Synthesis and Anti-HIV Activity of Different Novel Nonclassical Nucleosides
摘要:
A series of different novel nonclassical nucleosides have been synthesised and evaluated for their inhibitory activity against human immunodeficiency virus (HIV) replication in MT-4 cells.
N-Hydroxymethylation of 3-Aryl-2-cyanoprop-2-enethioamides
摘要:
Hydroxymethylation of (E)-3-aryl-2-cyanoprop-2-enethioamides with an aqueous alcoholic solution of formaldehyde has afforded (E)-3-aryl-N-(hydroxymethyl)-2-cyanoprop-2-enethioamides. The predictive analysis of the biological activity of the obtained compoundsin silicohas been carried out.

The 3-aryl-2-cyanoacrylamide scaffold was designed as core pharmacophore for inhibitors of the Dengue and West Nile virus serine proteases (NS2B-NS3). A total of 86 analogs was prepared to study the structure-activity relationships in detail. Thereby, it turned out that the electron density of the aryl moiety and the central double bond have a crucial influence on the activity of the compounds, whereas the influence of substituents of the amide residue is less relevant. The para-hydroxy substituted analog was found to be the most potent inhibitor in this series with a K(i)-value of 35.7 mu M at the Dengue and 44.6 mu M at the West Nile virus protease. The aprotinin competition assay demonstrates a direct interaction of the inhibitor molecule with active centre of the Dengue virus protease. The target selectivity was studied in a counterscreen with thrombin and found to be 2.8:1 in favor of DEN protease and 2.3:1 in favor of WNV protease, respectively. (C) 2011 Elsevier Ltd.
