Antioxidant Activity, Antiproliferative Activity, Antiviral Activity, NO Production Inhibition, and Chemical Composition of Essential Oils and Crude Extracts of Leaves, Flower Buds, and Stems of .

The chemical composition of extracts (CEs) and essential oils (EOs) from leaves, flower buds, and stems was analyzed. Antiproliferative activity against tumor cell lines, NO production inhibition, and antioxidant and antiviral activities were assessed. The CEs contained flavonoids, phenolic acids, coumarins, and saturated fatty acids.

Neutralizing antibodies from naturally infected individuals against SARS-CoV-2 Gamma and Delta variants in the Paraguayan population.

Introduction: Severe Acute Respiratory Syndrome-Coronavirus-2 Virus (SARS-CoV-2) is responsible for Coronavirus Disease 2019 (COVID-19). A substantial number of SARS-CoV-2 infection cases have been reported during the pandemic, and vaccination coverage in some regions, particularly in developing countries, remains very low. SARS-CoV-2 variants of concern (VOCs) have also emerged as some of the most pressing public health issues.

Inhibitory Activity of Extract against Bacteria, Candida, Herpes, and SARS-CoV-2.

Medicinal herbs have long been utilized to treat various diseases or to relieve the symptoms of some ailments for extended periods. The present investigation demonstrates the phytochemical profile, molecular docking, anti- activity, and anti-viral activity of the acetic acid extract. GC-MS analysis of the extract revealed the presence of 69 chemical compounds.

Antiviral activity of two Acanthospermum species against herpes simplex virus 1.

Ethnopharmacological Relevance: Acanthospermum species are used in traditional medicine for treating various pathologies, including bacterial and viral infections. In a screening study, we identified the activity of the ethanolic extracts of Acanthospermum australe and Acanthospermum hispidum against herpes simplex virus 1 (HSV-1).

Aim Of The Study: In this work, we analyzed the phytochemical profile and antiviral activity of the chemical fractionation products of Acanthospermum australe and Acanthospermum hispidum.
