Description
| - The invention relates to 3-,5-,7-trisubstituted pyrazolo(4,3-d)pyrimidines represented by the general formula (I), and substituted alkyl, cycloalkyl, cycloheteroalkyl, cycloalkyl, alkyl, aryl or alkylaryl group, R5 is halogen, -NHNH2, -NHOH, NHCONH2, guanylo (NH-C(NH)NH2) an optionally substituted C1-C6 alkyl, alkenyl, alkinyl, C3-C15 cycloalkyl, Rf (C3-C15 cycloalkyl), heterocycle, heteroalkyl, aryl, heteroaryl, arylalkyl, cycloheteroalkyl, cycloheteroalkyl alkyl, heteroarylalkyl group etc.This invention relates to new pyrazolo(4,3-d)pyrimidine derivatives and to their use in suitable utilities, especially diagnostic and therapeutic methods. More specifically, the present invention also relates to the use of 3,5,7-trisubstituted pyrazolo(4,3-d)pyrimidines or a pharmaceutically acceptable salt thereof in combination with cytostatics in the preparation of a medicament for treating cancer.
