In the current research, a structure-based pharmacophore model was generated to map and screen CMNPD, a comprehensive database of marine natural products. The two compounds (CMNPD30448 (hit1) and CMNPD7060 (hit2)) displayed better LibDock scores than the reference co-crystallized ligand. These compounds demonstrated stable molecular dynamics results conducted for 500 ns with stable root mean square deviation (RMSD) at 0.3 nm, stable radius of gyration (Rg) and root mean square fluctuation (RMSF). On ChEMBL compounds, different PaDEL descriptors and various machine learning (ML) and neural network (NN) methods were used. The results showed that PubChem fingerprints with random forest classification model displayed an accuracy of 0.91 and a receiver operating characteristic area under the curve (ROC-AUC) of 0.96. This model further predicted the retrieved compounds as \u2018active\u2019. The explainable random forest with LIME showed that PubChem fingerprint440 [C(-C)(-O)(=O)], PubChem fingerprint452 [C(-O)(=O)], PubChem fingerprint380 [C(~O)(~O)], PubChem fingerprint566 [O-C-C-N] and PubChem fingerprint712 [C-C(C)-C(C)-C] for hit1 and PubChem fingerprint700 [O-C-C-C-C-C-O-C], PubChem fingerprint380 [C(~O)(~O)], and PubChem fingerprint712 [C-C(C)-C(C)-C] for hit2 have contributed towards plausible inhibitory potential. These findings suggest the two compounds CMNPD30448 and CMNPD7060 might serve as HER2 inhibitors. Further in vitro and in vivo analysis are required before using them.<\/jats:p>","DOI":"10.3390\/ijms27146504","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T10:48:28Z","timestamp":1784717308000},"page":"6504","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Explainable Artificial Intelligence (XAI) and Molecular Modeling Techniques to Discover Putative HER2 Inhibitors"],"prefix":"10.3390","volume":"27","author":[{"given":"Shailima","family":"Rampogu","sequence":"first","affiliation":[{"name":"Cachet Big Data Lab, Hyderabad 500081, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1566-8970","authenticated-orcid":false,"given":"Thananjeyan","family":"Balasubramaniyam","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular Oncology and Innovative Therapies, Military Institute of Medicine\u2014National Research Institute, Szaserow 128, 04-141 Warszawa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheol-Hee","family":"Yoon","sequence":"additional","affiliation":[{"name":"Division of Chronic Viral Diseases, Center for Emerging Virus Research, Korea National Institute of Health, 187 Osongsaengmyeong 2-ro, Cheongju 28159, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongseong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Engineering, Kyungnam University, Changwon 51767, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2772-5127","authenticated-orcid":false,"given":"Jacek Z.","family":"Kubiak","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular Oncology and Innovative Therapies, Military Institute of Medicine\u2014National Research Institute, Szaserow 128, 04-141 Warszawa, Poland"},{"name":"Dynamics and Mechanics of Epithelia Group, Institute of Genetics and Development of Rennes (IGDR), National Centre for Scientific Research (CNRS), Faculty of Medicine, University of Rennes, UMR 6290, 35043 Rennes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keun Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Korea Quantum Computing (KQC), 55 Centumjungang-ro, Haeundae-Gu, Busan 48058, Republic of Korea"},{"name":"Angel i-Drug Design (AiDD), 33-3 Jinyangho-ro 44, Jinju 52650, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1016\/j.ygyno.2024.01.048","article-title":"Human epidermal growth factor receptor-2 (HER2) expression in FIGO3 high-grade endometrial endometrioid carcinoma: Clinicopathologic characteristics and future directions","volume":"185","author":"Abada","year":"2024","journal-title":"Gynecol.
