  carboxyl-containing DPP-4 inhibitors were highly potent but were poorly bioavailable. Esters of the carboxyl analogs exhibited a significant DPP-4 potency loss albeit with enhanced oral absorption. Herein, we described identification and structure–activity relationship (SAR) exploration of a novel series of benzoic acid and ester derivatives as low single-digit nanomolar DPP-4 inhibitors. Importantly, the

  我们之前报道的含羧基的 DPP-4 抑制剂非常有效，但生物利用度很低。羧基类似物的酯表现出显着的 DPP-4 效力损失，尽管具有增强的口服吸收。在此，我们描述了一系列新型苯甲酸和酯衍生物作为低个位数纳摩尔 DPP-4 抑制剂的鉴定和构效关系 (SAR) 探索。重要的是，酯显示出与酸对应物相当的活性。分子模拟显示酯采用与酸相似的结合方式。此外，所选择的酯和酸表现出高选择性和低细胞毒性，以及良好的代谢稳定性。更重要的是，这些酯类具有出色的口服药代动力学特征。最好的复合酯图19b在体内证明了长时间的 DPP-4 抑制，并在正常和 db/db 小鼠中显着改善了葡萄糖耐量，同时确保了慢性治疗中的降糖效力。我们的结果支持化合物19b可作为治疗 2 型糖尿病的潜在候选药物。
