Tool name: Protein Kinase D inhibitor CRT0066101 Small Molecule (Tool Compound)
Molecular formula: C18H23CIN6
Tool type: Small molecules
Tool sub-type: Inhibitor
Molecular weight of the target: 374.86776
Application: In Panc-1 subcutaneous xenograft model, orally administration of CRT0066101 at the dosage of 80 mg/kg/d for 24 days significantly suppressed pancreatic cancer growth. Moreover, when CRT0066101 reached its peak concentration (12 Îźmol/L) in tumor model, the expression of activated PKD1/2 in the treated tumor explants was substantially decreased. It was concluded that CRT0066101 given orally at 80 mg/kg/d for 21 days in Panc-1 orthotropic model suppressed tumor growth potently in vivo.
Clinical trial: So far, no clinical trial has been conducted. In Panc-1 cell line based assays, CRT0066101 was reported to reduce bromodeoxyuridine incorporation; increase cell apoptosis; suppress neurotensin-induced PKD1/2 activation; block neurotensin-induced Hsp27 phosphorylation; interrupt PKD1-mediated NF-ÎşB activation as well as down-regulate expression of NF-ÎşB-dependent proliferative and pro-survival proteins.
Description: The Protein Kinase D inhibitor CRT0066101 is a potent antitumoral agent in vitro and in vivo. Protein kinase D (PKD) is an evolutionarily conserved protein kinase family with structural, enzymological, and regulatory properties different from the PKC family members. Signaling through PKD is induced by a remarkable number of stimuli, including G-protein-coupled receptor agonists and polypeptide growth factors. PKD1, the most studied member of the family, is increasingly implicated in the regulation of a complex array of fundamental biological processes, including signal transduction, cell proliferation and differentiation, membrane trafficking, secretion, immune regulation, cardiac hypertrophy and contraction, angiogenesis, and cancer. PKD mediates such a diverse array of normal and abnormal biological functions via dynamic changes in its spatial and temporal localization, combined with its distinct substrate specificity. Studies on PKD thus far indicate a striking diversity of both its signal generation and distribution and its potential for complex regulatory interactions with multiple downstream pathways, often regulating the subcellular localization of its targets.
Research area: Cancer; Cell Signaling & Signal Transduction; DNA Damage and Repair
Selectivity: Selectivity for PKD against a panel of >90 protein kinases, including PKCÎą, MEK, ERK, c-Raf and c-Src.
IUPAC: 2-[4-((R)-2-Amino-butylamino)-pyrimidin-2-yl]-4-(1-methyl-1Hpyrazol-4-yl)-phenol; hydrochloride
IC50: IC50 1, 2 and 2.5 nM for PKD1, PKD3 and PKD2 respectively
Additional notes: Using Panc-1 as a model system, it has been demonstrated that CRT0066101:
â˘ Reduced bromodeoxyuridine incorporation
â˘ Increased apoptosis
â˘ Blocked neurotensin-induced PKD1/2 activation
â˘ Reduced neurotensin-induced, PKD-mediated Hsp27 phosphorylation
â˘ Attenuated PKD1-mediated NF-ÎşB activation
â˘ Abrogated the expression of NF-ÎşB-dependent proliferative and pro-survival proteins
