Synthesis and photodynamic action of porphyrin-cholesterol esters and their metal complexes was written by Huang, S. Q.;Liu, D. W.;Jiang, Z. C.;Guo, Y.;Li, B.. And the article was included in Yaoxue Xuebao in 1989.Synthetic Route of C47H36N4O The following contents are mentioned in the article:
The synthesis of cholesterol-porphyrin esters and their metal complexes were reported. Their cytotoxicity to cancer cell on exposure to light was also described. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Synthetic Route of C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Attachment of the ligand to the metal may be through a single atom, in which case it is called a monodentate ligand, or through two or more atoms, in which case it is called a didentate or polydentate ligand. Precious metals and metal oxides on carrier materials are used in many industrial processes as heterogenous catalysts.Synthetic Route of C47H36N4O
