  Dietary and Microbial Oxazoles Induce Intestinal Inflammation by Modulating Aryl Hydrocarbon Receptor Responses

  摘要：

  Genome-wide association studies have identified risk loci associated with the development of inflammatory bowel disease, while epidemiological studies have emphasized that pathogenesis likely involves host interactions with environmental elements whose source and structure need to be defined. Here, we identify a class of compounds derived from dietary, microbial, and industrial sources that are characterized by the presence of a five-membered oxazole ring and induce CD1d-dependent intestinal inflammation. We observe that minimal oxazole structures modulate natural killer T cell-dependent inflammation by regulating lipid antigen presentation by CD1d on intestinal epithelial cells (IECs). CD1d-restricted production of interleukin 10 by IECs is limited through activity of the aryl hydrocarbon receptor (AhR) pathway in response to oxazole induction of tryptophan metabolites. As such, the depletion of the AhR in the intestinal epithelium abrogates oxazole-induced inflammation. In summary, we identify environmentally derived oxazoles as triggers of CD1d-dependent intestinal inflammatory responses that occur via activation of the AhR in the intestinal epithelium.

  The synthesis and SAR of novel nanomolar thrombin inhibitors with the common backbone HOOC-CH2-D-cyclohexylalanyl-3,.4-dehydroprolyl-NH-CH2-aryl-C(=NH)NH2 are described together with their ecarin clotting time (ECT) prolongation as measure for thrombin inhibition ex vivo. The aryl P1-moiety mimicking the arginine part of the D-Phe-Pro-Arg derived thrombin inhibitors turned out to be a key component for in vitro potency and in vivo activity. Optimization of this part led to compounds with improved antithrombin activity in rats and dogs after oral administration compared to the recently launched anticoagulant melagatran.
