  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.

  The Chan–Lam reaction remains a highly utilized transformation for C–N bond formation. However, anilines remain problematic substrates due to their lower nucleophilicity. To address this problem, we developed an electrochemically mediated Chan–Lam coupling of aryl boronic acids and amines utilizing a dual copper anode/cathode system. The mild conditions identified have enabled the preparation of a

  Chan-Lam反应仍然是C-N键形成的一种高度利用的转化方法。但是，由于苯胺的亲核性较低，因此它们仍然是有问题的底物。为了解决这个问题，我们利用双铜阳极/阴极系统开发了一种化学介导的芳基硼酸和胺的Chan-Lam偶联。所确定的温和条件使得能够以良好的产率和化学选择性制备多种官能化的联芳基苯胺。

  Pd-PEPPSI（钯-吡啶增强的预催化剂制备过程的稳定和引发）配合物现已成为定义为C–C和C–N键形成的催化剂。与此相关，我们准备了一个由六个空气和水分稳定的，简单到大体积的苄基取代基组成的系列，这些取代基带有苯并咪唑核心Pd-PEPPSI复合物C1-C6。通过X射线衍射（XRD）研究证实了C6的结构，并通过％V Bur确定了N杂环卡宾的空间压力计算。值得注意的是，这些NHC-Pd-Py骨架表现出苯并咪唑NHCs良好的σ供体和π扩展电子性质，这是催化的基本要求。与先前报道的其他催化剂在温和的反应条件下，在3-氯吡啶和各种芳基/杂芳基胺之间进行布赫瓦尔德-哈特维格交叉偶联反应相比，已证明所制备的配合物具有出色的压倒性。另一方面，不需要外部添加剂或配体将铅母体分子完全转化为产物。更值得注意的是，与其他配合物C1-C5相比，C6具有明显的催化活性用于C–N键的形成。此外，底物的范围可以扩展到其

  effective process to curb the progressive and fatal neurological Alzheimer's disease (AD). Herein, we explored the potential inhibitory activities of various pyridine, quinoxaline, and triazine derivatives (3a-k, 6a-j and 11a-h) against AChE and BuChE enzymes by following the modified Ellman's method. Further, anti-oxidant property of these libraries was monitored using DPPH (2,2′-diphenyl-1-picryl-hydrazylhydrate)

  Examination of the scope and limitation of the Buchwald-Hartwig cross-coupling reaction in micellar medium is reported. An array of aryl or heteroaryl halides were coupled to diverse nitrogen coupling partners using a combination of [(allyl)PdCl](2) and cBRIDP to afford the corresponding products in moderate to excellent yields. 30 examples are reported, including polar solid and fairly water-soluble organic substrates/reagents.

  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.
