  • Title: Sortase A inhibitory metabolites from the roots of Pulsatilla koreana.
    Author: Lee S, Song IH, Lee JH, Yang WY, Oh KB, Shin J.
    Journal: Bioorg Med Chem Lett; 2014 Jan 01; 24(1):44-8. PubMed ID: 24360605.
    Abstract:
    Three new lignans (3, 4, and 6) along with eight known lignans and phenyl propanoids were isolated from the dried roots of Pulsatilla koreana, an oriental folk medicine. Based upon the results of combined spectroscopic and chemical methods, the structures of new compounds were determined to be lignan glycosides. Included among the known compounds are three compounds (5, 7, and 8) isolated first time from this plant as well as two compounds (2 and 11) previously reported only as synthetic derivatives. These compounds significantly inhibited the action of Sortase A from Streptococcus mutans OMZ65, an isolate from human oral cavity.
