for diamine oxidase (DAO) and the novel phenacyl derivatives (2) are obtained in satisfactory preparative yield; no enantioselectivity is observed with (11) as an enzyme substrate. Remarkably, the triamines (9) and (13) are not oxidized and, moreover, (9) acts as a notable inhibitor for the DAO catalysed oxidation of (4) and (5). Kinetic evidence relevant to the mechanism of DAO action is presented
二胺(6)-(8)和(11)可以作为二胺氧化酶(DAO)的可接受底物,并且可以令人满意的制备产率获得新型苯甲酰基衍生物(2);用(11)作为酶底物没有观察到对映选择性。显着地,三胺(9)和(13)没有被氧化,此外,(9)作为DAO催化的(4)和(5)的氧化的显着抑制剂。提出了与DAO作用机理有关的动力学证据,并根据DAO催化的氧化模型进行了讨论。
