Abstract

Inflammation is a hallmark of microbial infection in mammals and is the result of a pathogen-induced release of inflammatory effectors. In humans a variety of germ-line encoded receptors, so-called pattern-recognition receptors, respond to conserved signatures on invading pathogens, which results in the transcriptional activation of pro-inflammatory responses. Inflammation is often detrimental to the host and leads to tissue damage and/or systemic dysfunctions. Thus, specific inhibitors of these pathways are desirable for medical interventions. Herein we report on the synthesis and use of some chromium-containing compounds (arene-Cr(CO)(3) complexes) with a core structure related to anti-inflammatory diterpenes produced by the sea whip Pseudopterogorgia elisabethae. By using cell-based reporter assays we identified complexes with a potent inhibitory activity on tumour necrosis factor (TNF), Toll-like receptor (TLR), and nucleotide binding domain, leucine-rich repeat-containing receptor (NLR) pathways. Moreover, we found one complex to be a specific inhibitor of inflammatory responses mediated by the NLR protein NOD2, a pivotal innate immune receptor involved in bacterial recognition. Synthesis and characterisation of a set of derivatives of this substance revealed structural requirements for NOD2 specificity. Taken together, our studies suggest this type of arene-Cr(CO)(3) complex as a potential lead for the development of antiphlogistica and pharmacologically relevant NOD2 inhibitors.
