4-dihydro-4-oxo-5,6-cyclohexano-3-[[5-(trifluoromethyl) benzothiazol-2-yl]-methyl]-1-pyridazineacetic acid (82) are potent aldose reductase inhibitors with IC50s of 30, 2.1, 5, and 52.2 nM, respectively. The best of these compounds, 79 and 82, also inhibit accumulation of sorbitol in rat sciatic nerve in a model of diabetic complications, when administered orally at 10 mg/kg. The inhibition values are
zopolrestat(1a)及其同类物中的苯并噻唑侧链已被引入到邻苯二甲酰氧乙酸替代品中,包括吲哚,哒嗪酮和带有吡啶侧基的吡啶并哒嗪酮。所得化合物中有效的醛糖还原酶抑制活性与早期的zopolrestat系列产品一样广泛,因此进一步支持了我们的假设,即醛糖还原酶上有一个与苯并噻唑具有强亲和力的结合位点。代表性的新化合物1-[((5,7-二氟-2-苯并噻唑基)-甲基] -1H-吲唑乙酸(62),[6-[[5-(三氟甲基)苯并噻唑-2-基]甲基] -8-氧代-6H-吡啶并[2,3-d]-哒嗪-5-基]乙酸(70),3,4-二氢-4-氧代-5,6-二甲基-3-[(5,7-二氟苯并噻唑(-2-基)甲基] -1-哒嗪乙酸(79)和3,4-二氢-4-氧代-5,6-环己-3--3-[[5-(三氟甲基)苯并噻唑-2-基]-甲基] -1-哒嗪乙酸(82)是有效的醛糖还原酶抑制剂,IC50分别为30、2.1、5和52
