Description
Summary:The leishmanicidal property of piperine intercalated in liposomes and in mannose-coated liposomes was tested in experimental visceral leishmaniasis in hamsters. Mannose-coated liposomal piperine eliminated intracellular amastigotes of Leishmania donovani in splenic macrophages much more efficiently than did the liposomal piperine or free piperine. At a dose equivalent to 6 mg/kg body wt every 4th day for a total of 4 doses in 12 days, the mannose-coated liposomal piperine was found to reduce spleen parasite load to the extent of 90% in comparison to that achieved by liposomal piperine (77%) or free piperine (29%). Histological examination of spleen and liver function tests showed that the toxicity of piperine was reduced when mannosylated liposomal piperine was administered.
