Design, synthesis, and biological evaluation of novel 4-aminopiperidinyl-linked 3,5-disubstituted-1,2,6-thiadiazine-1,1-dione derivatives as HIV-1 NNRTIs KU Leuven
Based on the hybridization of the privileged fragments in DABO and DAPY-typed HIV-1 NNRTIs, a novel series of 4-aminopiperidinyl-linked 3,5-disubstituted-1,2,6-thiadiazine-1,1-dione derivatives were designed, synthesized, and evaluated for their in vitro anti-HIV activities in MT-4 cells. Most of the target compounds showed weak inhibitory activity against WT HIV-1. In order to confirm the mode of action of the target compounds, representative ...
Design, synthesis, and anti-HIV evaluation of novel triazine derivatives targeting the entrance channel of the NNRTI binding pocket KU Leuven
A novel series of triazine derivatives targeting the entrance channel of the HIV-1 non-nucleoside reverse transcriptase inhibitor binding pocket (NNIBP) were designed and synthesized on the basis of our previous work. The results of a cell-based antiviral screening assay indicated that most compounds showed good-to-moderate activity against wild-type HIV-1 with EC50 values within the concentration range of 0.0078-0.16 μm (compound DCS-a4, EC50 ...
Tolerance of chemoorganotrophic bioleaching microorganisms to heavy metal and alkaline stresses KU Leuven
The bioleaching potential of the bacterium Bacillus mucilaginosus and the fungus Aspergillus niger towards industrial residues was investigated by assessing their response towards various heavy metals (including arsenic, cadmium, cobalt, chromium, nickel, lead and zinc) and elevated pH. The plate diffusion method was performed for each metal to determine the toxicity effect. Liquid batch cultures were set up for more quantitative evaluation as ...
