Alvocidib (INN; also known as Flavopiridol) is a flavonoid alkaloid CDK9 kinase inhibitor under clinical development for the treatment of acute myeloid leukemia, by Tolero Pharmaceuticals, Inc. It has been studied also for the treatment of arthritis[1] and atherosclerotic plaque formation[2] The target of Flavopiridol is the positive transcription elongation factor P-TEFb.[3][4] Treatment of cells with Flavopiridol leads to inhibition of P-TEFb and the loss of mRNA production.[5][6]

The compound is a synthetic analog of natural product rohitukine which was initially extracted from Amoora rohituka [syn. Aphanamixis polystachya] and later from Dysoxylum binectariferum.[7][8]

Orphan drug

“

Tolero Pharmaceuticals Inc. announced that the FDA has granted orphan drug designation for Alvocidib, its cyclin-dependent kinase small molecule inhibitor, for the treatment of patients with acute myeloid leukemia.[9]
