  摘要：

  A scaffold-hopping strategy towards a new pyrazolo[1,5-a]pyridine based core using molecular hybridization of two structurally distinct EP1 antagonists, followed by structure-activity relationship guided optimization, resulted in the identification of potent EP1 antagonists exemplified by 4c, 4f, and 4j, which were shown to reduce pathological intravesical pressure in rats when administered at 1 mg/kg iv.

  A pyrazolopyridine derivative represented by the following formula (I) or a pharmacologically acceptable salt thereof exhibits a strong EP 1 receptor antagonistic effect. Thus, the derivative or the pharmacologically acceptable salt is useful as a therapeutic agent for lower urinary tract symptoms (LUTS), particularly, overactive bladder syndrome (OABs), or a prophylactic agent therefor and furthermore, is also useful in the treatment, prevention, or suppression of various pathological conditions in which the EP 1 receptor is involved, such as inflammatory disease, pain disease, osteoporosis, and cancer. [A is a benzene ring or the like, Y 1 is C 1-6 alkylene, R 1 is —C(═O)—OZ 1 or the like, Z 1 is H or the like, R 2 is a branched C 3-6 alkyl group or the like, R 3 is H or the like, R 4 is a hydrogen atom or the like, and R 5 is a hydrogen atom or the like].

  以下式(I)所表示的吡唑吡啶衍生物或其药学上可接受的盐，表现出强烈的EP1受体拮抗作用。因此，该衍生物或药学上可接受的盐可用作下尿路症状（LUTS），特别是过度活跃膀胱综合症（OABs）的治疗剂或预防剂，此外，它还可用于治疗、预防或抑制EP1受体参与的各种病理情况，如炎症性疾病、疼痛疾病、骨质疏松症和癌症。其中，A为苯环或类似物，Y1为C1-6烷基，R1为-C（═O）-OZ1或类似物，Z1为H或类似物，R2为支链C3-6烷基或类似物，R3为H或类似物，R4为氢原子或类似物，R5为氢原子或类似物。
