Polyene compounds represented by the formula ##STR1## in which R is H, lower alkyl of from 1 to 8 carbon atoms or aralkyl; R.sub.1 is H or lower alkyl of from 1 to 5 carbon atoms; and Y is carboxy, alkoxycarbonyl, alkenyloxycarbonyl, aralkoxycarbonyl, tetrazolyl or ##STR2## wherein R is H, lower alkyl of from 1 to 8 carbon atoms or aralkyl; and pharmaceutically acceptable salts thereof. The foregoing compounds have been found active in regulating the formation of lipoxygenase and as such possess therapeutic value in the treatment of inflammatory conditions and allergic responses.
                            式为##STR1##的聚烯烃化合物,其中R为H,1至8个碳原子的低烷基或芳基烷基;R.sub.1为H或1至5个碳原子的低烷基;Y为羧基,烷氧羰基,烯烃氧羰基,芳基烷氧羰基,
四唑基或##STR2##,其中R为H,1至8个碳原子的低烷基或芳基烷基;以及其药学上可接受的盐。这些化合物已被发现在调节脂氧合酶的形成方面具有活性,因此在治疗炎症和过敏反应方面具有治疗价值。
