Product Description
Selective inhibitor of phosphatidylcholine-specific phospholipase C. Has been used to study the coupling of phosphatidylcholine-specific phospholipase C with sphingomyelinase. Shows antitumor and antiviral activity. Inhibits basement membrane collagen synthesis, which is the last step in the development of a new blood vessel. Inhibits induction of nitric oxide synthases (NOS). Induces apoptosis.
