  天然和合成 Prodiginines 的抗疟活性

  摘要：

  Prodiginines 是一系列线性和环状低聚吡咯红色颜料化合物。在此，我们描述了四种天然 (IC 50 = 1.7–8.0 nM) 和三组合成 prodiginine 对恶性疟原虫的体外抗疟活性。第 1 组化合物取代了天然 prodiginines 的末端非烷基化吡咯环并且活性降低 (IC 50 > 2920 nM)。第 2 组和第 3 组 prodiginine 分别在右手端吡咯的 3 或 5 位被单取代或双取代。使用烷基或芳基取代基观察到有效的体外活性 (IC 50 = 0.9–16.0 nM)。在P. yoelii中评估了 Metacycloprodiginine 和更有效的合成类似物使用口服给药的鼠专利感染。每种类似物在每天 25 (mg/kg) 给药后将寄生虫血症降低了 90% 以上，并且在某些情况下可以治愈。最有利的特征是 5 (mg/kg)/天的寄生虫减少 92%，25 (mg/kg)/天的寄生虫减少

• Asymmetric synthesis of new chiral long chain alcohols

  Sixteen new chiral alcohols with alkyl (C-11-C-19) and aryl, substituted aryl, hetero aryl and biaryl groups 2a-2t were synthesized by three different asymmetric reduction methods from their corresponding ketones 1a-1t. Chiral NaBH4 (method A), chiral BH3 (method B) and chiral AIP (method C) were used as asymmetric reduction catalysts. Chiral NaBH4 was modified by four different ligands 3a-3d, chiral BH3 and chiral AIP by four different ligands 4a-4d. Ligand 4c was synthesized for the first time in this work. Chiral NaBH4 generated chiral alcohols of (R)-configuration and chiral BH3 and chiral AIP of (S)-configuration with high enantiomeric excesses, were analysed by chiral HPLC. In order to determine the ee values by chiral HPLC, sixteen corresponding racemic alcohols, synthesized by reducing their corresponding ketones via NaBH4, were used for chiral resolution on a Daicel OD HPLC column. The sixteen starting ketones were synthesized in this study by Friedel-Craft acylation. The new chiral alcohols were characterized by IR, NMR, (H-1 and C-13), MS, elemental analyses and specific rotation. The reduction methods A, B and C were applied to these ketones for the first time in this study and were compared with each other. The relationship between the structure of the ketone and the yield and the enantiomeric excess was discussed. (C) 2010 Elsevier Ltd. All rights reserved.
