  • Patent number: 6559152
    Abstract: The present invention relates to the synthesis of a novel class of pyrazolo[3,4-d]pyrimidin-4-ones of formula (I), alternatively represented by the tautomer (II): that are potent inhibitors of the class of enzymes known as cyclin dependent kinases, which relate to the catalytic subunits cyclin dependent kinase 1-8 and their regulatory subunits know as cyclins A-H, K, N, and T. This invention also provides a novel method of treating cancer or other proliferative diseases by administering a therapeutically effective amount of one of these compounds or a pharmaceutically acceptable salt form thereof. Alternatively, one can treat cancer or other proliferative diseases by administering a therapeutically effective combination of one of the compounds of the present invention and one or more other known anti-cancer or anti-proliferative agents.
