Description
Indolactam V (-) (90365-57-4) is a PKC activator acting at the phorbol ester binding site.1,2?Directs differentiation of human and mouse ESCs to pancreatic cells.3?? May be used, along with other agents, to differentiate human iPS cells into glucose-responsive insulin-secreting progeny.4?Increases regulator of G protein signaling 2 (RGS2) protein levels, a protein that regulates GPCR signaling.5
Uses
(-)-Indolactam V is an indole alkaloid compound which activates protein kinase C (PKC). Weak tumor promoter. Also directs differentiation of human embryonic stem cells, potentially into pancreatic lineage allowing for an effective diabetes therapy.
Definition
ChEBI: (-)-indolactam V is a 9-membered ring that is a potent protein kinase C activator
Biological Activity
Protein kinase C activator. Exhibits tumor promoting activity. Directs differentiation of human embryonic stem cells (ESCs) into pancreatic progenitors.
Biochem/physiol Actions
(-)-Indolactam V is a PKC activator shown to effect differentiation in embryonic stem cells leading to development of pancreatic precursors. It is active in the mouse model.
storage
Desiccate at -20°C
