| Abstract | A series of novel azomethine precursors were derivatized by the condensation of 4H-1,2,4-triazole-4-amine with salicylaldehyde (HL $^{1}$) (saltrz), 2,3-dihydroxybenzaldehyde (HL $^{2}$) (dhtrz), 2-hydroxy-1-naphthaldehyde (HL $^{3}$) (ndtrz) and 5-chloro-2-hydroxybenzaldehyde (HL $^{4}$) (cltrz). Subsequently, oxovanadium(IV) complexes of the type [VO(saltrz)$_{2}$] (1), [VO(dhtrz)$_{2}$] (2), [VO(ndtrz)$_{2}$] (3), and [VO(cltrz)$_{2}$] (4) were synthesized by the reactions of vanadyl(V) isopropoxide [VO(OCHMe$_{2}$)$_{3}$] with the ligands HL $^{1}$–HL $^{4}$. The synthesized compounds were characterized by the melting point method, elemental analysis, FT-IR and 1H and $^{13}$C NMR spectroscopies, the molar susceptibility and conductivity methods, and by the thermogravimetry. Ligands HL $^{3}$ and HL $^{4}$ were also characterized by single crystal analysis. The binding modes of SS-DNA with the compounds were confirmed by the hypochromism and red/blue shift of the UV-Vis spectra. The negative DG values of the compound-DNA adducts show that the binding is a spontaneous process. The complexes were found to be persuasive inhibitors of enzyme alkaline phosphatase (ALP). The in vitro screening of the antimicrobial activities of the synthesized compounds revealed significantly enhanced activities of oxovanadium(IV) complexes as compared to their respective ligands. The promising results were obtained in studying the insulin mimetic of the synthesized compounds. |

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.
