title: Studies on non-thiazolidinedione antidiabetic agents. 2. Novel oxyiminoalkanoic acid derivatives as potent glucose and lipid lowering agents.
abstract: We previously reported that (Z)-2-(4-[(5-methyl-2-phenyl-1, 3-oxazol-4-yl)methoxy]benzyloxyimino)-2-(4-phenoxyphenyl)acetic acid (3) showed potent glucose and lipid lowering effects in genetically obese and diabetic mice, KKA(y). This compound also showed transcriptional activity for peroxisome proliferator-activated receptor (PPAR)-gamma. We expanded on the structure-activity relationships of oxyiminoalkanoic acid derivatives based on this transcriptional activity (in vitro). Insertion of a carbon chain between the imino carbon and the carboxyl moiety of (Z)-2-(4-[(5-methyl-2-phenyl-1, 3-oxazol-4-yl)methoxy]benzyloxyimino)-2-phenylacetic acid (2) resulted in a marked increase in transcriptional activity at PPARgamma. In vivo potencies of synthesized compounds, which showed strong functional activity at PPARgamma, were tested using KKA(y) mice. Among these compounds, (E)-4-(4-[(5-methyl-2-phenyl-1, 3-oxazol-4-yl)methoxy]benzyloxyimino)-4-phenylbutyric acid (27) exhibited marked glucose and lipid lowering activity while showing no significant body weight gain. Compound (27) (TAK-559) showed favorable pharmacokinetic properties with good absorption and duration, and was considered as an attractive candidate for further evaluation.
