Inhibitors of Nucleophilic Enzymes for therapeutic and drug discovery applications

These inhibitors are based on hydrazone derivatives produced using a novel synthetic route. The compounds react with the active site of nucleophilic enzyme, which typically have a nucleophile such as an amine, alcohol, or thiol on the side chain (for example - lysine, serine, and cysteine). In reacting at this site, the enzyme is inhibited. Such inhibition...

Antioxidants to preserve lipids

This technology targets free radicals, the molecules that cause substances to break down when they are exposed to ultraviolet light. The antioxidants are stable at room temperature or under mild heating, and do not turn brown over time as is seen with comparable antioxidants. The compounds would be a suitable replacement for BHT and tocopherol in fine...

Efficient synthesis of synthetic peptides containing beta-aminocarbonyls

Beta-aminocarbonyls are found in several major drugs and are increasingly important in synthetic peptides. This method reduces the cost of synthesizing beta-aminocarbonyl structures by reducing the number of steps in the synthesis, and using low cost starting reagents. It can also be easily scaled from the bench to the manufacturing process.
