| Abstract | Hepatocellular carcinoma is the fifth most common cancer responsible for more than 600,000 deaths per year. It is a typical vascular tumor which at earlier stages does not exhibit remarkable development of tumor; however, at advance stages, it is richly supplied by blood vessels and damages hepatocyte, the main functional cell types in the liver. Currently, surgery and chemotherapy are the main treatment strategies. However, the chemotherapeutic agents are usually unable to discriminate between normal and cancerous cells, and hence adverse effects of drug toxicities have become the major concerns in chemotherapy. Thus, inducing caspase dependent cytotoxicity in cancer cells via apoptosis has become one of the interesting and effective strategies for fighting this disease. The current study is an effort to further explore this area of research. Mn(II), Cu(II), and Zn(II) Schiff base complexes were prepared by condensation of 2-hydroxy-1-naphthaldehyde with either 4-nitrobenzene-1,2-diamine or 4-methylbenzene-1,2-diamine and characterized by Spectroscopic (FT-IR, UV–Vis, NMR, and MS) and microanalysis. The ligands, in comparison to their metal complexes, were evaluated for their anticancer and proapoptotic properties in human hepatocarcinoma (HepG2) cells. Results showed that the complexes are more potent proapoptotic agents than the parent ligands. All the tested compounds showed dose-dependent antiproliferative activity comparable with 5-fluorouracil (IC50 = 4.6 μg/mL). All the synthesized Schiff base ligands and respective metal complexes showed potential anticancer activity. Out of them, some compounds showed IC50 value as low as 1.24–3.56 μg/mL. Compounds 3 and 7 inhibited HepG2 cell proliferation by inducing apoptosis via activation of caspase cascade. |

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.
