This compound exhibits antiproliferative effects in both hematologic and solid tumor cells. Additionally, CDK HDAC-IN-4 induces apoptosis and S-phase cell cycle arrest in MV-4-11 cells. It has also demonstrated significant antitumor efficacy in an MV-4-11 xenograft model.

Flavopiridol (Alvocidib) (Alvocidib) competes with ATP to inhibit CDKs including CDK1, CDK2, CDK4 and CDK6 with IC50 of ~ 40 nM. It is 7.5-fold more selective for CDK1, 2, 4, 6 versus CDK7. Flavopiridol is initially found to inhibit EGFR and PKA. Phase 1/2.

Nimbolide suppresses CDK4 CDK6 kinase activity. Nimbolide inhibits the NF-κB, Wnt, PI3K-Akt, MAPK, and JAK-STAT signaling pathways. Nimbolide causes apoptosis through the inactivation of NF-κB. Nimbolide is a triterpene derived from the leaves and flowers

Flavopiridol hydrochloride (MDL 107826A) is a synthetic N-methylpiperidinyl chlorophenyl flavone compound. As an inhibitor of cyclin-dependent kinase, alvocidib induces cell cycle arrest by preventing phosphorylation of cyclin-dependent kinases (CDKs) and by down-regulating cyclin D1 and D3 expression, resulting in G1 cell cycle arrest and apoptosis. This agent is also a competitive inhibitor of adenosine triphosphate activity.
