RK-682 is a novel tyrosine phosphatase inhibitor isolated from Streptomyces sp. It inhibits the dual specificity VHR phosphatase (IC50=2.0µM) selectively over CD45 (IC50=54µM), Cdc25B and PTP1B (IC50~42µM). RK-682 inhibits cell cycle progression of Ball-1 cells at the G1/S transition and enhances ATP-induced long-term potentiation in guinea pig hippocampal CA1 neurons. Shows potent activity against HIV-1 protease.
