Density functional theory calculations were used to assess the interactions between theophylline and natural nucleobases: adenine (A), guanine (G), cytosine (C), and thymine (T). Different interacting orientations, namely the planar hydrogen\u2010bonded conformations and the vertically stacked geometries between theophylline and nucleobases have been investigated by evaluating the binding energies of the dimeric structures. The strength of hydrogen bonding between theophylline and nucleobases is found to be stronger compared to\n                    <jats:italic>\u03c0<\/jats:italic>\n                    \u2013\n                    <jats:italic>\u03c0<\/jats:italic>\n                    stacking interactions, and hence, it is unlikely that theophylline would invade the DNA duplex and insert between nucleobases. Classical molecular dynamics simulations have been performed to gauge the interactions between theophylline and a DNA double helix. Theophylline is indeed observed to interact with DNA via hydrogen bonding rather than\n                    <jats:italic>\u03c0<\/jats:italic>\n                    \u2013\n                    <jats:italic>\u03c0<\/jats:italic>\n                    stacking, keeping the DNA intact and eliminating any potential damage. Therefore, the adverse drug reactions of theophylline do not originate from the perturbation of DNA, and are of different origins. This research lays a solid groundwork and builds a deep understanding for future investigations aimed at studying interactions between theophylline and biomolecules.\n                  <\/jats:p>","DOI":"10.1002\/cphc.202500523","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T20:48:32Z","timestamp":1763498912000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Molecular Insights into the Binding of Theophylline with DNA: An \u201c\n                    <i>In\u2009Silico<\/i>\n                    \u201d Approach"],"prefix":"10.1002","volume":"27","author":[{"given":"Anik","family":"Ghosh","sequence":"first","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prasenjit","family":"Sen","sequence":"additional","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rimpa","family":"Kundu","sequence":"additional","affiliation":[{"name":"IISER Kolkata Mohanpur Campus  PO: BCKV Campus Main Office Mohanpur Nadia 741252 West Bengal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammed Mubarak","family":"Kadakkadan Palliyalil","sequence":"additional","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sruti","family":"Shaw","sequence":"additional","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2505-6732","authenticated-orcid":false,"given":"Titas Kumar","family":"Mukhopadhyay","sequence":"additional","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7443-5419","authenticated-orcid":false,"given":"Subrata","family":"Mahanta","sequence":"additional","affiliation":[{"name":"Department of Chemistry National Institute of Technology Jamshedpur  Adityapur Jamshedpur Jharkhand 831014 India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,11,18]]},"reference":[{"key":"e_1_2_10_2_1","first-page":"725","volume":"3","author":"Barnes P.
