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

日期:——
A method for the N-acylation of 5-substituted indoles with carboxylic acids using DCC and DMAP is presented. High yields were obtained when an electron-withdrawing group was present at C-5, however the method was less effective with a C-5 electron-donating group.
