Biochem/physiol Actions

Originally isolated from the marine sponge Thorectandra sp., fascaplysin chloride is a selective, potent inhibitor of cyclin dependent kinase 4/cyclin D1 (IC50 = 0.35 μM). It is significantly less selective for Cdk6/D1 (IC50 = 3.4 μM) and not selective for the other Cdks and tyrosine kinases.

The fascaplysin class of compounds have been further investigated from six organisms consisting of four sponge collections (Fascaplysinopsis reticulata) and two tunicate collections (Didemnum sp.). This work is an extension of an earlier communication and reports the isolation of 12

A new fascaplysin analogue, 3-bromohomofascaplysin A (1), along with two known analogues, homofascaplysin A (2) and fascaplysin (3), were isolated from a Fijian Didemnum sp. ascidian. The absolute configurations of 3-bromohomofascaplysin A (1) and homofascaplysin A (2) were determined via

Novel anti-angiogenesis activity of fascaplysin via VEGF blockage was recently revealed by our previous study in addition to the reported cyclin-dependent kinase 4 (CDK4) selective inhibition. To uncover more details of this pharmacologically prospective property, this study further investigated whether

This study was to evaluate the correlation of two important strategies, namely, cell cycle proliferation arrest and anti-angiogenesis. We chose fascaplysin, a marine natural product with selective CDK4 selective inhibition activity, to study its potential anti-angiogenesis effects in vivo and

Tryptamine derivatives, a new structural class of cyclin dependent kinase 4 inhibitors, have been identified during extensive biological screening of synthetic molecules. The molecules were synthesized based on the structure of fascaplysin, which is not only a specific inhibitor of
