Online ahead of print.ABSTRACTThe number of human infections with multidrug-resistant (MDR) bacteria is increasing worldwide and constitutes a serious threat to human health. Given the lack of novel antibiotic compounds worsening this dilemma, alternative antibiotic-independent treatment and prevention strategies of infectious diseases applying natural compounds appear highly appreciable. Given the long-known health-beneficial and disease-alleviating properties of Cannabis, we performed a literature search summarizing current knowledge regarding the antibacterial effects of extracts from different parts of the Cannabis sativa plant and of defined Cannabis-derived molecules and their potential mode of action. The included studies revealed that various extracts and essential oils of C. sativa as well as major cannabinoids exerted potent activities against a broad spectrum of Gram-positive bacteria and against some Gram-negative bacterial species including MDR strains. Particularly the disruption of the bacterial cytoplasmic membrane by some cannabinoids resulted in potent antibacterial effects against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus. Furthermore, defined cannabinoids inhibited the formation of and eradicated existing bacterial biofilms. In conclusion, given their antibacterial properties distinct Cannabis-derived molecules expand the repertoire of antibiotics-independent treatment options in the combat of bacterial infectious diseases which should be further addressed in future studies including clinical trials.PMID:39470741 | DOI:10.1556/1886.2024.00098
