  8-Substituted guanosine and 2'-deoxyguanosine derivatives as potential inducers of the differentiation of Friend erythroleukemia cells

  摘要：

  A variety of 8-substituted guanosine and 2'-deoxyguanosine derivatives were synthesized and tested as inducers of the differentiation of Friend murine erythroleukemia cells in culture. The most active agents in the guanosine series were 8-substituted-N(CH3)2, -NHCH3, -NH2, -OH, and -SO2CH3, which caused 68, 42, 34, 33, and 30% of erythroleukemia cells to attain benzidine positivity, a functional measure of maturation, at concentrations of 5, 1, 0.4, 5, and 5 mM, respectively. The 8-OH derivative of the 2'-deoxyguanosine series produced comparable activity, causing 62% benzidine-positive cells at a level of 0.2 mM. These findings indicate that 8-substituted analogues of guanosine and 2'-deoxyguanosine have the potential to terminate leukemia cell proliferation through conversion to end-stage differentiated cells.

  The invention relates to a method for labeling and fragmenting a single- or double-stranded deoxyribonucleic acid (DNA) comprising the following steps: chemically fragmenting the DNA by creating at least one abasic site on said DNA, attaching a marker to at least one of the fragments by means of a labeling reagent, said reagent covalently and predominantly coupling to at least one phosphate of said fragment. The invention finds a preferred application in the field of diagnosis.

  该发明涉及一种用于标记和分解单链或双链脱氧核糖核酸（DNA）的方法，包括以下步骤：通过在DNA上创建至少一个缺碱位点来化学分解DNA，通过标记试剂将标记物附着到至少一个片段上，该试剂以共价键和主要地耦合到至少一个片段的磷酸基。该发明在诊断领域中找到了一个首选的应用。
