Didemnin B Chemical Properties,Usage,Production

Description

Didemnin B is a cyclic depsipeptide extracted from the Caribbean tunicate Trididemnum cyanophorum. Didemnin B activates caspase, inducing apoptosis and preventing eukaryotic elongation factor 2 (eEF-2)-dependent translocation, inhibiting protein synthesis. This agent also has immunosuppressive and antiviral properties. It is an effective immunosuppressive agent. It is approximately 1,000 times more effective than the standard cyclosporin A. Further study may prove it useful in repressing rejections of transplanted organs[1].

Definition

ChEBI: A natural product found particularly in Lyngbya majuscula and Trididemnum solidum.

Biological Activity

Didemnin B belongs to a group of cyclic depsipeptides produced by Trididemnum solidum Van Name and provides a unique lactylprolin unit in the side chain of the molecule. The natural product interacts with the 80S ribosome, thereby retaining eEF1α in the ribosomal complex despite exhibiting proper GTP hydrolysis. Consequently, eEF2 binding to the ribosome and subsequent eEF2-dependent tRNA translocation are prevented. Didemnin B only shows sufficient binding affinity to the ribosome-eEF1α-complex and not to eEF1α alone. The natural product has antiviral properties and is cytotoxic against both cancerous and normal mammalian cells, whereby highly proliferating cells are more strongly affected than resting cells[2].

in vitro

Didemnin B has activity against miirine B16 melanoma, P388 leukemia, and M5076 sarcoma.

in vivo

Didemnin B is a potent inhibitor of L1210 growth.
