“…Organotin compounds have been shown to have high antitumor activity in vitro in a wide variety of human tumors. − The increasing interest in the chemistry and biochemistry of organotin complexes has led to extend studies on their interactions with different naturally occurring ligands, for example, carbohydrates, nucleic acid derivatives, amino acids, and peptides. ,,− Several papers have revealed the coordination behavior of organotin cations toward biomolecules containing different types of donor atoms including both solid state and solution studies. − …”

The formation constants of the species formed in the systems H þ þ dimethyltin(IV) þ tyrosine, tryptophan, and phenylalanine as well as H þ þ tyrosine, tryptophan, and phenylalanine have been determined in aqueous solution in the pH range (1.5 to 9.5) at a constant temperature (25 °C) and constant ionic strength (0.1 mol 3 dm À3 NaClO 4 ), using a combination of spectrophotometric and potentiometric techniques. The composition of the formed complexes were determined, and it was shown that dimethyltin(IV) forms three mononuclear 1:1 species with all the ligands, of the type MHL, ML, and MH À1 L, where M and L represent metal ion and each amino acid, respectively. A complex distribution curve depending on the pH and metalÀligand ratio is given, and influences of the ligands side chains on the stability constants of the formed species are discussed. 1 H NMR investigations in aqueous solution confirmed the species formation and led us to propose their probable structures.
