Discovery of a Potent and Highly Selective Dipeptidyl Peptidase IV and Carbonic Anhydrase Inhibitor as “Antidiabesity” Agents Based on Repurposing and Morphing of WB-4101
multidrug therapies and the relevance of dipeptidylpeptidaseIV (DPP IV) and carbonic anhydrases (CAs II and V) in T2DM and in the weight loss, we report a new class of multitarget ligands targeting the mentioned enzymes. We started from the known α1-AR inhibitor WB-4101, which was progressively modified through a tailored morphing strategy to optimize the potency of DPP IV and CAs while losing the adrenergic
2 型糖尿病 (T2DM) 患者的管理正在从以心脏为中心转变为以体重为中心,或者更好的是,以脂肪为中心的治疗。考虑到多药治疗的缺点以及二肽基肽酶 IV (DPP IV) 和碳酸酐酶 (CAs II 和 V) 在 T2DM 和体重减轻中的相关性,我们报告了一类新的多靶点配体靶向上述酶。我们从已知的 α 1 -AR 抑制剂 WB-4101 开始,通过定制的变形策略对其进行逐步修改,以优化 DPP IV 和 CA 的效力,同时失去肾上腺素能活性。获得的化合物12显示出令人满意的 DPP IV 抑制作用,具有良好的选择性 CA 特征(DPP IV IC 50:0.0490 μM;CA II Ki 0.2615 μM;CA VA K i 0.0941 μM;CA VB K i 0.0428 μM)。此外,其在 Caco-2 中的 DPP IV 抑制活性及其可接受的前 ADME/Tox 特征表明它是此类新型多靶点配体中的先导化合物。

We describe the discovery and the structure-activity relationship of a new series of quinoline derivativesacting as selective and highly potent noncompetitive mGlu1 antagonists. We first identified cis-10 as a fairly potent mGlu1 antagonist (IC(50) = 20 nM) in a cell-based signal transduction assay on the rat mGlu1 receptor expressed in CHO-K1 cells, and then we were able to design and synthesize
biologically active compounds structurally include the enantiopure 2‐substituted‐1,4‐benzodioxane scaffold. The straightforward racemization that affects reactions involving most of the common chemical reactives is thus a crucial issue. The developing of a completely stereo‐controlled synthetic route that does not affect the enantiomeric excess is consequently mandatory. It is also important to set up a reliable
