In this paper, we describe a new class of products in which NO-donor moieties are linked to either the 3-OH (4a-f) or 2-OH group (7a-c) of ascorbic acid (ASA). Log Ps and pK(a)s of these products were experimentally evaluated. All the compounds were tested for their antioxidant activity on lipidic peroxidation induced by Fe(3+)-ADP/NADPH in lipids of microsomal membranes of rat hepatocytes. Only 3-O
在本文中,我们描述了一类新的产品,其中NO供体部分与
抗坏血酸(A
SA)的3-OH(4a-f)或2-OH基团(7a-c)连接。实验评估了这些产物的Log Ps和pK(a)。测试了所有化合物对大鼠肝细胞微粒体膜脂质中Fe(3 +)-
ADP /
NADPH诱导的脂质过氧化的抗氧化活性。仅3-O系列显示
抗氧化剂活性,并且似乎主要取决于亲脂性。这两个系列均触发了体外NO依赖的血管扩张药特性。
