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.

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

Various aspects of the physiological activity of fascaplysine, a pigment from tropic sea sponges, were studied. One of the fragments of the chemical structure of the pigment is the indole ring. Ehrlich tumor cells, murine lymphocytes and erythrocytes were used

Cyclin-dependent kinases (CDKs) successively phosphorylate the retinoblastoma protein (RB) at the restriction point in G1 phase. Hyperphosphorylation results in functional inactivation of RB, activation of the E2F transcriptional program, and entry of cells into S phase. RB unphosphorylated at serine
