protein-coupled receptors known as LPA1–6. A high throughput screen against LPA1 gave compound 7a as a hit. The subsequent optimization of 7a led to ONO-7300243 (17a) as a novel, potent LPA1 antagonist, which showed good efficacy in vivo. The oral dosing of 17a at 30 mg/kg led to reduced intraurethral pressure in rats. Notably, this compound was equal in potency to the α1 adrenoceptor antagonist tamsulosin
溶血磷脂酸(LPA)通过一系列G蛋白偶联受体LPA 1-6引起各种生理反应。针对LPA 1的高通量筛选得到了化合物7a。随后优化的7a导致了ONO-7300243(17a)作为新型有效的LPA 1拮抗剂,在体内表现出良好的疗效。口服剂量为30 mg / kg的17a导致大鼠尿道内压力降低。值得注意的是,该化合物是在效力的α等于1肾上腺素能受体拮抗剂坦索罗辛,在临床实践中用于治疗伴有前列腺增生(BPH)的排尿困难。与坦洛新相比,化合物17a在该剂量下对平均血压没有影响。这些结果表明,LPA 1拮抗剂可用于治疗BPH而不会影响血压。在此,我们报告了一系列独特的LPA 1拮抗剂的体内领先效果及其体内功效。
