[The interaction of organophosphorus amino acid analogs with cytochrome P-450 2B4].
Interaction between phosphorus amino acids analogs, 1-aminoalkylphosphonous and 1-aminoalkylthiophosphonic acids, and microsomes from the liver of phenobarbital-induced rabbits was studied. The phosphorus amino acids analogs cause type I and reverse type I spectral changes, respectively. A new reaction in the microsomal monooxygenase system was revealed. In the presence of NADPH, 1-aminoalkylphosphonous acids can be transformed to the corresponding 1-aminoalkylphosphonic acids by the reaction P-H-->P-OH. The reaction was monitored by 1H-NMR spectroscopy. 1-Aminoalkylphosphonous acids also serve as substrates for the NADPH-dependent monooxygenase system. 31P-NMR has shown that the oxidative desulfuration produces 1-aminoalkylphosphonous acids according to the reaction P=S-->P=O. Neither 1-aminoalkylphosphonous nor 1-aminoalkylphosphonic acids are deaminated in the NADPH-dependent monooxygenase system as follows from 1H-NMR spectroscopy.
