Moreover, non-alcoholic beer, owing to its nutritional value and high content of biological active compounds, is sometimes recommended to patients by oncologists. However, the potential benefits and negatives have to date not been sufficiently evaluated. The present study was designed to examine the effects of four main hop-derived prenylflavonoids on the viability, reactive oxygen species (ROS) formation, activity of caspases, and efficiency of the chemotherapeutics 5-fluorouracil (5-FU), oxaliplatin (OxPt) and irinotecan (IRI) in colorectal cancer cell lines SW480, SW620 and CaCo-2. All the prenylflavonoids exerted substantial antiproliferative effects in all cell lines, with xanthohumol being the most effective (IC50 ranging from 3.6 to 7.3 \u00b5M). Isoxanthohumol increased ROS formation and the activity of caspases-3\/7, but 6-prenylnaringenin and 8-prenylnaringenin exerted antioxidant properties. As 6-prenylnaringenin acted synergistically with IRI, its potential in combination therapy deserves further study. However, other prenylflavonoids acted antagonistically with all chemotherapeutics at least in one cell line. Therefore, consumption of beer during chemotherapy with 5-FU, OxPt and IRI should be avoided, as the prenylflavonoids in beer could decrease the efficacy of the treatment.<\/jats:p>","DOI":"10.3390\/nu11040879","type":"journal-article","created":{"date-parts":[[2019,4,22]],"date-time":"2019-04-22T03:15:53Z","timestamp":1555902953000},"page":"879","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Antiproliferative Effects of Hop-derived Prenylflavonoids and Their Influence on the Efficacy of Oxaliplatine, 5-fluorouracil and Irinotecan in Human ColorectalC Cells"],"prefix":"10.3390","volume":"11","author":[{"given":"Martin","family":"Ambro\u017e","sequence":"first","affiliation":[{"name":"Faculty of Pharmacy in Hradec Kr\u00e1lov\u00e9, Charles University, Heyrovsk\u00e9ho 1203, 500 05 Hradec Kr\u00e1lov\u00e9, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate\u0159ina","family":"Ln\u011bni\u010dkov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Dentistry, Palack\u00fd University, Hn\u011bvot\u00ednsk\u00e1 3, 775 15 Olomouc, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9421-5744","authenticated-orcid":false,"given":"Petra","family":"Matou\u0161kov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy in Hradec Kr\u00e1lov\u00e9, Charles University, Heyrovsk\u00e9ho 1203, 500 05 Hradec Kr\u00e1lov\u00e9, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lenka","family":"Sk\u00e1lov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy in Hradec Kr\u00e1lov\u00e9, Charles University, Heyrovsk\u00e9ho 1203, 500 05 Hradec Kr\u00e1lov\u00e9, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2863-717X","authenticated-orcid":false,"given":"Iva","family":"Bou\u0161ov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy in Hradec Kr\u00e1lov\u00e9, Charles University, Heyrovsk\u00e9ho 1203, 500 05 Hradec Kr\u00e1lov\u00e9, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"E359","DOI":"10.1002\/ijc.29210","article-title":"Cancer incidence and mortality worldwide: Sources, methods and major patterns in GLOBOCAN 2012","volume":"136","author":"Ferlay","year":"2015","journal-title":"Int.
