title: Varacin and three new marine antimicrobial polysulfides from the far-eastern ascidian Polycitor sp.
abstract: Varacin [1] and three new antimicrobial marine polysulfides, varacins A-C [3-5], have been isolated from the Far Eastern ascidian Polycitor sp. Their structures have been elucidated by spectroscopic methods and by chemical transformations.
