The invention relates to new trisubstituted pyrazolo[4,3-d]pyrimidine derivatives and to their use in suitable utilities, especially diagnostic and therapeutic methods.The compounds are anticancer, anti-inflammatory, antiviral, antineurodegenerative, neurodepressive and immunosuppressive, they have improved selectivity and efficiency index, i.e. that are less toxic yet more efficacious than analogues known.It is an object of this invention to provide 3-, 5-, 7-trisubstituted pyrazolo[4,3-d]pyrimidines, which inhibit the cdks, cell proliferation, and/or induce apoptosis. A further object of the invention is to provide a method for inhibiting cell proliferation and inflammatory diseases to a mammal in need of an effective amount.The solution of this object are 3-, 5-, 7-trisubstituted pyrazolo[4,3-d]pyrimidines of the formula I.
