PS315 inhibits the full-length and catalytic domain constructs of PKCζ (IC50=10 μM) and PKCη (IC50=30 μM). PS315 has anti-cancer activity. PS315 is a derivative of PS48 and is an allosteric PKC inhibitor by binding to the PIF-pocket of aPKC and inducing d
Protein kinase C (PKC ) is a calcium-independent, phospholipid- and diacylglycerol-dependent serine/threonine kinase involved in diverse signaling pathways, including those involved in neuronal signaling, cytoskeletal function, and inflammation.[1] PKC inhibitor peptide is a synthetic peptide corresponding to an amino acid sequence found in the amino terminal C2 domain of most mammalian forms of PKC .[2] It selectively and reversibly inhibits the translocation of PKC to intracellular membranes, blocking activation.[2] PKC inhibitor peptide is commonly used in cells to evaluate the role of PKC in various cellular responses.[3],[4],[5]
PKC-IN-4 (compound 7l) is a highly potent and orally active inhibitor of atypical protein kinase C (aPKC), exhibiting an IC 50 value of 0.52 μM. In vitro studies have demonstrated that PKC-IN-4 effectively suppresses NF-κB activity induced by TNF-α. Moreover, this compound effectively impedes the permeability of the retinal vasculature, induced by both VEGF and TNFα. [1]
