Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt
British Journal of Pharmacology, EarlyView.Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the
