Mechanism of Action

Targets/IC₅₀/Ki	ergosterol
In vitro	Amphotericin B administration is limited by infusion-related toxicity, including fever and chills, an effect postulated to result from proinflammatory cytokine production by innate immune cells. This compound induces signal transduction and inflammatory cytokine release from cells expressing TLR2 and CD14. It interacts with cholesterol, the major sterol of mammal membranes, thus limiting the usefulness of this chemical due to its relatively high toxicity. This drug is dispersed as a pre-micellar or as a highly aggregated state in the subphase. It only kills unicellular Leishmania promastigotes (LPs) when aqueous pores permeable to small cations and anions are formed. This compound (0.1 mM) induces a polarization potential, indicating K+ leakage in KCl-loaded liposomes suspended in an iso-osmotic sucrose solution. It (0.05 mM) exhibits a nearly total collapse of the negative membrane potential, indicating Na+ entry into the cells.
In vivo	Amphotericin B results in prolonging the incubation time and decreasing PrPSc accumulation in the hamster scrapie model. This compound markedly reduces PrPSc levels in mice with transmissible subacute spongiform encephalopathies (TSSE). It exerts a direct effect on Plasmodium falciparum and influences eryptosis of infected erythrocytes, parasitemia and hostsurvival in murine malaria. This chemical tends to delay the increase of parasitemia and significantly delays host death plasmodium berghei-infected mice.
