    Description: YM201636, a  pyridofuropyrimidine compound, is a novel, potent and selective PIKfyve (phosphatidylinositol‑3‑phosphate 5‑kinase) inhibitor with potential anti-retroviral replication and anticancer activity,  as silencing of PIKfyve which is the sole enzyme for PtdIns(3,5)P(2) biosynthesis that controls proper endosome dynamics, can inhibit retroviral replication. YM-201636 inhibits PIKfyve with an IC50 of 33 nM. YM 201636 is able to disrupt retroviral budding at 800 nM, indicating its potential usefulness as an antiretroviral therapeutic agent [1,2]. YM201636 may also  inhibit liver tumor growth by promoting EGFR expression [3].

    In Vitro

    In vitro: YM201636 is a selective PIKfyve inhibitor with IC50 of 33 nM, less potent to p110α and insensitive to Fabl (yeast orthologue).


    Kinase Assay: The assay is performed in kinase buffer (25 mM HEPES pH 7.4, 120 mM NaCl, 1.5 mM MgCl2, 5 mM 2-glycerophosphate, and 1 mM DTT) containing 100 μM PI(3)P, GST-PIKfyve, 50 μM ATP/10 μCi [32P]γATP and increasing concentrations of YM201636 in a final volume of 65 μL. The reactions are incubated for 15 minutes at 30 °C, and stopped by the addition of 243 μL of 2:1 MeOH : CHCl3 (volume : volume). Lipid products labelled with 32P are analysed by thin-layer chromatography and quantified by Cerenkov counting. IC50 value is determined by using Graphpad Prism and errors are given as ±95% confidence limit.


    Cell Assay: 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. 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. 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. YM201636 treatment blocks the continuous recycling of junctional proteins claudin-1 and claudin-2 in MDCK cells, leading to the intracellular accumulation and delay of epithelial barrier formation.
