Twenty new 2-(cyanoalkyl) tetrazoles (15 and 16) and twenty new 2-(hydroxyalkyl) tetrazoles (17 and 18) were synthesized and investigated in vitro for their abilities to inhibit selectively rat brain monoamine oxidase (MAO) B over MA0 A. Most of them were MA0 B inhibitors and those bearing a substituted 44arylmethoxy) phenyl group in the position 5 of the tetrazole ring had IC50 values between 8 pM for 18d and 2 nM for 16a (30 nM for ...
