The invention relates to compounds of the formula ##STR1## R is hydrogen, lower alkyl, --(CH.sub.2).sub.2 N(R.sub.3).sub.2 or --CH.sub.2 OOCR.sub.3 wherein R.sub.3 is lower alkyl; R.sub.1 is CH.sub.3 (CH.sub.2).sub.n --, wherein n is 0-17, or R.sub.4 (CH.sub.2).sub.p --, wherein p is 2-18 and R.sub.4 is 1- or 2-naphthyloxy, 2,3- or 3,4-dihydroxyphenyl, phenyl, phenoxy, or substituted phenyl or phenoxy wherein the substituent is selected from the group consisting of hydroxy, benzyloxy, methylsulfinyl, methylsulfonyl or phenyl; R.sub.2 is R.sub.4 (CH.sub.2).sub.p --, 1-adamantyl--CO-- or diphenylmethyl--CO--, and, when R is hydrogen, pharmaceutically acceptable salts with bases. The compounds of formula I are potent inhibitors of phospholipases A.sub.2 (PLA.sub.2 's) and are therefore useful in the treatment of diseases, such as psoriasis, inflammatory bowel disease, asthma, allergy, arthritis, dermatitis, gout, pulmonary disease, myocardial ischemia, and trauma induced inflammation, such as spinal cord injury.
该发明涉及以下结构的化合物:##STR1## 其中R为氢、较低的烷基、--(CH.sub.2).sub.2 N(R.sub.3).sub.2或--CH.sub.2 OOCR.sub.3,其中R.sub.3为较低的烷基;R.sub.1为CH.sub.3(CH.sub.2).sub.n--,其中n为0-17,或R.sub.4(CH.sub.2).sub.p--,其中p为2-18,R.sub.4为1-或2-萘氧基、2,3-或3,4-二羟基苯基、苯基、苯氧基,或取代的苯基或苯氧基,其中取代基选自羟基、苄氧基、甲基亚砜基、甲基砜基或苯基;R.sub.2为R.sub.4(CH.sub.2).sub.p--,1-金刚烷基--CO--或二苯甲基--CO--,当R为氢时,与碱形成的药用盐。式I的化合物是磷脂酶A.sub.2(PLA.sub.2's)的有效抑制剂,因此在治疗疾病如牛皮癣、炎症性肠病、哮喘、过敏、关节炎、皮炎、痛风、肺部疾病、心肌缺血以及创伤诱发的炎症(如脊髓损伤)中有用。
