| Abstract | We previously reported synthesis of novel arene ruthenium (Ru) complexes and evaluated their antitumor activity in murine lymphoma (DL) cells. In this present study we further investigated the mechanism of action of two ruthenium complexes [complex 1 (η6-arene)RuCl(2-pcdpm)] and complex 2 (η6-arene)RuCl(4-mtdpm)] in cervical cancer cell line (HeLa). Our studies demonstrate that anticancer property of these two complexes was due to induction of apoptosis through p53 mediated pathway as well as arrest of cells in G2/M phase of cell cycle. It is worth to note that the complexes did not cause any substantial cytotoxic effect on normal cells. Further in comprehensive studies, apoptosis inducing property of both complexes were established in accordance with array of morphological changes ranging from membrane blebbing to formation of apoptotic bodies and followed by DNA fragmentation assay. Furthermore, Flow cytometry by Annexin V/PI staining delineate that complex 1 and 2 have strident impact to induce apoptosis in HeLa cells. The complex 1 and 2 treated cells show increased level of intracellular ROS generation which was preceded by p53 activation. Apoptosis induced by 1 and 2 was preceded by mitochondrial aggregations which were monitored by mitotracker. In addition flow cytometry analysis showed that both complexes also effectively arrest cells at G /M phase of cell cycle. Western blot, RT-PCR as well as Real Time analysis were used to further confirm that the complexes induced apoptosis in p53 dependent pathway. Thus, our promising results can contribute to the rational design of novel potential anticancer agents. |

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.
