Discovery and Optimization of wt-RET/KDR-Selective Inhibitors of RETV804M Kinase

A combination of focused library and virtual screening, hit expansion, and rational design has resulted in the development of a series of inhibitors of RETV804M kinase, the anticipated drug-resistant mutant of RET kinase. These agents do not inhibit the wild type (wt) isoforms of RET or KDR and therefore offer a potential adjunct to RET inhibitors currently undergoing clinical evaluation
