  Structure–activity relationships of the peptide deformylase inhibitor BB-3497: modification of the methylene spacer and the P1′ side chain

  摘要：

  Structural modifications to the peptide deformylase inhibitor BB-3497 are described. In this paper, we describe the initial SAR around this lead for modifications to the methylene spacer and the P1' side chain. Enzyme inhibition and antibacterial activity data revealed that the optimum distance between the N-formyl hydroxylamine metal binding group and the P1' side chain is one unsubstituted methylene unit. Additionally, lipophilic P1' side chains that closely mimic the methionine residue in the substrate provided compounds with the best microbiological profile. (C) 2003 Elsevier Ltd.

  Water/n-octanol partition coefficients (log P) for 33 1,2-dithiole-3-thiones and for 18 1,2-dithiol-3-ones were determined by RP-HPLC measurement of the concentration of the solute in aqueous solution after equilibrium. Depending on the nature of the substituents (alkyl or aryl) and their position(s) (4,5, or both) on the dithiole nucleus, some peculiar behaviors were revealed. Therefore, different
