Gitoxin (60 min after a 10 min pre-incubation) exerts a biphasic inhibitory effect on erythrocyte membrane Na+/K+-ATPase, with stronger inhibitory potency against the high-affinity subtype (IC50 = 2.98 × 10-7 M), and it exhibits positive cooperative binding with this enzyme[1].
Gitoxin (60 min after 10 min pre-incubation) exerts biphasic inhibition on Na+/K+-ATPase from porcine cerebral cortex, with stronger inhibitory potency against the high-affinity isoform (IC50 = 1.18 × 10-6 M), and it exhibits positive cooperative binding with this enzyme[1].
