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.
