New resveratrol (RES) analogs were developed by replacing the aromatic ‘core’ of our initial naphthalene-based RES analogs with pseudo-heterocyclic (salicylaldoxime) or heterocyclic (benzofuran, quinoline, and benzothiazole) scaffolds. The resulting analogs were tested for their antiproliferative and vasorelaxing effect, two typical properties shown by RES. Some of the new compounds confirmed strong
通过用假杂环(水杨醛肟)或杂环(苯并呋喃,喹啉和苯并噻唑)支架取代我们最初的萘基RES类似物的芳族“核心”,开发了新的白藜芦醇(RES)类似物。测试了所得类似物的抗增殖和血管松弛作用,这是RES显示的两个典型特性。一些新化合物证实了很强的抗增殖活性,可与以前以最具活性的萘基类似物发现的抗坏血酸相媲美。特别地,3-(3,5-二羟基苯基)-7-羟基喹啉表现出最有效的抗增殖作用(IC 50 = 17.4μM)。在血管测定中,最高效力(pIC 50 = 4.92)和功效(E max 用2-(3,5-二羟基苯基)-6-羟基苯并噻唑获得=(88.2%)。这些化合物的构象分析表明,对MDA-MB-231癌细胞的抗增殖活性可能与活性最高的化合物的共同空间分布有关,尤其是与三个酚基的空间排列有关。此外,血管松弛性质与通过静电分子电势(ESP)测得的电子性质具有良好的相关性。
