(3-Carboxy-5-oxo-5H[1]benzopyrano[2, 3-b]pyridin-2-yl)acetic acid derivatives (3 and 4) were found to possess potent antiarthritic activity in the rat adjuvant arthritis model. The mode of action of these compounds differs from that of acidic antiinflammatory drugs. Various modifications in these compounds (e.g., elongation, removal, or substitution of the methylene group of the acetic acid moiety; and substitution of the benzene ring) were made in order to study the structure-activity relationships. However, it was found that the structural requirements for the compounds to show activity are rather severe.
(3-羧基-5-氧代-5H[1]苯并呋喃[2, 3-b]吡啶-2-基)醋酸衍生物(3和4)在大鼠佐剂性关节炎模型中表现出强效的抗关节炎活性。这些化合物的作用机制与酸性抗炎药物不同。为了研究结构-活性关系,对这些化合物进行了各种修饰(例如,延长、去除或替代醋酸基团的亚甲基;以及替代苯环)。然而,发现这些化合物表现活性的结构要求相当严格。
