  Antihyperglycemic activity of novel substituted 3H-1,2,3,5-oxathiadiazole 2-oxides

  摘要：

  A series of substituted 3H-1,2,3,5-oxathiadiazole-2-oxides (6) was prepared and tested for antihyperglycemic activity in the db/db mouse, a model for type 2 (non-insulin dependent) diabetes mellitus. The oxathiadiazoles 6 were synthesized by a two-step sequence: treatment of a substituted acetonitrile (4) with hydroxylamine to give the corresponding amidoxime (5) and cyclization with thionyl chloride to yield 6. In terms of potency, the 2-naphthalenylmethyl group (as in compound 3) was found to be the optimal substituent in this series. Compound 3 was approximately 5 times more potent than ciglitazone (1).

  卤素取代的 2- 和 3-甲基苯并[b] 噻吩：使用 1H NMR 光谱分析和 1H{1H} 核 Overhauser 效应定位卤素取代基

  摘要：

  制备了 37 个卤代 2- 和 3-甲基-（或卤甲基）-苯并 [b] 噻吩，包括 17 个新化合物。通过对它们的 80 MHz 1 HNMR 光谱的全面分析 (LAOCOON) 和 1H{1H} NOE 测量，证实了其中 14 种的构成。通过这种方式，4-和6-溴-3-溴甲基苯并[b]噻吩的制备副产物最终显示为5-溴-3-溴甲基苯并[b]噻吩。当照射 3-甲基或卤代甲基取代基时，3-取代的苯并[b]噻吩在 H-4 处显示出比在 H-2 处更大的 NOE 增强因子。

  halogenomethyl)‐benzo [b]thiophenes, including 17 new compounds, were prepared. The constitution of 14 of these was confirmed by full analysis (LAOCOON) of their 80 MHz1HNMR spectra and by 1H1H} NOE measurements. In this way a by‐product from the preparation of 4‐ and 6‐bromo‐3‐bromomethylbenzo[b]thiophenes was shown conclusively to be 5‐bromo‐3‐bromomethylbenzo[b]thiophene. The 3‐substituted benzo[b]thiophenes showed
