The research focuses on the development of potent non-nucleoside inhibitors targeting the measles virus RNA-dependent RNA polymerase complex (RdRp), which is crucial for viral replication. The study expands on a high-throughput screening hit compound 1 (16677) that can inhibit viral reproduction at 250 nM by targeting the RdRp. The experiments involve the synthesis and structure-activity relationship (SAR) analysis of a broad range of low nanomolar nonpeptidic measles virus inhibitors, with particular emphasis on the role of the trifluoromethyl (CF3) functionality. Various reactants, including acid chlorides, amines, and sulfonamide derivatives, are utilized in the synthesis of these inhibitors. The analyses encompass nuclear magnetic resonance (NMR) spectroscopy for structural characterization, elemental analysis for composition verification, and a quantitative structure-activity relationship (QSAR) study using Molecular Field Topology Analysis (MFTA) to predict the activities of the synthesized compounds and understand the impact of different structural modifications on their antiviral potency.
