Abstract
Biocompatible and biodegradable sustained drug delivery system has been constructed from reaction between norfloxacin and cyclodextrin through secondary amine of piperazine ring and hydroxyl group of the carbohydrate. Covalent bond polymeric structure is designed by the help of chloroacetyl chloride, target dendrimer formed by removing two hydrochloride molecules. The development of cyclodextrin core drug delivery system with twenty one norfloxacin surface moiety has been synthesized by only two steps. The synthesized polymeric structure was thoroughly studied by NMR, FT-IR, MALDI and UV- spectrometry. Sustained release assessment of synthetic polymer studied through different buffer solution by UV spectrometry and norfloxacin releases rate of synthetic polymer was controlled by the concentration and the experimental medium. The microbial assessments through kinetic studies by using Escherichia coli also reveal that the norfloxacin released possesses potential antimicrobial activity. Antibacterial activity of synthesized drug delivery system has been investigated with gram-negative and gram-positive species like Escherichia coli (mtcc 443), bacillus subtilis (mtcc 2063), pseudomonas (mtcc 741), staphylococcus (mtcc 737) and proteus mirabilis (mtcc 425). The hydrophobic and hydrophilic balance and the repeat drug unit of this synthesized system are responsible for effective antibacterial activity. The minimum inhibitor concentration values of this system are very small to 100 µg/mL-1, synthesized compound shown five times improved activity against organism on comparism with standard drug. The in-vitro release of norfloxacin from obtained dendrimer was investigated.
