A series of phenothiazine carboxylic acid derivatives, having 6-amino-pyrimidine-2,4(1H,3H)-dione moiety via a appropriate linker, were synthesized and evaluated for their affinity toward human histamine H1 receptor and Caco-2 cell permeability. Selected compounds were further evaluated for their oral anti-histaminic activity in mice and bioavailability in rats. Finally, promising compounds were examined
合成了一系列通过适当的接头具有6-氨基-嘧啶-2,4(1 H,3 H)-二酮部分的吩噻嗪羧酸衍生物,并评估了它们对人组胺H 1受体和Caco-2的亲和力细胞通透性。进一步评估了所选化合物在小鼠中的口服抗组胺活性和在大鼠中的生物利用度。最后,在小鼠OVA诱导的双相皮肤反应模型中检查了有希望的化合物的抗炎潜力。在所测试的化合物中,吩噻嗪乙酸化合物27在体内模型中均显示出组胺H 1受体拮抗活性和抗炎活性。
