PKC Activators

Ingenol 3-angelate (CAS 75567-37-2) is a diterpene ester compound known for its ability to activate Protein Kinase C (PKC). It binds to the C1 domain of PKC, similar to diacylglycerol (DAG) and phorbol esters, facilitating the translocation of the enzyme to the cell membrane. Once at the membrane, PKC becomes active and participates in various intracellular signaling processes. The compound is often used in research to study PKC-mediated pathways.

DCP-LA (CAS 28399-31-7), or 8-(2-(2-Pentyl-cyclopropylmethyl)-cyclopropyl)-octanoic acid, is a synthetic fatty acid derivative known to activate Protein Kinase C (PKC). It works by binding to specific PKC isoforms, leading to their activation.

Phosphatidylinositol 4,5-bisphosphate (PIP2) is a cell membrane phospholipid. It's hydrolyzed to produce diacylglycerol (DAG), which directly activates Protein Kinase C (PKC) by binding to its C1 domain. Therefore, PIP2 acts as an indirect PKC activator by being a DAG precursor, facilitating PKC activation in cellular signaling.
