overactive bladder and painful bladder syndrome; however, there is a potential risk of low blood pressure. We report herein the synthesis and structure–activity relationships of novel phenylglycine derivatives that led to the identification of KPR-2579 (20l), a TRPM8 selective antagonist. KPR-2579 reduced the number of icilin-induced wet-dog shakes and rhythmic bladder contraction in rats, with no negative
瞬态受体电位褪黑素8(TRPM8)被无害的感冒和化学物质激活,该通道的拮抗剂被认为对疼痛和泌尿系统疾病有效。有人提出,TRPM8拮抗剂N-(3-氨基丙基)-2-[((3-甲基苯基)甲基]氧基} -N-(2-噻吩甲基)苯甲酰胺盐酸盐(AMTB)可有效治疗膀胱过度活动症和膀胱疼痛综合症 但是,存在潜在的低血压风险。我们在此报告了新型苯甘氨酸衍生物的合成与结构-活性的关系,从而鉴定了TRPM8选择性拮抗剂KPR-2579(20l)。KPR-2579 减少了依西林诱导的湿狗摇动和节律性膀胱收缩的次数,在有效剂量下对心血管没有负面影响。
