Current clinical research suggests that fatty acid‐binding protein 4 inhibitors (FABP4is), which are of biological and therapeutic interest, may show potential in treating cancer and other illnesses. We sought to uncover new structures through the optimization of the previously reported 4‐amino and 4‐ureido pyridazinone‐based series of FABP4is as part of a larger research effort to create more potent FABP4 inhibitors. This led to the identification of
