kb NB 142-70 (1233533-04-4) Description

kb NB 142-70 is a selective protein kinase D (PKD) inhibitor (IC50 values are 28.3, 58.7 and 53.2 nM for PKD1, 2 and 3 respectively).kb NB 142-70 is a selective protein kinase D (PKD) inhibitor with IC50 values are 28.3, 58.7 and 53.2 nM for PKD1, 2 and 3 respectively. kb NB 142-70 prevents wound-induced migration of intestinal epithelial cells. PKD1, the most studied member of the PKD family, is implicated in the regulation of a remarkable array of fundamental biological processes, including signal transduction, cell proliferation and differentiation, membrane trafficking, hormone secretion, immune regulation, cardiac hypertrophy, angiogenesis, and cancer.
