The present invention relates to: (i) hydroxamic acid derivative of the formula (I): ##STR1## wherein R.sup.1 is hydrogen, or C1-4 alkyl; R.sup.2 is hydrogen, C1-8 alkyl, phenyl, C1-4 alkyl substituted by phenyl; E is --CONR.sup.3 --, in which R.sup.3 is hydrogen, C1-4 alkyl, etc., --NR.sup.3 CO--, --CO--O--, --O--CO--etc.; A is hydrogen, C1-8 alkyl, C3-7 cycloalkyl, or Ar; J is bond, C2-4 alkylene etc.; G is --(CH.sub.2).sub.m --, in which m is 2, 3 or 4, or ##STR2## in which R.sup.6 and R.sup.7 is hydrogen, C1-8 alkyl etc.; and non-toxic salts thereof, ii) processes for the preparation thereof, and iii) pharmaceutical agents containing them. The compounds of formula (I) are useful for prevention and/or treatment of diseases induced by overexpression or excess activity of gelatinases, for example, rheumatoid diseases, arthrosteitis, unusual bone resorption, osteoporosis, periodontitis, interstitial nephritis, arteriosclerosis, pulmonary emphysema, cirrhosis, cornea injury, metastasis of, invasion of or growth of tumor cells, autoimmune disease (Crohn's disease, Sjogren's syndrome), disease caused by vascular emigration or infiltration of leukocytes or arterialization in animals including human beings, especially human beings.
本发明涉及以下内容:(i)式(I)的羟肟酸衍生物:##STR1##其中R.sup.1为氢或C1-4烷基;R.sup.2为氢、C1-8烷基、苯基、C1-4烷基取代的苯基;E为--CONR.sup.3--,其中R.sup.3为氢、C1-4烷基等,--NR.sup.3 CO--,--CO--O--,--O--CO--等;A为氢、C1-8烷基、C3-7环烷基或Ar;J为键、C2-4烷基等;G为--(CH.sub.2).sub.m--,其中m为2、3或4,或##STR2##其中R.sup.6和R.sup.7为氢、C1-8烷基等;以及其非毒性盐,(ii)其制备方法,以及(iii)含有它们的药物制剂。式(I)的化合物对于预防和/或治疗由明胶酶过度表达或过度活性引起的疾病有用,例如风湿性疾病、关节炎、异常骨吸收、骨质疏松症、牙周炎、间质性肾炎、动脉硬化、肺气肿、肝硬化、角膜损伤、肿瘤细胞的转移、侵袭或生长、自身免疫性疾病(Crohn病、Sjogren综合征)、由动物包括人类的白细胞或动脉化引起的疾病。
