And the article was included in Chemische Berichte in 1995.Application of 57412-08-5 The following contents are mentioned in the article:

Twelve porphyrin ligands and their Pt(II) complexes were synthesized and characterized. Nine of the porphyrins are derived from hemin, and three are based on tetraphenylporphyrin. The ligands were transformed into diammine-dicarboxylatoplatinum(II) complexes and diamine-dichloroplatinum(II) complexes. The antitumor activity in the photodynamic therapy of the ligands and their complexes was tested in vitro towards the MDA-MB-231 mammary carcinoma cell line. The results obtained showed an additive effect on the photodynamic activity of the porphyrin skeleton when irradiation with visible red light and the cytotoxic activity of the Pt moiety in the complexes. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Application of 57412-08-5).

4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands.

Conformations of organic compounds in solution relate to their phys. and chem. properties and biol. activities. Two calix[4]arene-porphyrin derivatives were synthesized as models of cytochrome P 450 monooxygenase.

The synthesis of covalently linked tetraarylporphyrin dimers was written by Little, Robert G.. And the article was included in Journal of Heterocyclic Chemistry in 1978.SDS of cas: 57412-08-5 The following contents are mentioned in the article:

Porphyrin dimers, e.g. I, were prepared The synthesis involves the reaction of dibromoalkanes with phenolic porphyrins, such as 5-(4-hydroxyphenyl)-10,15,20-tritolylporphyrin, to form ¦Ø-bromoalkyl porphyrin ethers. The latter compounds are then reacted with a second phenolic porphyrin to give porphyrin dimers. A mixed metalloporphyrin dimer was prepared which contains both V(IV) and Cu(II). The compounds were examined spectroscopically. The free-base porphyrin dimers show a splitting of the intense Soret band. This is interpreted as indicative of weak singlet energy transfer between the covalently linked porphyrins. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5SDS of cas: 57412-08-5).

The electrospray ionization tandem mass spectrometry of 3 tetraphenylporphyrin derivatives containing hydroxyl group (HPTPP) was studied. The proposed fragmentation pathways were summarized. The fragments with the loss of active hydroxyl group or hydroxylphenyl group were observed only in the fragmentation pathway of HPTPP and the fragmentation of the porphyrin with electron – withdrawing substituents at Ph group was easier than that of the porphyrin electron – donating substituents at Ph group. It seemed that the substituents at Ph group in porphyrin had some effects on their fragmentation.
