  炔基苯并恶嗪和二氢喹唑啉作为半胱氨酸靶向共价弹头及其在选择性不可逆激酶抑制剂鉴定中的应用

  摘要：

  随着对共价药物的兴趣重新抬头，需要确定能够形成半胱氨酸键的新部分，这些部分与常用系统（如丙烯酰胺）不同。在此，我们报告了能够与半胱氨酸共价反应的新炔基苯并恶嗪和二氢喹唑啉部分的发现。它们作为化学生物探针和药物分子的替代亲电弹头的实用性通过位点选择性蛋白质修饰和结合到激酶药物支架中得到证明。鉴定出一种有效的 JAK3 激酶共价抑制剂，与相关的基于丙烯酰胺的抑制剂相比，它在整个激酶组中具有优异的选择性，并改善了体外药代动力学特征。此外，使用新型杂环作为半胱氨酸反应弹头以靶向 c-KIT 中的 Cys788，其中丙烯酰胺以前无法形成共价相互作用。这些新的反应性和选择性杂环弹头补充了当前的半胱氨酸共价修饰库，同时避免了通常与已建立的部分相关的一些限制。

  N-Acetic acid derivatives (I) of 2-substituted 1, 4-benzoxazines and benzothiazines were designed and synthesized for evaluation as new aldose reductase inhibitors. In general, 3-thioxo derivatives were more potent inhibitors of aldose reductase from human placenta in vitro than the corresponding 3-oxo derivatives. While many compounds (I) were not very effective in inhibiting sorbitol accumulation in the rat sciatic nerve in vivo, the 3-thioxo compounds bearing an isopropyl group at the 2-position showed highly potent activity in the in vivo assay. Compound 46 (AD-5467) was selected from this series as a candidate for further development.

  N-乙酸衍生物（I）的2-取代基1,4-苯并恶嗪和苯并噻嗪被设计合成，以评估其作为新型醛糖还原酶抑制剂的潜力。一般而言，3-硫代羰基衍生物在体外对人胎盘醛糖还原酶的抑制活性比相应的3-氧代衍生物更强。虽然许多化合物（I）在体内对大鼠坐骨神经山梨醇积累的抑制作用并不十分有效，但在体内试验中，2-位带有异丙基的3-硫代羰基化合物显示出极强的活性。从这一系列中选出化合物46（AD-5467）作为进一步开发的候选药物。
