    Berberine Analogues as a Novel Class of the Low-Density-Lipoprotein Receptor Up-Regulators: Synthesis, Structure−Activity Relationships, and Cholesterol-Lowering Efficacy
    摘要:
    Twenty-nine derivatives of berberine (1) or pseudoberberine (2) were designed, semisynthesized, and evaluated for their up-regulatory activity on the low-density-lipoprotein receptor (LDLR) expression. SAR analysis revealed that (i) the methylenedioxy group at the 2- and 3-position is an essential element to keep the activity, (ii) the 7-position quaternary ammonium and planar structure of the compound are activity-required, and (iii) addition of electron-donating groups at the 7- or 13-position reduced the activity. Of the compound I analogues, compound 2 exhibited an increased activity on LDLR expression compared to 1. In the hyperlipidemic rats, compound 2 (100 (mg/kg)/day) reduced blood CHO and LDL-c by 42.6% and 49.4%, respectively, more efficient than I did (p < 0.01 for both). The results were confirmed in the hyperlipidemic mice. LD50 of 2 in mice was over 5000 mg/kg (oral). We consider compound 2 a promising cholesterol-lowering drug candidate.

    小檗碱衍生物作为 PCSK9 下调剂的构效关系和生物学评价
    摘要:
    前蛋白转化酶枯草杆菌蛋白酶 / kexin 9 型 (PCSK9) 是一种分泌蛋白,其缺乏可显着提高心血管疾病 (CVD) 患者的存活率。以小檗碱 (BBR) 为先导,合成了 40 种小檗碱 (BBR) 衍生物,并评估了它们下调 HepG2 细胞中 PCSK9 转录的活性。构效关系 (SAR) 分析表明 2,3-二甲氧基部分可能对活性有益。其中,9k的活性最强,IC 50值为9.5 ± 0.5 μM,优于BBR。此外,它在细胞水平以及体内小鼠的肝脏和血清中显着降低了 PCSK9 蛋白水平。此外,9k通过下调 PCSK9 蛋白显着增加 LDLR 表达和 LDL-C 清除。9k的作用机制是针对 PCSK9 上游的 HNF1α 和/或 Sp1 簇调制,这与 BBR 不同。因此,9k有可能成为治疗动脉粥样硬化的新型 PCSK9 转录抑制剂,值得进一步研究。

    and activates retinoid X receptor α (RXRα) for suppressing the growth of colon cancer cells. Here, we extended our studies based on the binding mode of Ber with RXRα by design, synthesis, and biological evaluation of a focused library of 15 novel Ber analogues. Among them, 3,9-dimethoxy-5,6-dihydroisoquinolino[3,2-a]isoquinolin-7-ium chloride (B-12) was identified as the optimal RXRα activator. More
    我们最近报道,小碱(Ber)是一种治疗肠胃炎的传统东方药物,结合并激活类视黄醇X受体α(RXRα)以抑制结肠癌细胞的生长。在这里,我们通过对15种新型Ber类似物的聚焦库的设计,合成和生物学评估,扩展了基于Ber与RXRα结合模式的研究。其中,3,9-二甲氧基-5,6-二氢异喹啉代[3,2- a ]异喹啉-7-氯化铵(B-12)被确定为最佳RXRα活化剂。的效率比误码率,B-12结合并改变RXRα/ LBD的构象,从而通过RXRα介导抑制Wnt /β-catenin途径和结肠癌细胞的生长。此外,B-12不仅保留了Ber的肿瘤选择性,而且大大提高了其生物利用度。值得注意的是,在小鼠中,B-12没有像其他RXRα激动剂那样显示出明显的副作用,包括高甘油三酯血症或诱发肝肾毒性。在一起,我们的研究描述了一种合理设计Ber衍生的RXRα激活剂作为结肠癌的新型有效抗肿瘤药的方法。

    Quaternary protoberberine alkaloids and quaternary benzophenanthridine alkaloids are two biosynthetically related natural product families of biological importance. Although significant advances have been achieved in the synthetic chemistry of these alkaloids, a unified approach to these tetracyclic pyridinium-contained alkaloids remains elusive until our recent report. Herein, we report a concise
