| Abstract | Two new transition metal-substituted Krebs-type sandwich structures of (H2imi)2[(BiW9O33)2{W0.5Ni0.5(H2O)}2{Na4 (H2O)14}{Ni(H2O)3}2]·17.5H2O (3) and (H2imi)2[(BiW9O33)2(WO(OH))2Na4(H2O)13(Zn(H2O)3)2]·12H2O (4) (imi = iminazole) were synthesized using the aqueous solution method, and their structures were identified using elemental analysis, infrared, and ultraviolet spectoscopy, thermogravimetry, and single crystal X-ray diffraction. Two polyoxometalates (POMs) were isomorphic with manganese (Mn2+) and cobalt (Co2+) compounds, (Himi)2[(BiW9O33)2(W(OH)2)2(Mn(H2O)3)2(Na3(H2O)14)]·16H2O (1) and (H2imi)2[(BiW9O33)2(W(OH)2)2(Co(H2O)3)2Na4 (H2O)14]·17H2O (2), which were reported in a previous study. This study continued with the determination of the inhibitory effects of four POMs on human hepatic carcinoma Hep G2 cells. Four compounds were used to compare their effects on the measurement of the sub-G1 (sub-G1 hypodiploid cell population) DNA content, the analysis of nuclear morphology, and the protein expression. The results showed that compound 3 (IC50 = 25.6 ± 1.07 μmol L−1) had a much higher anti-tumor activity than compounds 1 and 4 in Hep G2 cells. Compound 2 had the lowest anti-tumor activities in Hep G2 cells. However, compound 3 showed much higher cytotoxicity than compounds 1, 2 and 4 in QSG-7701 cells. Compound 4 had the lowest cytotoxicity of all of these compounds. These findings indicate the effective relationship between the metal components and structures, and their antitumor activities in Hep G2 cells. |

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.
