The present invention is concerned with novel anticancer agents having potent antineoplastic activity without systemic toxicity and mutagenicity. The novel anticancer agents of the present invention are derivatives of formula I: ##STR1## wherein: A is O or NH; and B is an aryl group selected from the group consisting of phenyl, indane, fluorene, indazole, indole, and pyridine, the aryl group being substituted with at least one substituent selected from the group consisting of hydrogen, C.sub.1-16 alkyl optionally substituted with one or more OH or SH, lower alkoxy, C.sub.3-6 cycloalkyl, lower alkylthio, nitro, cyano, lower alkene, lower alkyne, OH, SH, carboxy lower alkyl, carboxy lower alkyl esters, amino, N-lower alkyl, N,N-dilower alkyl and halogen; or a prodrug thereof, with the provisos that when A is NH and B is phenyl: a) B is substituted with at least one substituent other than hydrogen; b) B is not: 1) mono-substituted in the 4 position with C.sub.1-2 alkyl, tert-butyl or n-butyl, halogen, OH, carboxy C.sub.0-3 alkyl, (CH.sub.2).sub.3 COOCH.sub.3, cyano, acetyl and methylthio; and 2) substituted with one or two identical substituents selected from the group consisting of methyl, halogen, nitro, methoxy, carboxy and C.sub.0-3 alkyl COOH, the remaining substituents being hydrogen atoms.
本发明涉及具有强大抗肿瘤活性而无系统毒性和诱变性的新型抗癌剂。本发明的新型抗癌剂是公式I的衍生物:其中:A为O或NH;B为从苯基、茚基、芴基、吲唑基、吲哚基和吡啶基中选择的芳基,该芳基被至少一个取代基所取代,所述取代基被选择自氢、C.sub.1-16烷基(可以选择地取代一个或多个OH或SH)、低烷氧基、C.sub.3-6环烷基、低硫基、硝基、氰基、低烯烃基、低炔烃基、OH、SH、羧基的低烷基、羧基的低烷基酯、氨基、N-低烷基、N,N-二低烷基和卤素;或其前体药物,条件是当A为NH且B为苯基时:a)B被至少一个非氢取代基取代;b)B不是:1)在4位被C.sub.1-2烷基、叔丁基或正丁基、卤素、OH、羧基的C.sub.0-3烷基、(CH.sub.2).sub.3 COOCH.sub.3、氰基、乙酰基和甲硫基单取代;2)被选择自甲基、卤素、硝基、甲氧基、羧基和C.sub.0-3烷基COOH的一个或两个相同取代基取代,其余取代基为氢原子。
