In this study, the ligand\u2010based pharmacophore model (HDAA) and the receptor\u2010based pharmacophore model (HHDA) were respectively constructed, which could comprehensively reflect the spatial distribution characteristics of the core groups of IDO\u20101 inhibitors. Subsequently, these pharmacophore models were utilized to guide the design of novel IDO\u20101 inhibitors through a skeleton combination approach. The corresponding molecular structures were synthesized, and evaluated for their biological activities. Notably, compound\n                    <jats:bold>7b<\/jats:bold>\n                    exhibited highly potent IDO\u20101 inhibitory activity, which contributed to the body's immune activation in\u00a0vivo. In summary, the study not only constructed the rational pharmacophore and docking models but also guided the development of novel IDO\u20101 inhibitor skeletons, providing a promising approach to achieving immune activation.\n                  <\/jats:p>","DOI":"10.1111\/cbdd.70207","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T09:44:47Z","timestamp":1765878287000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["From Pharmacophore Models to Lead Compounds: Construction and Activity Evaluation of Novel Indoleamine 2,3\u2010Dioxygenase\u20101 Inhibitors"],"prefix":"10.1111","volume":"106","author":[{"given":"Shiying","family":"Zhang","sequence":"first","affiliation":[{"name":"Institute of BioPharmaceutical Research Liaocheng University  Liaocheng People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anli","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of BioPharmaceutical Research Liaocheng University  Liaocheng People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5983-7436","authenticated-orcid":false,"given":"Bin","family":"Sun","sequence":"additional","affiliation":[{"name":"Institute of BioPharmaceutical Research Liaocheng University  Liaocheng People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,16]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmedchemlett.0c00017"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmolb.2020.604770"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmgm.2021.108107"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmb.2020.10.025"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmech.2018.08.028"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2017.00880"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctrv.2022.102461"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2021.649893"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-0716-0795-4_1"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.61.8.28"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.3390\/jof11070496"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1158\/1078-0432.CCR-22-3911"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cyto.2023.156206"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jmedchem.3c00165"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1063\/5.0088271"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmech.2024.116852"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jmedchem.3c01372"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmgm.2020.107711"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40425-018-0351-9"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.exger.2019.110820"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1002\/eji.202250060"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1021\/jm400049z"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2023.1039244"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1021\/jm9014718"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1080\/13693780802139867"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-57613-8_1"},{"key":"e_1_2_9_28_1","doi-asserted-by":"publisher","DOI":"10.1021\/jm051211n"},{"key":"e_1_2_9_29_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms20184574"},{"key":"e_1_2_9_30_1","doi-asserted-by":"publisher","DOI":"10.3390\/nu12030818"},{"key":"e_1_2_9_31_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13045-022-01325-0"},{"key":"e_1_2_9_32_1","doi-asserted-by":"publisher","DOI":"10.1097\/ICO.0000000000003309"}],"container-title":["Chemical Biology &amp;
