Various approaches were used to determine their lipophilicity and predict pharmacokinetic properties. The lipophilicity parameters log kw were determined using isocratic column chromatography and various stationary phases. Based on the standard curve and retention measurements by using an octadecyl column, the log D7.4 distribution coefficient was determined. A weak correlation was found between the experimentally determined log kw parameters and the in silico calculated log P descriptors. It was shown that the compounds partially exist in an ionized anionic form at physiological pH. The determined log D7.4 parameter indicates that most of them have lipophilic character at the level recommended for potential drugs.<\/jats:p>","DOI":"10.3390\/molecules30193913","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T12:59:46Z","timestamp":1759150786000},"page":"3913","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["In Silico and RP HPLC Studies of Biologically Active 1,3,4-Thiadiazol-2-yl)-benzene-1,3-diols"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8226-1922","authenticated-orcid":false,"given":"Marek","family":"Studzi\u0144ski","sequence":"first","affiliation":[{"name":"Department of Physical Chemistry, Faculty of Chemistry, Institute of Chemical Sciences, Maria Curie-Sk\u0142odowska University, 20-031 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Bara\u0144ska","sequence":"additional","affiliation":[{"name":"Independent Radiopharmacy Unit, Medical University of Lublin, Chodzki 4a, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beata","family":"Paw","sequence":"additional","affiliation":[{"name":"Department of Medicinal Chemistry, Medical University of Lublin, Jaczewskiego St. 4, 20-090 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bogus\u0142aw","family":"Senczyna","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Life Sciences in Lublin, Akademicka 15, 20-950 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2864-2211","authenticated-orcid":false,"given":"Tadeusz","family":"Paszko","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Life Sciences in Lublin, Akademicka 15, 20-950 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0363-4450","authenticated-orcid":false,"given":"Joanna","family":"Matysiak","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Life Sciences in Lublin, Akademicka 15, 20-950 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"96","DOI":"10.1016\/j.ejps.2014.05.017","article-title":"Drug Delivery: A Process Governed by Species-Specific Lipophilicities","volume":"62","author":"Mazak","year":"2014","journal-title":"Eur.
