48 new drugs including 38 chemical entities (33 new chemical entities, 3 new diagnostic agents, and 2 payloads of antibody drug conjugates) and 10 biologics were approved by the U.S. Food and Drug Administration (FDA) during 2019. These marketed new drugs represent privileged structures and novel action of mechanism, and thus can be served as leads to discover new drugs with the similar biological targets and improved therapeutic efficacy. This review aims to provide an overview regarding the synthetic approaches of 33 new chemical entities approved by the FDA in 2019 and their clinical applications.
