    • Bio Activity:

      Anti-infection; MedChem Express HY-10572
      Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI).;IC50 Value: 60 nM [1];Target: NNRTIs; HIV;In vitro: Efavirenz is a potent inhibitor of the wild-type HIV-1 RT (Ki = 2.93 nM) and exhibited a 95% inhibitory concentration of 1.5 nM for the inhibition of HIV-1 replicative spread in cell culture [2]. Efavirenz inhibited synthesis using an RNA PPT-primed substrate with an IC50 of 17 nM. In contrast to L-697661 and nevirapine, efavirenz also inhibited synthesis with the DNA PPT-primed substrate. However, with an IC50 of 345 nM, the activity of efavirenz was more than 20-fold less potent as an inhibitor of DNA PPT-primed synthesis compared with reactions in which an RNA PPT primer was used [3]. ;In vivo: Efavirenz occasions drug-lever responding in rats discriminating LSD from saline, and this effect is abolished by selective blockade of the 5-HT(2A) receptor. Similar to LSD, efavirenz induces head-twitch responses in wild-type, but not in 5-HT(2A)-knockout, mice [4] MedChem Express HY-10572
