Compounds 20(S)-protopanaxadiol (PPD), 3, 5, 16 and 24 exhibited potent antibacterial activity against Gram-positive bacteria. Compounds 3 and 5 also displayed promising antibacterial activity against a community associated methicillin-resistant Staphylococcus aureus (CA-MRSA; strain USA300). Furthermore, compounds PPD, 3 and 16 combined with two commercially available antibiotics kanamycin and chloramphenicol showed strong synergistic inhibitory effects at their sub-MIC concentrations against S. aureus USA300 and Bacillus subtilis 168. Additionally, cytotoxic activity assay showed that the compounds tested did not affect cell viability of the human epithelial kidney (HEK-293) and human cervical (HeLa) cells at their MICs.]]> Sat 24 Mar 2018 07:52:12 AEDT ]]>
