  粉防己碱的简化衍生物作为有效且特异性的 P-gp 抑制剂，可逆转癌症化疗中的多药耐药性

  摘要：

  靶向抑制药物外排转运蛋白 P-糖蛋白 (P-gp) 是逆转癌症化疗中多药耐药性的重要策略。本研究基于分子动力学模拟和片段生长对天然粉防己碱进行了合理的结构简化，得到了一种易于制备、新颖且简化的化合物OY-101，具有高逆转活性和低细胞毒性。通过逆转活性测定、流式细胞术、平板克隆形成测定和药物协同分析证实其与长春新碱（VCR）对耐药细胞Eca109/VCR具有优异的协同抗癌作用（IC 50 = 9.9 nM，RF = 690） 。进一步的机制研究证实OY-101是一种特异性、高效的P-gp抑制剂。重要的是，OY-101增加了体内VCR 致敏性，但没有明显的毒性。总体而言，我们的研究结果可能为设计新型特异性 P-gp 抑制剂作为抗肿瘤化疗增敏剂提供替代策略。

• Total Synthesis of (<i>S</i>,<i>S</i>)-Tetramethylmagnolamine via Aerobic Desymmetrization
  作者：Zheng Huang、Xiang Ji、Jean-Philip Lumb

  We describe a concise synthesis of the pseudodimeric tetrahydroisoqunoline alkaloid (S,S)-tetramethylmagnolamine by a catalytic aerobic desymmetrization of phenols. Desymmetrization reactions increase molecular complexity with high levels of efficiency, but those that do so by aerobic oxidation are uncommon. Our conditions employ molecular oxygen as an oxygen atom transfer agent and a formal acceptor

  我们描述了通过苯酚的催化好氧脱对称化的伪二聚体四氢异喹啉生物碱（S，S）-四甲基木酚胺的简洁合成。脱对称反应以高水平的效率增加了分子的复杂性，但是通过有氧氧化进行脱对称反应的情况并不常见。我们的条件使用分子氧作为氧原子转移剂和氢的形式受体，从而实现了两个机械上截然不同的芳族CH氧化反应，并具有很高的选择性。
• Effect of 1-Substitution on Tetrahydroisoquinolines as Selective Antagonists for the Orexin-1 Receptor

  Selective blockade of the orexin-1 receptor (OX1) has been suggested as a potential approach to drug addiction therapy because of its role in modulating the brain's reward system. We have recently reported a series of tetrahydroisoquinoline-based OX1 selective antagonists. Aimed at elucidating structure-activity relationship requirements in other regions of the molecule and further enhancing OX1 potency and selectivity, we have designed and synthesized a series of analogues bearing a variety of substituents at the 1-position of the tetrahydroisoquinoline. The results show that an optimally substituted benzyl group is required for activity at the OX1 receptor. Several compounds with improved potency and/or selectivity have been identified. When combined with structural modifications that were previously found to improve selectivity, we have identified compound 73 (RTIOX-251) with an apparent dissociation constant (K-e) of 16.1 nM at the OX1 receptor and >620-fold selectivity over the OX2 receptor. In vivo, compound 73 was shown to block the development of locomotor sensitization to cocaine in rats.
• Simplified Tetrandrine Congeners as Possible Antihypertensive Agents with a Dual Mechanism of Action

  A series of O- and/or N-substituted derivatives of (+/-)-coclaurine (1a) were synthesized as simplified structural mimics of the antihypertensive alkaloid tetrandrine (2) and assayed for binding to brain cortical sites labeled with the alpha(1)-adrenergic radioligand [H-3]prazosin or the calcium channel radioligand [H-3]-diltiazem. The introduction of O-benzyl groups on the coclaurine molecule, which exhibits only adrenergic antagonist activity, led to the appearance of calcium channel blocking activity comparable to that of tetrandrine while retaining adrenolytic activity in the same concentration range. Contraction of aortal rings with noradrenaline or KCl was relaxed more potently by some of these coclaurine derivatives than by tetrandrine, suggesting leads for the development of novel antihypertensive drugs with a dual mechanism of action.

  Targeted inhibition of a drug efflux transporter P-glycoprotein (P-gp) is an important strategy to reverse multidrug resistance in cancer chemotherapy. In this study, a rationally structural simplification to natural tetrandrine was performed based on molecular dynamics simulation and fragment growth, leading to an easily prepared, novel, and simplified compound OY-101 with high reversal activity and
