Synthesis and DNA-binding studies of new cationic guanidine and betaineamide tetraphenylporphyrins
摘要:
Cationic water-soluble tetraphenylporphyrins with guanidine or betaine groups on the phenyl rings are prepared by the coupling reaction of hydrogen cyanamide and N-chlorobetainylchloride, respectively, with tetraaminophenylporphyrins and the preliminary report of their affinities for ct-DNA is described.
