The present invention is directed to a novel trifluoromethylsulfonamide derivative which inhibits the processing of APP by the putative γ-secretase and thus is useful in the treatment or prevention of Alzheimer's disease. This compound possesses favorable pharmacokinetic properties in higher species (rhesus) and thus can be dosed on an intermittent dosing regiment (e.g., once weekly). When dosed on such a regiment the compound exhibits significant and continuous Aβ lowering without the manifestation of Notch associated gastrointestinal toxicity for extended periods, e.g., 7 days. Pharmaceutical compositions and methods of use are also included.
本发明涉及一种新型三
氟甲基磺酰胺衍
生物,其抑制了假定的γ-分泌酶对APP的加工,因此在治疗或预防阿尔茨海默病方面具有用途。该化合物在更高级别物种(恒河猴)中具有良好的药代动力学特性,因此可以采用间歇剂量方案(例如,每周一次)。在采用这种方案的情况下,该化合物表现出显著而持续的Aβ降低,而不会表现出与Notch相关的胃肠毒性,例如,7天。还包括制药组合物和使用方法。
