Biological Activity

Description CRT0066101 dihydrochloride is a small molecule PKD family specific inhibitor which specifically blocks PKD1/2 activity and does not suppress PKCα/PKCβ/PKCε activity in multiple.
Targets
PKD1 [1]
(Cell-free assay)		 PKD3 [1]
(Cell-free assay)		 PKD2 [1]
(Cell-free assay)
1 nM 2 nM 2.5 nM
In vitro

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[1].
In vivo

CRT0066101 given orally (80 mg/kg/day) for 28 days significantly abrogates PaCa growth in Panc-1 subcutaneous xenograft model. Activated PKD1/2 expression in the treated tumor-explants is significantly inhibited with peak tumor concentration (12 µM) of CRT0066101 achieved within 2 h after oral administration. CRT0066101 given orally (80 mg/kg/day) for 21 days in Panc-1 orthotopic model potently blocks tumor growth in vivo. CRT0066101 significantly reduces Ki-67+ proliferation index (p< 0.01), increases TUNEL+ apoptotic cells (p<0.05), and abrogates expression of NF-κB-dependent proteins including cyclin D1, survivin, and cIAP-1. CRT0066101 blocks Panc-1 cell proliferation and growth in multiple xenograft models[1]
