The invention relates to new arylazo compounds of the
wherein R, and R2 independently of each other represent hydrogen or C1-3-alkyl, R3 represent hydrogen, halogen, C1-3-alkyl, C1-3-alkoxy, carboxy, C1-3-alkoxycarbonyl, C1-3- alkylcarbonyl or a group X-NH-SO2-, wherein X represents a heterocyclic ring, R4 represents hydrogen, halogen or C1-3- alkyl, and n is the integer 1 or 2, the two groups
being the same or different when n is 2, and lactones and salt thereof. The compounds of formula I have a high inhibiting effect on prostaglandin synthetizing and inactivating enzymes and may therefore be used as a drug and anti-fertility agent. The invention also relates to preparation of the compounds of formula I as well as pharmaceutical compositions containing the same.
本发明涉及下列新芳基偶氮化合物
其中 R 和 R2 各自代表氢或 C1-3-烷基,R3 代表氢、卤素、C1-3-烷基、C1-3-烷氧基、羧基、C1-3-烷氧基羰基、C1-3-烷基羰基或基团 X-NH-SO2-,其中 X 代表杂环,R4 代表氢、卤素或 C1-3-烷基,n 为整数 1 或 2,当 n 为 2 时,两个基团相同或不同。
内酯及其盐。式 I 的化合物对
前列腺素合成酶和灭活酶有很强的抑制作用,因此可用作药物和抗生育剂。本发明还涉及式 I 化合物的制备以及含有该化合物的药物组合物。
