  N-Acetic acid derivatives (I) of 2-substituted 1, 4-benzoxazines and benzothiazines were designed and synthesized for evaluation as new aldose reductase inhibitors. In general, 3-thioxo derivatives were more potent inhibitors of aldose reductase from human placenta in vitro than the corresponding 3-oxo derivatives. While many compounds (I) were not very effective in inhibiting sorbitol accumulation in the rat sciatic nerve in vivo, the 3-thioxo compounds bearing an isopropyl group at the 2-position showed highly potent activity in the in vivo assay. Compound 46 (AD-5467) was selected from this series as a candidate for further development.

  N-乙酸衍生物（I）的2-取代基1,4-苯并恶嗪和苯并噻嗪被设计合成，以评估其作为新型醛糖还原酶抑制剂的潜力。一般而言，3-硫代羰基衍生物在体外对人胎盘醛糖还原酶的抑制活性比相应的3-氧代衍生物更强。虽然许多化合物（I）在体内对大鼠坐骨神经山梨醇积累的抑制作用并不十分有效，但在体内试验中，2-位带有异丙基的3-硫代羰基化合物显示出极强的活性。从这一系列中选出化合物46（AD-5467）作为进一步开发的候选药物。
