anticancer and antioxidant agents. They are present in a variety of foods—including fruits, vegetables, tea, wine, as well as other dietary supplements—and are responsible for various health benefits. Different quercetin and resveratrol esters of Leu/Met-enkephalin and tetrapeptide Leu-Ser-Lys-Leu (LSKL) were synthesized as model systems for monitoring the influence of the peptides on biological activity
槲皮素和白藜芦醇是多酚类化合物,分别是类黄酮和二苯乙烯家族的成员,两者在饮食上均具有重要的饮食抗癌和抗氧化剂作用。它们存在于多种食物中,包括水果,蔬菜,茶,酒以及其他膳食补充剂,对多种健康有益。合成了Leu / Met-脑啡肽和四肽Leu-Ser-Lys-Leu(LSKL)的不同槲皮素和白藜芦醇酯,作为监测该肽对白藜芦醇和槲皮素生物学活性影响的模型系统。主肽基-槲皮素衍生物的通式为2 - [3 - (AA)ñ - 4 -羟基苯基] - 3,5,7--三-羟基- 4 H- 1 -苯并吡喃- 4 -上,和一般的主要肽基-白藜芦醇衍生物是式(E) - 5 - [4 - (AA)Ñ)苯乙烯基]苯- 1,3 -二醇。研究了所制备化合物的抗氧化和抗癌活性。对于基于LSKL的槲皮素和白藜芦醇衍生物均获得了显着的抗癌活性。所有制备的化合物均表现出抗氧化活性,特别是含有甲氧脑啡肽的槲皮素衍生物。
