Item Cytotoxicity, anti-poliovirus activity and in silico biological evaluation of constituents from Maytenus gonoclada (Celastraceae).(2014) Oliveira, Mauro Lúcio Gonçalves de; Assenço, Regina Aparecida Gomes; Silva, Grácia Divina de Fátima; Lopes, Júlio César Dias; Silva, Fernando César; Lanna, Maria Célia da Silva; Magalhães, José Carlos de; Duarte, Lucienir Pains; Vieira Filho, Sidney AugustoObjective: The in silico free access web tools PASS online and ChemMapper were used to predict potential biological activities of compounds 1 to 8 isolated from Maytenus gonoclada (Celastraceae). The constituents 4’-O-methylepigalocatequin (6), tingenone (7) and proanthocyanidin A (8), and ethanolic extracts were subjected to in vitro cytotoxicity using VERO cells and anti-Poliovirus assays. Methods: QSAR and molecular superposition, correlating the average number of pharmacophores were used in the prediction studies. Cellular line VERO ATCC CCL-81 was used to determine anti-Poliovirus effect, observed by colorimetric (MTT) method. The annexing V/propidium iodide assay was used to determine the occurrence of apoptosis in the cytotoxicity assays. Results: The experimental results found for constituents 6-8 were in accordance with observed data obtained through PASS online and ChemMapper simulation. Conclusion: Compound 7 showed higher cytotoxic and apoptosis induction properties, and 6 and 8 presented anti-Poliovirus activity.
