RK-682
RK-682 is the inhibitor for protein tyrosine phosphatase (PTPase), heparanase, phospholipase A2 and HIV-1 protease. RK-682 inhibits the dephosphorylation of CD45 (IC50 is 54 μM) and VHR (IC50 is 2.0 μM), and thereby inhibits the ERK signaling pathway. RK-682 inhibits the cell viability of cancer cell MGH-U3, T24 and UROtsa with IC50s of 78.2, 43.2 and 145 nM, respectively, arrests the cell cycle at G1/S phase, inhibits the cell migration and autophagy in MGH-U3 and T24.
