The in vitro results showed that the CP derivative significantly suppressed the growth of HCT-116 and LOX IMVI cells, with IC50 values of 5.0 \u03bcM and 1.3 \u03bcM, respectively, outperforming Staurosporine, which had IC50 values of 8.4 \u03bcM and 1.6 \u03bcM, respectively. Flow cytometry analysis revealed that the new CP derivative triggered apoptosis and cell cycle arrest at the G2\/M phase, associated with the up-regulation of pro-apoptotic genes (Bax and Caspase 9) and downregulation of the anti-apoptotic gene (Bcl-2). Further investigations showed that the CP derivative inhibited Topo I and II enzymes, as expected molecular targets; docking studies further supported its dual inhibitory action on Topo I and II. These findings suggest that the ciprofloxacin-chalcone hybrid could be a promising lead compound for developing new anticancer therapy.<\/jats:p>","DOI":"10.3390\/molecules29225382","type":"journal-article","created":{"date-parts":[[2024,11,15]],"date-time":"2024-11-15T04:47:17Z","timestamp":1731646037000},"page":"5382","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Unveiling the Anticancer Potential of a New Ciprofloxacin-Chalcone Hybrid as an Inhibitor of Topoisomerases I &amp; II and Apoptotic Inducer"],"prefix":"10.3390","volume":"29","author":[{"given":"Doaa Mohamed Elroby","family":"Ali","sequence":"first","affiliation":[{"name":"Department of Biochemistry, Faculty of Pharmacy, Sohag University, Sohag 82524, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hossameldin A.","family":"Aziz","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, New Valley University, New Valley 72511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4845-3191","authenticated-orcid":false,"given":"Stefan","family":"Br\u00e4se","sequence":"additional","affiliation":[{"name":"Institute of Biological and Chemical Systems\u2014Functional Molecular Systems (IBCS-FMS), Karlsruhe Institute of Technology (KIT), Kaiserstrasse 12, 76131 Karlsruhe, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Areej","family":"Al Bahir","sequence":"additional","affiliation":[{"name":"Chemistry Department, Faculty of Science, King Khalid University, Abha 64734, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2000-2620","authenticated-orcid":false,"given":"Abdullah","family":"Alkhammash","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, College of Pharmacy, Shaqra University, Shaqra 11961, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gamal El-Din A.","family":"Abuo-Rahma","sequence":"additional","affiliation":[{"name":"Department of Medicinal Chemistry, Faculty of Pharmacy, Minia University, Minia 61519, Egypt"},{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Deraya University, New Minia City 61768, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali M.","family":"Elshamsy","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Deraya University, New Minia City 61768, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8649-7534","authenticated-orcid":false,"given":"Hamada","family":"Hashem","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Sohag University, Sohag 82524, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walid M.","family":"Abdelmagid","sequence":"additional","affiliation":[{"name":"Medicinal Chemistry and Drug Discovery Research Centre, Swenam College, 210-6125 Sussex Avenue, Burnaby, BC V5H 4G1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Abdel-Rahman, I.M., Mustafa, M., Mohamed, S.A., Yahia, R., Abdel-Aziz, M., Abuo-Rahma, G.E.-D.A., and Hayallah, A.M.
