NMDA-induced lethality in mice (an assay that is also specific for competitive and noncompetitive NMDA antagonists). Two of the compounds, cis-4-(phosphonomethyl)piperidine-2-carboxylic acid (11a) and cis-4-(3-phosphonoprop-1-yl)piperidine-2-carboxylic acid (11c) proved to be potent NMDA antagonists. 11a and 11c displaced [3H]CPP binding with IC50's of 95 and 120 nM, respectively, and both protected
我们最近准备了一系列3-和4-(膦酰基烷基)吡啶-和-哌啶-2-羧酸作为N-甲基-D-天冬氨酸(NMDA)偏好受体神经传递的拮抗剂。NMDA拮抗剂可以证明是有用的治疗剂,例如作为抗惊厥药,用于治疗神经退行性疾病例如阿尔茨海默氏病和预防在脑缺血期间发生的神经元损害。评价制备的化合物置换[3H] CPP结合的能力(一种测定表明对结合于NMDA受体的化合物具有选择性的测定)以及其阻断NMDA诱导的小鼠致死性的能力(该测定也具有特异性)适用于竞争性和非竞争性NMDA拮抗剂)。其中两种化合物 cis-4-(膦酰基甲基)哌啶-2-羧酸(11a)和cis-4-(3-膦酰基丙-1-基)哌啶-2-羧酸(11c)被证明是有效的NMDA拮抗剂。11a和11c分别以95和120 nM的IC50取代了[3H] CPP结合,并且都用MEDs(最小有效剂量,即五只动物中三只存活的剂量)保护了小鼠免受NMDA致死性。和40
