A series of novel 2-((1-substituted-1H-1,2,3-triazol-4-yl/3-substitutedisoxazol-5-yl)methoxy) substituted pyridine,
1-((1-substituted-1H-1,2,3-triazol-4-yl/3-substitutedisoxazol-5-yl)methyl)substituted pyridin-2(1H)-one was prepared
from 2-oxo-6-phenyl/methyl-4-(trifluoromethyl)-1,2-dihydropyridine-3-carbonitrile 3 via propargylation followed by 1,3-
dipolar cycloaddition of the propargyl derivatives 4 and 5. These triazole/isoxazole tagged pyridine derivatives were
evaluated for antitumor activity against breast cancer cell lines such as MDA-MB-231, MCF-7 etc. The results indicated
that compounds 6e, 6f, 8e and 8f were found to be active on MDA-MB-231, while 6h and 8h were active on MCF-7.
一系列新型2-((1-取代的1H-1,2,3-三唑-4-基/3-取代的异恶唑-5-基)甲氧基)取代的吡啶、1-((1-取代的1H-1,2,3-三唑-4-基/3-取代的异恶唑-5-基)甲基)取代的吡啶-2(1H)-酮,从2-氧代-6-苯基/甲基-4-(三氟甲基)-1,2-二氢吡啶-3-氰化物3经炔丙基化,随后进行炔丙基衍生物4和5的1,3-偶极环加成反应制备。这些三唑/异恶唑标记的吡啶衍生物对乳腺癌细胞系如MDA-MB-231、MCF-7等进行抗肿瘤活性评估。结果表明,化合物6e、6f、8e和8f对MDA-MB-231有活性,而6h和8h对MCF-7有活性。
