(S)-N-(2,5-Dimethylphenyl)-1-(quinoline-8-ylsulfonyl)pyrrolidine-2-carboxamide as a Small Molecule Inhibitor Probe for the Study of Respiratory Syncytial Virus Infection
摘要:
A high-throughput, cell-based screen was used to identify chemotypes as inhibitors for human respiratory syncytial virus (hRSV). Optimization of a sulfonylpyrrolidine scaffold resulted in compound 50 that inhibited a virus-induced cytopathic effect in the entry stage of infection (EC50 = 2.3 +/- 0.8 mu M) with marginal cytotoxicity (CC50 = 30.9 +/- 1.1 mu M) and reduced viral titer by 100-fold. Compared to ribavirin, sulfonylpyrrolidine 50 demonstrated an improved in vitro potency and selectivity index.
