Researchers assessed 11 plants from Santarém City in the Brazilian Amazonia for their antimalarial properties. Acmella oleracea, Siparuna krukovii, and Trema micrantha showed the highest inhibition of parasite growth. The ethanol extract of A. oleracea flowers holds promise for developing antimalarial phytomedicine.
A study investigated the anticancer activity of jambu, a plant found in the Brazilian Amazon. The hydroethanolic extract of jambu was obtained, and its active compound, spilanthol, was isolated. The extract and spilanthol both exhibited cytotoxicity against gastric cancer cells. Furthermore, molecular docking experiments revealed that spilanthol has inhibitory potential against JAK1 and JAK2 proteins. These findings suggest that jambu extract and spilanthol could be potential candidates for the treatment of gastric carcinoma.
Scientists used a plant extract to create nanocrystalline CaFeO, which showed high photocatalytic and antibacterial activity, as well as low cytotoxicity. Potential applications include bioremediation and medical fields.
