Description:	R 59-022 (DKGI-I) is a diacylglycerol kinase inhibitor (IC50=2.8 μM). R 59-022 is a 5-HTR antagonist, and activates protein kinase C (PKC). R 59-022 potentiates thrombin-induced diacylglycerol production in platelets and inhibits phosphatidic acid production in neutrophils[1][2][3][4].
In Vitro:	In the intact platelet, R 59-022 is able to interrupts thrombin-induced inositol lipid cycling at the level of diacylglycerol and leads to an elevation of protein kinase C activity[1]. R 59-022 (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+[2]. R 59-022, an inhibitor of filovirus entry, prevents the macropinocytic uptake of filoviral particles, inhibits entry mediated by multiple filovirus GPs, and blocks replicative EBOV growth. R 59-022 blocks entry of EBOV pseudotypes in a concentration-dependent manner (IC50: ~5 µM). R 59-022 dose-dependent decreases in entry by the VLPs harboring the EBOV GP (IC50: ~2 µM). R 59-022 (2-12 μM; 1 hour) can inhibit EBOV GP-mediated entry in multiple cell types. R 59-022 (5 µM; 30 minutes) blocks macropinocytosis in vero cells[5].
