] are useful as prophylactic or therapeutic agents for diabetes, because of their suppressive effect on sugar (e.g., glucose) absorption through inhibition of SGLT1 activity, or alternatively, because of their suppressive effect on sugar (e.g., glucose) absorption and excretory effect on urinary sugars through inhibition of both SGLT1 and SGLT2 activities.
以下公式(I)的C-苯基1-硫代葡萄糖醇化合物或其药学上可接受的盐或水合物是糖尿病的预防或治疗药物,因为它们通过抑制SGLT1活性对糖(例如葡萄糖)吸收具有抑制作用,或者通过抑制SGLT1和SGLT2活性对糖(例如葡萄糖)吸收和尿糖排泄具有抑制作用。其中X代表氢原子或C1-6烷基,Y代表C1-6烷基或-O-(CH2)n-(其中n表示1至5的整数)的烷基,Z代表—CONHRA或—NHCONHRB(但当Z代表—NHCONHRB时,n不为1),其中RA代表C1-6烷基,其被1至3个取自氢氧基和—CONH2的基团取代,而RB代表氢原子或C1-6烷基,其被1至3个取自氢氧基和—CONH2的基团取代。
