Latin American Plants against Microorganisms.

Area of Science:

• Natural Products Chemistry
• Pharmacology
• Medicinal Botany

Background:

• Emerging health threats like antibacterial resistance and viral pandemics require novel antimicrobial agents.
• Natural products offer a rich source of diverse chemical structures for drug discovery.
• Latin American medicinal plants are a largely untapped resource for identifying bioactive compounds.

Purpose of the Study:

• To review natural products and extracts from Latin America with antimicrobial activity against multidrug-resistant strains.
• To identify classes of plant secondary metabolites with antimicrobial potential.
• To summarize mechanisms of action for plant-derived antimicrobial compounds.

Main Methods:

• Literature review of studies on Latin American medicinal plants and their antimicrobial properties.
• Analysis of secondary metabolites and their structural classes with reported activity.
• Examination of documented mechanisms of action against pathogenic microbes and viruses.

Main Results:

• Identified numerous plant extracts and secondary metabolites from Latin America exhibiting antimicrobial activity.
• Highlighted compounds effective against multidrug-resistant bacteria, fungi, and viruses (e.g., SARS-CoV).
• Discussed various mechanisms of action, including those of specific compounds like aloe-emodin and β-sitosterol.

Conclusions:

• Latin American natural products represent a significant reservoir for novel antimicrobial drug leads.
• Understanding structure-activity relationships is essential for optimizing these natural compounds.
• Continued investigation is vital to combat antimicrobial resistance and emerging infectious diseases.
