The bradykinin B1 receptor is induced following tissue injury and/or inflammation. Antagonists of this receptor have been studied as promising candidates for treatment of chronic pain. We have identified aryl sulfonamides containing a chiral chroman diamine moiety that are potent antagonists of the human B1 receptor. Our previously communicated lead, compound 2, served as a proof-of-concept molecule
缓激肽B1受体在组织损伤和/或炎症后被诱导。已经研究了这种受体的拮抗剂作为治疗慢性疼痛的有希望的候选者。我们已经鉴定出含有手性苯并二氢吡喃二胺部分的芳基磺酰胺,它们是人B1受体的有效拮抗剂。我们先前交流过的铅化合物2充当了概念验证分子,但具有不良的药代动力学特性。在代谢谱分析的指导下,我们进行了结构-活性关系研究,并确定了2的有效类似物。磺酰胺部分的变化表明,偏爱3-和3,4-二取代的芳基磺酰胺,而较大的仲胺和叔胺则优选B1受体效力的苄胺位置。修饰分子的β-氨基酸核心导致发现具有改善的体外药代动力学性质的高效化合物。在人类受体上最有效的类似物化合物38在兔B1受体细胞测定中也具有活性。此外,化合物38在两个兔子模型,具有血压读数的药效模型和炎性疼痛功效模型中表现出体内活性。
