A series of oxazolopyrimidine‐based ureas and amides were designed, synthesized, and biologically evaluated for their antiproliferative and antiangiogenic activities. These compounds were identified to exhibit inhibitory activities against human umbilical vein endothelial cells (HUVEC) in vitro. Among these compounds, compound 22 effectively inhibited the migration and capillary‐like tube formation
设计、合成了一系列基于恶唑并嘧啶的脲和酰胺,并对其抗增殖和抗血管生成活性进行了生物学评估。经鉴定,这些化合物在体外对人脐静脉内皮细胞 (HUVEC) 具有抑制活性。在这些化合物中,化合物22有效地抑制了人脐静脉内皮细胞的迁移和毛细血管样管的形成。它还表现出对大鼠主动脉环毛细血管萌发的浓度依赖性抑制。初步机制研究表明,化合物 22 通过降低 PI3K 和 ERK 1/2 磷酸化来抑制蛋白激酶的激活。这些结果支持进一步研究这类化合物作为潜在的抗癌剂。
