制备方法与用途

2-甲基吡啶-3-硼酸

2-甲基吡啶-3-硼酸是一种有机中间体，可通过3-溴-2-甲基吡啶和三异丙基硼酸在单步反应中制备得到。此化合物可用于参与Suzuki偶联反应。

制备过程

在-78°C下，将3-溴-2-甲基吡啶（4.00g，23 mmol）与硼酸三异丙酯（6.40 mL，28 mmol）溶解于50 mL 4/1甲苯/THF混合溶剂中。随后，逐滴加入丁基锂（17 mL，28 mmol）。将反应物在30分钟内加热至-70°C，然后升温至20°C。接着，使用HCl（2 M）调节溶液pH值至1。向反应液中加入20 mL水，并用甲苯萃取。用水层中的1M NaOH进行中和后，再用二氯甲烷萃取。将水相浓缩干燥，用二氯甲烷洗涤白色固体。合并的有机层经硫酸钠干燥、过滤并进一步浓缩，最终得到2.10 g黄色油状物2-甲基吡啶-3-硼酸。质谱分析结果（ES+）显示其质量为138.2 (M+H)。

  A novel inhibitor of inducible NOS dimerization protects against cytokine-induced rat beta cell dysfunction

  摘要：

  Background and PurposeBeta cell apoptosis is a major feature of type 1 diabetes, and pro‐inflammatory cytokines are key drivers of the deterioration of beta cell mass through induction of apoptosis. Mitochondrial stress plays a critical role in mediating apoptosis by releasing cytochrome C into the cytoplasm, directly activating caspase‐9 and its downstream signalling cascade. We aimed to identify new compounds that protect beta cells from cytokine‐induced activation of the intrinsic (mitochondrial) pathway of apoptosis.Experimental ApproachDiabetogenic media, composed of IL‐1β, IFN‐γ and high glucose, were used to induce mitochondrial stress in rat insulin‐producing INS1E cells, and a high‐content image‐based screen of small molecule modulators of Casp9 pathway was performed.Key ResultsA novel small molecule, ATV399, was identified from a high‐content image‐based screen for compounds that inhibit cleaved caspase‐9 activation and subsequent beta cell apoptosis induced by a combination of IL‐1β, IFN‐γ and high glucose, which together mimic the pathogenic diabetic milieu. Through medicinal chemistry optimization, potency was markedly improved (6–30 fold), with reduced inhibitory effects on CYP3A4. Improved analogues, such as CAT639, improved beta cell viability and insulin secretion in cytokine‐treated rat insulin‐producing INS1E cells and primary dispersed islet cells. Mechanistically, CAT639 reduced the production of NO by allosterically inhibiting dimerization of inducible NOS (iNOS) without affecting its mRNA levels.Conclusion and ImplicationsTaken together, these studies demonstrate a successful phenotypic screening campaign resulting in identification of an inhibitor of iNOS dimerization that protects beta cell viability and function through modulation of mitochondrial stress induced by cytokines.

  to improve potency and reduce lipophilicity, resulting in a highly selective in vivo probe compound 32. We demonstrated dose-dependent in vivo efficacy and target engagement in Mer- and Axl-dependent efficacy models using two structurally differentiated and selective dual Mer/Axl inhibitors. Additionally, in vivo efficacy was observed in a preclinical MC38 immuno-oncology model in combination with anti-PD1
