An updated patent review of antitumor macrocyclic kinase inhibitors (2019 present)

Introduction Small molecule kinase inhibitors are crucial in the treatment of tumors, and the development of novel inhibitors is a primary approach to combat the continuous emergence of drug resistance. Macrocyclization has emerged as a cutting-edge strategy to enhance the potency, selectivity, and pharmacokinetic properties of these inhibitors by altering their biological and physicochemical characteristics compared to their acyclic counterparts.
