Oxadiazoles of formula I
wherein one of X, Y and Z is an oxygen atom and the other two are nitrogen atoms, and the dotted circle represents aromaticity (two double bonds) thus forming a 1,3,4-oxadiazole or 1,2,4-oxadiazole nucleus; R¹ represents a non-aromatic azacyclic or azabicyclic ring system; and R² represents an optionally substituted saturated hyrocarbon group having at least three carbon atoms, or unsaturated hydrocarbon group having at least 6 carbon atoms, have particularly advantageous selective properties for use in the treatment and/or prevention of neurodegenerative diseases.
式I中的氧代唑,其中X、Y和Z中的一个是氧原子,另外两个是氮原子,虚线圈代表芳香性(两个双键),从而形成1,3,4-氧代唑或1,2,4-氧代唑核;R¹代表非芳香性的杂环或氮杂双环环系统;R²代表至少有三个碳原子的可选择取代的饱和碳氢基团,或至少有6个碳原子的不饱和碳氢基团,对于治疗和/或预防神经退行性疾病具有特别有利的选择性特性。
