oxidation of succinate. Anticonvulsant activity, as exhibited by protection against pentylenetetrazol-induced seizures, with substituted thiosemicarbazides and the corresponding cyclized oxadiazoles ranged from 30 to 90% at a dose of 100 mg/kg. The degree of protection afforded by these compounds, however, was unrelated to their ability to inhibit oxidation of pyruvate, α-ketoglutarate, and succinate.
合成,表征和测试了几种2,5-二取代的1,3,4-恶二唑在抑制大鼠脑匀浆的呼吸活动中的有效性。发现所有取代的恶二唑及其前体硫代氨基脲都可抑制烟酰胺和腺嘌呤二核苷酸(NAD)依赖性的丙酮酸和α-酮戊二酸的氧化,以及NAD依赖性的琥珀酸的氧化。预防性戊戊四唑诱发的癫痫发作表现出的抗惊厥活性是,取代的硫代氨基脲和相应的环化恶二唑在100 mg / kg的剂量范围内为30%至90%。然而,这些化合物提供的保护程度与其抑制丙酮酸,α-酮戊二酸和琥珀酸的氧化能力无关。
