A series of 4-substituted-2-thiazolylhydrazone derivatives have been synthesized and tested in vitro for their human monoamine oxidase (hMAO) A and B inhibitory activity. Our findings confirmed that the substitution at C4 of the thiazole ring was important to obtain highly potent and selective hMAO-B inhibitors with IC50 values in the nanomolar range. Moreover, these derivatives were endowed with a reversible mechanism of enzyme inhibition. Molecular modelling studies were performed to rationalize the recognition of all inhibitors with respect to hMAO-A and -B isoforms.
