Flavopiridol

Flavopiridol (Alvocidib) is a potent inhibitor of CDKs 1, 2 and 4 in cell-free assays (IC50 in the region of 100 nM) and tumour cell growth in vitro (typical IC50 in the region of 100 nM). Flavopiridol is effective in inducing cell cycle arrest and cytotoxicity in rhabdoid tumors. Its effects are correlated with the down-regulation of cyclin D1 and the up-regulation of p21. Flavopiridol is potentially a novel chemotherapeutic agent for rhabdoid tumors.
