Antibacterial chromene and chromane stilbenoids from Hymenocardia acida

Phytochemistry. 2014 Feb:98:216-22. doi: 10.1016/j.phytochem.2013.11.012. Epub 2013 Dec 19.

Abstract

Six chromene stilbenoids and one chromane stilbenoid were isolated from the African tree Hymenocardia acida. Several were moderately active against methicillin-resistant Staphylococcus aureus clinical isolate MRSA-108, including hymenocardichromanic acid, which was active at 8 μg/ml. None had IC50 values <20 μM in antiproliferation assays against several human cancer cell lines.

Keywords: Chromane; Chromene; Hymenocardia acida; Methicillin-resistant Staphylococcus aureus (MRSA); Phyllanthaceae.
