The invention concerns novel 1,3-dioxane alkenoic acid derivatives of the formula I ##STR1## wherein: n is the integer 1 or 2; Y is methyleneoxy, vinylene or ethylene; A.sup.1 is (1-6C)alkylene; R.sup.1 is a group of the formula R.sup.2.A.sup.2 -, in which: R.sup.2 is phenyl unsubstituted or bearing up to three substituents which are independently selected from (1-6C)alkyl, (1-6C)alkoxy, (2-6C)alkanoyl, (1-6C)alkylthio, (1-6C)alkylsulphonyl, halogeno, trifluoromethyl, nitro and cyano; A.sup.2 is a direct bond to R.sup.2 or a group of the formula --W--C(R.sup.4)(R.sup.5)-- wherein W is oxygen, methylene or a direct bond to R.sup.2, and R.sup.4 and R.sup.5 are independently (1-4C)alkyl; Q is a heterocyclyl group selected from thiazol-5-yl and imidazol-5-yl, the latter being unsubstituted or bearing a (1-12C)alkyl group at the 1-position of the imidazole ring; and R.sup.3 is hydroxy, a physiologically acceptable alcohol residue, or (1-4C)alkanesulphonamido; or a pharmaceutically acceptable salt thereof. The compounds are thromboxane A.sub.2 antagonists and inhibitors of thromboxane A.sub.2 synthase, and are useful on the treatment of a variety of diseases in which thromboxane A.sub.2 is involved, such as is ischaemic heart disease, cerebrovascular disease and peripheral vascular disease. The invention also includes processes for the manufacture and use of the compounds, and pharmaceutical compositions containing them.
本发明涉及公式I的新型1,3-二氧杂环己烯酸衍生物,其中:n是整数1或2;Y是亚甲氧基、乙烯基或乙烷基;A1是(1-6C)烷基;R1是公式R2.A2-的基团,在其中:R2是苯基,未取代或带有最多三个取代基,所述取代基独立地选自(1-6C)烷基、(1-6C)烷氧基、(2-6C)酰基、(1-6C)烷硫基、(1-6C)烷基磺酰基、卤素、三氟甲基、硝基和氰基;A2是直接键到R2或公式--W--C(R4)(R5)--的基团,其中W是氧、亚甲基或直接键到R2,且R4和R5独立地是(1-4C)烷基;Q是从噻唑-5-基和咪唑-5-基中选择的杂环基团,后者在咪唑环上的1-位置带有(1-12C)烷基或未取代;R3是羟基、生理上可接受的醇残基或(1-4C)烷基磺酰胺基;或其药学上可接受的盐。该化合物是血栓素A2拮抗剂和血栓素A2合酶抑制剂,在治疗包括缺血性心脏病、脑血管疾病和外周血管疾病等多种与血栓素A2有关的疾病中有用。本发明还包括制造和使用该化合物的方法,以及含有它们的制药组合物。
