  Synthesis of 1,4-Disubstituted Pyrazolo[3,4-d]pyrimidines from 4,6-Dichloropyrimidine-5-carboxaldehyde: Insights into Selectivity and Reactivity

  摘要：

  Strategies for carrying out the reaction of 4,6-dichloropyrimidine-5-carboxaldehyde with both aromatic and aliphatic hydrazines to generate 1-substituted 4-chloropyrazolo[3,4-d]pyrimidines in a selective, high-yielding, and operationally simple manner are presented. For aromatic hydrazines, the reaction is performed at a high temperature in the absence of an external base. For aliphatic hydrazines, the reaction proceeds at room temperature in the presence of an external base. The observed selectivity and reactivity trends are rationalized through consideration of the proposed reaction mechanism. The 1-substituted 4-chloropyrazolo[3,4-d]pyrimidine products serve as versatile synthetic intermediates, through further functionalization of the 4-chloride moiety, enabling the rapid generation of a structurally diverse array of 1,4-disubstituted pyrazolo[3,4-d]pyrimidines.

  摘要：

  精氨酸酶在利什曼原虫中进行了多胺生物合成的第一步酶促步骤，代表了药物开发的有希望的目标。利什曼原虫中的多胺参与锥虫硫醚的合成，该合成可中和宿主巨噬细胞杀死寄生虫所产生的活性氧（ROS）和一氧化氮（NO）的氧化爆发。为了合成精氨酸酶抑制剂，合成了六个在苯基的4-位具有不同取代基的1-苯基-1H-吡唑并[3,4-d]嘧啶衍生物。最初所有化合物均以100 µM的浓度对亚马逊利什曼原虫ARG（LaARG）进行了测试，显示出36至74％的抑制活性。两种化合物1（R = H）和6（R = CF3）的精氨酸酶抑制率> 70％，IC50值分别为12 µM和47 µM。因此，分析了化合物1和6的LaARG抑制动力学，发现这些化合物通过非竞争性机制抑制酶，显示Kis值，三元复合酶-底物-抑制剂的解离常数为8.5±0.9 µM和29±5分别为µM。此外，分子对接研究表明这两种非竞争性抑制剂与不同的LaARG结合

  Strategies for carrying out the reaction of 4,6-dichloropyrimidine-5-carboxaldehyde with various hydrazines to generate 1-substituted 4-chloropyrazolo[3,4-d]pyrimidines in a selective and high-yielding manner are presented. For aromatic hydrazines, the reaction is performed in the absence of an external base, which promotes exclusive hydrazone formation. The hydrazones subsequently cyclize at an elevated temperature to form the desired pyrazolo[3,4-d]pyrimidine products. For aliphatic hydrazines, the reaction sequence proceeds as a single step in the presence of an external base.

  1-phenyl-1H-pyrazolo[3,4-d]pyrimidine derivatives with different substituents at the 4-position of the phenyl group were synthesized. All compounds were initially tested at 100 µM concentration against Leishmania amazonensis ARG (LaARG), showing inhibitory activity ranging from 36 to 74%. Two compounds, 1 (R=H) and 6 (R=CF3), showed arginase inhibition >70% and IC50 values of 12 µM and 47 µM, respectively.
