Malonoben

Malonoben (also known as tyrphostin A9, SF-6847, GCP5126, and AG-17) is an uncoupling agent/protonophore. As of 1974 when it was discovered, it was considered the most powerful agent of this type, with a potency over 1800 times that of 2,4-dinitrophenol - the prototypical uncoupling agent - and about 3 times the effectiveness of 5-chloro-3-tert-butyl-2'-chloro-4'-nitrosalicylanilide.
