Cysteine is present in a large number of natural and synthetic (bio)molecules. Although the thiol side chain of Cys can be in a free form, in most cases it forms a disulfide bond either with a second Cys (bridge) or with another thiol, as in the case of protecting groups. Efficient reduction of these disulfide bridges is a requirement ...
WebApr 11, 2024 · 17c, with the p-OMe group, seemed to be a better inhibitor than 15c or 16c because the O of the OMe group hydrogen bonds to the side chain of a glutamine residue. The in silico studies also suggested that the selectivity of 15 – 17 for PDHc E1 is because the longer side-chains are too bulky to be accommodated in the smaller diphosphate … WebHarvard Web Publishing
