|Description||CRT0066101 is a small molecule PKD family specific inhibitor which specifically blocks PKD1/2 activity and does not suppress PKCα/PKCβ/PKCε activity in multiple.|
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.
|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|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
