Combining a GPR34 antagonist with chemotherapy and surufatinib significantly enhanced anti-tumor responses in preclinical models. These findings identify GPR34 as a promising immune therapeutic target.
Guided by a scaffold-hopping strategy based on G-749 (denfivontinib), a series of quinazoline-based derivatives was designed and synthesized to explore structure-activity relationships (SAR)...Mechanism studies indicated that W4 induced G0/G1 cell cycle arrest and apoptosis, accompanied by a reduction in intracellular reactive oxygen species levels and a loss of mitochondrial membrane potential. Collectively, these results identified W4 as a potent FLT3 inhibitor and provided valuable SAR insights for further scaffold optimization.
