investigated in vitro for their abilities to inhibit selectively rat brain monoamine oxidase (MAO) B over MAO A. Most of them were MAO B inhibitors 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
合成了二十个新的2-(氰基烷基)四唑(15和16)和二十个新的2-(羟烷基)四唑(17和18),并在体外研究了其抑制MAO A选择性抑制大鼠脑单胺氧化酶(MAO)B的能力。它们中的大多数是MAO B抑制剂,在四唑环5位带有取代的4-(芳甲氧基)苯基的那些,其IC50值在18d时为8 microM,在16a时为2 nM(拉扎贝胺为30 nM),具有选择性。朝向37,000的MAO B(16a)。通过体外透析试验证明了其抑制活性的可逆性。5- [4-(苯基甲氧基)苯基] -2-(2-氰乙基)四唑(16a)及其衍生物16h和5- [4-(苯基甲氧基)苯基] -2-(2-羟乙基)四唑(18a)发现其衍生物18h是有效的,体外选择性和竞争性MAO B抑制剂。Tetrazole 16a可以被认为是迄今为止已知的最具活性和选择性的竞争性MAO B抑制剂之一。选择该化合物用于离体实验,并显示为强效和可逆的MAO
