Complexation of Zn arylporphyrinates with leucine methyl ester
Mamardashvili,Storonkina,Mamardashvili
, p. 388 - 392 (2004)
Extra coordination of L-leucine methyl ester with seventeen different Zn arylporphyrinates is studied by spectrophotometric titration and capability of Zn porphyrinates with the active OH groups to recognize LeiOCH3 in toluene at 20°C is determined. The formation of associates of the composition amino acid etherporphyrinate depending on the substituent positions in a macrocycle is studied by the 1H NMR method. The most strong donor-acceptor bonds between Zn porphyrinate and LeiOCH3 are observed in the case of pyridine-substituted porphyrins and porphyrins with phenyl rings containing electron-donor substituents in the m-position. The best recognizing capabilities with respect to leucine are shown by Zn porphyrinates with di- and tetra-4-OH-phenyl substitution in the meso-positions of a macrocycle.
Molecular recognition of α-amino acid esters with arylporphyrin zinc complexes
Mamardashvili,Storonkina,Mamardashvili
, p. 1446 - 1450 (2007/10/03)
The recognition ability of 10 arylporphyrin zinc complexes with respect to glycine, α-alanine, and leucine methyl esters in toluene at 20°C was studied by spectrophotometric titration. The formation of amino acid-porphyrin associates, depending on the sub
