Compounds of the formula ##STR1## wherein R is hydrogen, alkyl.sub.1-8, geminal alkyl.sub.1-3, unsubstituted or substituted aryl; X is alkylene, --CR.sub.1 .dbd.CR.sub.2 -- (E and/or Z), carbonyl, oxygen or sulfur, wherein one of R.sub.1 and R.sub.2 is alkyl.sub.1-3 and the other is hydrogen; Y is unsubstituted alkyl.sub.1-12 or substituted by one or more alkyl.sub.1-3 groups, or unsubstituted or substituted phenylalkyl .sub.1-3 ; or a salt thereof with a pharmaceutically acceptable base, are described. The compound of formula I are potent inhibitors of phospholipase A.sub.2 (PLA.sub.2) and are therefore useful in the treatment of inflammatory diseases, such as, psoriasis, inflammatory bowel disease, asthma, allergy, arthritis, dermatitis, gout, pulmonary, myocardial ischemia and trauma induced inflammation, such as, spinal cord injury.
化合物的公式为##STR1##其中R是氢,烷基.sub.1-8,双重烷基.sub.1-3,未取代或取代的芳基; X是烷基,--CR.sub.1 .dbd.CR.sub.2 --(E和/或Z),羰基,氧或硫,其中R.sub.1和R.sub.2中的一个是烷基.sub.1-3,另一个是氢; Y是未取代的烷基.sub.1-12或被一个或多个烷基.sub.1-3基团取代的,或未取代或取代的苯基烷基.sub.1-3; 或其与药学上可接受的碱盐。公式I的化合物是磷脂酶A.sub.2(PLA.sub.2)的强效抑制剂,因此在治疗炎症性疾病(如牛皮癣,炎症性肠病,哮喘,过敏,关节炎,皮炎,痛风,肺部,心肌缺血和创伤引起的炎症,如脊髓损伤)中有用。
