  Synthesis of esters of phosphonoformic acid and their antiherpes activity

  摘要：

  Aliphatic and aromatic mono-, di-, and triesters of phosphonoformic acid (foscarnet) were synthesized. The triesters were prepared by the Michaelis-Arbuzov reaction and were hydrolyzed to di- and monoesters. The compounds were tested for antiviral activity on isolated herpes simplex virus type 1 (HSV-1) DNA polymerase, in a HSV-1 plaque reduction assay, and on a cutaneous HSV-1 infection in guinea pigs. None of the esters inhibited the activity of isolated HSV-1 polymerases. Monoesters with a free carboxylic group and diesters with an aromatic carboxylic ester function were active against the cutaneous herpes infection. Mono- and diesters with an aromatic phosphonic ester group also showed activity in the plaque-reduction assay. However, mono- and diesters with an aromatic phosphonic ester group also showed activity in the plaque-reduction assay. However, mono- and diesters with aliphatic carboxylic ester groups were inactive in all test systems. The results show that all three acidic groups of phosphonoformic acid must be free in order to get antiviral activity at the enzyme level. However, certain esters of this acid may be biotransformed to the acid itself to give antiherpes activity.

  The substituent effect on the geometrical selectivity in the Horner–Wadsworth–Emmons (HWE) reaction was studied employing several mixed phosphonoacetates. Their reactions with aromatic aldehydes showed a gradual change in Z-selectivity according to the electron-withdrawing ability of the phosphonate substituents, and there was a good correlation between the observed selectivities and 31P chemical shifts

  使用几种混合的膦酰基乙酸酯研究了霍纳-沃兹沃思-埃蒙斯（HWE）反应中取代基对几何选择性的影响。他们与芳族醛的反应表明，Z-选择性根据膦酸酯取代基的吸电子能力逐渐变化，并且所观察到的选择性与膦酰基乙酸酯的31 P化学位移之间具有良好的相关性。一些变量，例如金属阳离子和冠醚也影响了选择性。使用从头算和半经验计算的计算研究表明，吸电子取代基可稳定中间体以及过渡态，从而降低了增加Z的可逆性-产品。这与实验观察到的选择性一致。
