migration and invasion were evaluated using the chick chorioallantoic membrane (CAM) assay, MTT, wound-healing, and Cultrex® BME cell invasion assay models, respectively. Analogues with high docking scores showed promising anti-angiogenic activity in the CAM assay. In general, ester analogues (5, 6, and 8–10) proved to be of higher anti-migratory activity whereas ether analogues (11–14) showed better anti-proliferative
源自二溴酪氨酸的生物活性次生代谢物在海洋海绵(例如Aplysina物种的海绵)中很常见。Verongiaquinol(1),3,5-二溴-1-羟基-4-氧代环己-2,5-二烯-1-乙酰胺和aeroplysinin-1是此类生物活性代谢物的实例。先前的研究已经显示了Verongiaquinol的强效抗微生物和细胞毒性特性以及aeroplysinin-1的抗血管生成活性。本文介绍的工作显示了具有抗血管生成,抗增殖和抗迁移特性且细胞毒性可忽略不计的二溴酪氨酸启发的酚酯和醚类似物的设计和合成。根据对接实验,在VEGFR2的ATP结合位点上合成了几种类似物,并使用鸡绒膜尿囊膜(CAM)测定法,MTT,伤口愈合法评估了它们的抗血管生成潜力以及抑制血管生成和前列腺癌增殖,迁移和侵袭的能力。康复,和Cultrex®BME细胞侵袭测定模型。具有高对接得分的类似物在CAM测定中显示出有希望的抗血管生成活性。通
