2-(2-Benzylamine)-6-[(2-benzylamine)amino]-5-nitro-1H-benzo[de]-isoquinoline-1,3(2H)-dione (BBNID, 3) was synthesized and then characterized by FT-IR, NMR and elemental analysis. The crystal structure of BBNID was investigated using X-ray diffraction and SHELXTL97 software and the result indicated that BBNID crystallized in the monoclinic system, space group C2/c with a = 8.8032 (14), b = 8.822 (2), c = 13.994 (4) Å, V = 1005.9 (4) Å3; Z = 2. The free radical scavenging activity screening results showed that BBNID exhibited better scavenging activity than the commercial antioxidant BHT against 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•), with IC50 of 43.10 μM.
合成了 2-(2-苄基胺)-6-[(2-苄基胺)氨基]-5-硝基-1H-苯并[de]-异喹啉-1,3(2H)-二酮(BBNID,3),并通过傅立叶变换红外光谱、核磁共振和元素分析对其进行了表征。利用 X 射线衍射和 SHELXTL97 软件研究了 BBNID 的晶体结构,结果表明 BBNID 的晶体为单斜晶系,空间群为 C2/c,a = 8.8032 (14),b = 8.822 (2),c = 13.994 (4) Å,V = 1005.9 (4) Å3; Z = 2。自由基清除活性筛选结果表明,BBNID 对 2,2-二苯基-1-苦基肼自由基(DPPH-)的清除活性优于商业抗氧化剂 BHT,IC50 为 43.10 μM。
