The developed approach allowed for the production of a series of new azaphenothiazine derivatives with the 1,2,3-triazole system in different positions of the benzene ring. In practice, the methodology consists of the reaction of triazole aniline derivatives with thioquinanthrenediinium bis-chloride. The structure of the products was determined by 1H-NMR, 13C-NMR spectroscopy, and HR-MS spectrometry, respectively. Moreover, the spatial structure of the molecule and the arrangement of molecules in the crystal (unit cell) were determined by X-ray crystallography. The anticancer activity profiles of the synthesized compounds were tested in vitro against human cancer cells of the A549, SNB-19, and T47D lines and the normal NHDF cell line. Additional tests of antibacterial activity against methicillin-sensitive and methicillin-resistant staphylococci, vancomycin-sensitive and vancomycin-resistant enterococci, and two mycobacterial strains were also performed. In fact, the dependence of anticancer and antibacterial activity on the substituent type and its position in the quinobenzothiazinium system was observed. Furthermore, the distance-guided property evaluation was performed using principal component analysis (PCA) and hierarchical clustering analysis (HCA) on the pool of the calculated descriptors. Finally, the theoretically approximated partition coefficients (clogP) were (inter-)correlated with each other and cross-compared with the empirically specified logPTLC parameters.<\/jats:p>","DOI":"10.3390\/ijms241713250","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T01:56:57Z","timestamp":1693187817000},"page":"13250","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Towards Anticancer and Antibacterial Agents: Design and Synthesis of 1,2,3-Triazol-quinobenzothiazine Derivatives"],"prefix":"10.3390","volume":"24","author":[{"given":"Ewa","family":"Kisiel-Nawrot","sequence":"first","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Pharmaceutical Sciences in Sosnowiec, Medical University of Silesia, Jagiello\u0144ska 4, 41-200 Sosnowiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominika","family":"Pindjakova","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Natural Sciences, Comenius University, Ilkovicova 6, 842 15 Bratislava, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malgorzata","family":"Latocha","sequence":"additional","affiliation":[{"name":"Department of Cell Biology, Faculty of Pharmaceutical Sciences in Sosnowiec, Medical University of Silesia, Jedno\u015bci 9, 41-200 Sosnowiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9842-1289","authenticated-orcid":false,"given":"Andrzej","family":"Bak","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, University of Silesia, Szkolna 9, 40-006 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Violetta","family":"Kozik","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, University of Silesia, Szkolna 9, 40-006 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kinga","family":"Suwinska","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Natural Sciences, Cardinal Stefan Wyszy\u0144ski University, K.
