Abstract

Background: Tontelea micrantha, a notable plant species, has garnered interest for its medicinal properties, including anti-inflammatory, antibacterial and antiviral effects. A vaccine for Chikungunia virus is still under evaluation and no specific antiviral drug has been licensed to date.

Objective: The work investigated antiviral activity of ethyl acetate (EAEF) and methanolic (EMF) extracts from T. micrantha leaves in mammalian cells exposed to Alphavirus chikungunya (CHIKV). This plant species showed remarkable medicinal properties including anti-inflammatory, antiviral and antibacterial effects.

Methods: The cytotoxicity, antiviral activity, selectivity index, effect on viral gene expression, virus production, and mechanisms of action were evaluated.

Results: EAEF and EMF extracts showed anti-CHIKV effects at non-cytotoxic concentrations, with CC₅₀ above 300μg/mL, EC₅₀ of 18 and 43 μg/mL respectively, and selectivity Index above 4. These concentrations drastically reduce viral yields and CHIKV gene expression and have shown activity both directly on viral particles and at different stages of the viral cycle.

Conclusion: EAEF and EMF showed robust antiviral activity against CHIKV, making them promising candidates for the development of anti-CHIKV drugs.

期刊介绍： The aim of Drug Development and Industrial Pharmacy is to publish novel, original, peer-reviewed research manuscripts within relevant topics and research methods related to pharmaceutical research and development, and industrial pharmacy. Research papers must be hypothesis driven and emphasize innovative breakthrough topics in pharmaceutics and drug delivery. The journal will also consider timely critical review papers.
