Synthesis and antiviral activity of acyclovir-5′-(phenyl methoxy alaninyl) phosphate as a possible membrane-soluble nucleotide prodrug
摘要:
We describe a synthesis of acyclovir-5'-(phenyl methoxy alaninyl) phosphate (2) from acyclovir (1). This compound was designed to act as a lipophilic, membrane-soluble prodrug of the free nucleotide. However, the biological activities of this derivative against a range of viruses indicated poor intracellular phosphate delivery, in marked contrast to the earlier successful delivery of several dideoxy anti-HIV nucleotides.

Recently, it has been reported that phosphorylated acyclovir (ACV) inhibits human immunodeficiency virus type 1 (HIV-1) reverse transcriptase in a cell-free system. To deliver phosphorylated ACV inside cells, we designed ACV monophosphorylated derivatives using ProTide technology. We found that the L-alanine derived ProTides show anti-HIV activity at noncytotoxic concentrations; ester and aryl variation was tolerated, ACV ProTides with other amino acids, other than L-phenylalanine, showed no detectable activity against HIV in cell culture. The inhibitory activity of the prodrugs against herpes simplex virus (HSV) types-1 and -2 and thymidine kinase-deficient HSV-1 revealed different structure-activity relationships but was again consistent with successful nucleoside kinase bypass. Enzymatic and molecular modeling studies have been performed in order to better understand the antiviral behavior of these compounds. ProTides showing diminished carboxypeptidase lability translated to poor anti-HIV agents and vice versa, so the assay became predictive.
