The design and synthesis of a series of substituted 6-amino-4-(2,4-dimethoxyphenyl)-[1,2]dithiolo[4,3-b]pyrrol-5-ones are described. All the synthesized compounds were evaluated for raising leukocyte count activities in normal mice. Four compounds (8a, b, d, h) exhibited raising leukocyte count activities close or higher than positive control recombinant human granulocyte colony stimulating factor (rhG-CSF), and some (8e–g, k, p, r) had a moderate effect. Among them, the most potent compound 8a was evaluated for its antileukopenia activity in cyclophosphamide (CTX) treated mice. Interestingly, 8a exhibited significant antileukopenia activity as compared to rhG-CSF. The results suggest that this kind of compounds might be utilized for the development of new candidate for treatment of leukocytopenia.
本文描述了一系列取代的6-amino-4-(2,4-二甲氧基苯)-[1,2]二硫代[4,3-b]吡咯-5-酮的设计与合成。所有合成的化合物均进行了评估,观察其在正常小鼠中提升白细胞计数的活性。四种化合物(8a、b、d、h)表现出接近或高于阳性对照重组人粒细胞集落刺激因子(rhG-CSF)的提升白细胞计数活性,而一些化合物(8e–g、k、p、r)则表现出中等的效果。其中,最有效的化合物8a在环磷酰胺(CTX)处理的小鼠中进行了抗白细胞减少活性的评估。有趣的是,与rhG-CSF相比,8a表现出了显著的抗白细胞减少活性。结果提示,这类化合物可能用于开发新的白细胞减少症治疗候选药物。
