  δ-Carbolines and their ring-opened analogs: Synthesis and evaluation against fungal and bacterial opportunistic pathogens

  摘要：

  Previous studies have indicated that the delta-carboline (2) ring system derived from the natural product cryptolepine (1) may represent a pharmacophore for anti-infective activity. This paper describes the design and synthesis of a small library of substituted delta-carbolines and the evaluation of the anti-fungal and anti-bacterial activities. An evaluation of the anti-bacterial activity of a previously reported library of ring-opened analogs was also conducted to provide an opportunity to test the hypothesis that both group of compounds may have the same biological target. Results indicate that against a selected group of fungal pathogens, substituted delta-carbolinium analogs displayed higher potency and several fold lower cytotoxicity than cryptolepine the parent natural product. Both the delta-carbolinium compounds and their ring-opened analogs, exhibited equally high anti-bacterial activity against the selected pathogens and especially against the gram positive bacteria evaluated.

  健壮的对乙酰氨基咪唑亚丙基四环四环化合物：高效的N-杂芳基氯化物胺化催化剂

  摘要：

  已经成功开发了一系列健壮的N杂环卡宾Palladacycles。这些显示出高催化活性和对具有挑战性的N-杂芳基氯化物的选择性。不同的伯胺和仲胺与该催化体系完全相容。值得注意的是，在我们的催化转化中使用伯胺时，没有检测到双胺化产物。此外，该协议已成功扩展到合成罗格列酮，一种用于糖尿病的临床药物，突出了其潜在的药物可行性。

  well-defined palladium complexes were found to be excellent precatalysts for Buchwald–Hartwig amination of aryl chlorides with amines in air. The electronic effect of the Pd-PEPPSI complexes and the effect of ancillary pyridine ligands were evaluated, among which complex C3 exhibited the most efficiency. It was demonstrated that the cross-coupling products were obtained in excellent yields in the presence

  precatalyst Pd-PEPPSI-IPr(NMe2)2, in which the IPr ligand was modified by attachment of two dimethylamino groups on to the 4- and 5-positions of the imidazolyl heterocycle, was found to show high catalytic efficiency in the Buchwald-Hartwig amination under mild conditions using Cs2CO3 as a weak base, using a low catalyst loading of 1 mol-%.

  Previous studies on the indoloquinoline alkaloid, cryptolepine (2), revealed that it has antii-nfective properties among other activities. Using Structure-activity relationship (SAR) techniques, several ring-opened analogs of cryptolepine (3-phenylaminopyridinium and 3-phenylaminoquinolinium derivatives) were designed to improve the potency and lower the cytotoxicity shown by several of the precursor agents. Results indicate that these ring-opened analogs constitute new anti-infective agents with over a 100-fold potency and several fold lower cytotoxicity than cryptolepine from which they are derived.

  We report herein a well-defined NHC-Pd(II)-Im(NHC=N-heterocyclic carbene; Im=1-methylimidazole) complex catalyzed C-N coupling of primary amines with aryl chlorides. Under the optimal reaction conditions, a variety of primary amines can be coupled with aryl chlorides to give the amination products in good to high yields within 4 h. It is worthy of noting here that the NHC-Pd(II)-Im complex showed especially high catalytic activity toward challenging sterically hindered substrates including both of aryl amines and aryl chlorides. In addition, alkyl amines were also proved to be suitable reaction partners to give the corresponding amination products in good to high yields. (C) 2012 Elsevier Ltd. All rights reserved.
