Secnidazole hemihydrate (RP-14539), an orally ingestible azole derivative antibiotic and imidazole-based Serratia marcescens virulence suppressor, analogously inhibits acylhomoserine lactones, mitigating Pseudomonas aeruginosa pathogenicity through quorum sensing (QS) disruption. This compound exhibits broad-spectrum antimicrobial efficacy against numerous anaerobic Gram-negative and Gram-positive bacteria in vitro. Its therapeutic application spans the study and treatment of ailments including amoebiasis, giardiasis, and bacterial vaginitis [1] [2] [3].
