Diterpenes isolated from Canistrocarpus cervicornis with virucidal activity against HIV-1: an in silico evaluation.

HIV is a public health problem, which makes necessary the development of new drugs. Natural products are known for their anti-HIV potential and a good strategy to suggest its mechanism of action is using in silico tools. Herein, diterpenes 1 - 3 had the binding mode evaluated in the HIV-1 glycoprotein; and properties ADMET in silico performed. In molecular docking important interactions between the hydrophobic cavity, and 1 and 2 were observed. In the molecular dynamics, 1 remained stable covering the entire hydrophobic cavity and performed hydrogen bond during all simulation. ADMET evaluation showed good properties for the diterpenes. Based on these findings, it was possible to suggest the potential from natural products as entry inhibitor and HIV-1 treatment.
