ABSTRACT

The increasing incidence of inflammatory and malignant diseases signifies the need to develop first-in-class drugs with novel mechanisms of action. In this respect, the transforming growth factor (TGF)-β-activated kinase 1 (TAK1), an essential part of several signaling pathways, is considered relevant and promising. This manuscript provides a brief overview of the signal transduction orchestrated by TAK1 within these pathways, followed by an in-depth and thorough analysis of the chemical matter demonstrated to inhibit this kinase. Special attention is given to the selectivity profiling of inhibitors, as well as to the outcomes of their biological characterization. Because published TAK1 inhibitors differ significantly in their kinome selectivity, active-site binding, and biological activity, we hope that this review will allow a judicial estimation of their quality and usefulness for TAK1-addressing assays. Our thoughts on the perspectives and possible developments of the field are also provided to assist scientists who are involved in the design and development of TAK1-targeting modulators.
