alkyl CI to 6, halogen, alkoxy Cl to 6 or nitro; amino; alkyl CI to 6 substituted by halogen; -CN; -CH2OH; -CHO or-CH(OR9)2,
m is 0 or 1
R9 is alkyl CI to 6, and
R10 and R11 each independently represent hydrogen or alkyl Cl to 6, or together with the nitrogen atom to which they are attached form a 5 or 6 membered heterocyclic ring.
There are also described processes for making the compounds, and pharmaceutical, eg calcium antagonist, formulations containing them.
所述化合物为式 I、
其中 R1 代表苯并呋喃基、吡啶基或苯基,吡啶基或苯基被取代、
-COOR2和-COOR3是各种酯基、
Y和Z共同构成键,此外,当R.是取电子基团时,Y可以是氢,Z可以是羟基、
R7 和 R. 中的一个代表 Cl 至 6 烷基,另一个代表-CONR10R11;-CSNH2;-C(=NN)SR9;-S(O)mR9;任选被 Cl 至 6 烷基、卤素、CI 至 6 烷氧基或硝基中的一个或多个取代的苯基;被卤素取代的 Cl 至 6 烷基;或呋喃基、
或 R7 和 R.可以相同或不同,且各自代表被以下一种或多种任选取代的苯基:CI 至 6 号烷基、卤素、CI 至 6 号烷氧基或硝基;氨基;被卤素取代的 CI 至 6 号烷基;-CN;-CH2OH;-CHO 或-CH(OR9)2、
m为0或1
R9 是 CI-6 烷基,和
R10和R11各自独立地代表氢或Cl至6的烷基,或与它们所连接的氮原子一起形成5或6个成员的杂环。
此外,还介绍了制造这些化合物的工艺,以及含有这些化合物的药物制剂(如钙拮抗剂)。
