Abstract: In this study, Pseudomonas fluorescens 4.9.3 isolated from a sponge sample was investigated for its secondary metabolites. Two metabolites were isolated, and their structures were elucidated by 1D-, 2D NMR and LC-MS/MS experiments. The new compound (1) was established as (5R)-N-(2-(1H-imidazol-4-yl)ethyl)-2-(2-hydroxyphenyl)-5-methyl-4,5-dihydrooxazole-4-carboxamide, while the known metabolite was determined as pre-pseudomonine.
