The most potent inhibitor is N-o-chlorobenzyl-N'N''-dimethylguanidine (B.W. 392C60) which inhibits MAO in vitro to the same extent as phenylisopropylhydrazine (PIH, JB516). This compound has been shown to be a competitive and reversible inhibitor of MAO. The significance of this MAO inhibition in the mechanism of action of these hypotensive guanidines is discussed.
