  Structure–activity relationships of 2-aryl-1H-indole inhibitors of the NorA efflux pump in Staphylococcus aureus

  摘要：

  The synthesis of 22 2-aryl-1H-indoles, including 12 new compounds, has been achieved via Pd- or Rh-mediated methodologies, or selective electrophilic substitution. All three methods were based on elaborations from simple indole precursors. SAR studies on these indoles and 2-phenyl-1H-indole in Staphylococcus aureus as NorA efflux pump inhibitors indicated 5-nitro-2-(3-methoxycarbonyl)phenyl-1H-indole was a slightly more potent inhibitor than the lead INF55. A promising new antibacterial lead compound against S. aureus (2-phenyl-1H-indol-5-yl)-methanol, was also found. (c) 2008 Elsevier Ltd. All rights reserved.

  Synthesis and biological activity of 6H-isoindolo[2,1-a]indol-6-ones, analogues of batracylin, and related compounds

  摘要：

  Closely related to batracylin, 6H-isoindolo[2,1-a]indol-6-ones including 2-nitro- 13a, 2-amino- 14, and 2-diethylaminopropionamide derivative 16 as well as D-ring substituted 13b, 13c or A-ring substituted 13d and 20 analogues, were synthesised and evaluated against L1210 leukaemia. Subsequent treatment of 13b and 13c with NN-diethylethylenediarnine at 180 degrees C, led to compounds 17a and 17b arising from an unexpected opening of the pyrrolidinone ring and amidification of the keto group. Under the same conditions, the dichloro derivative 13d led to the monoalkyl compound 20 which was the most cytotoxic of the series. (c) 2006 Elsevier SAS. All rights reserved.

  An efficient synthesis of 6H-isoindolo[2,1-a]indol-6-ones through rhodium-catalyzed NH-indole-directed C–H carbonylation of 2-arylindoles with carbon monoxide has been developed. Preliminary mechanistic studies revealed that this reaction proceeds via N–H bond cleavage and subsequent C–H bond cleavage. Reaction monitoring via ESI-MS was used to support the formation of five-membered rhodacycle species

• Synthesis of functionalised 2-aryl-5-nitro-1H-indoles and their activity as bacterial NorA efflux pump inhibitors

  日期：2006.2

  In order to develop structure-activity relationships and to provide access to antibacterial agents for dual action studies, a variety of aryl group-substituted 2-aryl-5-nitro-1H-indoles were synthesized and the activity of the compounds assessed as inhibitors of the NorA multidrug resistance pump in the bacterium Staphylococcus aureus. The NorA protein from the major facilitator superfamily of efflux pumps confers resistance to a variety of structurally dissimilar antimicrobials such as norfloxacin, ethidium bromide, berberine and acrillavin. The compound [4-benzyloxy-2-(5-nitro-1H-2-yl)-phenyl]-methanol was the most potent pump inhibitor. (c) 2005 Elsevier Ltd. All rights reserved.
