YM-201636的生物活性
YM201636 is a selective PIKfyve inhibitor with IC50 of 33 nM, less potent to p110α.
IC50 value: 33 nM [1]
Target: PIKfyve
in vitro: YM201636 potently inhibits mammalian PIKfyve with an IC50 of 33 nM but not yeast orthologue Fab1 with an IC50 of >5 μM, exhibiting around 100-fold selectivity for PtdIns3P p110α with an IC50 of 3 μM. YM201636 (0.8 μM) significantly decreases the production of PtdIns(3,5)P2 by 80% in serum-starved NIH3T3 cells followed by serum stimulation with no effect on serum-stimulated protein kinase B (PKB) Ser 473 phosphorylation. YM-201636 reversibly impairs endosomal trafficking in NIH3T3 cells by blocking PIKfyve and PtdIns(3,5)P2 production, mimicking the effect produced by depleting PIKfyve with siRNA. YM-201636 (0.8 μM) also significantly reduces retroviruses budding from cells by 80%, apparently through interfering with the endosomal sorting complex required for transport (ESCRT) machinery [1]. In 3T3L1 adipocytes, YM-201636 inhibits basal and insulin-activated 2-deoxyglucose uptake with an IC50 of 54 nM, with almost complete inhibition at doses as low as 160 nM. YM-201636 (0.1 μM) has also been shown to completely block insulin-dependent activation of class IA PI 3-kinase [2]. Although not involved in NPM-ALK-dependent proliferation and migration, YM201636 (0.4 μM) strongly reduces invasive capacities of NPM-ALK-expressing cells and their capacity to degrade the extracellular matrix [3].
