  摘要：

  嘌呤等排体在药物设计和开发中提供了极好的机会。使用天然嘌呤的等排体作为构建新治疗剂的支架已成为药物化学的有效策略。受到与异鸟嘌呤的相似性的启发，我们尝试开发一种实用的方法来制备 5-氮杂-异鸟嘌呤。探索了几种合成方法，以建立用于制备这些化合物的稳健通用方案。证明了 1,2,4-三唑并[1,5-a][1,3,5]三嗪（5-氮杂嘌呤）的 C-5 和 C-7 亲电中心对亲核试剂的反应性存在显着差异。制备 5-氮杂-异鸟嘌呤的最实用和通用的方法涉及乙氧羰基异硫氰酸酯与 5-氨基三唑的区域选择性反应。所得产物的分子内闭环，然后进行 S-甲基化，得到 7-甲硫基-2-苯基-1,2,4-三唑并[1,5-a][1,3,5]triazin-5-one，可与各种胺有效胺化。由此产生的 5-氮杂-异鸟嘌呤类似于一种已知的嘌呤核苷磷酸化酶抑制剂，对于作为潜在抗癌剂的进一步研究可能很有趣。

  antiepileptic drugs, a series of 2,5-disubstituted [1,2,4]-triazolo[1,5-a]pyrimidine-7(4H)-one derivatives were designed and synthesized. Spontaneous Ca2+ oscillations (SCOs) of cortical neurons were used for in vitro phenotypic screening. Maximal electroshock test (MES) and pentylenetetrazole (PTZ) test were used to access their anticonvulsant activity, and rotarod test was used to estimate their neurotoxicity

  为了寻找更有效，更安全的抗癫痫药，设计并合成了一系列2,5-二取代的[1,2,4]-三唑并[1,5-a]嘧啶-7（4H）-one衍生物。皮层神经元的自发Ca 2+振荡（SCO）用于体外表型筛选。使用最大电击试验（MES）和戊四唑（PTZ）试验来获得其抗惊厥活性，并使用rotarod试验评估其神经毒性。体外模型中的活性化合物在戊四氮（PTZ）诱发的癫痫模型中特别有效，但在最大电击（MES）模型中无效，与常用药物相比，更重要的是具有较低的神经毒性。其中，化合物5c和5e在PTZ诱发的癫痫模型中显示出显着的抗惊厥活性，ED50值分别为31.81 mg / kg和40.95 mg / kg，分别。这些化合物具有改善的神经毒性，其保护指数（PI = TD50 / ED50）值分别为17.22和9.09。最后，我们证明了化合物5c和5e主要作为正调节剂作用于GABAA受体，但没有钠通道。因此，本研究为癫痫的进一步研究提供了潜在的候选者。

  approach toward N-acylated aminotriazoles is reported, enabling the compounds’ screening against FXIIa and thrombin. This approach afforded low-nanomolar FXIIa and thrombin inhibitors with no off-targeting of the other tested serine proteases. Selected compounds were shown to be covalent inhibitors of FXIIa and demonstrated anticoagulant properties in vitro, influencing the intrinsic blood coagulation

  We herein report the conventional and microscale parallel synthesis of selective inhibitors of human blood coagulation factor XIIa and thrombin exhibiting a 1,2,4-triazol-5-amine scaffold. Structural variations of this scaffold allowed identifying derivative 21i, a potent 29 nM inhibitor of FXIIa, with improved selectivity over other tested serine proteases and also finding compound 21m with 27 nM

  我们在此报告了常规和微观并行合成的人类凝血因子XIIa和凝血酶的选择性抑制剂，这些抑制剂表现出1,2,4-三唑-5-胺骨架。该支架的结构变异允许鉴定衍生物21i（一种有效的FXIIa抑制剂29nM），具有比其他经过测试的丝氨酸蛋白酶更高的选择性，还可以发现化合物21m对凝血酶具有27 nM的抑制活性。首次证明酰化的1,2,4-三唑-5-胺具有抗凝特性，并具有影响凝血酶和癌细胞诱导的血小板凝集的能力。进行的质谱分析和分子建模使我们能够发现合成的抑制剂与FXIIa活性位点之间以前未知的相互作用，从而揭示了FXIIa抑制的机理细节。合成的化合物代表了开发新的抗血栓药物或化学工具以研究FXIIa和凝血酶在生理和病理过程中的作用的有希望的起点。
