The present invention relates to a class of compounds represented by the formula:
or a pharmaceutically acceptable salt thereof, wherein W is the radical OR₁ wherein R₁ is hydrido, alkyl, phenyl, phenylalkyl which may be further substituted; or W is the amino radical of the formula NHOH; R₂ is hydrido, alkyl, alkenyl, cycloalkyl, cycloalkenyl which may be further substituted; or R₂ is phenyl, phenylalkyl, naphthyl, naphthylalkyl which may be further substituted; or R₂ is a heteromonocyclic ring structure having 5 or 6 ring carbon atoms wherein 1 or 2 of the ring carbon atoms are replaced by nitrogen, oxygen or sulfur and wherein the ring is selected from saturated, partially unsaturated, and fully unsaturated rings or a fused bicyclic ring structure having 10 to 12 ring carbon atoms wherein 1 to 3 of the ring carbon atoms may be replaced by nitrogen, oxygen or sulfur and each ring may independently be saturated, partially unsaturated or fully unsaturated which may be further stituted; R₃ and R₄ are each independently selected from hydrido, alkyl having 1 to 6 carbon atoms, hydroxy and halo; R₅ and R₆ are each independently selected from hydrido, alkyl having 1 to 6 carbon atoms, hydroxy, halo and alkoxy having 1 to 6 carbon atoms; and Y is alkyl having 1 to 6 carbon atoms, alkenyl having 2 to 6 carbon atoms, alkynyl having 2 to 6 carbon atoms or carbonylalkyl which may be further substituted.
Such compounds and compositions thereof have usefulness as inhibitors of platelet aggregation.
本发明涉及一类由式表示的化合物:
或其药学上可接受的盐,其中 W 是基 OR₁,其中 R₁ 是可被进一步取代的氢基、烷基、苯基、苯基烷基;或 W 是式 NHOH 的氨基;R₂ 是可被进一步取代的氢基、烷基、烯基、环烷基、环烯基;或 R₂ 是可被进一步取代的苯基、苯基烷基、萘基、萘基烷基;或 R₂ 是具有 5 或 6 个环碳原子的杂单环结构,其中 1 或 2 个环碳原子被氮、氧或硫取代,且该环选自饱和环、部分不饱和环和完全不饱和环,或具有 10 至 12 个环碳原子的融合双环结构,其中 1 至 3 个环碳原子可被氮、氧或硫取代,且每个环可独立为饱和环、部分不饱和环或完全不饱和环,可进一步被取代;R₃和 R₄各自独立地选自氢基、具有 1-6 个碳原子的烷基、羟基和卤基;R₅和 R₆ 各自独立地选自氢基、具有 1-6 个碳原子的烷基、羟基、卤基和具有 1-6 个碳原子的烷氧基;Y 是具有 1-6 个碳原子的烷基、具有 2-6 个碳原子的烯基、具有 2-6 个碳原子的炔基或可进一步取代的羰基烷基。
此类化合物及其组合物可用作血小板聚集抑制剂。
