Varacin is a bicyclic organosulfur compound originally found in marine Ascidiacea from the Polycitor genus.[1] It contains an unusual pentathiepin ring which reacts with DNA, and varacin and synthetic analogues have been investigated for their antimicrobial and antitumour properties.[2][3] Because of its potent biological activity and unusual and challenging ring system, it has been a popular target of efforts toward its total synthesis.[4][5][6]
