Oseltamivir represents one of the most successful neuraminidase (NA) inhibitors in the current anti-influenza therapy. The 150-cavity of NA was identified as an additional binding pocket, and novel NA inhibitors have been designed to occupy the 150-cavity based on the structure information of oseltamivir carboxylate (OC) in complex with NA. In this study, a series of C-5-NH2-acyl derivatives of OC
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。

A wide range of novel 2-(β-D-ribofuranosyl)pyrimidines, including RF-containing derivatives, have been synthesized by the reaction of (β-D-ribofuranosyl)formamidine with various dielectrophilic substrates such as 3-alkoxy- and 3-chloro-1-(polyfluoroalkyl)propen-1-ones, 3-nitro- and 3-(phenylethynyl)chromones and heteroaryl acetylenic ketones.

under a variety of conditions. These include refluxing 2 with 1 in ethanol for 8-16 hrs and reaction of 1 with 2 in presence of large excess of hydrochloric acid.6 Cyclization of 2 with 1 in refluxing ethanol in presence of triethylamine' and 10% aceticacid have also been reported.8 However, all these methods suffer from certain disadvantages like long reaction times,' strongly acidic6 or basic conditions

decarbonylation of methyl 1-aryl-3-(het)aroyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates afforded 8-substituted methyl 3-(het)aroyl-4-oxo-1,4-dihydroquinoline-2-carboxylates. X-ray diffraction studies revealed no hydrogen bonds in the crystals of the compounds obtained. According to spectral data, hydrogen bonding is possible in concentrated solutions of 8-substituted methyl 4-oxo-1,4-dihydroq
