Abstract
Rabbit lung and heart show clorgyline-resistant benzylamine oxidase activity which is sensitive to semicarbazide (SSAO) and alpha-amino-guanidine. This SSAO activity is inhibited by pyridoxamine with an IC50 of 6.3 x -6 M for lung and of 1.1 x 10(-5) M for heart, the inhibition being non-competitive and only partially reversed by dialysis at 4 degrees C. Semicarbazide, alpha-aminoguanidine and pyridoxamine show a similar time-dependent type of inhibition of rabbit lung and heart SSAO.
