The invention relates to compounds of the formula
wherein
Ris hydrogen, lower alkyl, -(CH₂)₂N(R³)₂ or -CH₂OOCR³ wherein R₃ is lower alkyl;
R¹is CH₃(CH₂)n-, wherein n is 9-17, or R⁴(CH₂)p-, wherein p is 3-10 and R⁴ is 1- or 2-naphthyloxy, 2,3- or 3,4-dihydroxyphenyl, 2,3- or 3,4-dibenzyloxyphenyl, phenyl, phenoxy, or substituted phenyl or phenoxy wherein the substituent is selected from the group consisting of hydroxy, benzyloxy, methylsulfinyl, methylsulfonyl or phenyl;
R²is R⁴(CH₂)p- , 1-adamantyl-CO- or diphenylmethyl-CO-, and, when R is hydrogen, a pharmaceutically acceptable salt with a base.
The compounds of formula I are potent inhibitors of phospholipases A₂ (PLA₂'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.
本发明涉及式如下的化合物
式中
R是氢、低级烷基、-(CH₂)₂N(R³)₂或-CH₂OOCR³,其中R₃是低级烷基;
R¹是 CH₃(CH₂)n-,其中 n 是 9-17,或 R⁴(CH₂)p-,其中 p 是 3-10,R⁴是 1-或 2-萘氧基、2,3-或 3,4-二羟基苯基、2,3-或 3,4-二苄氧基苯基、苯基、苯氧基或取代的苯基或苯氧基,其中取代基选自由羟基、苄氧基、甲亚磺酰基、甲磺酰基或苯基组成的组;
R²为 R⁴(CH₂)p-、1-金刚烷基-CO-或二苯基甲基-CO-,当 R 为氢时,为药学上可接受的碱式盐。
式 I 的化合物是磷脂酶 A₂(PLA₂)的强效抑制剂,因此可用于治疗疾病,如牛皮癣、炎症性肠病、哮喘、过敏、关节炎、皮炎、痛风、肺部疾病、心肌缺血和创伤引起的炎症,如脊髓损伤。
