Selective S1P(4) receptor antagonists could be novel therapeutic agents for the treatment of influenza infection in addition to serving as a useful tool for understanding S1P(4) receptor biological functions. 5-(2,5-Dichlorophenyl)-N-(2,6-dimethylphenyl)furan-2-carboxamide was identified from screening the Molecular Libraries-Small Molecule Repository (MLSMR) collection and selected as a promising S1P(4) antagonist hit with moderate in vitro potency and high selectivity against the other family receptor subtypes (S1P(1-3,5)). Rational chemical modifications of the hit allowed the disclosure of the first reported highly selective S1P(4) antagonists with low nanomolar activity and adequate physicochemical properties suitable for further lead-optimization studies.
