C646是一种histone acetyltransferase(组蛋白乙酰转移酶)抑制剂,抑制p300,Ki为400 nM,比作用于其他乙酰转移酶选择性高。
C646, a pyrazolone-containing small molecule, is a cell-permeable histone acetyltransferase (HAT) inhibitor that competitively and selectively inhibits the HAT activity of p300, a transcriptional co-activator involved in a variety of gene regulatory pathways and protein acetylation events, with the inhibition constant Ki value of 400 nM and the half maximal inhibition concentration IC50 value of 1.6 μM.

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,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
