  Discovery of a Series of Phosphonic Acid-Containing Thiazoles and Orally Bioavailable Diamide Prodrugs That Lower Glucose in Diabetic Animals Through Inhibition of Fructose-1,6-Bisphosphatase

  摘要：

  Oral delivery of previously disclosed purine and benzimidazole fructose-1,6 bisphosphatase (FBPase) inhibitors via prodrugs failed, which was likely due to their high molecular wright (> 600) Therefore, a smaller scaffold was desired, and a series of phosphonic acid-containing thiazoles, which exhibited high potency against human liver FBPase (IC(50) of 10-30 nM) and high selectivity relative to other 5'-adenosinemonophosphate (AMP)-binding enzymes, were discovered using a structure-guided drug design approach The initial lead compound (30j) produced profound glucose lowering in rodent models of type 2 diabetes mellitus (T2DM) after parenteral administration Various phosphonate prodrugs were explored without success, until a novel phosphonic diamide prodrug approach was Implemented, which delivered compound 30j with good oral bioavailability (OBAV) (22-47%) Extensive lead optimization of both the thiazole FBPase inhibitors and their prodrugs culminated in the discovery of compound 35n (MB06322) as the first oral FBPase inhibitor advancing to human clinical trials as a potential treatment for T2DM

  discoveries of a low molecular weight inhibitor series with increased potency and a phosphonate prodrug class suitable for their oral delivery. The lead inhibitor, 10A, was designed with the aid of X-ray crystallography and molecular modeling to bind to the allosteric AMP binding site of FBPase. High potency (IC50 = 16 nM) and FBPase specificity were achieved by linking a 2-aminothiazole with a phosphonic

  肝脏产生过多的葡萄糖，加上肌肉、脂肪和肝脏对葡萄糖的摄取和代谢减少，导致 2 型糖尿病患者的血糖水平长期升高。通过减少葡萄糖产生来治疗糖尿病的努力主要集中在糖异生途径和该途径中的限速酶，如果糖-1,6-双磷酸酶 (FBPase)。第一种有效的 FBPase 抑制剂是使用结构引导的药物设计策略 (Erion, MD; et al. J. Am. Chem. Soc. 2007, 129, 15480-15490) 鉴定的，但证明难以口服给药。在此处，我们报告了一系列口服生物可利用 FBPase 抑制剂的合成和表征，这些抑制剂是在结合发现具有增加效力的低分子量抑制剂系列和适合其口服给药的膦酸盐前药类别之后确定的。先导抑制剂 10A 是在 X 射线晶体学和分子建模的帮助下设计的，用于与 FBPase 的变构 AMP 结合位点结合。高效力 (IC50 = 16 nM) 和 FBPase 特异性是通过将
