    由1,1,1-三氟-4-甲氧基-3-烯丙基-2-酮与4-肼基-7-氯喹啉反应合成的氯喹吡唑类似物的抗疟活性已在体外针对氯喹进行了评估。抗性恶性疟原虫克隆。与没有药物的对照相比,通过掺入[(3)H]次黄嘌呤来测量存在试验药物的寄生虫的生长。测试的八种(4,5-二氢吡唑-1-基)氯喹2衍生物中,除一种化合物外,其他化合物均在体外具有显着活性,因此是一类有前途的新型抗疟药。还在小鼠中对三种活性最强的伯氏疟原虫进行了体内测试。然而,(吡唑-1-基)氯喹3衍生物大部分是无活性的,这表明吡唑环的芳族官能度是关键的。

  • One-Pot Synthesis of Functionalized 3-(Trifluoromethyl)phenols by [3+3] Cyclization of 1,3-Bis(silyl enol ethers) with α,β-Unsaturated Trifluoromethyl Ketones

    Functionalized 3-(trifluoromethyl)phenols were prepared by formal [3+3] cyclization of 1,3-bis(silyl enol ethers) with readily available open-chained and cyclic α,β-unsaturated trifluoromethyl ketones. The reaction of 3,4-dihydro-5-(trifluoroacetyl)-2H-pyran with 1,3-bis(silyl enol ethers) resulted in a domino process to give new functionalized dihydropyrans. (© Wiley-VCH Verlag GmbH & Co.

  • ClickEnam. 1. Synthesis of novel 1,4-disubsituted-[1,2,3]-triazole-derived β-aminovinyl trifluoromethylated ketones and their copper(II) complexes
    作者:Nicolas Chopin、Sophie Decamps、Aude Gouger、Maurice Médebielle、Stéphane Picot、Anne-Lise Bienvenu、Guillaume Pilet

    日期:2011.10
    The copper(I) catalyzed cycloaddition reaction of N-Boc propargyl amine (dipolarophile) 1 with benzyl azide (1,3-dipole) 2 was found to proceed smoothly in t-BuOH/H2O at room temperature, to furnish the corresponding 1,4-disubstituted-[1,2,3]-triazole-derived N-Boc amine 3 in good yield. Deprotection of 3 with trifluoroacetic acid and addition of the trifluoroacetate salt 4 in the presence of triethylamine, with a series of methoxyvinyl(trifluoromethyl)ketones 10-14, gave the corresponding beta-aminovinyl trifluormethylated ketones 15-19 in moderate to good yields. Two copper(II) complexes, one monomer and one dimer with chlorine double bridge, 20 and 21, respectively, were also prepared and their crystal structure determined. beta-Aminovinyl trifluoromethylated ketones 15-17 and complexes 20 and 21 have been screened as potential antifungal agents and the antimalarial activity of 15 and 16 were tested against two Plasmodium falciparum strains (3D7 and W2).

  • Antimalarial activity of 4-(5-trifluoromethyl-1H-pyrazol-1-yl)-chloroquine analogues

    the eight (4,5-dihydropyrazol-1-yl) chloroquine 2 derivatives tested showed a significant activity in vitro, thus, are a promising new class of antimalarials. The three most active ones were also tested in vivo against Plasmodium berghei in mice. However, the (pyrazol-1-yl) chloroquine 3 derivatives were mostly inactive, suggesting that the aromatic functionality of the pyrazole ring was critical.
