Resumo:To evaluate the phenolic profile and biological activity of the Algerian Sahara plant Acacia tortilis (Forssk.) Hayne ssp. raddiana decoction and 80% ethanolic extracts were studied. Chromatographic profiling indicated the presence of 36 phenolic compounds, including gallic acid esterified derivatives, galloylquinic derivatives and flavan-3-ols galloyl derivatives. Both extracts showed significant cytotoxic activity and a potent anti-inflammatory activity. They were effective against several multi-drug resistant bacteria, namely methicillin-resistant Staphylococcus aureus (MRSA). To understand the possible mechanism of action of MRSA inhibition activity, an in silico docking analysis was done using a virtual library of the 36 determined phenolic compounds against penicillin-binding protein (PBP2a), a protein known to be involved in MRSA resistance to β-lactam antibiotics. A. tortilis extracts showed interesting biological activities and the phenolic compounds found could be an interesting starting point for the development of cytotoxic and anti-inflammatory drugs and especially anti-MRSA antibiotics.
