Objective To synthesize manganese porphyrin triple helix forming oligonucleotide acridine compound. Methods TFO containing 7 deaza 2′ deoxyxanthosine was synthesized with special oxidizing agent. Acridine and amino modifier C6 were bound to the 3′ end and the 5′ end of the oligonucleotide, respectively. After metallation and esterification of meso tetrakis(4 carbocyphenyl), it was bound to the 5′ end of the previously described oligonucleotide. The reaction product was separated and purified by thin layer chromatography(TLC), and then identified by mass spectrography and ultraviolet absorption spectrometry. Results Thin layer chromatography showed that there was a yellow acridine oligonucleotide band before the control oligonucleotide. Ultraviolet absorption spectrum analysis revealed that the manganese porphyrin triple helix forming oligonucleotide acridine compound possessed both characteristic absorption peaks of oligonucleotide at wavelength 260 nm and manganese porphyrin at wavelength 468 nm. Mass spectrogram confirmed that the practically detected molecular weight of the observed mass of TFO derivative was the same as the theoretical value. Conclusion Manganese porphyrin triple helix forming oligonucleotide acridine compound is synthesized successfully.
