D609 is a selective inhibitor of phosphatidylcholine-specific PLC (PC-PLC). D609 has been employed to establish the functional coupling of PC-PLC with sphingomyelinase and to establish the coupling of PC hydrolysis to the activation of Raf-1 protein kinase. A recent report showed that D609 indirectly inhibits phorbol ester-stimulated PLD activity. D609 possesses antitumor and antiviral activity. D609 also inhibits hypoxia-induced HIF-1α expression via blocking the biosynthesis of phosphatidic acid. D609 has provided benefits after stoke through induction of cell-cycle arrest by up-regulating p21, inhibition of SMS, causing hypophosphorylation of Rb and increased ceramide levels. D609 is a colorless, crystalline solid utilized in various scientific research applications. It possesses a melting point of 198-200°C and a boiling point of 254°C. Its precise mechanism of action remains partially unknown, but it is believed to function as a chelating agent, binding to metal ions in the body and modifying their activity. Moreover, it is considered an antioxidant that combats free radicals and guards against oxidative harm.

Is this compound cell permeable? Do we have any information about what concentration it should be used at?

Asked by: Jz28sail
Thank you for your question. sc-201403, D609 is not cell permeable. D609 has been shown to selectively inhibit phosphatidylcholine (PC)-specific phospholipase C at a 5 - 10 µM concentration.
