| Abstract | The aim of the work is to study the mechanisms of the interaction of risperidone with human and bovine serum albumins using the fluorescence quenching technique. Risperidone is an atypical antipsychotic drug used to treat many psychiatric disorders. We selectively excited the fluorescence of tryptophan residues with a 290 nm wavelength light, and observed quenching by titrating human and bovine serum albumin solutions with risperidone. Emission spectra were recorded in the range from 300 to 450 nm for each quencher addition. Stern-Volmer graphs were plotted and quenching constants were estimated. Results showed that the drug quenches the fluorescence of the human serum albumin by the formation of a complex risperidone-albumin. Association constants calculated from Stern-Volmer equation for low concentrations (lower than 1:10 ratio risperidone/albumin) were of 2.56 × 10(5)M(-1), at 25 °C, and 1.43 × 10(5)M(-1), at 37 °C. As the quenching intensity of bovine serum albumin, which contains two tryptophan residues, was found to be higher than that of human serum albumin, which contains only one tryptophan residue. Hence, we suggest that the primary binding site for risperidone in albumin should be located in sub domain IB. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
