modifications such as varying the amine group, the distance separating the amine substituent from the phenothiazine nucleus, and the linking group had little effect. Compound 6 was more effective than probucol, a known antioxidant, in blocking Cu2+ catalyzed oxidation of low-density lipoprotein (LDL) as measured by competitive scavenger receptor mediated degradation of 125I-labeled acetyl-LDL by mouse peritoneal
合成了一系列吩噻嗪,并将其作为铁依赖性脂质过氧化的体外抑制剂进行评估。2-(10H-吩噻嗪-2-基氧基)-N,N-二甲基乙醇胺甲磺酸盐(6)的MIC(给出大于或等于50%抑制作用的最低测试浓度)为0.26 microM。尽管在N-10处的甲基取代使活性降低了近100倍,但其他结构修饰(例如改变胺基,将胺取代基与吩噻嗪核之间的距离以及连接基团)影响很小。通过竞争性清道夫受体介导的小鼠腹膜巨噬细胞体外降解125I标记的乙酰基LDL,化合物6在抑制低密度脂蛋白(LDL)的Cu2 +催化的氧化中比普罗布考更有效。
