The flavone, flavopiridol (Alvocidib) (6; Scheme 1), is
totally synthetic, but, as discussed in section 1, its novel
structure is based on the natural product rohitukine (7;
Scheme 1) isolated from Dysoxylum binectariferum. Flavopiridol
was originally considered to be an inhibitor of
cyclin-dependent kinases (the regulators of the G2 to M
transition in the cell cycle) and was entered into phase I and
then phase II clinical trials against a broad range of tumors.
It has now been reported to be a very potent inhibitor of
CDK-7 and -9, the kinases primarily responsible for promoting
RNAP II (RNA polymerase II) activity, thus involving
these agents in the transcription process. The molecular
targets/interactions involved in the transcription processes
and flavopiridol interactions have been reviewed. Currently
(early 2009), the compound is reported to be in nine
clinical trials ranging from phase I to phase II covering
leukemias, lymphomas, and solid tumors either as single
agent or in combination with other anticancer agents in the
NCI’s clinical trial Web site and is reported in the Prous
Integrity database to be in phase III trials under the auspices
of Sanofi-Aventis
