title: Hypoglycemic activity of MTP-1403 (2-amino-7,8-dihydro-4-piperazinyl-6H-thiopyrano 3,2-d pyrimidine), a new hypoglycemic agent.
abstract: 2-Amino-7,8-dihydro-4-piperazinyl-6H-thiopyrano 3,2-d pyrimidine (MTP-1403) is a new oral hypoglycemic agent structurally different from any existing hypoglycemic drugs. MTP-1403 lowered fasting plasma level and dose-dependently improved glucose tolerance test without increasing insulin secretory response to glucose. MTP-1403 caused a decrease in fasting plasma glucose level in mild alloxan-induced diabetic rats but not in the rats suffering from ketosis. MTP-1403 markedly improved the oral glucose tolerance test in the genetically diabetic KK mice. These results suggest that hypoglycemic activity of MTP-1403 may be mechanically different from sulfonylureas and biguanides and beneficial to type II diabetics with hyperinsulinemia and insulin resistance.
