生物活性

Flavopiridol (Alvocidib)与ATP竞争性抑制CDKs,包括CDK1, CDK2, CDK4和CDK6,IC50约为40 nM。作用于CDK1, 2, 4, 6比作用于CDK7选择性强7.5倍。Flavopiridol最初被发现能抑制EGFR和PKA。作为CDK广谱抑制剂,Flavopiridol可以抑制细胞周期进展,使其停在G1期或G2期。0.3 μM Flavopiridol作用于MCF-7或MDA-MB-468细胞,通过抑制CDK4或CDK2激酶活性,而诱导细胞周期停在G1 期。 Flavopiridol 作用于无关激酶,如MAP, PAK, PKC, 和 EGFR,活性低很多,IC50 >14 μM。

细胞实验
细胞系ovarian tumor cell line A2780/ DDP-S
方法72 h Proliferation Assay. In vitro cytotoxicity was assessed in tissue culture cells by MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfenyl)-2H-tetrazolium, inner salt) assay as previously described.23 Depending upon the cell line used, cells were plated at a density of 3000- 6000 cells/well, in a 96 well plate, and 24 h later, drugs were added and serial-diluted. The cells were incubated at 37 °C for 72 h at which time the tetrazolium dye, MTS in combination with phenazine methosulfate, was added. After 3 h, the absorbency was measured at 492 nm, which is proportional to the number of viable cells. The results are expressed as IC50 values.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
