Abstract
Anti-Trypanosoma cruzi activity of compounds from fruits of Schinus terebinthifolius Raddi (pink pepper) were evaluated, using sustainable techniques such as steam distillation (SD) and supercritical fluid extraction (SFE). SD was optimised using a design of experiment and SFE was carried out using supercritical CO2 solvent (300 bar and 60 °C). Results of the anti-T. cruzi activity showed that the essential oil presented high activity (IC50 = 4.5 ± 0.3 μg/mL), whereas the supercritical extract had a moderate effect (IC50 = 19.7 ± 2.9 μg/mL). The differences in the anti-T. cruzi activity can be attributed to the extraction of non-volatile compounds in the SFE, such as moronic and (Z)-masticadienoic acids. In contrast, SD extracted only volatile compounds such as monoterpenes and sesquiterpenes. Therefore, these results suggest that the volatile compounds from pink pepper are involved with the anti-T. cruzi activity.

Robust Antiviral Activity of Santonica Flower Extract ( Artemisia cina) against Avian and Human Influenza A Viruses: In Vitro and Chemoinformatic Studies. ACS OMEGA 2022; 7:41212-41223. [PMID: 36406485 PMCID: PMC9670689 DOI: 10.1021/acsomega.2c04867] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 10/20/2022] [Indexed: 05/25/2023]
Abstract
The evolution of drug-resistant viral strains following natural acquisition of resistance mutations is a major obstacle to antiviral therapy. Besides the improper prescription of the currently licensed anti-influenza medications, M2-blockers and neuraminidase inhibitors, to control poultry outbreaks/infections potentiates the emergence of drug-resistant influenza variants. Therefore, there is always a necessity to find out new alternatives with potent activity and high safety. Plant extracts and plant-based chemicals represent a historical antiviral resource with remarkable safety in vitro and in vivo to control the emerging and remerging health threats caused by viral infections. Herein, a panel of purified plant extracts and subsequent plant-derived chemicals were evaluated for their anti-avian influenza activity against zoonotic highly pathogenic influenza A/H5N1 virus. Interestingly, santonica flower extract (Artemisia cina) showed the most promising anti-H5N1 activity with a highly safe half-maximal cytotoxic concentration 50 (CC50 > 10 mg/mL) and inhibitory concentration 50 (IC50 of 3.42 μg/mL). To confirm the anti-influenza activity, we assessed the anti-influenza activity of the selected plant extracts against seasonal human influenza A/H1N1 virus and we found that santonica flower extract showed a robust anti-influenza activity that was comparable to the activity against influenza A/H5N1. Furthermore, the mode of action for santonica flower extract with strong inhibitory activity on the abovementioned influenza strains was elucidated, showing a virucidal effect. To go deeper about the activity of the chemometric component of the extract, the major constituent, santonin, was further selected for in vitro screening against influenza A/H5N1 (IC50 = 1.701 μg/mL) and influenza A/H1N1 (IC50 = 2.91 μg/mL). The oxygen of carbonyl functionality in the cyclohexene ring succeeded to form a hydrogen bond with the neuraminidase active site. Despite the fact that santonin revealed similarity to both reference neuraminidase inhibitors in forming hydrogen bonds with essential amino acids, it illustrated shape alignment to oseltamivir more than zanamivir according to Tanimoto algorithms. This study highlights the applicability of santonica flower extract as a promising natural antiviral against low and highly pathogenic influenza A viruses.

Abstract
Mayaro virus is an emerging arbovirus that causes nonspecific febrile illness or arthralgia syndromes similar to the Chikungunya virus, a virus closely related from the Togaviridae family. MAYV outbreaks occur more frequently in the northern and central-western states of Brazil; however, in recent years, virus circulation has been spreading to other regions. Due to the undifferentiated initial clinical symptoms between MAYV and other endemic pathogenic arboviruses with geographic overlapping, identification of patients infected by MAYV might be underreported. Additionally, the lack of specific prophylactic approaches or antiviral drugs limits the pharmacological management of patients to treat symptoms like pain and inflammation, as is the case with most pathogenic alphaviruses. In this context, this review aims to present the state-of-the-art regarding the screening and development of compounds/molecules which may present anti-MAYV activity and infection inhibition.
