    为了寻找具有更好生物活性的新型原卟啉原氧化酶(PPO)抑制剂,基于亚结构剪接和生物异构化的原理,设计了一系列新型的含有四氢邻苯二甲酰亚胺的二苯醚衍生物。PPO抑制实验显示6c是最有潜力的化合物,其半数最大抑制浓度(IC50)值为0.00667 mg / L,显示出比抗氧氟芬(IC50 = 0.0426 mg / L)高7倍的抗玉米PPO活性和类似的除草活性在温室除草实验和田间除草实验中使用Oxyfluorfen。鉴于所检查的生物活性,还讨论了该系列化合物的结构-活性关系(SAR)。作物选择实验表明,化合物6c对于大豆,玉米,大米,花生和棉花的剂量为300 g ai / ha。积累分析实验表明,某些作物(大豆,花生和棉花)中6c的积累显着低于Oxyfluorfen。当前的工作表明化合物6c可以作为田间除草剂的新候选物开发。

  • Activation and Inhibition of Kidney CLC-K Chloride Channels by Fenamates
    作者:Antonella Liantonio、Alessandra Picollo、Elena Babini、Giuseppe Carbonara、Giuseppe Fracchiolla、Fulvio Loiodice、Vincenzo Tortorella、Michael Pusch、Diana Conte Camerino

    CLC-K Cl– channels are selectively expressed in kidney and ear, where they are pivotal for salt homeostasis, and loss-of-function mutations of CLC-Kb produce Bartter's syndrome type III. The only ligand known for CLC-K channels is a derivative of the 2- p -chlorophenoxypropionic acid (CPP), 3-phenyl-CPP, which blocks CLC-Ka, but not CLC-Kb. Here we show that in addition to this blocking site, CLC-K channels bear an activating binding site that controls channel opening. Using the voltage-clamp technique on channels expressed in Xenopus laevis oocytes, we found that niflumic acid (NFA) increases CLC-Ka and CLC-Kb currents in the 10 to 1000 μM range. Flufenamic acid (FFA) derivatives or high doses of NFA produced instead an inhibitory effect on CLC-Ka, but not on CLC-Kb, and on blocker-insensitive CLC-Ka mutants, indicating that the activating binding site is distinct from the blocker site. Evaluation of the sensitivity of CLC-Ka to derivatives of NFA and FFA together with a modeling study of these ligands allow us to conclude that one major characteristic of activating compounds is the coplanarity of the two rings of the molecules, whereas block requires a noncoplanar configuration. These molecules provide a starting point for identification of diuretics or drugs useful in the treatment of Bartter's syndrome.
    CLC-K Cl– 渠道在肾脏和耳朵中特异性表达,它们对盐的稳态至关重要,CLC-Kb 的功能缺失突变可导致 III 型巴特综合征。目前已知的 CLC-K 渠道唯一配体是 2- p -氯苯丙酸 (CPP) 的衍生物 3-苯基-CPP,它可以阻断 CLC-Ka,但不影响 CLC-Kb。在这里,我们展示了除了该阻断位点外,CLC-K 渠道还具有一个激活结合位点,该位点控制通道的开启。通过对表达在非洲爪蛙卵母细胞中的通道使用电压夹持技术,我们发现辛酸 (NFA) 在 10 至 1000 μM 范围内增加了 CLC-Ka 和 CLC-Kb 的电流。芬那酸 (FFA) 的衍生物或高剂量的 NFA 对 CLC-Ka 产生了抑制作用,而对 CLC-Kb 则没有,并且在对阻断剂不敏感的 CLC-Ka 突变体上同样显示出该作用,表明激活结合位点与阻断位点是不同的。对 CLC-Ka 对 NFA 和 FFA 衍生物的敏感性评估,以及对这些配体的建模研究,让我们得出结论:激活化合物的一个主要特征是分子两个环的共平面性,而阻断则需要非共平面构型。这些分子为识别利尿剂或在治疗巴特综合征方面有用的药物提供了起点。
