Click chemistry patents and their impact on drug discovery and chemical biology

摘要

First introduced by K Barry Sharpless in 2001, the term 'click chemistry' soon became a widely used description of chemical reactions that proceed rapidly, cleanly and in a manner that is often compatible with aqueous solutions. Click chemistry is frequently employed throughout the process of drug discovery, and greatly helps advance research programs in the pharmaceutical industry. It facilitates library synthesis to support medicinal chemistry optimization, helps identify the targets and off-targets of drug candidates, and can facilitate the determination of drug efficacy in clinical trials. In the last decade, a large number of patent applications covering the various types and utilities of click chemistry have been filed. In this review, we provide the first analysis of click chemistry applications.
