physicochemical properties of a click-based lead compound would be affected by the replacement of its triazole ring with a pyrazole or an imidazole ring. Compound A1, a click-based lead from our previous work, was a selective and moderate inhibitor against VEGFR2. Eight new derivatives of A1 were synthesized, from which a pyrazole derivative B2 was selected as a new lead. B2 maintained the in vitro activity
这项工作主要证明了以点击为基础的先导化合物的物理化学性质如何受到吡唑或咪唑环取代其三唑环的影响。化合物A1是我们以前的工作中基于点击的前导药物,是一种选择性且中度的VEGFR2抑制剂。合成了八个新的A1衍生物,从中选择了吡唑衍生物B2作为新的前导物。B2维持A1的体外活性。B2在pH 2.0和pH 7.4下的溶解度分别提高到1310和1.7μg/ mL。其log D值为3.4将有利于B2 在未来的工作中用亲水性片段进行修饰,以进一步提高肠道的溶解性。
