New derivatives of verapamil (1) modified with nitroxides and their precursors were synthesized and screened for reactive oxygen species (ROS)-scavenging activities. The basic structure was modified by changing the nitrile group to an amide or the methyl substituent on tertiary nitrogen with nitroxides and their reduced forms (hydroxylamine and secondary amines). Among the new verapamil derivatives
合成了用氮氧化合物修饰的维拉帕米 ( 1 ) 的新衍生物及其前体,并筛选了清除活性氧 (ROS) 的活性。通过将腈基团变成酰胺或叔氮上的甲基取代基,用硝基氧及其还原形式(羟胺和仲胺)来修饰基本结构。其中新型维拉帕米衍生物化合物16B [Mohan, IK; 卡恩,M。怀塞尔,S。塞尔文迪兰,K.;斯里达尔,A.;加利福尼亚州卡恩斯;博格纳尔,B.;卡莱,T。希德,K。库普萨米,P.
