摘要: 以吡咯、p-甲氧基苯甲醛为原料,丙酸为溶剂,130℃ 条件下制得四(p-甲氧苯基)卟啉(TMOPP);然后在100℃ 微波辐射条件下,以TMOPP和乙酸铜为原料,DMF为溶剂,制得目标化合物四(p-甲氧苯基)卟啉铜(Ⅱ)配合物 (CuTMOPP)。采用电喷雾质谱、紫外光谱和红外光谱等分析方法对所合成的目标化合物进行了表征,目标化合物的理论值和实验值基本一致。进一步采用紫外光谱、CD光谱、FRET熔点实验、PCR-Stop实验考察了目标化合物与c-myc G4 DNA的相互作用,结果表明目标化合物可能与c-myc G4 DNA以静电方式结合,从而抑制其复制,进一步对其生物功能的影响还在研究中。

Abstract: 5,10,15,20-tetra(4-merhoxyphenyl)porphyrin (TMOPP) was synthesized from pyrrole and p-methoxybenzaldehyde in propanoic acid solution at 130℃. Then, TMOPP and 1,4-dibromobutane were mixed in DMF solution at 100℃ to prepare target complex(CuTMOPP) under microwave-assisted with the yield of 64.7% in 20 min. The target compound was characterized by using ESI-MS, UV and IR spectra. Further, the binding behaviour of CuTMOPP with c-myc G4 DNA was investigated via FRET melting point methods, as well as spectroscopy methods. The results indicated that the target compound CuTMOPP may bind c-myc G4 DNA by electrostatic binding mode, as a result, the replication of c-myc G4 DNA was blocked, and an evaluation of biological activity is now in progress.
