  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.

  小分子免疫刺激剂。7,8-二取代鸟苷和结构相关化合物的合成及活性。

  摘要：

  设计并制备了一系列的7,8-二取代鸟苷衍生物，作为体液免疫反应的潜在B细胞选择性激活剂。评估了这些化合物充当B细胞有丝分裂原和增强B细胞对绵羊红细胞（SRBC）攻击（佐剂）的抗体反应的能力。此外，在鼠体外细胞试验中测试了它们刺激自然杀伤（NK）细胞反应的能力。当静脉内，皮下或口服给药时，某些化合物表现出体内活性。发现在7-烷基-8-氧代鸟苷的7-位上具有中等长度的烷基链（2-4个碳，5-7）的类似物特别有效。在该7位上带有羟烷基，氨基烷基或取代的氨基烷基取代基的化合物是弱活性的。然而，苄基，包括被杂原子取代的那些（例如，对硝基苄基，14）是有活性的。鸟苷环的C-8上的氧，硫代和硒代基团均具有很强的活性，而其他较大的取代基则没有（例如N = CN）。在该系列中，核糖环上2'-羟基的立体化学转化，使阿拉伯糖类似物70的活性降低。然而，通过（64）或没有（73）的3'羟基的去除2'-羟基导致了优
