The present invention relates to propenone derivatives represented by the following formula (I):
wherein R1 represents hydrogen or lower alkyl; R2 and R3 independently represent hydrogen, lower alkyl, or substituted or unsubstituted aralkyl, or alternatively R2 and R3 are combined to form substituted or unsubstituted methylene or ethylene; R4 represents hydrogen, hydroxy, lower alkyl, substituted or unsubstituted aralkyl, lower alkoxy, substituted or unsubstituted aralkyloxy, or halogen; and X represents substituted or unsubstituted indolyl, with the proviso that when OR3 is on the position 2 or position 6 of the benzene ring, R3 is not hydrogen; that when R4 is on the position 2 or position 6 of the benzene ring, R4 is not hydroxy; and that the combination of OR2, OR3, and R4 is not 3,4-dimethoxy or 3,4,5-trimethoxy; or pharmaceutically acceptable salts thereof.
本发明涉及下式(I)所代表的丙烯酮衍生物:
其中 R1 代表氢或低级烷基;R2 和 R3 独立地代表氢、低级烷基或取代或未取代的烷基,或者 R2 和 R3 结合形成取代或未取代的亚甲基或亚乙基;R4 代表氢、羟基、低级烷基、取代或未取代的烷基、低级烷氧基、取代或未取代的烷氧基或卤素;X代表取代或未取代的吲哚基,但当 OR3 位于苯环的第 2 位或第 6 位时,R3 不是氢;当 R4 位于苯环的第 2 位或第 6 位时,R4 不是羟基;且 OR2、OR3 和 R4 的组合不是 3,4-二甲氧基或 3,4,5-三甲氧基;或其药学上可接受的盐。
