The present disclosure relates to benfotiamine derivatives, a method for preparing the same and a pharmaceutical composition, as indicated below, comprising the same. In the present disclosure, when the ortho position of benzene ring is only a halogen atom or an ethoxy substitution, or the meta position is only a bromine 5 atom, a chlorine atom, a fluorine atom or a nitro substitution, or the para position is only a chlorine atom, a methoxy substitution or a nitro substitution, its compound has a significant inhibition effect on Aβ40 and Aβ42. Furthermore, when the ortho position of benzene ring is only a fluorine atom or a bromine atom substitution, the compound has an outstanding inhibition effect on Aβ40 and Aβ42.
本公开涉及苯福酮衍生物、其制备方法和包含其的药物组合物,如下所示。在本公开中,当苯环的邻位仅为卤素原子或乙氧基取代,或间位仅为溴原子、氯原子、氟原子或硝基取代,或对位仅为氯原子、甲氧基取代或硝基取代时,其化合物对Aβ40和Aβ42具有显著的抑制作用。此外,当苯环的邻位仅为氟原子或溴原子取代时,该化合物对Aβ40和Aβ42具有卓越的抑制作用。
