Description: CID-755673 is a selective protein kinase D (PKD) inhibitor. CID-755673 was identified from the National Institutes of Health small molecule repository library of 196,173 compounds. In cell-based assays, CID755673 blocked phorbol ester-induced endogenous PKD1 activation in LNCaP cells in a concentration-dependent manner. CID755673 inhibited prostate cancer cell proliferation, cell migration, and invasion. In summary, our findings indicate that CID755673 is a potent and selective PKD1 inhibitor with valuable pharmacological and cell biological potential.
