  New Azolidinediones as Inhibitors of Protein Tyrosine Phosphatase 1B with Antihyperglycemic Properties

  摘要：

  Insulin resistance in the liver and peripheral tissues together with a pancreatic cell defect are the common causes of type 2 diabetes. It is now appreciated that insulin resistance can result from a defect in the insulin receptor signaling system, at a site post binding of insulin to its receptor. Protein tyrosine phosphatases (PTPases) have been shown to be negative regulators of the insulin receptor. Inhibiton of PTPase may be an effective method in the treatment of type 2 diabetes. A series of azolidinediones has been prepared as protein tyrosine phosphatase 1B (PTP1B) inhibitors. Several compounds were potent inhibitors against the recombinant rat and human PTP1B enzymes with submicromolar IC50 values. Elongated spacers between the azolidinedione moiety and the central aromatic portion of the molecule as well as hydrophobic groups at the vicinity of this aromatic region were very important to the inhibitory activity. Oxadiazolidinediones 87 and 88 and the corresponding acetic acid analogues 119 and 120 were the best h-PTP1B inhibitors with IC50 values in the range of 0.12-0.3 mu M. Several compounds normalized plasma glucose and insulin levels in the ob/ob and db/db diabetic mouse models.

  Alkylation of ethyl 4-(2,5-dimethylthiophen-3-yl)-3-oxobutanoate with 2-aryl-4-bromoacetyl-5-methyl-1,3-oxazole followed by decarboxylation cyclization of the intermediate, diketo ester affords the title photochromic compounds. Relationship between the fluorescent characteristics, thermal stability of photoinduced form as well as quantum yields of photochemical reactions and the structure of these compounds was evaluated.
