[Boronic Acid as a Promising Class of Chemical Entity for Development of Clinical Medicine for Targeted Therapy of Cancer].

Abstract

The first medicine containing the boron element, bortezomib, was approved for clinical use just 18 years ago. The boronic acid substructure in bortezomib serves as an electrophilic functionality with high affinity for hydroxy groups, which are frequently found in catalytic sites of proteolytic enzymes, to create reversible covalent bonds with a slow dissociation rate. Today, boronic acid is considered an important molecule in the medicinal chemistry toolbox, which was promoted by the success of bortezomib and pioneering approaches to use boronic acid in the molecular design of serine protease inhibitors in the 1980s. In this review article, we first provide an overview of the development of bortezomib, and then summarize our achievements to construct boronic acid analogs of tyropeptin A, a naturally occurring proteasome inhibitor, with potent in vivo efficacy. Representative stereoselective synthetic methods of α-aminoboronic acid are also showcased.
