Since the development of the first protein kinase inhibitor in the early 1980s, followed by the FDA approval of imatinib in 2001, kinases are one of the most intensively pursued targets in current medicinal chemistry research. These proteins are overrepresented in various diseases such as cancer, inflammation or autoimmune pathologies and play important roles in their physiopathogenic processes. Despite the development and approval of numerous potent kinase inhibitors, drug resistance and off‐target side effects are commonly encountered with kinase inhibitors. Thus, development of novel strategies to overcome these problems is necessary. Since 2013, many research groups have proposed the conversion of potent kinase inhibitors into PROteolysis TArgeting Chimera (PROTAC) compounds and shared relevant and encouraging results using this new technology, which degrades proteins by employing the cellular machinery. Generally, this strategy brings enhancements in biological effects compared to the use of only the parent inhibitor. In this review article, recent findings related to the PROTAC technology applied to kinases are discussed, with a special focus on publications since 2018.
