investigated in vitro for their abilities to inhibitselectively rat brain monoamineoxidase (MAO) B over MAO A. Most of them were MAO Binhibitors and those bearing a substituted 4-(arylmethoxy)phenyl group in the position 5 of the tetrazole ring had IC50 values between 8 microM for 18d and 2 nM for 16a (30 nM for lazabemide) with a selectivity toward MAO B of 37,000 for 16a. The reversibility of their
