pyrazolo[3,4-d]pyrimidines tethered with nitric oxide (NO) producing functionality was designed and synthesized. Sulforhodamine B (SRB) protein assay revealed that NO releasing moiety in the synthesized compounds significantly decreased the cell growth more than the des-NO analogues. Compounds 7C and 7G possessing N-para-substituted phenyl group, released the highest NO concentration of 4.6% and 4.7%
设计并合成了一系列新的与一氧化氮(NO)连接的吡唑并[3,4-d]嘧啶类化合物。Sulforhodamine B(SRB)蛋白测定表明,合成的化合物中的NO释放部分比des-NO类似物明显减少了细胞生长。具有N-对位取代苯基的化合物7C和7G释放的最高NO浓度分别为4.6%和4.7%。与厄洛替尼作为参考药物(IC50)相比,合成化合物对HepG2细胞系的抗增殖活性分别将化合物7h,7p,14a和14b鉴定为IC50 = 3、5、3和5μM系列中最具细胞毒性的化合物。 =25μM)。流式细胞仪研究表明,7h使细胞处于细胞周期的G0 / G1期,而7p使细胞处于S期。而且,
