been synthesized. Their in vivo biological activity determined in rat and mouse delayed type hypersensitivity has been found to correlate well with their in vitro DHODH potency. The most promising compound (3) has shown activity in rat and mouse collagen (II)-induced arthritis models (ED50 = 2 and 31 mg/kg, respectively) and has shown a shorter half-life in man when compared with leflunomide. Clinical
新型免疫抑制剂来氟米特(1)的活性代谢物(2)已显示出抑制二氢乳清酸脱氢酶(DHODH)的作用。该酶催化从头进行嘧啶生物合成的第四步。已经合成了一系列活性代谢物2的类似物。已经发现它们在大鼠和小鼠迟发型超敏反应中的体内生物学活性与其体外DHODH效力密切相关。最有希望的化合物(3)在大鼠和小鼠胶原(II)诱导的关节炎模型中显示出活性(分别为ED50 = 2和31 mg / kg),与来氟米特相比,在人中的半衰期更短。类风湿关节炎的临床研究正在进行中。
