structure-activity relationship study based on the previleged scaffolds led to the discovery of 2-(4-[(2'-chloro-[1,1'-biphenyl]-3-yl)methoxy]phenyl)sulfonyl}acetic acid (compound 20), which showed a better balance than compound 2 in terms of physicochemical properties, cytotoxicity profiles and pharmacokinetic properties. Subsequent in vivo studies demonstrated that compound 20 robustly improves the
游离脂肪酸受体1(FFA1)已成为介导葡萄糖刺激的胰岛素分泌的有吸引力的抗糖尿病靶标。已经报道了几种FFA1激动剂,但是其中许多具有较高的亲脂性和/或分子量。在这里,我们描述了具有减少化合物2相关的亲脂性,细胞毒性和β-氧化的多重优势的砜-羧酸部分的鉴定。基于旧支架的进一步结构-活性关系研究导致发现了2-((4-[(2'-氯-[1,1'-联苯] -3-基)甲氧基]苯基]磺酰基}乙酸(化合物20),显示出比化合物2更好的平衡在理化性质,细胞毒性特征和药代动力学性质方面。随后的体内研究表明,化合物20在正常模型和2型糖尿病模型中均能显着提高葡萄糖耐量,且无低血糖风险。与TAK-875诱发肝毒性的高风险相比,即使在较高剂量下,在化合物20的慢性毒性研究中也没有观察到明显的不良反应,例如肝和肾毒性。
