• Expedient synthesis of unsaturated amide alkaloids from <i>Piper</i> spp: Exploring the scope of recent methodology
  作者：George M. Strunz、Heather J. Finlay

  DOI：10.1139/v96-046

  日期：1996.3.1

  The Sakai aryl aldehyde – cyclic ketone aldol – Grob fragmentation sequence was extended to cinnamaldehyde and cyclohexanone, and the product was elaborated to analogues of the alkaloid piperstachine. The effects of substituents on the reaction involving cinnamaldehyde were studied. The aldol-fragmentation sequence failed with benzaldehyde when cyclooctanone or cyclobutanone was substituted for cyclohexanone or cyclopentanone, and the reasons for this failure were examined. Four-carbon Wittig homologation of the piperonal–cyclobutanone aldol-fragmentation product, a hypothetical route to alkaloids such as retrofractamide A, was thus not viable. Instead, three-carbon homologation of the readily available piperonal–cyclopentanone product, using alkyne chemistry recently disclosed by Lu and Trost, afforded these alkaloids in excellent overall yield. The alkyne isomerization was also used to effect efficient syntheses of pellitorine and several other non-aromatic 2E,4E-dienoic Piper amide alkaloids. Key words: Piper, amides, alkaloids, insecticides, aldol, fragmentation, cinnamaldehydes, alkyne, redox, isomerization.

  Sakai芳基醛-环酮Aldol-Grob断裂序列被扩展到肉桂醛和环己酮，并将产物改造为吡啶碱类似物。研究了涉及肉桂醛的反应中取代基的影响。当环辛酮或环丁酮替代环己酮或环戊酮时，苯甲醛无法进行Aldol-断裂序列，对此失败的原因进行了研究。对吡哆醛-环丁酮Aldol-断裂产物进行了四碳Wittig同系化，这是通往碱类如retrofractamide A的假设路线，但该方法并不可行。相反，利用Lu和Trost最近披露的炔化学，对易得的吡哆醛-环戊酮产物进行了三碳同系化，以极高的总产率制备了这些碱类。炔异构化还被用于高效合成辣椒碱和几种其他非芳香2E,4E-二烯酸Piper酰胺类碱类。关键词：Piper、酰胺、碱类、杀虫剂、Aldol、断裂、肉桂醛、炔、氧化还原、异构化。

• Antibacterial activity of 2-alkynoic fatty acids against multidrug-resistant bacteria

  The first study aimed at determining the structural characteristics needed to prepare antibacterial 2-alkynoic fatty acids (2-AFAs) was accomplished by synthesizing several 2-AFAs and other analogs in 18-76% overall yields. Among all the compounds tested, the 2-hexadecynoic acid (2-HDA) displayed the best overall antibacterial activity against Gram-positive Staphylococcus aureus (MIC = 15.6 mu g/mL), Staphylococcus saprophyticus (MIC = 15.5 mu g/mL), and Bacillus cereus (MIC = 31.3 mu g/mL), as well as against the Gram-negative Klebsiella pneumoniae (7.8 mu g/mL) and Pseudomonas aeruginosa (MIC = 125 mu g/mL). In addition, 2-HDA displayed significant antibacterial activity against methicillin-resistant S. aureus (MRSA) ATCC 43300 (MIC = 15.6 mu g/mL) and clinical isolates of MRSA (MIC = 3.9 mu g/mL). No direct relationship was found between the antibacterial activity of 2-AFAs and their critical micelle concentration (CMC) suggesting that the antibacterial properties of these fatty acids are not mediated by micelle formation. It was demonstrated that the presence of a triple bond at C-2 and the carboxylic acid moiety in 2-AFAs are important for their antibacterial activity. 2-HDA has the potential to be further evaluated for use in antibacterial formulations.

• Synthesis and biological activity of alkynoic acids derivatives against mycobacteria

  2-Alkynoic acids have bactericidal activity against Mycobacterium smegmatis but their activity fall sharply as the length of the carbon chain increased. In this study, derivatives of 2-alkynoic acids were synthesized and tested against fast- and slow-growing mycobacteria. Their activity was first evaluated in M. smegmatis against their parental 2-alkynoic acids, as well as isoniazid, a first-line antituberculosis drug. The introduction of additional unsaturation or heteroatoms into the carbon chain enhanced the antimycobacterial activity of longer chain alkynoic acids (more than 19 carbons long). In contrast, although the modification of the carboxylic group did not improve the antimycobacterial activity, it significantly reduced the toxicity of the compounds against eukaryotic cells. Importantly, 4-(alkylthio) but-2-ynoic acids, had better bactericidal activity than the parental 2-alkynoic acids and on a par with isoniazid against the slow-grower Mycobacterium bovis BCG. These compounds had also low toxicity against eukaryotic cells, suggesting that they could be potential therapeutic agents against other types of topical mycobacterial infections causing skin diseases including Mycobacterium abscessus, Mycobacterium ulcerans, and Mycobacterium leprae. Moreover, they provide a possible scaffold for future drug development. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
