  Resolution, absolute configuration and antifilarial activity of coumarinyl amino alcohols

  摘要：

  The resolution of racemic coumarinyl amino alcohols 5-10 was achieved by using the inexpensive and readily accessible chiral resolving agent N-carbethoxy-L-proline (S)-11. Direct esterification of rac-5-10 with (S)-11 furnished diastereomeric esters, which were easily separated by column chromatography. The obtained diastereomers yielded the desired enantiopure coumarinyl amino alcohols (S)-(+)-5-10 and (R)-(-)-5-10 in good yields with high enantiomeric excess on saponification. The absolute configurations were determined by X-ray crystal analysis and/or by comparison of the specific rotations. Furthermore, in in vitro antifilarial motility inhibition assays, enantiopure coumarins (S)-(+)-9, (R)-(-)-9 and (S)-(+)-10, (R)-(-)-10 were found to be less efficient in affecting the viability of macrofilariae of Brugia malayi than their racemic forms 9 and 10, respectively, indicating the synergistic effect of the enantiomers in evoking antifilarial action.

  新型香豆素-靛红杂种作为有效的抗利什曼病药物：合成、计算机模拟和体外评估

  摘要：

  利什曼病是每年影响近 0.7 至 130 万人的六种主要热带疾病之一，迄今为止治疗选择有限且毒性高。在此，我们报告了新型香豆素结合靛红腙 ( Spf-1 – Spf-10 ) 作为高效和安全的抗利什曼病药物的合成、计算机和体外评估。最初进行分子对接以破译先导分子与热带利什曼原虫( Leishmania tropica ) 靶蛋白 (利什曼原虫溶血素 gp63) 的活性腔的结合确认。在所有停靠的化合物中，只有Spf-6、Spf-8和Spf-10由于强常规氢键和疏水 π 相互作用的模式，显示出高结合亲和力。分子动力学模拟显示了这种键合的稳定模式和基于结构的确认，时间尺度为 50 ns，朝向顶部化合物 ( Spf-10 ) 和蛋白质。这些分析肯定了系统的高稳定性。发现十分之三的化合物对热带利什曼原虫前鞭毛体和无鞭毛体的抗利什曼原虫活性进行了评估，发现在微摩尔浓度（IC 50范围为 0.1 – 4

  In a search for the inhibitors of platelet aggregation, certain coumarin derivatives were synthesized and evaluated for antiplatelet activity against thrombin(Thr)-, arachidonic acid(AA)-, collagen(Col)-, and platelet-activating-factor(PAF)-induced aggregation in washed rabbit platelets. These compounds were synthesized from 4-hydroxycoumarin (1) or naphthalen-1-ol via alkylation and Reformatsky-type

  A regioselective and concomitant transfer of thiocyanate (−SCN) and aroyl/acyl (−COR) groups from aroyl/acyl isothiocyanates onto oxiranes was achieved, giving thiocyanato benzoates in 100% atom economy. In this biomimetic organocatalytic process, one part (−SCN) of aroyl/acyl isothiocyanates acts as the nucleophile whereas the other half (−COR) serves as an electrophilic partner.

  A series of 4-oxycoumarin derivatives was synthesized, characterized and evaluated in vitro and in vivo for antifilarial activity against the human lymphatic filarial parasite, Brugia malayi. A majority of the compounds studied showed potent in vitro activity with low IC50 values in the micro molar (mu M) range (0.014-1.73 and 0.0056-0.43) against adult worms and microfilariae, respectively. Compounds 8 and 9 were identified to be the most promising antifilarial candidate molecules exhibiting activity in the nanomolar (nM) range. The IC50 values for compound 8 were 14 nM and 5.6 nM while for compound 9 were 94 nM and 13 nM, respectively, for adult worm and microfilaria. These two compounds also displayed promising adulticidal activity (74.9 +/- 4.8% and 69.4 +/- 2.8%, respectively) in the primary rodent (jird) screen. This study also serves as a starting point for investigating structure-activity relationship with different amino substituents. (C) 2015 Elsevier Masson SAS. All rights reserved.
