| Abstract | In recent decades, viral outbreaks have significantly threatened global health, with herpes simplex virus type 2 (HSV-2) being one of the most prevalent infections. This study evaluated novel spiropyrimidine derivatives as potential antiviral agents against HSV-2, building on previous research that examined spirocyclic thiopyrimidinone derivatives against human coronavirus 229E (hCoV-229E). Among the eleven synthesized compounds, spiropyrimidinone derivative 3 demonstrated promising antiviral activity, with a selectivity index of 11.2. The drug mechanism of infection studies indicated that compound 3 primarily inhibits HSV-2 at the viral adsorption stage, achieving approximately 83% inhibition and reducing viral multiplication by 34%. Its efficacy is linked to its diketone moiety, which is known for its ability to enhance antiviral effects. Furthermore, the effect of compound 3 on viral inhibition is reflected in the level of caspase-3 protein expression, revealing that the apoptotic pathway is modulated. Docking studies revealed multiple interactions with herpes virus entry mediator (HVEM), indicating its potential as an entry inhibitor. These findings confirm that compound 3 could be a potential candidate for further development in HSV-2 antiviral therapy. Graphical Abstract |

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.
