The synthesis and chemical behaviour of pyrimidothiazine derivatives with a carboxyl group in position 7 [compounds (II) and (III)] or in position 6 [compounds (IV) and (V)] are described. It has been shown that these products, analogous with the isosteric benzothiazines, have the 5H-pyrimidothiazine structure. Compounds (II), (III) and (IV) show immunological activity, inhibiting passive cutaneous anaphyllaxis in the rat.
描述了在7位[化合物(II)和(III)]或6位[化合物(IV)和(V)]带有羧基的嘧啶并噻嗪衍生物的合成及化学性质。结果表明,这些与等排体苯并噻嗪类似的产物具有5H-嘧啶并噻嗪结构。化合物(II)、(III)和(IV)表现出免疫活性,可抑制大鼠的被动皮肤过敏反应。
