titleOfInvention | Camptothecin derivatives and process for preparing same |
abstract | New camptothecin derivatives and a process for preparing same are disclosed, which are represented by the general formula: <CHEM> wherein R<1> represents a lower alkyl group, R<2> represents a hydrogen atom or an amino, hydroxyl, lower acylamino or lower alkoxy group, R<3> represents a hydrogen or halogen atom or a lower alkyl, hydroxyl, lower alkoxy, nitro, amino, cyano or di(lower alkyl)amino group, R<4> represents a hydrogen or halogen atom or a lower alkyl, hydroxyl, lower alkoxy, lower alkylthio, amino, cyano or di(lower alkyl)amino group, and R<5> represents a hydrogen or halogen atom or a hydroxyl or lower alkoxy group, with the proviso that all of the R<2>, R<3>, R<4> and R<5> substituents should not be a hydrogen atom and also that if any one of the R<2>, R<3>, R<4> and R<5> is a hydroxyl or lower alkoxy group, all of the other three substituents should not be a hydrogen atom. The new camptothecin derivatives are useful as anti-tumor drugs or intermediates therefor. |
