Inhibition of the differentiation of adipocytes and reduced lipid synthesis are efficacious approaches for treating obesity-related metabolic disorders. Bouchardatine (Bou) is a natural alkaloid that has been reported to moderately inhibit the differentiation of 3T3-L1 cells without inducing toxicity. To explore the importance of aldehyde group at 8a-position of Bou and optimize the activity, we synthesized
抑制脂肪细胞的分化和减少脂质的合成是治疗肥胖相关的代谢性疾病的有效方法。Bouchardatine(Bou)是一种天然生物碱,据报道可适度抑制3T3-L1细胞的分化而不会引起毒性。为了探索在Bou的8位a位置醛基的重要性并优化活性,我们通过丢弃或用卤素取代醛基并在Bou的5位置处引入不同的胺链,合成了35种(31种新型)化合物。使用基于细胞的筛选系统评估了降脂活性。小组在8 a的替换化合物的位置对降低脂质的活性很重要,并讨论了SAR。选择性化合物6e中显示出它的降脂作用的93倍增加(EC 50 相比= 0.24μM)和尚(EC 50 ≈25μM)。进一步的机理研究表明,化合物6e激活了AMP激活的蛋白激酶(AMPK)通路,并抑制MCE活性以阻止细胞增殖并诱导分化早期的细胞周期停滞,从而降低了脂肪形成因子的表达和脂肪酸合成相关蛋白质。
