Cabotegravir
Based on 14 publication(s) in Google Scholar
Cabotegravir (GSK-1265744) is a orally active and long-acting HIV integrase strand transfer inhibitor and organic anion transporter 1/3 (OAT1/OAT3) inhibitor with IC50 values of 2.5 nM, 0.41 μM and 0.81 μM for HIVADA, OAT3 and OAT1, respectively. Cabotegravir is primarily metabolized by uridine diphosphate glucuronosyltransferase (UGT) 1A1, with low potential to interact with other antiretroviral agents (ARVs). Cabotegravir can be used to research AIDS.

Cabotegravir (GSK-1265744) inhibits the HIV-1 integrase catalyzed strand transfer reaction with an IC50 of 3.0 nM in vitro. The antiviral EC50 against HIV-1 Ba-L is 0.22 nM and that against NL432 is 0.34 nM in PBMCs, 0.57 nM using CellTiter-Glo and 1.3 nM using MTT in MT-4, and 0.5 nM in the PHIV assay, which uses a pseudotyped self-inactivating virus[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
