奥司他韦是当前抗流感治疗中最成功的神经氨酸酶(NA)抑制剂之一。 NA 的 150 个空腔被确定为一个额外的结合袋,并且根据羧酸奥司他韦 ( OC ) 与 NA 复合物的结构信息,设计了新型 NA 抑制剂来占据 150 个空腔。本研究合成了一系列含有吡唑部分的OC的C-5-NH 2 -酰基衍生物。几种衍生物对 NA 表现出显着的抑制活性。此外,计算机ADME评估表明,该衍生物具有类似药物的特性,比OC具有更高的口服吸收率和更大的细胞渗透性。此外,分子对接研究表明,衍生物与 NA 酶活性位点和 150 腔相互作用,正如预期的那样。研究结果为OC的进一步结构优化提供了有用的信息。

transformation of 3/5-trifluoromethylpyrazoles derivative into the corresponding NH-pyrazole-3/5-carboxylic acids. Moreover, from 4- or 5-iodinated-3/5-trifluoromethylpyrazoles buildingblocks and the use of Suzuki–Miyaura or Negishi reactions followed by the trifluoromethyl hydrolysis, we illustrate short and original accesses to many series of NH-pyrazole-3/5-carboxylic acids otherwise difficult to prepare.
antiandrogen because of its unique chemical structure and good activity against androgen receptor (AR). Herein, the structure-activity relationship of ODM-201 was studied, and 37 analogues were synthesized. Half of them exhibited similar or better anti-AR transcriptional activity compared to ODM-201. In addition, the inhibitory activity of compound 28t against the two resistant mutants (AR-F876L and AR-T877A)
