U-73343

U-73122 (Cay-70740) is an inhibitor of PLC-dependent processes, however, the mechanism of action remains unclear. The IC50 values for inhibition of platelet aggregation induced by collagen or thrombin are 0.6 and 5 µM, respectively. It also exhibits inhibitory activity against HIV-1 integrase with an IC50 value of 7 µM. U-73343 is a close structural analog of U-73122 that does not inhibit PLC, making it useful as a negative control for PLC inhibition.Formal Name: 1-[6-[[(17b)-3-methoxyestra-1,3,5(10)-trien-17-yl]amino]hexyl]-2,5-pyrrolidinedione.
