Herein we report 6-ethoxy-6-oxo-5-(2-phenylhydrazono) hexanoic acid and 3-(2-carboxyethyl)-1H-indole- 2-carboxylic acid derivatives as synthetically accessible leads for human kynurenine aminotransferase-I (KAT-I) inhibitors. In total, 12 compounds were synthesized and their biological activities were determined using the HPLC-UV based KAT-I inhibition assay. Of the 12 compounds synthesized, 10 were found to inhibit human KAT-I and the most active compound was found to be 5-(2-(4-chlorophenyl) hydrazono)-6-ethoxy-6-oxohexanoic acid (9a) with an IC50 of 19.8 mu M.
