Five ligands (10012949, 40242484, 46712145, 15880207, and 33688815) showed high affinity, with 46712145 adopting symmetrical \u03c0\u2013\u03c0 stacking, hydrogen bonds, and alkyl interactions to bypass steric hindrance. Molecular dynamics simulations (100 ns) revealed ligand-induced flexibility, evidenced by elevated RMSD\/Rg values versus the free protein. DCCM analysis highlighted enhanced anti-correlated motions between GHKL motifs and sensor domains in chain B\/C, suggesting stabilization of a non-catalytic conformation to inhibit ATP hydrolysis. Free energy landscape (FEL) analysis showed 46712145 occupying a broad, shallow energy basin, enabling conformational adaptability, contrasting the narrow deep well of the free protein. This study proposes a symmetric ligand design strategy and conformational capture mechanism to block ATPase activity. Compound 46712145 demonstrates stable binding and dynamic regulation, providing a novel lead scaffold for anti-ASFV drug development. These findings establish a structural framework for combating ASFV through targeted ATPase inhibition.<\/jats:p>","DOI":"10.3390\/v17050681","type":"journal-article","created":{"date-parts":[[2025,5,7]],"date-time":"2025-05-07T05:18:20Z","timestamp":1746595100000},"page":"681","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Virtual Screening and Molecular Dynamics Simulation Targeting the ATP Domain of African Swine Fever Virus Type II DNA Topoisomerase"],"prefix":"10.3390","volume":"17","author":[{"given":"Rui","family":"Zhao","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, Xinjiang Agricultural University, Urumqi 830052, China"},{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lezi","family":"Hou","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Henan Agricultural University, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0695-2171","authenticated-orcid":false,"given":"Weldu","family":"Tesfagaber","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linfei","family":"Song","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenjiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhigao","family":"Bu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7161-6214","authenticated-orcid":false,"given":"Dongming","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Xinjiang Agricultural University, Urumqi 830052, China"},{"name":"State Key Laboratory for Animal Disease Control and Prevention, National African Swine Fever Para-Reference Laboratory, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1126\/science.aaz1439","article-title":"Architecture of African Swine Fever Virus and Implications for Viral Assembly","volume":"366","author":"Wang","year":"2019","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"228","DOI":"10.1016\/j.jia.2023.05.021","article-title":"Establishment of an Indirect Immunofluorescence Assay for the Detection of African Swine Fever Virus Antibodies","volume":"23","author":"Wang","year":"2024","journal-title":"J.
