Abstract
During genome mining for thioviridamide-like biosynthetic gene clusters that could produce polythioamide RiPP (ribosomally synthesized and post-translationally modified peptides), we discovered a novel cryptic biosynthetic gene cluster. During efforts to express this biosynthetic gene using heterologous expression of this biosynthetic gene cluster, a novel compound designated as neothioviridamide was produced. We report herein the cloning and heterologous expression of the neothioviridamide biosynthetic gene cluster and the isolation, structure determination, and cytotoxic activity of neothioviridamide.
