| Abstract | The formation of host–guest inclusion complex of levofloxacin with β-cyclodextrin (β-CD) was studied by fluorescence spectroscopy in buffer solution (pH 7.4) at 298 K. The experimental results confirmed the existence of 1:1 inclusion complex of levofloxacin with β-CD. The association constant of the β-CD inclusion complex was obtained from the Benesi–Hildebrand equation. The formation of the inclusion complex was confirmed by the IR and 1H NMR technique. The complex formation equilibria between Gd(III) ion and levofloxacin were investigated in aqueous solutions without and in the presence of β-cyclodextrin. The stoichiometry and stability constants of the formed complexes are reported, and the concentration distribution of the various complex species has been evaluated as a function of pH. The effect of β-cyclodextrin on dissociation constants, K a, of levofloxacin and stability constants of gadolinium(III)– levofloxacin complexes, β p,q,r, were examined. Furthermore, effect of levofloxacin on the speciation and distribution Gd(III) in human blood plasma was evaluated by computer simulation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
