A small library of truncated/lipid-conjugated neuromedin U (NmU) analogs was synthesized and tested in vitro using an intracellular calcium signaling assay. The selected, most active analogs were then tested in vivo, and showed potent anorexigenic effects in a diet-induced obese (DIO) mouse model. The most promising compound, NM4-C16 was effective in a once-weekly-dose regimen. Collectively, our findings suggest that short, lipidated analogs of NmU are suitable leads for the development of novel anti-obesity therapeutics.
合成了一个由截短型/脂质缀合神经介素U(NmU)类似物组成的小型文库,并使用细胞内钙信号测定法在体外进行了测试。然后,对筛选出的活性最强的类似物进行了体内测试,结果显示其在饮食诱导肥胖(DIO)小鼠模型中具有显著的厌食作用。最有前景的化合物NM4-C16在每周一次给药方案中有效。总体而言,我们的研究结果表明,短链、脂质化的NmU类似物是开发新型抗肥胖疗法的合适先导物。
