Novel prostaglandin D(2) (PGD(2)) receptor antagonists were synthesized as a potential new class of antiallergic agents having a bicyclo[2.2.1]heptane ring system with sulfonamide groups. Some of them exhibit extremely potent antagonism of the PGD(2) receptor in radioligand binding and cAMP formation assays with IC(50) values below 50 nM and much less antagonism of TXA(2) and PGI(2) receptors. These
新型前列腺素D(2)(PGD(2))受体拮抗剂被合成为具有磺酰胺基团的双环[2.2.1]庚烷环系的潜在新型抗过敏药。它们中的一些在放射性配体结合和cAMP形成分析中显示PGD(2)受体的强效拮抗作用,IC(50)值低于50 nM,而TXA(2)和PGI(2)受体的拮抗作用小得多。这些有效的PGD(2)受体拮抗剂经口服给予后,可显着抑制各种变应性炎症反应,例如变应性鼻炎,结膜炎和哮喘模型中血管通透性的增加。最初在我们实验室中合成的PGD(2)受体拮抗剂的优异药理学特征具有潜在的重大临床意义。
