  具有氟氯末端的立体定义烯烃作为独特的化合物类别

  摘要：

  三取代烯基氟化物是药物发现、农用化学品开发和材料科学的重要化合物。然而，尽管取得了显着进展，但许多立体化学定义的三取代氟烯烃要么无法有效制备，要么只能以一种异构形式获得。在这里，我们概述了这个问题的一般解决方案，首先揭示了一种实用的、广泛适用的催化策略，用于立体发散​​合成带有氟氯末端的烯烃。这是通过两种三取代烯烃之间的交叉复分解实现的，其中一种是可购买但几乎未被利用的三卤代烯烃。随后的交叉偶联可用于生成各种三取代的烯基氟化物。除其他外，综合强调了这一进展的重要性，E - 或Z - 酰胺键模拟物，以及二氟甲酸酯（一种抗癌化合物）的所有四种立体异构体。

  Synthesis and SAR studies of mono O-prenylated coumarins as potent 15-lipoxygenase inhibitors

  摘要：

  All of the mono isopentenyloxy, -geranyloxy and -farnesyloxy derivatives of coumarin were synthesized and their inhibitory potency against soybean 15-lipoxygenase (SLO) and human 15-lipoxygenase-1 (HLO-1) were determined. Amongst the synthetic analogs, 5-farnesyloxycoumarin showed the most potent inhibitory activity against SLO (IC50 = 0.8 mu M) while 6-farnesyloxycoumarin was the strongest HLO-1 inhibitor (IC50 = 1.3 mu M). The IC50 variations of the farnesyl derivatives for HLO-1 (1.3 to similar to 75 mu M) were much higher than that observed for SLO (0.8-5.8 mu M). SAR studies showed that hydrogen bonding, CH/pi, anion-pi and S-O=C interactions with Fe-III-OH, Leu408, Glu357 and Met419 were the distinct intermolecular interactions which can lead to important role of the coumarin substitution site in HLO-1 inhibitory potency, respectively.

  prenyloxy coumarins. The results showed that position and length of the prenyl moiety play the important role in lipoxygenase inhibitory activity. Among all of the synthetic compounds (coumarin and carbostyril derivatives), 5-farnesyloxycoumarin and 8-farnesyloxycarbostyril demonstrated the best inhibitory activity by IC50 values of 1.1 µM and 0.53 µM, respectively.

  动物和植物中不饱和脂质的催化过氧化与 15-脂氧合酶的活性密切相关。众所周知，脂氧合酶 (LOX) 在许多急性和慢性综合征中发挥着重要作用，例如炎症、哮喘、癌症和过敏。在本研究中，合成了一系列单异戊二烯氧基喹啉，并评估其作为大豆15-脂氧合酶（SLO）的潜在抑制剂，并将其抑制效力与先前报道的单异戊二烯氧基香豆素进行了比较。合成化合物通过竞争机制抑制脂氧合酶，如异戊二烯氧基香豆素。结果表明异戊烯基部分的位置和长度在脂氧合酶抑制活性中起着重要作用。在所有合成化合物（香豆素和喹诺酮衍生物）中，5-法呢基氧基香豆素和8-法呢基氧基喹诺酮表现出最佳的抑制活性，IC 50值分别为1.1 µM 和0.53 µM。

  Trisubstituted alkenyl fluorides are important compounds for drug discovery, agrochemical development and materials science. Despite notable progress, however, many stereochemically defined trisubstituted fluoroalkenes either cannot be prepared efficiently or can only be accessed in one isomeric form. Here we outline a general solution to this problem by first unveiling a practical, widely applicable
