Inhibitors of cyclin-dependent kinases, compositions and uses related thereto
The invention pertains to novel cyclin dependent kinase inhibitors (cdks) and specifically, but not exclusively, as inhibitors of cdk/cyclin complexes. As described herein, the inhibitors of this invention are capable of inhibiting the cell-cycle machinery and consequently may be useful in modulating cell-cycle progression, untimately controlling cell growth and differentiation. Such compounds would be useful for treating subjects having disorders associated with excessive cell proliferation.
1. A compound, or prodrug, tautomeric, pharmaceutically acceptable salt, N-oxide, or stereoisomeric form thereof, having the structure:
2. The compound of claim 1 , wherein the pharmaceutically acceptable salt form has the structure:
3. A pharmaceutical composition comprising a pharmaceutically acceptable excipient and a compound of claim 1 or 2 .
4. A method of treating an ovarian or colorectal cancer, comprising administering to an animal a compound of claim 1 or 2 .
5. A method of inhibiting proliferation of a cell in vitro, comprising contacting the cell with a compound of claim 1 or 2 .
6. A method of treating cyclin-dependent kinase associated disorders selected from ovarian and colorectal cancer, comprising administering to a host in need of such treatment a therapeutically effective amount of a compound of claim 1 or 2 or a composition containing a therapeutically effective amount of such compound.
