Biological effects of Avicennia marina (Forssk.) vierh. extracts on physiological, biochemical, and antimicrobial activities against three challenging mosquito vectors and microbial pathogens. Environ Sci Pollut Res Int. 2020 Feb 18;: Authors: Karthi S, Vinothkumar M, Karthic U, Manigandan V, Saravanan R, Vasantha-Srinivasan P, Kamaraj C, Shivakumar MS, De Mandal S, Velusamy A, Krutmuang P, Senthil-Nathan S Abstract Mosquitoes are principal vector of several vector-borne diseases affecting human beings leading to thousands of deaths per year and responsible for transmitting diseases like malaria, dengue, chikungunya, yellow fever, Zika virus, Japanese encephalitis, and lymphatic filariasis. In the present study, we evaluated the different solvent extracts of mangrove Avicennia marina for their toxicity against larvae of three major mosquito vectors, as well as selected microbial pathogens. The larvicidal mortality of third instars was observed after 24 h. Highest larval mortality was found for the acetone extract of A. marina against Culex quinquefasciatus (LC50 = 0.197 mg/ml; LC90 = 1.5011 mg/ml), Anopheles stephensi (LC50 = 0.176 mg/ml; LC90 = 3.6290 mg/ml), and Aedes aegypti (LC50 = 0.164 mg/ml; LC90 = 4.3554 mg/ml). GC-MS analysis of acetone extract revealed 5 peaks, i.e., 1-hexyl-2-nitrocyclohexane (3.229%), eicosanoic acid (40.582%...

Conclusion: CoBaT-Y017, a Phase II study was conducted with Plasmodium falciparum malaria-infected patients, for efficacy and safety evaluation of CoBaT-Y017 compared with Artemether-Lumefantrine used as a positive control. Methods. A single-blind randomized trial was conducted on 25 eligible males aged 18-40 years randomly assigned to two treatment groups: CoBaT-Y017 or Artemether-Lumefantrine. The first group received 35 ml of CoBaT-Y017 in 1.5 L mineral water administered daily for four consecutive days; the second group received oral Artemether-Lumefantrine, using WHO-recommended therapeutic dose regimens...
