  Synthesis of Tamiflu and its Phosphonate Congeners Possessing Potent Anti-Influenza Activity

  摘要：

  Using D-xylose as an appropriate chiral precursor, we have synthesized active neuraminidase inhibitor oseltamivir, antiflu drug Tamiflu, and novel phosphonate congeners that exhibit even stronger antiflu activities by inhibiting the neuraminidases of the wildtype and H274Y mutant of H1N1 and H5N1 viruses. Molecular modeling of the neuraminidase-phosphonate complex indicates a pertinent binding mode of the phosphonate with three arginine residues in the active site. Discovery of such potent neuraminidase inhibitors will offer an opportunity to the development of new anti-influenza drugs.

  Tamiphosphor monoesters as effective anti-influenza agents

  摘要：

  Oseltamivir is a potent neuraminidase inhibitor for influenza treatment. By replacing the carboxylate group in oseltamivir with phosphonate monoalkyl ester, a series of tamiphosphor derivatives were synthesized and shown to exhibit high inhibitory activities against influenza viruses. Our molecular modeling experiments revealed that influenza virus neuraminidase contains a 371-cavity near the S1-site to accommodate the alkyl substituents of tamiphosphor monoesters to render appreciable hydrophobic interactions for enhanced affinity. Furthermore, guanidino-tamiphosphor (TPG) monoesters are active to the oseltamivir-resistant mutant. TPG monohexyl ester 4e having a more lipophilic alkyl substituent showed better cell permeability and intestinal absorption than the corresponding monoethyl ester 4c, but both compounds showed similar bioavailability. Intranasal administration of TPG monoesters at low dose greatly improved the survival rate of mice infected with lethal dose of H1N1 influenza virus, whereas 4c provided better protection of the infected mice than oseltamivir and other phosphonate congeners by oral administration.

  Novel phosphonate compounds are described. The compounds have activity as neuraminidase inhibitors against wild-type and H274Y mutant of H1N1 and H5N1 viruses. The present disclosure also provides an enantioselective synthetic route to known neuraminidase inhibitors oseltamivir and the anti-flu drug Tamiflu®, as well as novel phosphonate compounds, via D-xylose. Another efficient and flexible synthesis of Tamiflu and the highly potent neuraminidase inhibitor Tamiphosphor was also achieved in 11 steps and >20% overall yields from the readily available fermentation product (1S-cis)-3-bromo-3,5-cyclohexadiene-1,2-diol. Most of the reaction intermediates were obtained as crystals without tedious purification procedures. The key transformations include an initial regio- and stereoselective bromoamidation of a bromoarene cis-dihydrodiol, as well as the final palladium-catalyzed carbonylation and phosphonylation.

  本文描述了新型膦酸盐化合物。这些化合物对H1N1和H5N1病毒的野生型和H274Y突变体具有神经氨酸酶抑制剂活性。本公开还提供了一种手性选择性的合成路线，可通过D-木糖合成已知的神经氨酸酶抑制剂奥司他韦和抗流感药物达菲®，以及新型膦酸盐化合物。另外，还通过11个步骤和>20％的总收率，从易得到的发酵产物（1S-cis）-3-溴-3,5-环己二烯-1,2-二醇中实现了达菲和高效神经氨酸酶抑制剂Tamiphosphor的有效灵活合成。大多数反应中间体都以晶体形式获得，无需繁琐的纯化程序。关键的转化包括最初的区域和立体选择性的溴胺化反应，以及最后的钯催化的羰基化和膦酸盐化反应。
