Abstract

Provided is a novel C-phenyl glycitol compound that may serve as a prophylactic or therapeutic agent for diabetes by inhibiting both SGLT1 activity and SGLT2 activity, thereby exhibiting a glucose absorption suppression action and a urine glucose excretion action. A C-phenyl glycitol compound represented by a formula (I) below (as figure 1) or a pharmaceutically acceptable salt thereof or a hydrate thereof wherein R1 and R2 are the same or different and represent a hydrogen atom, a hydroxyl group, a C1-6 alkyl group, a C1-6 alkoxy group or a halogen atom, R3 is a hydrogen atom, a C1-6 alkyl group, a C1-6 alkoxy group or a halogen atom, Y is a C1-6 alkylene group, -O-(CH2)n- (n is an integer of 1 to 4) or a C2-6 alkenylene group, provided that when Z is NHC(= NH)NH2 or -NHCON(R)RC, n is not 1, Z is -CONHRA, -NHC(=NH)NH2 or -NHCON(R)RC, (as figure 2).

Description

technical field [0001] The present invention relates to C-phenylglycitol compounds having inhibitory activity on sodium-dependent glucose cotransporter 1 (SGLT1) and sodium-dependent glucose cotransporter 2 (SGLT2). Background technique [0002] When people develop diabetes, fasting blood glucose levels show up as 126 mg / dL or higher. Some people have shown postprandial blood glucose levels as high as 140-200 mg / dL even though fasting blood glucose levels have dropped to within the normal range. Such a population is diagnosed with impaired glucose tolerance (hereinafter referred to as "IGT"). It has been recognized that the risk of cardiovascular disease can be reduced by delaying the onset of diabetes caused by IGT, and some supporting findings have been obtained. For example, the Da Qing IGT and diabetes study conducted in China in 1997 reported that the development of IGT into type II diabetes can be significantly inhibited by diet and exercise (see Pan XR, et al., Diab...
