4-b]pyridine 5. Compound 5 was further cyclized with N-/O-propargylated pyrimidine derivatives under Sharpless conditions and obtained compounds 6 and 7, respectively. Each set of compounds 6 and 7 were alkylated with different alkyl halides and obtained respective products 8 and 9. All the products were screened for cytotoxicity against four human cancer cell lines such as A549-Lung (CCL-185), MCF7-Breast
从6-三氟甲基吡啶-2(1 H)酮2经选择性的O-制备了一系列新颖的吡唑并[3,4- b ]吡啶和嘧啶官能化的1,2,3-三唑衍生物8a - g和9a - g。烷基化,然后使用水合肼环化,获得6-(三氟甲基)-1 H-吡唑并[3,4- b ]吡啶-3-胺4。将化合物4重氮化,然后与叠氮化钠反应,得到3-叠氮基-6-(三氟甲基)-1 H-吡唑并[3,4- b ]吡啶5。化合物5在Sharpless条件下用N- / O-炔丙基化的嘧啶衍生物进一步环环化,分别得到化合物6和7。将每组化合物6和7用不同的烷基卤化物烷基化,得到各自的产物8和9。筛选了所有产品对四种人类癌细胞系(如A549-肺(CCL-185),MCF7-乳腺癌(HTB-22),DU145-前列腺(HTB-81)和HeLa宫颈癌(CCL-2))的细胞毒性,化合物9d,9e和9f已经证明了显示出有希望的活动。还对产品的抗微生物,抗生物
