- Vosamidines A-C, Polycyclic 2-Aminoimidazole Alkaloids from a Marine Calcareous Sponge . Senadeera, Sarath P D Wang, Dongdong Wilson, Brice A P Smith, Emily A Leal, Camille V Zhang, Ping O'Keefe, Barry R Carroll, Anthony R Beutler, John A Porifera Alkaloids Animals Imidazoles Molecular Structure Vosamidines A-C (-), three polycyclic 2-aminoimidazole alkaloids, were isolated from a marine calcareous sponge, . Their structures were determined by extensive analysis of spectroscopic and spectrometric data, along with ECD computational studies. Vosamidine A possesses a 6/5/5/5/6/15(6)(5)-fused ring system based on a unique pentacyclic core. Vosamidine B is an oxidized and ring rearranged derivative of . Vosamidine C possesses an unusual 5/5/6/5/5/8 hexacyclic ring system incorporating a thioether ring. Plausible biosynthetic pathways for - are proposed. Compounds and had modest inhibition in the oncogenic fusion protein kinase DNAJB1-PKAcα assay.
