N-hydroxysuccinimide (NHS) esters belong to the group of amine-reactive active esters and are thus of great use in labeling proteins Typically NHS esters react with the primary amino group in the side chain of surficial lysine forming a stable peptide bond (Figure 1) The utility of NHS esters was first suggested by Anderson et al in the context of peptide synthesis nowadays a plethora of

Introduction to Sulfur Functional Groups

It is less toxic than other members of this class such as dimethylformamide dimethylacetamide N-methyl-2-pyrrolidone HMPA Because of its excellent solvating power DMSO is frequently used as solvent for chemical reactions involving the reactions of salts Because DMSO is only weakly acidic it tolerates relatively strong bases The main problem with DMSO as a solvent is its high boiling

Chronic Treatment With a Melanocortin

The melanocortin-4 receptor (MC4R) is well recognized as an important mediator of body weight homeostasis Activation of MC4R causes dramatic weight loss in rodent models and mutations in human are associated with obesity This makes MC4R a logical target for pharmacological therapy for the treatment of obesity However previous studies in rodents and humans have observed a broad array
