Various strategies to overcome the MDR phenomenon have been developed, and one of the most attractive research directions is focused on the inhibition of MDR transporters, membrane proteins that extrude cytotoxic drugs from living cells. Here, we report the results of our studies on a series newly synthesized of 5-arylidenerhodanines and their ability to inhibit the ABCB1 efflux pump in mouse T-lymphoma cancer cells. In the series, compounds possessing a triphenylamine moiety and the carboxyl group in their structure were of particular interest. These amphiphilic compounds showed over 17-fold stronger efflux pump inhibitory effects than verapamil. The cytotoxic and antiproliferative effects of target rhodanines on T-lymphoma cells were also investigated. A putative binding mode for 11, one of the most potent P-gp inhibitors tested here, was predicted by molecular docking studies and discussed with regard to the binding mode of verapamil.<\/jats:p>","DOI":"10.3390\/ijms231810812","type":"journal-article","created":{"date-parts":[[2022,9,18]],"date-time":"2022-09-18T23:39:22Z","timestamp":1663544362000},"page":"10812","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["5-Arylidenerhodanines as P-gp Modulators: An Interesting Effect of the Carboxyl Group on ABCB1 Function in Multidrug-Resistant Cancer Cells"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1946-9370","authenticated-orcid":false,"given":"Ewa","family":"\u017bes\u0142awska","sequence":"first","affiliation":[{"name":"Institute of Biology, Pedagogical University of Krakow, Podchor\u0105\u017cych 2, 30-084 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8336-4288","authenticated-orcid":false,"given":"Waldemar","family":"Tejchman","sequence":"additional","affiliation":[{"name":"Institute of Biology, Pedagogical University of Krakow, Podchor\u0105\u017cych 2, 30-084 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annam\u00e1ria","family":"Kincses","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Albert Szent-Gy\u00f6rgyi Medical School, University of Szeged, H-6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8085-0950","authenticated-orcid":false,"given":"Gabriella","family":"Spengler","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Albert Szent-Gy\u00f6rgyi Medical School, University of Szeged, H-6720 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Nitek","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grzegorz","family":"\u017buchowski","sequence":"additional","affiliation":[{"name":"Chair of Organic Chemistry, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3025-7002","authenticated-orcid":false,"given":"Ewa","family":"Szyma\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Technology and Biotechnology of Drugs, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"861","DOI":"10.2174\/138945006777709593","article-title":"Pharmacological strategies for overcoming multidrug resistance","volume":"7","author":"Nobili","year":"2006","journal-title":"Curr.
