Abstract
The invention provides novel antiinflammatory and analgesic agents of the formulae The novel compounds have an improved inhibitory effect and/or less cytotoxicity in comparison with compounds known from the prior art. The compounds according to the invention are outstandingly suitable for preventing and/or treating disorders caused or partly caused by an increased activity of the enzyme phospholipase A2, such as, for example, inflammations, allergies, asthma, psoriasis and endotoxic shock.
