Sortase A inhibitory metabolites from the roots of Pulsatilla koreana

Bioorg Med Chem Lett. 2014 Jan 1;24(1):44-8. doi: 10.1016/j.bmcl.2013.12.006. Epub 2013 Dec 8.

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.

Keywords: Lignans; Phenyl propanoid; Pulsatilla koreana; Sortase A.
