第一种底物样,可逆抑制剂,具有不同的铜胺氧化酶(CAO),IC50(M)低至2.0 x 10(-8),对应于4-氨基甲基吡啶与烷氧基(1a-d),烷硫基(2a,b)的衍生物已经制备并研究了在3和5位的烷基氨基(3a-e,4a-j)基团。抑制剂1a-d对苄胺氧化酶和氨基脲敏感的胺氧化酶具有活性,并且对二胺氧化酶,赖氨酰氧化酶和单胺氧化酶具有很高的选择性。抑制剂2a,b对苄胺氧化酶具有选择性,而抑制剂2a也是新型的二胺氧化酶的良好底物。抑制剂3a-e和4a-j是各种CAO的底物状,可逆的非选择性抑制剂,包括豌豆幼苗胺氧化酶和汉逊酵母多形胺氧化酶,从X射线结构测定中可以知道其酶促位点。抑制剂3b,c和4b,c是用于研究将提供适合X射线结构测定的晶体的CAO与来自哺乳动物的CAO相关联的出色的类似基质的工具。
The key reagent 3,5-dichloro-4-pyridinecarbonitrile (1) was used to synthesize 4-aminomethylpyridine derivatives 3,5-disubstituted with various amino groups, very active as inhibitors of diamine oxidase. The study of the reaction allowed to discover conditions for the gradual substitution in good yields of the two chlorine atoms to give symmetrically and unsymmetrically disubstituted derivatives (3), or the substitution of the cyano group, or the formation of amidines. The reduction of the cyano to aminomethyl group in compounds (3) afforded the target bioactive products.

Alkylamino Derivatives of 4-Aminomethylpyridine as Inhibitors of Copper-Containing Amine Oxidases
lysyl oxidase, and monoamine oxidases. The inhibitors 2a,b are selective for benzylamine oxidase whereas 2a is also a new type of good substrate of diamine oxidase. The inhibitors 3a-e and 4a-j are substratelike, reversible, nonselective inhibitors of various CAOs including peaseedlingamineoxidase and Hansenula polymorpha amineoxidase, whose enzymatic sites are known from X-ray structure determinations
