Salsalate
A dimeric benzoate ester obtained by intermolecular condensation between the carboxy of one molecule of salicylic acid with the phenol group of a second. It is a prodrug for salycylic acid that is used for treatment of rheumatoid arthritis and osteoarthritis and also shows activity against type II diabetes. — ChEBI
