The invention relates to new 2,3,4-trinor-1,5-inter-m-phenylene-PGI.sub.2 derivatives of the formula (I) ##STR1## wherein A stands for carboxy, cyano, tetrazolyl or --COOR.sup.3 or --CONR.sup.1 R.sup.2 ; R.sup.3 is C.sub.1-4 alkyl or an equivalent of a pharmacologically acceptable cation: R.sup.1 and R.sup.2 each stands for hydrogen, phenyl; C.sub.1-5 alkyl, optionally substituted by carboxy, hydroxy, phenyl or C.sub.2-5 alkoxycarbonyl; or C.sub.1-4 alkylsulfonyl; or R.sup.1 and R.sup.2 together form an .alpha.,.omega.-alkylene chain containing 3-6 carbon atoms; B stands for oxygen or methylene; Y is optionally bromo-substituted vinylene or a --C.tbd.C-- group: R.sup.4 stands for hydrogen or tetrahydro-pyran-2-yl; R.sup.5 represents an alkyl group containing 5-9 carbon atoms, which can be optionally interrupted by one or more oxygen atom(s) or --CH.dbd.CH-- or --C.tbd.C-- group(s) and/or optionally substituted by halogen; or a phenyoxymethyl group optionally substituted by halogen or trifluoromethyl; or an alkenoyloxymethyl group containing 3-5 carbon atoms; R.sup.6 is hydrogen or C.sub.1-4 alkyl; R.sup.7 stands for hydrogen, halogen, cyano, C.sub.1-4 alkyl or C.sub.1-4 alkoxy; R.sup.8 is hydrogen, halogen, cyano, nitro, hydroxy or C.sub.2-5 alkanoylamido; with the proviso that if R.sup.5 stands for an alkyl group containing 5-9 carbon atoms which is unsubstituted or not interrupted by an oxygen atom or a --CH.dbd.CH-- or --C.tbd.C-- group; or a phenyoxymethyl group optionally substituted by halogen or trifluoromethyl, then either R.sup.7 or R.sup.8 is other than hydrogen, or A is other than carboxy or --COOR.sup.3 and a process for the preparation thereof. The new compounds of the Formula I exhibit prolonged cytoprotecting and aggregation inhibiting and a low hypotensive effect and are superior to prostacycline in the prolonged duration of their activity.
本发明涉及新的2,3,4-三去氧-1,5-相间-m-苯撑-PGI.sub.2衍生物,其化学式为(I):
其中,A代表羧基、氰基、四唑基或--COOR.sup.3或--CONR.sup.1R.sup.2;R.sup.3为C.sub.1-4烷基或药理学上可接受的阳离子等效物;R.sup.1和R.sup.2分别代表氢、苯基、C.sub.1-5烷基(可选地被羧基、羟基、苯基或C.sub.2-5烷氧羰基取代)或C.sub.1-4烷基磺酰基;或R.sup.1和R.sup.2一起形成一个含有3-6个碳原子的α,ω-烷基链;B代表氧或亚甲基;Y是可选溴代乙烯基或--C.tbd.C--基团;R.sup.4代表氢或四氢吡喃-2-基;R.sup.5表示含有5-9个碳原子的烷基,可以被一个或多个氧原子或--CH.dbd.CH--或--C.tbd.C--基团中断,也可以被卤素取代;或一个苯氧甲基基团,可选地被卤素或三氟甲基取代;或一个含有3-5个碳原子的烯酰氧甲基基团;R.sup.6为氢或C.sub.1-4烷基;R.sup.7代表氢、卤素、氰基、C.sub.1-4烷基或C.sub.1-4烷氧基;R.sup.8为氢、卤素、氰基、硝基、羟基或C.sub.2-5烷酰胺基;但是如果R.sup.5代表未被取代或不被氧原子或--CH.dbd.CH--或--C.tbd.C--基团中断的含有5-9个碳原子的烷基;或一个可选地被卤素或三氟甲基取代的苯氧甲基基团,则R.sup.7或R.sup.8必须不为氢,或者A不为羧基或--COOR.sup.3。本发明还涉及一种制备这些化合物的方法。化合物I的新化合物表现出延长的细胞保护和抑制聚集和低降压作用,并且在其活性的延长持续时间方面优于前列环素。
