Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. Along with sodium salicylate (sc-3520), aspirin has been shown to block the long terminal repeat from the human immunodeficiency virus and the Ig κ enhancer from NFκB dependent transcription.
