The present invention relates to beta-nitrostyrene compounds, and pharmaceutically acceptable salts and hydrates thereof having the following formula (I) and showing anticancer activity. Formula (I) wherein R1 to R5 are each independently any one selected from the group consisting of hydrogen, halogen, halogenated phenoxy and a radical of R6-Y-X- (-X- is -O- or -NH-, -Y- is -SO2-or -CO-, R6 is benzene substituted with at least any one selected from the group consisting of hydrogen, alkyl, halogen and NO2), or R3 forms a benzene ring along with R4; provided that R1, R2, R3, R4 and R5 are not hydrogen at the same time. These compounds can selectively inhibit the activity of telomerase specifically expressed in cancer cells and thus be used as an anticancer with minimized side effects of the conventional anticancer agents.
本发明涉及β-硝基苯乙烯化合物、其药学上可接受的盐和水合物,其具有以下式(I)并显示抗癌活性。其中,R1至R5各自独立地选自氢、卤素、卤代苯氧基和R6-Y-X-基团(-X-为-O-或-NH-,-Y-为-SO2-或-CO-,R6为苯基,其上至少有一种选自氢、烷基、卤素和NO2的取代基),或者R3与R4形成苯环;前提是R1、R2、R3、R4和R5不同时为氢。这些化合物可以选择性地抑制癌细胞特异表达的端粒酶活性,因此可用作抗癌药物,最大程度地减少传统抗癌药物的副作用。
