中文摘要: |
合成了一种新型1,2,4-噁二唑衍生物N-[2,6-二氯-4-(1,2,4-噁二唑-3-基)苯基]-2-甲氧基烟酰胺(C15H10Cl2N4O3),其结构通过1H NMR、13C NMR、HRMS以及X-射线单晶衍射进行表征。该晶体属于三斜晶系,P1空间群,晶胞参数a=7.1291(9)Å,b=8.4352(10)Å,c=14.0021(18)Å,α=73.834(3)°,β=77.407(3)°,γ=70.019(3)°,Mr=366.18,V=752.97(16)Å3,Z=2,Dc=1.611g/cm3,μ(MoKα)=0.454mm-1,F(000)=372.0,Rint=0.023。初步活性研究发现,该化合物对LoVo、A549、SK-BR-3和HeLa这四种肿瘤细胞株具有明显的抑制作用,尤其是对HeLa细胞的抑制活性与阳性药物5-氟尿嘧啶(5-FU)相当。 |
英文摘要: |
A novel 1,2,4-oxadiazol derivative N-(2,6-dichloro-4-(1,2,4-oxadiazol-3-yl) phenyl)-2-methoxynicotinamide (C15H10Cl2N4O3) was synthesized, and the structure was characterized by 1H NMR, 13C NMR, HRMS and single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P1 with a=7.1291 (9), b=8.4352 (10), c=14.0021 (18) Å, α=73.834 (3)°, β=77.407 (3)°, γ=70.019 (3)°, Mr=366.18, V=752.97 (16) Å3, Z=2, Dc=1.611 g/cm3, μ(MoKα)=0.454 mm-1, F(000)=372.0, and Rint=0.023. The preliminary biological results suggested that the titled compound has obvious inhibitory effect on LoVo, A549, SK-BR-3, and HeLa cell lines, especially the inhibitory activity on HeLa cells was comparable to the positive drug 5-fluorouracil (5-FU). |
