TWS119是一种GSK-3β抑制剂,IC50为30 nM;能够诱导神经细胞的分化,有助于干细胞生物学的研究。
TWS119 is screened out from a library of pyrrolopyrimidines as a molecule that selectively induces neuronal differentiation when using mouse P19 EC cells. TWS119 binds to GSK-3β tightly with a Kd value of 126nM and shows an inhibition with IC50 value of 30nM. The combination of TWS119 and GSK-3β modulates the activity of the complex and triggers downstream transcriptional events lead the neuronal induction. Besides that, TWS119 promotes neuronal differentiation of mESCs through another mechanism but not the canonical Wnt signaling pathway.

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。
