Extensive SAR studies in our benzylpyrazole series of CCR5 antagonists have shown that both lipophilic and hydrophilic substituents on the phenyl of the benzyl group increase antiviral potency. However, improvements in pharmacokinetic profiles were generally only observed with more lipophilic substitutions. 4-Biphenyl (51) performed the best in this regard. Highly lipophilic substituents impart undesirable
在我们的苄基吡唑系列CCR5拮抗剂中,广泛的SAR研究表明,苄基苯基上的亲脂性和亲水性取代基均可提高抗病毒效力。然而,通常仅通过更多的亲脂取代观察到药代动力学特征的改善。在这方面,4-联苯(51)表现最好。高度亲脂性取代基赋予这些CCR5拮抗剂不良的离子通道活性。烷氧基取代基提供了抗病毒活性,药代动力学参数和选择性之间的良好平衡。与母体化合物9相比,包含3,4-二甲氧基取代基的化合物42b和42d被认为是最有希望的改进。它们显示出改进的抗病毒活性,同时保留了良好的药代动力学特性和选择性。
