| Research Abstract |
Recently, MALDI-MS has been used for low-molecular-weight metabolite analysis because it is a highly sensitive, high-throughput, and low sample-consuming technique. Although metabolites are predominantly organic acids, negative ionization mode has rarely been utilized due to poor sensitivity with commonly used matrices such as 9-aminoacridine (9-AA). Our purpose is synthesis and evaluation of new matrices for low-molecular metabolite MALDIMS analysis in negative mode. More than 60 compounds including acridine, anthracene and quinoline derivatives were synthesized as MALDI-MS matrix candidates. Using these synthetic matrices, 230 kinds of low-molecular weight metabolites were measured by MALDI-TOF-MS in negative ionization mode. Several new synthetic matrices were found to be more efficient than 9-AA. Especially, aminoanthracene derivatives provided much better analyte signals allowing 51 kinds of amino acid derivatives to be detected in negative mode.
