Tn. Makarieva et al., VARACIN AND 3 NEW MARINE ANTIMICROBIAL POLYSULFIDES FROM THE FAR-EASTERN ASCIDIAN POLYCITOR SP, Journal of natural products, 58(2), 1995, pp. 254-258
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.
