Kulokekahilide-2, a Cytotoxic Depsipeptide from a Cephalaspidean Mollusk Philinopsis speciosa
摘要:
A cytotoxic depsipeptide, kulokekahilide-2 (1), was isolated from a cephalaspidean mollusk, Philinopsis speciosa. The structure elucidation of kulokekahilide-2 was carried out by spectroscopic analysis and chemical degradation. Kulokekahilide-2 showed potent cytotoxicity against several cell lines (P388, SKOV-3, MDA-MB-435, and A-10 with IC50 values ranging from 4.2 to 59.1 nM) indicating cancer cell selectivity.
Provided are cyclic peptide analogs, conjugates comprising such compounds, and pharmaceutical compositions comprising such compounds and conjugates, and methods of treating cancer with such compounds and conjugates.
