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,其抑制假定的γ-分泌酶对APP的加工,因此可用于治疗或预防阿尔茨海默病。该化合物在更高物种(恒河猴)中具有良好的药代动力学特性,因此可以进行间歇性剂量(例如每周一次)的给药方案。在这种方案下,该化合物表现出显著且持续的Aβ降低,而不表现出与Notch相关的胃肠毒性,例如持续7天。还包括制药组合物和使用方法。
