Substituted alkadienes of formula: ##STR1## in which R.sub.1 is hydroxy or acetoxy, R.sub.2 is hydrogen, carboxy, alkoxycarbonyl, phenyl or benzoyl, and R.sub.3 is alkylthio or alkoxy and R.sub.4 is naphthoyl or optionally substituted benzoyl, or R.sub.3 is alkoxycarbonyl, cycloalkyloxycarbonyl or cyano and R.sub.4 is alkyl, naphthyl, optionally substituted phenyl, alkylthio, naphthylmethanethio, optionally substituted benzylthio, optionally substituted phenylthio, naphthylthio, phenethylthio or allylthio, or R.sub.3 and R.sub.4 form, with the carbon atom to which they are attached, a ring-system of formula: ##STR2## in which R.sub.5 is hydrogen or alkoxy and X is methylene or S inhibit 5-lipoxygenase and are useful, for example, as anti-inflammatories.
式子为:##STR1## 其中 R.sub.1 为羟基或乙酰氧基,R.sub.2 为氢、羧基、烷氧羰基、苯基或苯甲酰基,R.sub.3 为烷基硫醇或烷氧基,R.sub.4 为萘甲酰基或可选的取代苯甲酰基,或 R.sub.3 为烷氧羰基、环烷氧羰基或氰基,R.sub.4 为烷基、萘基、可选的取代苯基、烷基硫醇、萘基甲硫、可选的取代苯基甲硫、可选的取代苯基硫、萘基硫、苯乙基硫或烯丙基硫,或 R.sub.3 和 R.sub.4 与它们连接的碳原子形成一个环式系统,其式子为:##STR2## 其中 R.sub.5 为氢或烷氧基,X 为亚甲基或硫,这些化合物能抑制5-脂氧酶,例如作为抗炎药物。
