AbstractCurrent 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 14e as the most potent analog with IC50 = 1.57 μM, which is lower than the IC50 of the positive control. Advanced modeling investigations and in silico absorption, distribution, metabolism, and excretion ‐ toxicity calculations suggested that 14e represents a potential candidate for in vivo studies such as FABP4i.
摘要目前的临床研究表明,脂肪酸结合蛋白 4 抑制剂(FABP4is)具有生物学和治疗学意义,可能在治疗癌症和其他疾病方面显示出潜力。我们试图通过优化以前报道过的基于 4-氨基和 4-脲基哒嗪酮的 FABP4is 系列来发现新的结构,作为创造更有效的 FABP4 抑制剂的更大研究努力的一部分。结果发现 14e 是最有效的类似物,其 IC50 = 1.57 μM,低于阳性对照的 IC50。先进的建模研究和硅学吸收、分布、代谢和排泄-毒性计算表明,14e 是 FABP4i 等体内研究的潜在候选药物。
