  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, KKAy. This compound also showed transcriptional activity for peroxisome proliferator-activated receptor (PPAR)-γ. 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 PPARγ. In vivo potencies of synthesized compounds, which showed strong functional activity at PPARγ, were tested using KKAy 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.

  我们之前报道过，(Z)-2-4-[(5-甲基-2-苯基-1,3-恶唑-4-基)甲氧基]苄氧亚胺}-2-(4-苯氧基苯基)乙酸 (3) 在基因肥胖和糖尿病小鼠 KKAy 中表现出显著的降糖和降脂效果。该化合物还显示出对过氧化物酶体增殖物激活受体 (PPAR)-γ 的转录活性。我们基于这种转录活性（体外）扩展了氧亚胺烷酸衍生物的结构—活性关系。在 (Z)-2-4-[(5-甲基-2-苯基-1,3-恶唑-4-基)甲氧基]苄氧亚胺}-2-苯基乙酸 (2) 的亚胺碳与羧基之间插入碳链，显著提高了 PPARγ 的转录活性。合成化合物在 KKAy 小鼠中进行了体内效能测试，这些化合物在 PPARγ 上显示出强的功能活性。在这些化合物中，(E)-4-4-[(5-甲基-2-苯基-1,3-恶唑-4-基)甲氧基]苄氧亚胺}-4-苯基丁酸 (27) 展示了显著的降糖和降脂活性，同时未显示出明显的体重增加。化合物 (27) (TAK-559) 显示出良好的药代动力学特性，具备良好的吸收和持续时间，因此被认为是进一步评估的有吸引力的候选者。
