5-(3,3-diMethylbut-1-yn-1-yl)-3-(N-(4-hydroxycyclohexyl)-4-MethylcyclohexanecarboxaMido)thiophene-2-carboxylic acid

Lomibuvir (VX-222), a selective, non-nucleoside polymerase inhibitor, targets thumb pocket 2 of the HCV NS5B polymerase (RdRp) with a Kd of 17 nM. Lomibuvir inhibits the 1b/Con1 HCV subgenomic replicon with an EC50 of 5.2 nM. Lomibuvir preferentially inhibits elongative RNA synthesis rather than de novo-initiated RNA synthesis[1].

ChEBI: 5-(3,3-dimethylbut-1-ynyl)-3-[(4-hydroxycyclohexyl)-[(4-methylcyclohexyl)-oxomethyl]amino]-2-thiophenecarboxylic acid is a thiophenecarboxylic acid.
