A new series of non-nucleoside reverse transcriptase inhibitors based on an imidazole-amide biarylether scaffold has been identified and shown to possess potent antiviral activity against HIV-1, including the NNRTI-resistant Y188L mutated virus. X-ray crystallog. of inhibitors bound to reverse transcriptase, including a structure of the Y188L RT protein, was used extensively to help identify and optimize the key hydrogen-bonding motif. This led directly to the design of compound (I) that exhibits remarkable antiviral activity (EC₅₀ < 1 nM) against a wide range of NNRTI-resistant viruses and a favorable pharmacokinetic profile across multiple species. This study involved multiple reactions and reactants, such as 2-Chloro-4-sulfamoylbenzoic acid (cas: 53250-84-3Category: chlorides-buliding-blocks).

2-Chloro-4-sulfamoylbenzoic acid (cas: 53250-84-3) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion.
