Anti-inflammatory effect of novel analogs of natural enkephalinase inhibitors in a mouse model of experimental colitis.

Abstract:

AIM:The pharmacotherapy of inflammatory bowel disease is difficult and currently available treatments bring mostly poor and unsatisfactory results. RESULTS:The purpose of this work was the synthesis of opiorphin, sialorphin, spinorphin and a series of their analogs and the in vitro characterization of their effect on degradation of enkephalin by neutral endopeptidase and aminopeptidase N. Consequently, we investigated in vivo the anti-inflammatory effect of the most active inhibitors selected in the in vitro studies (Pal-KKQRFSR & Pal-KKQHNPR). Putative inhibitor - enzyme (neutral endopeptidase or aminopeptidase N) complexes are also presented and their binding interfaces are identified. CONCLUSION:Our results suggest that Pal-KKQHNPR has the potential to become a valuable template for anti-inflammatory therapeutics for the treatment of GI tract inflammation.

  • Structure-activity relationships of furanones, dihydropyrrolones and thiophenones as potential quorum sensing inhibitors.

    abstract::Since their initial isolation from the marine alga Delisea pulchra, bromofuranones have been investigated as potential inhibitors of quorum sensing (QS) in various bacterial strains. QS is an important mechanism by which bacteria co-ordinate their molecular response to the environment. QS is intrinsically linked to ba...
