[CAS NO. 1883545-60-5]  CRT0066101 dihydrochloride

CRT0066101 reduces BrdU incorporation, increases apoptosis, blocks neurotensin (NT)-induced PKD1/2 activation, reduces NT-induced PKD-mediated Hsp27 phosphorylation, attenuates PKD1-mediated NF-κB activation, and abrogates expression of NF-κB-dependent-dependent proliferative and pro-survival proteins. CRT0066101 significantly inhibits Panc-1 cell proliferation with an IC50 value of 1 μM. It also significantly reduces cell proliferation of Colo357, Panc-1, MiaPaCa-2, and AsPC-1 cells but has a modest effect in Capan-2 cells. Thus, CRT0066101 significantly blocks proliferation of PaCa cells that express moderate to high endogenous levels of PKD1/2. CRT0066101 (5 µM) blocks both the basal and NT-induced pS916-PKD1/2 (activated PKD1/2) in Panc-1 and Panc-28 cells, also abrogates NT-induced phosphorylation of Hsp27 (pS82-Hsp27), which is a physiological substrate of PKD1/2 in a dose-dependent manner.
