developed starting from lead compound 1a. While compound 1a showed promising efficacy in several disease models, its binding to a H3 receptor as well as a hERG channel prevented it from further development. Therefore, a new round of optimization addressing the key liabilities was performed and led to discovery of compound 13 with an improved profile. Compound 13 showed significant efficacy in the rat antigen
从铅化合物1a开始开发了一种新型的,选择性的,有效的GPR4拮抗剂13。尽管化合物1a在几种疾病模型中显示出有希望的功效,但其与H 3受体以及hERG通道的结合阻止了其进一步发展。因此,进行了针对关键负债的新一轮优化,并导致发现了具有改进特性的化合物13。化合物13在耐受良好的30 mg / kg剂量下,在大鼠抗原诱导的关节炎以及痛觉过敏和血管生成模型中显示出显着的功效。
