Copper-catalyzed azide-alkyne [3 + 2] cycloaddition has been utilized for preparing a series of 1H-1,2,3-triazoles with the purpose of probing structure-activity relationships among a uracil-ferrocene-triazole conjugate family. The antitubercular evaluation studies revealed an improvement in activity with the introduction of a ferrocene nucleus among N-alkylazido-uracil precursors, with a preference
with the aim of evaluating their in vitro anti-proliferative efficacy on human leukemia (CCRF-CEM) and human breast adenocarcinoma (MDA-MB-468) cell lines. Cytotoxicevaluation studies identified a number of synthesized conjugates that inhibited the proliferation of leukemia cancer cells by ~70% after 72 h. The selected synthesized conjugates were found to be significantly less cytotoxic against normal
Huisgen的叠氮化物-炔烃环加成反应用于合成一系列1 H -1,2,3-三唑系尿嘧啶-二茂铁基查耳酮共轭物,旨在评估其对人白血病的体外抗增殖功效(CCRF-CEM)和人乳腺癌细胞(MDA-MB-468)。细胞毒性评估研究确定了许多合成的缀合物,可在72小时后将白血病癌细胞的增殖抑制约70%。当与CCRF-CEM癌细胞相比时,发现选择的合成缀合物对正常肾细胞系(LLC-PK1)的细胞毒性明显较小。 1 H -1,2,3-三唑系尿嘧啶-二茂铁基查尔酮偶联物的合成及其体外抗增殖功效对人白血病(CCRF-CEM)和人乳腺癌(MDA-MB-468)细胞系的影响。

regiospecifically transformed to 1,2,3-triazole derivatives, 17,18 and 19. Heating 1-(4-azidobutyl)-5-bromouracil (20) yielded 3,9-tetramethylene-8-azaxanthine (22). 9 with NBA gave 1,06-tetramethylene-5-bromo-6-hydroxy-5,6-dihydrouracil (24) and the 5-brominated analog of 9 (25). The 4-functionalized butyl side chain proved to serve as a substitute for the 5'-functionalized sugar moiety in pyrimidine ribonucleosides
