mechanism of action studies showed that leadagents 1 and 4 reduced virus replication by directly targeting IAV nucleoproteins and disrupting virus ribonucleoprotein export from the nucleus to the cytosol. On the basis of its high potential as an anti-IAV agent and its selectivity index >785, compound4 was found to be a promising candidate for further development against IAVs.
efficacy with minimum inhibitory concentrations starting from 125 µM. M. kansasii was the most susceptible species. Itaconamides derivedfrom sulfonamides or p-aminosalicylicacid were optimal for activity against extracellular mycobacteria. ICL1 was significantly inhibited by two compounds, with 2-methylene-4-[(4-nitrophenyl)amino]-4-oxobutanoic acid 1k being the most potent (36% inhibition at 10 µM),
