  Immunosuppressive but Non-LasR-Inducing Analogues of the Pseudomonas aeruginosa Quorum-Sensing Molecule N-(3-Oxododecanoyl)-l-homoserine Lactone

  摘要：

  The Pseudomonas aeruginosa quorum-sensing molecule N-(3-oxododecanoyl)-l-homoserine lactone (1) is involved not only in bacterial activation but also in subversion of the host immune system, and this compound might thus be used as a template to design immunosuppressive agents, provided derivatives devoid of quorum-sensing activity could be discovered. By use of a leukocyte proliferation assay and a newly developed bioluminescent P. aeruginosa reporter assay, systematic modification of 1 allowed us to delineate the bacterial LasR-induction and host immunosuppressive activities. The main determinant is replacement of the methylene group proximal to the beta-ketoamide in the acyl chain of 1 with functions containing heteroatoms, especially an NH group. This modification can be combined with replacement of the homoserine lactone system in 1 with stable cyclic groups. For example, we found the simple compound N(1)-(5-chloro-2-hydroxyphenyl)-N(3)-octylmalonamide (25d) to be over twice as potent as 1 as an immune suppressor while displaying LasR-induction antagonist activity.
