  Synthesis, in Vitro Antimycobacterial and Antibacterial Evaluation of IMB-070593 Derivatives Containing a Substituted Benzyloxime Moiety

  摘要：

  合成并评价了一系列含有取代苯甲酰肟基团且脂溶性显著提高的新型IMB-070593衍生物的体外抗分枝杆菌和抗菌活性。我们的结果显示，目标化合物19a–m对革兰氏阳性菌具有相当高的活性（MIC：<0.008–32 µg/mL），尽管它们对革兰氏阴性菌的活性通常低于参考药物。特别是化合物19h、19j、19k和19m对所有测试的革兰氏阳性菌株显示出良好的活性（MICs：<0.008–4 µg/mL），包括对环丙沙星（CPFX）和/或左氧氟沙星（LVFX）耐药的甲氧西林敏感金黄色葡萄球菌（MSSA）、甲氧西林耐药金黄色葡萄球菌（MRSA）和表皮葡萄球菌（MSSE）。此外，化合物19l（MIC：0.125 µg/mL）对抗ATCC 27294的结核杆菌H37Rv的活性是母体化合物IMB070593、环丙沙星和左氧氟沙星的2–4倍。

  Design, synthesis and antifungal activities of novel pyrrole alkaloid analogs

  摘要：

  A series of novel analogs of pyrrole alkaloid were designed and synthesized by a facile method and their structures were characterized by H-1 NMR, C-13 NMR and high-resolution mass spectrometry (HRMS). The structure of compound 2a was identified by 2D NMR including heteronuclear multiple-quantum coherence (HMQC), heteronuclear multiple-bond correlation (HMBC) and H-H correlation spectrometry (H-H COSY) spectra. Their antifungal activities against five fungi were evaluated, and the results indicated that some of the title compounds showed moderate fungicidal activities in vitro against Alternaria solani, Cercospora arachidicola, Fusarium omysporum, Gibberella zeae and Physalospora piricola at the dosage of 50 mu g mL(-1). Compound 2a and 3a exhibited good activities against P. piricola at low dosage. (C) 2011 Elsevier Masson SAS. All rights reserved.

  bonds has been accomplished through radical translocation and cross-coupling. Upon irradiation with visible light, copper-based photocatalyst [Cu(Xantphos)(dmp)]BF4 enabled cross-coupling of N-alkoxyphthalimides with amino acid esters or amino acids to provide δ-C(sp3)–H alkylated alcohols (31 examples, up to 92% yield) with additive BNDHP or α-C(sp3)–H alkylated alcohols (18 examples, up to 86% yield)

  C（sp 3）–H键的位点可调功能已通过自由基易位和交叉偶联完成。在可见光照射下，铜基光催化剂[Cu（Xantphos）（dmp）] BF 4使N-烷氧基邻苯二甲酰亚胺与氨基酸酯或氨基酸交叉偶联，从而提供δ-C（sp 3）-H烷基化醇（ 31个实例，添加BNDHP或α-C（sp 3）–H烷基化醇类添加剂（高达92％产率）（18个实例，高达86％产率），具有添加剂DABCO，具有高度区域选择性。

  A series of novel IMB-070593 derivatives containing a substituted benzyloxime moiety and displaying a remarkable improvement in lipophilicity were synthesized and evaluated for their in vitro antimycobacterial and antibacterial activity. Our results reveal that the target compounds 19a–m have considerable Gram-positive activity (MIC: <0.008–32 µg/mL), although they are generally less active than the reference drugs against the Gram-negative strains. In particular, compounds 19h, 19j, 19k and 19m show good activity (MICs: <0.008–4 µg/mL) against all of the tested Gram-positive strains, including ciprofloxacin (CPFX)- and/or levofloxacin (LVFX)-resistant MSSA, MRSA and MSSE. Moreover, compound 19l (MIC: 0.125 µg/mL) is found to be 2–4 fold more active than the parent IMB070593, CPFX and LVFX against M. tuberculosis H37Rv ATCC 27294.
