Determination Of 2-Chloro-2′-deoxyadenosine (Antileukemic Agent) and Related Compounds by Electrochemical Method
摘要:
Electrochemical method for determination of 2-chloro-2'-deoxyadenosine and related compounds modified in exocyclic 6-NH2 group is described. Electrochemical detection of investigated compounds, based on the electrooxidation process of the adenine moiety, has been performed in aqueous solutions, in the pH range 2-9, on a glassy carbon electrode.
合成了含有仲6-NH 2基团(5a-c)或8-Br取代基(9)的2-氯-2'-脱氧腺苷(1a)的衍生物。将它们与含有吡咯并[2,3- b ]吡啶,吡咯并[3,2- c ]吡啶或吡唑并[3,4- d ]嘧啶环系统作为各种白血病细胞系抑制剂的环修饰同类物一起进行了测试。。仅8-Br衍生物9表现出抑制活性,而碱基修饰的同类物没有活性。化合物1a在ap K a = 1.4(2'-脱氧腺苷在p K a= 3.8)。质子化发生在N(7),而不是在dA观察到的N(1)。
