  Na⁺-Glucose Cotransporter (SGLT) Inhibitors as Antidiabetic Agents. 4. Synthesis and Pharmacological Properties of 4‘-Dehydroxyphlorizin Derivatives Substituted on the B Ring

  摘要：

  In our studies of Na+-glucose cotransporter (SGLT) inhibitors as antidiabetic agents, a series of novel 4'-dehydroxyphlorizin derivatives substituted on the B ring was prepared and their effects on urinary glucose excretion were evaluated in rats. Introduction of only a small alkyl group at the 4'-position increased the activity, and 3-(benzo[b]furan-5-yl)-2',6'-dihydroxy-4'-methylpropiophenone 2'-O-beta-D-glucopyranoside (4) showed the most potent effect. To overcome hydrolysis of compound 4 by beta-glucosidase in the digestive tract, the OH groups on the glucose moiety of compound 4 were modified. Three prodrugs (5, 42, and 55) were more potent than the parent compound 4 by oral administration, and finally 3-(benzo[b]furan-5-yl)-2',6'-dihydroxy-4'-methylpropiophenone 2'-O-(6-O-methoxycarbonyl-beta-D-glucopyranoside) (5) was selected as a new promising candidate. Compound 5 was metabolized mainly by liver esterase to the active form (4), which was about 10 times more potent than 5 in inhibiting SGLT. In oral glucose tolerance test in db/db mice, compound 5 dose-dependently suppressed the elevation of glucose levels. Single administration of 5 reduced hyperglycemia concurrently with increase of glucose excretion into urine in diabetic KK-A(y) mice. Furthermore, compound 5 suppressed the elevation of blood glucose levels but did not lower it below the normal level even in fasted conditions in KK-A(y) mice. Additionally, long-term treatment with 5 dose-dependently reduced hyperglycemia and HbA1c in KK-A(y) mice. These pharmacological data strongly suggest that compound 5 has a therapeutic potential in the treatment of NIDDM.
