Synthesis and antiviral activity of N-phenylbenzamide derivatives, a novel class of enterovirus 71 inhibitors.

A series of novel N-phenylbenzamide derivatives were synthesized and their anti-EV 71 activities were assayed in vitro. Among the compounds tested, 3-amino-N-(4-bromophenyl)-4-methoxybenzamide (1e) was active against the EV 71 strains tested at low micromolar concentrations, with IC50 values ranging from 5.7 ± 0.

Synthesis and antiviral activity of substituted bisaryl amide compounds as novel influenza virus inhibitors.

The influenza virus is a persistent cause of mortality and morbidity on an annual basis and thus presents itself as an important target for pharmaceutical investigation. In this work, substituted bisaryl amide compounds were found to be a new class of potential anti-influenza agents, and a series of substituted bisaryl amide compounds were synthesised and evaluated for their anti-influenza virus activities. The analysis of the results produced a preliminary structure-activity relationship study (SAR).

Host apolipoprotein B messenger RNA-editing enzyme catalytic polypeptide-like 3G is an innate defensive factor and drug target against hepatitis C virus.

Unlabelled: Host cellular factor apolipoprotein B messenger RNA (mRNA)-editing enzyme catalytic polypeptide-like 3G (hA3G) is a cytidine deaminase that inhibits a group of viruses including human immunodeficiency virus-1 (HIV-1). In the continuation of our research on hA3G, we found that hA3G stabilizing compounds significantly inhibited hepatitis C virus (HCV) replication. Therefore, this study investigated the role of hA3G in HCV replication.
