C-phenyl 1-thioglucitol compounds of the following formula (I) or pharmaceutically acceptable salts thereof or hydrates thereof:
[wherein
X represents a hydrogen atom or a C1-6 alkyl group,
Y represents a C1-6 alkylene group or —O—(CH2)n- (wherein n represents an integer of 1 to 5), and
Z represents —CONHRA or —NHCONHRB (provided that when Z represents —NHCONHRB, n is not 1),
wherein
RA represents a C1-6 alkyl group substituted with 1 to 3 substituents selected from the group consisting of a hydroxyl group and —CONH2, and
RB represents a hydrogen atom or a C1-6 alkyl group substituted with 1 to 3 substituents selected from the group consisting of a hydroxyl group and —CONH2] 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.
以下式(I)的C-苯基1-硫基葡萄糖醇化合物或其药物可接受的盐或水合物:[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),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到3个从羟基和—CONH2组成的取代基所取代,而RB代表氢原子或C1-6烷基,其被1到3个从羟基和—CONH2组成的取代基所取代],因其对通过抑制SGLT1活性的糖(例如葡萄糖)吸收的抑制作用或者对通过抑制SGLT1和SGLT2活性的糖(例如葡萄糖)吸收和尿糖排泄作用的抑制作用,可用作糖尿病的预防或治疗剂。
