There are described compounds of formula I, ##STR1## in which R.sub.1 represents benzofurazanyl, pyridyl or phenyl, the pyridyl or phenyl being substituted, --COOR.sub.2 and --COOR.sub.3 are various ester groups, one of R.sub.7 and R.sub.8 represents alkyl Cl to 6 and the other represents --CONR.sub.10 R.sub.11 ; --CSNH.sub.2 ; --C(.dbd.NH)SR.sub.9 ; --S(O).sub.m R.sub.9 ; phenyl optionally substituted by one or more of alkyl Cl to 6, halogen, alkoxy Cl to 6 or nitro; alkyl Cl to 6 substituted by halogen; or furanyl; m is 0 or 1 R.sub.9 is alkyl Cl to 6, and R.sub.10 and R.sub.11 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, e.g. calcium antagonist, formulations containing them.
描述了一系列化合物的化学式I,其中R.sub.1代表苯并呋喃基、吡啶基或苯基,吡啶基或苯基被取代,--COOR.sub.2和--COOR.sub.3是不同的酯基,R.sub.7和R.sub.8中的一个代表烷基Cl至6,另一个代表--CONR.sub.10 R.sub.11;--CSNH.sub.2;--C(.dbd.NH)SR.sub.9;--S(O).sub.mR.sub.9;苯基选择性地被取代为1个或多个烷基Cl至6、卤素、烷氧基Cl至6或硝基;被卤素取代的烷基Cl至6;或呋喃基;m为0或1,R.sub.9为烷基Cl至6,R.sub.10和R.sub.11各自独立地表示氢或烷基Cl至6,或者与它们所附着的氮原子一起形成5或6元杂环环。还描述了制备这些化合物的过程以及包含它们的制药配方,例如钙拮抗剂。
