The present invention relates to a fused aminodihydrothiazine derivative of formula (I): wherein R is hydrogen or C
1-6
alkyl, optionally substituted by one to five halogen atoms; n is 0, 1, 2 or 3; Ar is phenyl or a 5- or 6-membered heteroaromatic group containing 1, 2 or 3 N atoms, which Ar is optionally substituted by one to three substituents selected from hal, hydroxyl, —CN, C
1-6
alkyl, C
2-3
alkenyl, C
2-3
alkynyl,
C-6
alkoxy, C
3-6
cycloalkoxy and pyrazine, where C
1-6
alkyl and C
1-6
alkoxy are optionally substituted by one to three halogen atoms; and pharmaceutically acceptable salts thereof; which compound has an Aβ production inhibitory effect or a BACE1 inhibitory effect and is useful as a prophylactic or therapeutic agent for a neurodegenerative disease 1 caused by Aβ and typified by Alzheimer-type dementia.
本发明涉及一种公式(I)的融合氨基二氢噻唑衍生物:其中R是氢或C1-6烷基,可选地被一个至五个卤素原子取代;n是0、1、2或3;Ar是苯基或含1、2或3个N原子的5或6元杂芳族基团,其中Ar可选地被一个至三个选自卤素、羟基、—CN、C1-6烷基、C2-3烯基、C2-3炔基、C-6烷氧基、C3-6环烷氧基和吡嗪的取代基取代,其中C1-6烷基和C1-6烷氧基可选地被一个至三个卤素原子取代;以及药用可接受的盐;该化合物具有Aβ生成抑制效果或BACE1抑制效果,并且可用作预防或治疗由Aβ引起的神经退行性疾病1的预防或治疗剂,该疾病以阿尔茨海默症型痴呆为典型。
