  Structural determinants for histamine H1 affinity, hERG affinity and QTc prolongation in a series of terfenadine analogs

  摘要：

  In the late 1980's reports linking the non-sedating antihistamines terfenadine and astemizole with torsades de pointes, a form of ventricular tachyarrhythmia that can degenerate into ventricular fibrillation and sudden death, appeared in the clinical literature. A substantial body of evidence demonstrates that the arrhythmogenic effect of these cardiotoxic antihistamines, as well as a number of structurally related compounds, results from prolongation of the QT interval due to suppression of specific delayed rectifier ventricular K+ currents via blockade of the hERG-IKr channel. In order to better understand the structural requirements for hERG and H-1 binding for terfenadine, a series of analogs of terfenadine has been prepared and studied in both in vitro and in vivo hERG and H-1 assays.

  precursor/loading and the ratio of Metal/Ligand/Cyclodextrin were also investigated. The addition of cyclodextrins as a mass transfer agent remarkably increased the rate reaction and the selectivity of linear amines, specially in the case of RAME-β-CD. So, the Rh/TPPTS/RAME-β-CD as a catalyst exhibited high conversion (92%) and selectivity (79.2%) towards the linear amine as major product under mild conditions

  这项工作报道了在水性介质中丁香酚，茴香脑和雌蕊具有哌啶的高度区域选择性氢氨基甲基化。该催化体系由通过三磺化三苯膦（TPPTS）稳定的铑配合物和天然或化学修饰的环糊精组成。各种环糊精，例如α-环糊精（α-CD），β-环糊精（β -CD），γ-环糊精（γ -CD），2-羟丙基β-环糊精（hp- β -CD）和随机甲基化的β -环糊精（RAME- β-CD）已经过测试。还研究了不同参数的影响，例如合成气压力，时间，温度，催化剂前体/负载量以及金属/配体/环糊精的比例。特别是在RAME-β-CD的情况下，加入环糊精作为传质剂显着提高了速率反应和线性胺的选择性。因此，在温和条件下，作为催化剂的Rh / TPPTS /RAME-β-CD表现出较高的转化率（92％）和对线性胺的选择性（79.2％）。最终，催化体系被循环使用了五次，而活性和选择性没有明显损失。
