  7-Substituted-pyrrolo[3,2-d]pyrimidine-2,4-dione derivatives as antagonists of the transient receptor potential ankyrin 1 (TRPA1) channel: A promising approach for treating pain and inflammation

  摘要：

  The transient receptor potential ankyrin 1 (TRPA1) channel is activated by a series of by-products of oxidative/nitrative stress, produced under inflammatory conditions or in the case of tissue damage, thus generating inflammatory and neuropathic pain and neurogenic inflammatory responses. These findings have identified TRPA1 as an emerging opportunity for the design and synthesis of selective inhibitors as potential analgesic and antiinflammatory agents. Herein we present the synthesis and functional evaluation of a new series of 7-substituted-1,3-dimethyl-1,5-dihydro-pyrrolo[3,2-d]pyrimidine-2,4-dione derivatives designed as TRPA1 antagonists. A small library of compounds has been built by the introduction of differently substituted N-7-phenylacetamide or N-7-[4-(substituted-phenyl)-thiazol-2-yl]acetamide chains. All the synthesized compounds were assayed to evaluate their ability to block acrolein-mediated activation of native human and rat TRPA1 channels employing a fluorometric calcium imaging assay. Our study led us to the identification of compound 3h which showed considerably improved potency (IC50 = 400 nM) against human TRPA1 with regard to some of the most representative antagonists previously reported and integrated in our screening program as reference compounds. In addition, 3h proved to maintain its efficacy toward rTRPA1, which designates it as a possible candidate for future evaluation of in vivo efficacy in rodent animal model of inflammatory and neuropathic pain.
