| Abstract | Two diketone based oxovanadium complexes, viz., bis(4,4,4-trifluoro-1-phenylbutane-1,3-dionato)oxovanadium(IV) (1) and bis(1,1,1-trifluoropentane-2,4-dionato)oxovanadium(IV) (2), have been synthesized and characterized by spectroscopic and analytical techniques. The DNA binding and the cleaving ability of the complexes is assessed by UV-vis spectroscopy, fluorescence spectroscopy, viscometry and gel electrophoretic studies. The DNA binding constant values (Kb) are found to be 1.95 ± 0.16 × 10(3)M(-1) for complex 1 and 1.064 ± 0.17 × 10(3)M(-1) for complex 2, respectively. Based on the results of the spectral and viscosity studies, it is observed that the complexes, interestingly, have preferred minor groove binding with DNA. Further, the concentration-dependent oxidative cleavage pattern of pBR322 in the presence of the activating reagent, hydrogen peroxide, has also been discussed. In addition, the complexes have shown moderate cytotoxic activity by inducing apoptosis against the cervical cancer cell line, HeLa. The results of in silico analysis and logP predictions are found to be in good agreement with the experimental observations. Thus, synthesized oxovanadium complexes have displayed promising DNA binding behavior and DNA cleavage activity with moderately cytotoxic nature. |

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.
