The invention relates to the use of substituted benzamide derivatives of Formula I: Wherein: A
1
and A
2
are —N or —CH, so that if A
1
is —N, then A
2
is —CH and If A
2
is —N, then A
1
is —CH; R is a hydrogen atom, or represents branched or unbranched —(C

The substituted benzamide derivatives of Formula I, their pharmaceutically acceptable salts, isomers or mixtures thereof are useful for the manufacture of a medicament for prevention and treatment of acute and chronic neurological disorders, cognitive and neurodegenerative diseases, more precisely for the manufacture of a medicament for prevention and treatment of neurodegenerative disorders such as Parkinson's Disease and Alzheimer's Disease.
本发明涉及使用式I的取代苯甲酰胺衍生物,其中:A1和A2为—N或—CH,如果A1为—N,则A2为—CH,如果A2为—N,则A1为—CH;R为氢原子,或代表支链或直链—(C1-C3)-烷基,—(C1-C3)-烷基,其中一个、两个或三个氢原子可以被卤素或羟基取代,—(C1-C3)—O—(C1-C3),—(C1-C3)—O—(C1-C3),其中一个、两个或三个氢原子可以被卤素取代,或R为一组,其中R3和R4都一起或独立地是卤素、羟基、—(C1-C3)烷基,其中一个、两个或三个氢原子可以被卤素或羟基取代,—O—(C1-C3)-烷基,—O—(C1-C3)-烷基,其中一个、两个或三个氢原子可以被卤素取代,—O—((C1-C3)—O—(C1-C3),—O—(C1-C3)—O—(C1-C3),其中一个、两个或三个氢原子可以被卤素取代;R1和R2都一起或独立地是卤素、羟基、—(C1-C3)-烷基,—(C1-C3C)-烷基,其中一个、两个或三个氢原子可以被卤素或羟基取代,—O—(C1-C3)-烷基,—O—(C1-C3)-烷基,其中一个、两个或三个氢原子可以被卤素取代,—O—(C1-C3)—O—(C1-C3),-0-(C1C3)—O—(C1C3),其中一个、两个或三个氢原子可以被卤素取代;它们的药学上可接受的盐、异构体或其混合物作为体外选择性MAO-B抑制剂。式I的取代苯甲酰胺衍生物、它们的药学上可接受的盐、异构体或其混合物,用于制造用于预防和治疗急性和慢性神经系统疾病、认知和神经退行性疾病的药物,更精确地用于制造用于预防和治疗神经退行性疾病,如帕金森病和阿尔茨海默病的药物。
