In an effort to develop ATP-competitive VEGFR-2 selective inhibitors, a series of new quinoxaline-based derivatives was designed and synthesized. The target compounds were biologically evaluated for their inhibitory activity against VEGFR-2. The design of the target compounds was accomplished after a profound study of the structure activity relationship (SAR) of type-II VEGFR-2 inhibitors. Among the
为了开发具有ATP竞争性的VEGFR-2选择性抑制剂,设计并合成了一系列新的基于喹喔啉的衍生物。从生物学上评估目标化合物对VEGFR-2的抑制活性。在深入研究II型VEGFR-2抑制剂的结构活性关系(SAR)之后,完成了目标化合物的设计。在合成的化合物中,1-(2-(((4-甲氧基苯基)氨基)-3-氧代-3,4-二氢喹喔啉-6-基)-3-苯基脲(VIIa)对VEGFR-2的抑制活性最高。进行了涉及分子对接和场比对的分子建模研究,以解释新合成化合物的可变抑制活性。
