Preparation of alginate-chitosan-cyclodextrin micro- and nanoparticles loaded with anti-tuberculosis compounds.
This paper describes the synthesis and application of alginate-chitosan-cyclodextrin micro- and nanoparticulate systems loaded with isoniazid (INH) and isoconazole nitrate (ISN) as antimycobacterial compounds. Preparation and morphology of the obtained particles, as well as antimycobacterial activity data of the obtained systems are presented. Docking of isoconazole into the active site of enoyl-acyl carrier protein reductase (InhA) ofMycobacetrium tuberculosiswas carried out in order to predict the binding affinity and non-covalent interactions stabilizing the InhA-isoconazole complex. To assess these interactions, frontier molecular orbital calculations were performed for the active site of InhA and isoconazole obtained from docking. Isoconazole was predicted to be an active inhibitor of InhA with the analysis of the molecular docking and electron density distribution. It has been detected that alginate-chitosan-cyclodextrin microparticulate systems loaded with INH and ISN are as effective as pure INH applied in higher dosages.
