an earlier paper, we reported that novel prostaglandin D(2) (PGD(2)) receptor antagonists having the bicyclo[2.2.1]heptane ring system as a prostaglandin skeleton were a potent new class of antiallergic agents and suppressed various allergic inflammatory responses such as those observed in conjunctivitis and asthma models. In the present study, we synthesized PGD(2) receptor antagonists having the 6
在较早的论文中,我们报道了以双环[2.2.1]庚烷环系统为前列腺素骨架的新型前列腺素D(2)(PGD(2))受体拮抗剂是一种有效的新型抗过敏剂,可抑制各种过敏性炎症诸如在结膜炎和哮喘模型中观察到的反应。在本研究中,我们合成了具有6,6-二甲基双环[3.1.1]庚烷环系统的PGD(2)受体拮抗剂。与具有磺酰胺基的双环[2.2.1]庚烷环系统的那些相反,这些衍生物具有酰胺部分。具有6,6-二甲基双环[3.1.1]庚烷环的衍生物在PGD(2)受体结合和cAMP形成分析中也显示出强大的活性。在诸如过敏性鼻炎,结膜炎和哮喘模型等体内分析中,这些系列的衍生物显示出优异的药理特性。特别地,化合物45在过敏性鼻炎和哮喘模型中也有效抑制了嗜酸性粒细胞的浸润。该化合物(45,S-5751)现在正被开发为一种有前途的抗过敏药物候选物。
