  Synthesis and antischistosomal activity of certain pyrazolo[1,5-a]pyrimidines

  摘要：

  Several 7-hydroxypyrazolo[1,5-a]pyrimidines (1-21), 7-mercaptopyrazolo[1,5-a]pyrimidines (37-49), and 4-alkylpyrazolo[1,5-a]pyrimidin-7-ones (50-55) and the corresponding 4-alkylpyrazolo[1,5-a]pyrimidine-7-thiones (56-60) were synthesized and tested for antischistosomal activity against Schistosoma mansoni. Of the compounds examined, the greatest degree of activity in vitro was found with the 7-mercaptopyrazolo[1,5-a]pyrimidines. In particular, compounds 37 and 47 proved lethal at 100 micrograms/mL after an exposure of only 1 h. The 7-hydroxypyrazolo[1,5-a]-pyrimidines were not as active. None of the compounds exhibiting in vitro activity were active against S. mansoni in vivo.

  Janus激酶3抑制剂的新型铰链结合母题：Tofacitinib生物等位基因的全面的结构-活性关系研究。

  摘要：

  Janus激酶（JAKs）是关键参与细胞因子信号传导的胞质酪氨酸激酶家族。JAK已被证明是治疗炎症和骨髓增生性疾病的有效靶标，两种抑制剂托法替尼和鲁索替尼最近获得了市场许可。尽管取得了成功，但JAK系列中的选择性仍然是一个主要问题。两种批准的化合物都具有共同的7 H-吡咯并[2,3- d]嘧啶铰链结合基序，关于在该杂环核心上耐受的修饰知之甚少。在当前的研究中，制备了托法替尼生物等排体库并针对JAK3进行了测试。这些化合物具有托法替尼哌啶基侧链，而铰链结合基序被模仿其药效基团的各种杂环所取代。考虑到从分子模型获得的希望，大多数化合物被证明是活性很差的。然而，发现了在这一系列新型化学型中恢复活性的策略，并推论出关键的结构-活性关系。提出的化合物可作为开发新型JAK抑制剂的起点，并可作为计算机模拟模型的有价值的训练集。
