    摘要:
    一类新化合物,包含两系列查耳酮,分别带有2,2,2-三氟乙氧基和2-氟乙氧基,被合成并在体外针对恶性疟原虫(3D7株)进行了抗疟活性筛选,采用[3H]次黄嘌呤掺入抑制试验。在1-苯环的p-和m-位上带有2,2,2-三氟乙氧基的查耳酮显示出较弱的抗疟活性,而在1-苯环的o-位上带有该基团的化合物则展现出增强的抗疟活性,表明在查耳酮的1-苯环上的2,2,2-三氟乙氧基具有位点依赖性的抗疟活性。在合成的34个化合物中,查耳酮3a和3f表现出显著的抑制效果,IC50值分别为3.0 μg/mL和2.2 μg/mL。此外,化合物3a和3f与青蒿素在体外联合应用时显示出深刻的抗疟活性。活性最强的分子3a和3f,对其在哺乳动物Vero细胞上的细胞毒性进行了评估,选择性指数(SI)值分别为8.6和8.2,被认为无毒。我们还研究了2-氟乙氧基查耳酮的抗疟活性,以了解氟乙氧基中氟原子数量的影响。结果显示,1-苯环上带有2-氟乙氧基的查耳酮对寄生虫生长的抑制效果比其三氟类似物更为增强,表明单氟乙氧基在抑制寄生虫生长方面通常比三氟乙氧基更有效。因此,o-2,2,2-三氟乙氧基查耳酮(系列3)和2-氟乙氧基查耳酮可能是未来进一步开发的优秀抗疟候选药物。

    2-trifluoroethoxylation of activated aryl bromides and bromo-chalcones has been developed. We unveil a fascinating insight into the Pd-catalyzed C–O cross-coupling reaction. Pd/tBuXPhos (L1) ligand system facilitates the C–O cross-coupling reaction between 2,2,2-trifluoroethanol and activated aryl bromides at both higher (115 °C) and lower temperatures (40 °C). Unprecedentedly, this catalyst system facilitates the

    An efficient unprecedented Pd-catalyzed rapid 2-fluoroethoxylation of bromo-chalcones has been unveiled. The oxygen nucleophiles (fluoroalcohols) experience the rapid C-O bond forming reaction for the first time, albeit the alcohols are known to be a weak nucleophile and have greater competing beta-hydride elimination in the transition-metal-catalyzed (especially Pd and Cu) C-O cross-coupling reaction. The higher fluoroalcohols have also been effectively coupled with bromo-chalcones with relatively lower rate. (C) 2016 Elsevier B.V. All rights reserved.

    A new class of compounds comprising two series of chalcones with 2,2,2-trifluoroethoxy group and 2-fluoroethoxy groups were synthesized and screened for in vitro antiplasmodial activity against Plasmodium falciparum (3D7) using the [3H] hypoxanthine incorporation inhibition assay. Chalcones with 2,2,2-trifluoroethoxy groups substituted on the p- and m-positions of the 1-phenyl ring showed weak antiplasmodial activity, while compounds substituted on the o-position of the 1-phenyl ring displayed enhanced antiplasmodial activity, thus indicating that 2,2,2-trifluoroethoxy groups on the 1-phenyl ring of chalcones show position-dependent antiplasmodial activity. Of the 34 compounds synthesized, chalcones 3a and 3f exhibited significant inhibitory effects, with IC50 values of 3.0 μg/mL and 2.2 μg/mL, respectively. Moreover, these compounds 3a and 3f showed profound antiplasmodial activity in combination with artemisinin in vitro. The most active molecules, 3a, and 3f, were further assessed for their cytotoxicity towards mammalian Vero cells and the selectivity index (SI) values are 8.6, and 8.2 respectively, being considered non-toxic. We also studied the antiplasmodial activity of 2-fluoroethoxychalcones to discern the effect of the number of fluorine atoms in the fluoroethoxy group. Our results showed that chalcones with 2-fluoroethoxy group on the 1-phenyl ring exhibited more enhanced inhibitory effects on the growth of parasites than their trifluoro analogues, which reveals that monofluoroethoxy group is generally more effective than trifluoroethoxy group in the inhibition of parasite growth. Thus o-2,2,2-trifluoroethoxychalcones (Series 3) and 2-fluoroethoxychalcones may serve as good antiplasmodial candidates for future further development.
