  Design, synthesis and antibacterial activity of novel andrographolide derivatives

  摘要：

  A series of andrographolide derivatives were synthesized through a facile condensation reaction with different carboxylic acids. The new compounds were characterized and screened for their antibacterial activities. A number of the new compounds significantly reduced bacterial quorum sensing virulence factors production in Pseudomonas aeruginosa, essential for pathogenesis. Compound 11b showed the best activity among all the new compounds. (C) 2010 Elsevier Ltd. All rights reserved.
