How to use

In Vitro:

In the intact platelet, R59022 is able to interrupts thrombin-induced inositol lipid cycling at the level of diacylglycerol and leads to an elevation of protein kinase C activity. R59022 (10 μM) potentiates aggregation, but not shape change induced by sub-maximal concentrations of thrombin. R59022 (10 μM) had no significant effect on the dose-response curve for the mobilization of intracellular Ca2+ by thrombin in either the presence or the absence of extracellular Ca2+. R59022, an inhibitor of filovirus entry, prevents the macropinocytic uptake of filoviral particles, inhibits entry mediated by multiple filovirus GPs, and blocks replicative EBOV growth. R59022 blocks entry of EBOV pseudotypes in a concentration-dependent manner (IC50: ~5 µM). R59022 dose-dependent decreases in entry by the VLPs harboring the EBOV GP (IC50: ~2 µM). R59022 (2-12 μM; 1 hour) can inhibit EBOV GP-mediated entry in multiple cell types. R59022 (5 µM; 30 minutes) blocks macropinocytosis in vero cells.
