The Structure of Hemicalide from the Marine Sponge Hemimycale sp
European Journal of Organic Chemistry, Volume 2022, Issue 25, July 7, 2022., 2022 Hemicalide, isolated from the marine sponge Hemimycale sp., is a very potent cytotoxic compound from a marine sponge with an original mode of action. Its planar structure has been established by NMR and a proposal for 17 of its 21 stereogenic centers is made on the basis of syntheses of analogues.

Microbial Biotechnology, Volume 15, Issue 4, Page 1168-1177, April 2022., 2022 In this study, we identified the diastaphenazine/izumiphenazine C biosynthetic gene cluster through heterologous expression and gene inactivation. The putative biosynthetic pathway of these two compounds was proposed by further functional analysis. Significantly, the polyketide cyclase Dap5 has been proven to be responsible for the dimerization of two ...
