Synthesis of some new pyrazolo[3,4- d ]pyrimidine derivatives using readily available starting materials are described. A one-pot multi component cyclocondensation reaction was used to prepare the novel 3-methyl-4-aryl-1-phenyl-1 H -pyrazolo[3,4- d ]pyrimidine-6-thiol which served as a new starting material for all new compounds in this research. The anti-microbial activities of the selective synthesized

elemental analysis in certain cases. Antitumor activities as a trial to obtain more effective and less toxic agents were evaluated. The antitumor activity results indicated that the selected tetrahydroacridinederivatives showed antitumor activity against the liver cancer (HEPG2) tumor cell line tested, but with varying intensities in comparison to the known anticancer drugs, 5-fluorouracil and doxorubicin
这项研究旨在合成和评估许多9-取代的四氢ac啶衍生物的化学治疗活性。起始原料a啶酰肼可通过环己酮和邻氨基苯甲酸之间的相互作用,然后将产物氯化,然后将最后一种化合物与水合肼缩合来制备。新化合物的结构由IR建立,1在某些情况下,还需要1 H NMR,MS光谱和元素分析。评价了抗肿瘤活性,以期获得更有效和毒性更低的药物。抗肿瘤活性结果表明,所选的四氢ac啶衍生物对测试的肝癌(HEPG2)肿瘤细胞系具有抗肿瘤活性,但与已知的抗癌药物5-氟尿嘧啶和阿霉素相比强度不同。已发现化合物VIb对肝癌(HEPG2)呈剂量依赖性,活性最高,并具有明显的生长抑制作用(浓度为0.694μg/ ml),而化合物XVIIIa在生长抑制活性方面排名第二(2.97) μg/ ml浓度)。
