| Description | Introduction: Diabetes mellitus (DM) is a metabolic disorder that results in glucose accumulation in the blood, accompanied by the production of advanced glycation end products (AGEs) through glycation of cellular proteins. These AGEs interfere with insulin signaling and prevent GLUT4 membrane translocation, thereby promoting the accumulation of more glucose in the blood and causing post-diabetic complications.Methods: In this study, we examine the anti-diabetic potential of Lyonia ovalifolia (Wall.) Drude, a well-known ethnomedicinal plant of the Indian Himalayas. Considering its various medicinal properties, we analyzed its ethanolic extract and various solvent fractions for in vitro antiglycation activity and antidiabetic potential, i.e., stimulation of GLUT4 translocation.Result and Discussions: The results showed that the extract and fractions exhibited increased antiglycation activity and an increased level of GLUT4 translocation. Analysis of a further 12 bioactive compounds of ethanolic extract, identified through LC-ESI-QTOF-MS/MS, revealed the presence of three new compounds: leucothol B, rhodoterpenoids A, and leucothol A. Moreover, we performed molecular docking of identified compounds against key proteins of diabetes mellitus: the sirtuin family of NAD (+)-dependent protein deacetylases 6 (SIRT6), aldose reductase (AR), and tyrosine kinase (TK). The results showed that flavonoid luteolin showed the best binding affinity ((−12.3 kcal/mol), followed by eriodictyo... |
| Abstract | Diabetes mellitus (DM) is a metabolic disorder which results in glucose accumulation in the blood accompanied by production of advanced glycation end products(AGEs)through glycation of cellular proteins. These AGEs interfere with insulin signalling and prevent GLUT-4 membrane translocation thereby promoting accumulation of more glucose in the blood and cause post-diabetic complications. In this paper we have examined the anti- diabetic potential of Lyonia ovalifolia (Wall.) Drude, a well-known ethnomedicinal plant of Indian Himalaya. Considering its several medicinal properties, its ethanolic extract and different solvent fractions were analysed for in-vitro anti-glycation activity and antidiabetic potential i.e. stimulation of GLUT-4 translocation. The results showed that extract and fraction showed increased antiglycation activity and an increased level of GLUT-4 translocation. Further 12 bioactive compounds of ethanolic extract identified through LC- ESI-QTOF-MS/MS analysis revealed the presence of three new compound Leucothol B, Rhodoterpenoids A, Leucothol A. Further molecular docking were done of identified compounds against key proteins of diabetes mellitus which includes Sirtuin family of NAD(+)-dependent protein deacetylases 6 (SIRT6), Aldose reductase (AR) and Tyrosine kinase (TK). In results we observed that luteolin revealed the best binding affinity (-12.3 kcal/mol) followed by eriodictyol, astilbin and syringaresinol. The ADMET study showed that luteolin, eriodictyol, astilbin and syringaresinol may be the promising drug candidate without any harmful effect following all the drug-likeness guidelines. Therefore, this study reveals for the first time that L. ovalifolia plays an important role in insulin homeostasis as shown by in vitro and in silico studies. |

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.
