WebJan 1, 2009 · A trapping approach for semi-quantitative assessment of bioactivation potential has been established for new chemical entities by using [ 35 S]cysteine and [ 14 C]sodium cyanide as trapping reagents. Reactive metabolites were trapped as radioactive adducts with the trapping reagents to be analyzed by radio-LC (/MS). WebOct 1, 2024 · Viability assays, cysteine-trapping, and most of the electrophysiological recordings were performed in MJF465, and gating thresholds were determined in MJF429. E. coli strain DH10β was used for site-directed mutagenesis. All strains were stored in glycerol stock solution (65% glycerol, 0.1 M MgSO 4, 0.025 M Tris-Cl) at -80°C. The …

WebWe found that cysteine is a good trapping agent and developed an assay method for the reactivity of acyl CoA metabolites. We evaluated 17 drugs with carboxylic acid moieties, all drugs concerned with hepatotoxicity displayed reactive potential. Webcysteine can readily react during gene expression (e.g. pyru-vate) limiting the potential FPBA labeling reaction.30,55–59 ... a chemo-enzymatic approach that incorporates N-terminal cysteine trapping by for-mylphenyl boronic acid (FPBA) was reported. (Inset) Crystal structure overlay of the active sites of OaAEP1 (orange, 5H0I) and butelase 1 ... WebMay 2, 2012 · Both the cysteine trap mutant TACE and TACE-B showed a comparatively low extent of activation in response to PMA. These data suggest that dimer dissociation, which is prevented in the cysteine trap TACE mutant, has an important role in increasing TACE activity in response to ERK or p38 MAPK signaling. portfolio recovery careers
