- Abstract
Objectives: To investigate the applicability, localization, biodistribution and toxicity of self assembled ionically sodium alginate cross-linked AmB loaded glycol chitosan stearate nanoparticles for effective management of visceral leishmaniasis. Methods: Here, we fabricated Amphotericin B (AmB) encapsulated sodium alginate-glycol chitosan stearate nanoparticles (AmB-SA-GCS-NP) using strong electrostatic interaction between oppositely charged polymer and copolymer by ionotropic complexation method. The tagged FAmB-SA-GCS-NP was compared with tagged FAmB for in vitro macrophagic uptake in J774A macrophages and in vivo localization in liver, spleen, lung and kidney tissues. The AmB-SA-GCS-NP and plain AmB were compared for in vitro and in vivo antileishmanial activity, pharmacokinetics, organ distribution and toxicity profiling. Results: The morphology of SA-GCS-NP revealed as nanocrystal (size, 196.3 ± 17.2 nm; PDI, 0.216 ± 0.078; zeta potential, (−) 32.4 ± 5.1 mV) by field emission scanning electron microscopy and high resolution transmission electron microscopy. The macrophage uptake and in vivo tissue localization studies shows tagged FAmB-SA-GCS-NP has significantly higher (~1.7) uptake compared to tagged FAmB. The biodistribution study of AmB-SA-GCS-NP showed more localized distribution towards Leishmania infected organs i.e. spleen and liver while lesser towards kidney. The in vitro (IC, 0.128 ± 0.024 μg AmB/ml) and in vivo (parasite inhibition, 70.21 ± 3.46%) results of AmB-SA-GCS-NP illustrated significantly higher ( P < 0.05) efficacy over plain AmB. The monomeric form of AmB within SA-GCS-NP, observed by UV-visible spectroscopy, favored very less in vitro and in vivo toxicities compared to plain AmB. Conclusion: The molecular organization, toxicity studies, desired localization and biodistribution of cost effective AmB-SA-GCS-NP was found to be highly effective and can be proved as practical delivery platform for better management of leishmaniasis.
