MW: 217.22. Purity ≥98% by HPLC. Background: CID-755673 is a selective small molecule inhibitor of protein kinase D (PKD) (IC??s = 182, 280, 227 nM for PKD1, 2, and 3, respectively). It exhibits higher selectivity for PKD over Akt, polo-like kinase 1, CDK activating kinase, CAMKII and three different PKC isoforms (IC??s range from 15 to > 50 uM). At 25 uM, CID-755673 has been shown to inhibit prostate cancer cell proliferation, cell migration, and invasion.
