  Meridianin D Analogues Display Antibiofilm Activity against MRSA and Increase Colistin Efficacy in Gram-Negative Bacteria

  摘要：

  In the last 30 years, development of new classes of antibiotics has slowed, increasing the necessity for new options to treat multidrug resistant bacterial infections. Development of antibiotic adjuvants that increase the effectiveness of currently available antibiotics is a promising alternative approach to classical antibiotic development. Reports of the ability of the natural product meridianin D to modulate bacterial behavior have been rare. Herein, we describe the ability of meridianin D to inhibit biofilm formation of methicillin-resistant Staphylococcus aureus (MRSA) and to increase the potency of colistin against colistin-resistant and sensitive Gram-negative bacteria. Analogues were identified that are capable of inhibiting and dispersing MRSA biofilms and lowering the colistin MIC to below the CLSI breakpoint against Acinetobacter baumannii, Klebsiella pneumoniae, and Escherichia coli.

  Novel N-H and N-alkylated derivatives of meridianins have been synthesized as potential antitumor agents by a two-step conversion of N-tosyl-3-acetylindoles or N-alkyl-3-acetylindoles to the corresponding enaminones using DMF-DMA, with or without added pyrrolidine. Further cyclization with guanidine gave the corresponding 2-aminopyrimidines. The structures of the compounds, thus obtained, were proved

  通过使用DMF-DMA将N-甲苯磺酰基-3-乙酰基吲哚或N-烷基-3-乙酰基吲哚经两步转化为相应的烯胺酮，合成了经络胺的新型N- H和N-烷基化衍生物作为潜在的抗肿瘤药。或不添加吡咯烷。用胍进一步环化得到相应的2-氨基嘧啶。由此获得的化合物的结构通过1 H和13 C NMR光谱，NOE实验和X射线分析证明。

  A set of NF-kappa B-inducing kinase (NIK) inhibitors was used to develop a molecular docking-based QSAR model by using nonlinear regression method. The accuracy of the QSAR model was remarkably improved by integrating the docking scores and key interaction profiles. Two indole-aminopyrimidine derivatives 32a and 32b predicted as NIK inhibitors were synthesized and biologically evaluated. The significant correlationship between experimental data and MD-SVR model-predicted results were observed. The binding mode of 32a and 32b with NIK were further investigated by dynamic simulations. Compound 32b was proposed as a promising lead for the findings of highly potent inhibitors.

  The marine natural products meridianins A and C-E have been synthesized for the first time starting from the appropriate N-tosyl-3-acetylindole. A facile two-step conversion of N-tosyl-3-acetylindoles to the corresponding meridianins by treatment with dimethylformamide dimethylacetal and further cyclization of the resulting enaminone with aminoguanidine is described. This method has also been applied for the preparation of the 3-[(2-amino)pyrimidin-4-yl]-7-azaindole. (C) 2001 Elsevier Science Ltd. All rights reserved.
