Abstract
We report a novel antileishmanial formulation of betulin (BET) attached to functionalized carbon nanotubes (f-CNTs). We conjugated betulin, a pentacyclic triterpenoid secondary metabolite, to carboxylic acid chains on f-CNTs to obtain BET attached functionalized carbon nanotubes (f-CNT-Bet). The drug release profile demonstrated a fairly slow release of BET. The in-vitro cytotoxicities of BET, f-CNT and f-CNT-BET on J774A.1 macrophage cell line were 211.05±7.14μg/ml; 24.67±3.11μg/ml and 72.63±6.14μg/ml, respectively. The IC50 of BET and f-CNT-BET against intracellular Leishmania donovani amastigotes were 8.33±0.41μg/ml and 0.69±0.08μg/ml, respectively. The results demonstrate better antileishmanial efficiency of f-CNT-BET formulation than BET alone and with no significant cytotoxicity observed on host cells.Entities:
