商品描述
Flavopiridol hydrochloride与ATP竞争性抑制CDKs，作用于CDK1，CDK2，CDK4和CDK6，无细胞试验中IC50为~40 nM。作用于CDK1/2/4/6比作用于CDK7选择性高7.5倍。Flavopiridol最初被发现可抑制EGFR和PKA。

In vitro(体外研究)
Flavopiridol is initially found to inhibit the epidermal growth factor receptor and protein kinase A (IC50 = 21 and 122 μM). Flavopiridol is later shown to inhibit cell proliferation, at more physiologically relevant concentrations (IC50 = 66 nM) when Flavopiridol is tested in the National Cancer Institute Development Therapeutics Program panel of 60 human tumor cell lines. Flavopiridol induces G1 arrest with inhibition of CDK2 and CDK4 in human breast carcinoma cells in a time and concentration dependent manner. Short time treatment of Flavopiridol (~12 hours) induce apoptosis in hematopoietic cell lines including SUDHL4, SUDHL6 (B-cell lines), Jurkat and MOLT4 (T-cell lines ), and HL60 (myeloid). In the clonogenic assay, Flavopiridol functions as a highly potent cytotoxic compound with a mean IC70 with 8 ng/mL in 23 human tumor models. A recent study shows Flavopiridol treatment induces a substantial AKT-Ser473 phosphorylation in human glioblastoma T98G cell line.
In vivo(体内研究)
At the maximal tolerated dose of 10 mg/kg/day administered p.o. on days 1-4 and 7-11, Flavopiridol effects tumor regression in PRXF1337 and tumor stasis lasting for 4 weeks in PRXF1369. After treatment with 7.5 mg/kg Flavopiridol bolus intravenous (IV) or intraperitoneal on each of 5 consecutive days, 11 out of 12 advanced stage subcutaneous (s.c.) human HL-60 xenografts undergo complete regressions, and animals remain disease-free several months after one course of Flavopiridol treatment. SUDHL-4 s.c. lymphomas treated with flavopiridol at 7.5 mg/kg bolus IV for 5 days undergo either major (two out of eight mice) or complete (four out of eight mice) regression, with two animals remaining disease-free for more than 60 days. The overall growth delay is 73.2%. Daily IV or IP administration of flavopiridol resultsin peak plasma levels of about 7 µM, followed by a progressive decline to approximately 100 nM in 8 hours.
