The macrophage infectivity potentiator (MIP) protein is a major virulence factor of Legionella pneumophila, the causative agent of Legionnaires’ disease. MIP belongs to the FK506-binding proteins (FKBP) and is necessary for optimal intracellular survival and lung tissue dissemination of L. pneumophila. We aimed to identify new small-molecule inhibitors of MIP by starting from known FKBP12 ligands. Computational analysis, synthesis, and biological testing of pipecolic acid derivatives revealed a promising scaffold for new MIP inhibitors.
