1、4'-C-substituted-2'-deoxynucleosides: a family of antiretroviral agents which are potent against drug-resistant HIV variants H Ohrui 1, H Mitsuya

Abstract In the past years, a variety of 4'-C-substituted-2'-deoxynucleosides (4'SdNs) were designed, synthesized, and examined as potential therapeutics against human immunodeficiency virus (HIV) infection and certain such analogues proved to exert potent activity against HIV-1 in vitro. Unlike currently available nucleoside reverse transcriptase (RT) inhibitors such as 3'-azido-3'-deoxythymidine (AZT), which have the 2',3'-dideoxy configuration and thereby cause DNA chain termination in the elongating proviral DNA, 4'SdNs do retain the 3'-alpha-OH moiety but also appear to work against retrovirus as proviral DNA chain terminators. Several 4'SdNs have been shown to be active against various laboratory and clinical HIV-1 strains including known drug-resistant HIV-1 variants. Among such 4'SdNs is 4'-azido-2'-deoxythymidine (4'-AZT) which exerts potent antiviral activity against wild type and AZT-resistant clinical HIV strains. More anti-HIV 4'SdNs have recently been reported including 4'-ethynylthymidine, 4'-ethynyl-2'-deoxy-D-ribofuranosyl-2,6-diaminopurine (4'-E-dDAP), 4'-ethynyl-2'-deoxyguanosine (4'-E-dG) and 4'-ethynyl-2'-deoxyadenosine (4'-E-dA). The latter three analogues are highly potent against HIV-1 and HIV-2 with EC50 values ranging from 0.0003 to 0.01 microM and have favorable cytotoxicity profiles with selective index (SI) values ranging from 975 to 2600. These 4'-ethynyl-2'-deoxynucleosides also exert potent activity against all known drug-resistant HIV-1 variants including the multi-dideoxynucleoside-resistant HIV and the variants with the 6-base pair inserts. Some of these compounds have favorable pharmacological properties and further development as potential therapeutics against HIV-1 infection is warranted.

Abstract 4'-Ethynyl-2-fluoro-2'-deoxyadenosine (EFdA) and 4'-ethynyl-2'-deoxyadenosine (EdA) are nucleoside analogues which inhibit human immunodeficiency virus type 1 (HIV-1) reverse transcriptase. EdAP, a cyclosaligenyl (cycloSal) phosphate derivative of EdA, inhibits the replication of the influenza A virus. The common structural feature of these compounds is the ethynyl group at the 4'-position. In this study, these nucleoside analogues were prepared by a common synthetic strategy starting from the known 1,2-di-O-acetyl-D-ribofuranose. Biological evaluation of EdAP revealed that this compound reduced hepatitis B virus (HBV) replication dose-dependently without cytotoxicity against host cells tested in this study.

3、Effects of substitutions at the 4' and 2 positions on the bioactivity of 4'-ethynyl-2-fluoro-2'-deoxyadenosine

Abstract Nucleos(t)ide reverse transcriptase inhibitors (NRTIs) form the backbone of most anti-HIV therapies. We have shown that 4'-ethynyl-2-fluoro-2'-deoxyadenosine (EFdA) is a highly effective NRTI; however, the reasons for the potent antiviral activity of EFdA are not well understood. Here, we use a combination of structural, computational, and biochemical approaches to examine how substitutions in the sugar or adenine rings affect the incorporation of dA-based NRTIs like EFdA into DNA by HIV RT and their susceptibility to deamination by adenosine deaminase (ADA). Nuclear magnetic resonance (NMR) spectroscopy studies of 4'-substituted NRTIs show that ethynyl or cyano groups stabilize the sugar ring in the C-2'-exo/C-3'-endo (north) conformation. Steady-state kinetic analysis of the incorporation of 4'-substituted NRTIs by RT reveals a correlation between the north conformation of the NRTI sugar ring and efficiency of incorporation into the nascent DNA strand. Structural analysis and the kinetics of deamination by ADA demonstrate that 4'-ethynyl and cyano substitutions decrease the susceptibility of adenosine-based compounds to ADA through steric interactions at the active site. However, the major determinant for decreased susceptibility to ADA is the 2-halo substitution, which alters the pKa of N1 on the adenine base. These results provide insight into how NRTI structural attributes affect their antiviral activities through their interactions with the RT and ADA active sites.
