Description: Plitidepsin is a cyclic depsipeptide isolated from the marine tunicate Aplidium albicans. Plitidepsin displays a broad spectrum of antitumor activities, inducing apoptosis by triggering mitochondrial cytochrome c release, initiating the Fas/DC95, JNK pathway and activating caspase 3 activation. This agent also inhibits elongation factor 1-a, thereby interfering with protein synthesis, and induces G1 arrest and G2 blockade, thereby inhibiting tumor cell growth.

Additional Information

Plitidepsin (also known as dehydrodidemnin B, marketed by PharmaMar, S.A. under the trade name Aplidin) is a chemical compound extracted from the ascidian Aplidium albicans. It is currently undergoing clinical trial testing. It is a member of the class of compounds known as didemnins.

plitidepsin exhibits antitumor, antiviral and immunosuppressive activities. It shows promise in shrinking tumors in pancreatic, stomach, bladder, and prostate cancers. As of 2007, it was undergoing multicenter phase II clinical trials, In July 2003, plitidepsin was granted orphan drug status by the European Medicines Agency for treating acute lymphoblastic leukemia.
