A new class of 2-substitutedbenzoxazole carboxamides are presented as potent functional 5-HT3 receptor antagonists. The chemical series possesses nanomolar in vitro activity against human 5-HT3A receptors. A chemistry optimization program was conducted and identified 2-aminobenzoxazoles as orally active 5-HT3 receptor antagonists with good metabolic stability. These novel analogues possess drug-like
