6-Substituted purine and 9-beta-d-ribofuranosyl purine analogues were synthesized and their biological activities were evaluated. CD Spectra and thermal melting studies showed that compounds 8, 9, 10 could interact with RNA and DNA in solution. Compound 8 and 10 may bind with RNA single strand and interfere the formation of RNA duplex. Among of these compounds, compound 8 showed middle inhibition on
合成了6-取代的嘌呤和9-β-d-呋喃核糖基嘌呤类似物,并评估了它们的生物学活性。CD光谱和热熔研究表明,化合物8、9、10可以与溶液中的RNA和DNA相互作用。化合物8和10可与RNA单链结合并干扰RNA双链体的形成。在这些化合物中,化合物10对HeLa细胞(70.21%)和HL-60细胞(70.85%)的生长在10 microM时显示中等抑制作用。与这些合成化合物的结构比较,可以表明核苷8的糖部分和6-氨基侧链在生物活性中起重要作用。
