YM-201636 is an inhibitor of retroviral budding and PIKfyve-catalyzed PtdIns(3,5)P2 synthesis, and can also halt glucose entry by insulin in adipocytes. YM-201636 almost completely inhibited basal and insulin-activated 2-deoxyglucose uptake at doses as low as 160 nM, with IC(50)=54+/-4 nM for the net insulin response. Insulin-induced GLUT4 translocation was partially inhibited at substantially higher doses, comparable to those required for inhibition of insulin-induced phosphorylation of Akt/PKB. In addition to PIKfyve, YM-201636 also completely inhibited insulin-dependent activation of class IA PI 3-kinase.

Acute treatment of cells with YM-201636 shows that the PIKfyve pathway is involved in the sorting of endosomal transport, with inhibition leading to the accumulation of a late endosomal compartment and blockade of retroviral exit. The yeast orthologue of PIKfyve, Fab1, is found to be insensitive to YM-201636 (IC50>5 μM). YM-201636 does not inhibit a type IIγ PtdInsP kinase even at 10 μM and inhibits a mouse type Iα PtdInsP kinase with an IC50>2 μM.
YM-201636 almost completely inhibits basal and insulin-activated 2-deoxyglucose uptake at doses as low as 160 nM, with IC50=54 nM for the net insulin response. YM-201636 also completely inhibits insulin-dependent activation of class IA PI 3-kinase. At low doses (10-25 nM), YM-201636 inhibits preferentially PtdIns5P rather than PtdIns(3,5)P2 production, whereas at higher doses, the two products are similarly inhibited.
YM-201636 at 160 nM inhibits PtdIns5P synthesis twice more effectively compared with PtdIns(3,5)P2 synthesis. MDCK cells treated with YM-201636 accumulate the tight junction protein claudin-1 intracellularly.
YM-201636 treatment blocks the continuous recycling of claudin-1/claudin-2 and delays epithelial barrier formation.
