Bacopasaponin C is a triterpenoid saponin originally isolated from B. monniera that has diverse biological activities.1,2,3 It inhibits the ATPase activity of P-glycoprotein (IC50 = 57.83 ?g/ml).4 Bacopasaponin C inhibits scopolamine-induced impairments in spatial memory in the Morris water maze and memory retrieval in the step-down test in mice when administered at a dose of 50 mg/kg.1 It also decreases the time mice spent immobile in the forced swim and tail suspension tests, indicating antidepressant-like activity.2 Bacopasaponin C reduces the spleen parasite load in a hamster model of leishmaniasis when administered as a free compound or in liposomal, niosomal, microencapsulated, or nanocapsulated forms.3
