In Vitro Evaluation of the Antimicrobial Ability and Cytotoxicity on Two Melanoma Cell Lines of a Benzylamide Derivative of Maslinic Acid

الملخص EN

Maslinic acid is a pentacyclic triterpene extracted from olives that has been systematically reported to exert several therapeutic effects, such as antitumoral, antidiabetic, antioxidant, anti-inflammatory, antiparasitic, and antiviral properties.

Recently, new derivatives of maslinic acid have been obtained and expanded the spectrum of biological activities and improved the existing ones.

The present study was meant to perform the in vitro assessment of the (i) cytotoxic effects of a benzylamide derivative of maslinic acid (“EM2”) (benzyl (2α, 3β) 2,3-diacetoxy-olean-12-en-28-amide) on B164A5 murine melanoma and A375 human malignant melanoma cell lines and the (ii) antimicrobial activity of the compound on several bacterial strains, respectively.

We obtained a dose-dependent cytotoxic effect of EM2 that was particularly relevant to the murine cell line.

As on the antibacterial activity, EM2 was tested on 10 bacterial strains Bacillus cereus, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Enterococcus faecalis, Escherichia coli, Yersinia enterocolitica, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa and one fungus Candida albicans.

A significant antimicrobial effect was recorded for Streptococcus pyogenes and Staphylococcus aureus.
