General description

Efavirenz, commercially known as Sustiva™ is a polycyclic aromatic hydrocarbon with benzene and oxazinan-2-one chromophores.

Application

Efavirenz has been used:
  • to assess its anti-porcine endogenous retrovirus (PERV) activity
  • in cytotoxicity assay
  • to investigate the solute-solvent effects of efavirenz by means combined time-dependent density functional theory (TD-DFT) and spectroscopic calculations

Biochem/physiol Actions

Efavirenz is a nonnucleoside reverse transcriptase inhibitor (NNRTI). It is an anti-HIV drug, commonly used in combination therapy for AIDs treatment. It is part of highly active antiretroviral therapy (HAART) for the treatment of a human immunodeficiency virus (HIV) type 1.
