生物活性
GSK3368715 2HCl is a novel potent, orally active, reversible type I protein arginine methyltransferases (PRMTs) inhibitor, with IC50 values of 3.1 nM, 48 nM, 1148 nM, 5.7 nM and 1.7 nM for PRMT1, PRMT3, PRMT4, PRMT6, PRMT8, respectively. GSK3368715 induces anti-proliferative effects on cell lines from a broad range of hematological and solid tumor types in vitro. In vivo, GSK3368715 has potent, anti-proliferative activity across cell lines representing a range of solid and hematological malignancies and can completely inhibit tumor growth or cause regressions of tumor models. GSK3368715 dihydrochloride (EPZ019997 dihydrochloride) significantly effects on the growth of BxPC3 xenografts at all doses tested, reducing tumor growth by 78% and 97% in the 150- and 300-mg/kg dose groups, respectively.

细胞系 | Toledo cells, BxPC3 cells, MiaPaca-2 cells, ACHN cells, MDA-MB-468 cells, RKO cells, Panc03.27 cells, etc. |
方法 | RKO cells are seeded in a clear bottom 384 well plates andtreated with a 20-point two-fold dilution series of GSK3368715 (29,325.5 to 0.03 nM) or 0.15% DMSO. Plates are incubated for 3 days at 37℃ in 5% CO2. Cells are fixed with ice-cold methanol for 30 minutes at room temperature, washed with phosphate buffered saline (PBS), then incubated with Odyssey blocking buffer (Licor) for 1 hour at room temperature. |

重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B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。
