The present invention relates to novel isoxazole and thiazole compounds having an excellent lysophosphatidic acid (LPA) receptor antagonistic activity represented by general formula [1] or salts thereof:
1
wherein R1 and R2 represents an optionally substituted alkyl group or the like; R3 represents a hydrogen atom or the like; R4 represent a group selected from the group consisting of (I) optionally substituted phenyl, aryl, or heterocycle, (II) substituted or nonsubstituted alkyl, and (III) substituted or nonsubstituted alkenyl, alternatively, R3 and R4 may form a ring structure together with a carbon atom to which they bind; and X represents an oxygen atom or a sulfur atom, provided that, when R3 is a hydrogen atom, R4 represents a group other than methyl, and the use thereof as a medicine.
本发明涉及一种新型异噁唑和噻唑化合物,其具有优异的溶血磷脂酸(LPA)受体拮抗活性,通式为[1]或其盐:其中,R1和R2代表可选取代的烷基或类似物;R3代表氢原子或类似物;R4代表从(I)可选取代的苯基、芳基或杂环基,(II)取代或未取代的烷基,以及(III)取代或未取代的烯基中选择的基团,或者R3和R4可以与它们所结合的碳原子一起形成环状结构;X代表氧原子或硫原子,前提是当R3是氢原子时,R4代表甲基以外的基团,以及其作为药物的用途。
