  Fine Tuning of physico-chemical parameters to optimise a new series of novobiocin analogues

  摘要：

  A novel series of novobiocin analogues has been synthesised by removing the lipophilic aryl chain in novobiocin and introducing an amino substituent. The structural modifications have been dictated by the control of lipophilicity and the dissociation constant of the resulting compounds. Antibacterial activity of the new coumarin derivatives could be correlated with the amount of uncharged form in physiological conditions. (C) 2001 Elsevier Science Ltd. All rights reserved.
