ATPase

Bafilomycin A1 prevents maturation of autophagic vacuoles by inhibiting fusion between autophagosomes and lysosomes in rat hepatoma cell line, H-4-II-E cells.

Istaroxime hydrochloride is a positive inotropic agent that mediates its action through inhibition of sodium/potassium adenosine triphosphatase (Na+/K+ ATPase).

Melittin is a Na+/K+ ATPase inhibitor. It inhibits Gs and stimulates Gi activity. It inhibits protein kinase C and cAMP-dependent protein kinases.
