Two classes of diuretics (thiazide and loop) share structure similarities. Hydrochlorothiazide and furosemide have conserved phenol rings with a Cl− ion and a sulfonamide group. Furosemide and bumetanide share the sulfamoylbenzoic acid but the Cl− ion in furosemide is replaced with a phenoxy group. Conserved groups in structures are highlighted by the gray background.
