The invention concerns novel 4-phenyl-1,3-dioxan-5-ylalkenoic acid derivatives of the formula I having cis relative stereochemistry at positions 4 and 5 of the dioxane ring and wherein Ra and Rb are variously hydrogen, alkyl, halogenoalkyl, alkenyl, and optionally substituted aryl or arylalkyl, Rc is hydroxy, alkoxy or alkanesulphonamido, n is 1 or 2, A is ethylene or vinylene, Y is (2-5C)polymethylene optionally substituted by alkyl, and benzene ring B is optionally substituted phenyl, or, when Rc is hydroxy, a salt thereof. The acid derivatives antagonize one or more of the actions of thromboxane A.sub.2 (TXA.sub.2) and are expected to be of value in those disease conditions in which TXA.sub.2 is involved. The invention also provides pharmaceutical compositions containing an acid derivative of formula I, and processes for their chemical production.
该发明涉及具有二氧杂环戊烷环上4和5位处顺式相对立体化学的新型4-苯基-1,3-二氧杂环戊烯酸衍生物,其中Ra和Rb可以是氢、烷基、卤代烷基、烯基,也可以是可选择地取代的芳基或芳基烷基,Rc是羟基、烷氧基或烷磺酰胺基,n为1或2,A为乙烯或乙烯基,Y为(2-5C)聚亚甲基,可选择地被烷基取代,苯环B可选择地被取代的苯基,或者当Rc为羟基时,其盐。这些酸衍生物拮抗血栓素A.sub.2(TXA.sub.2)的一个或多个作用,并预计在TXA.sub.2参与的疾病情况中具有价值。该发明还提供含有式I的酸衍生物的药物组合物,以及它们的化学生产方法。
