and 8a-h were screened against four human cancer cell lines (HeLa, COLO205, Hep G2 and MCF 7) and one normal cell line (HEK 293). Compounds 4e, 4f, 4g, 5h, 7c, 7d, 7e and 7f showed significant anticancer activity against all the cell lines at micro molar concentration and found to be non-toxic to normal cell line. Studies for HeLa, COLO205 and MCF-7 using CoMFA and CoMSIA. Models from 3D-QSAR provided
一系列新颖的呋喃并[2,3-b]吡啶-2-甲酰胺4a-h /吡啶并[3',2':4,5]呋喃并[3,2-d]嘧啶-4(3H)-衍生物由吡啶2(1H)1通过与α-溴乙基酯的选择性O-烷基化,然后环化,然后与不同的脂族伯胺反应获得4,再与原乙酸三乙酯/原甲酸三乙酯反应,制得5a-p。还制备了新颖的呋喃[2,3-b]吡啶-2-碳酰肼席夫碱7a-h和吡啶基[3',2':4,5]呋喃[3,2-d]嘧啶-4(3H)-衍生物8a-h由呋喃[2,3-b]吡啶羧酸酯衍生物3开始,与水合肼反应形成6,并与各种取代的醛反应并环化。针对4种人类癌细胞系(HeLa,COLO205,Hep G2和MCF 7)和一种正常细胞系(HEK 293)。化合物4e,4f,4g,5h,7c,7d,7e和7f在微摩尔浓度下对所有细胞系均表现出显着的抗癌活性,并且对正常细胞系无毒。使用CoMFA和CoMSIA研究HeLa,COLO2
