The increased level of cytochrome P450 isoenzyme CYP3A4 affects the cellular response in CHO cells upon antitumor imidazoacridinone C-1311 treatment
PublicationPochodna C-1311 to potencjalny związek przeciwnowotworowy, który dotarł do II fazy badań klinicznych. Związek ten ulega metabolicznej transformacji pod wpływem szczurzych i ludzkich białek mikrosomalnych. Wykazano, że białka cytochromu P450 odpowiadają za przemiany metaboliczne C-1311 jedynie w niewielkim stopniu. Z drugiej strony wykazano, że pochodna C-1311 jest inhibitorem białek cytochromu P450, zwłaszcza izoenzymu CYP1A2...

Hydroxyl and sulfate radical-based degradation of ciprofloxacin using UV-C and/or Fe2+-catalyzed peroxymonosulfate: Effects of process parameters and toxicity evaluation
PublicationCiprofloxacin (CIP) is a valuable antibiotic and discharged in huge quantities in aquatic environment. Different •OH and SO4•−-based advanced oxidation technologies (AOTs), e.g., Fe2+/PMS, UV-C/PMS, and UV-C/Fe2+/PMS are developed for treatment of CIP. The removal of CIP by Fe2+/PMS, UV-C/PMS and UV-C/Fe2+/PMS was 63, 77, and 87 %, respectively, under identical conditions which showed better performance of UV-C/Fe2+/PMS. The UV-C/Fe2+/PMS...

Cellular Effects of Selected Unsymmetrical Bisacridines on the Multicellular Tumor Spheroids of HCT116 Colon and A549 Lung Cancer Cells in Comparison to Monolayer Cultures
PublicationMulticellular tumor spheroids are a good tool for testing new anticancer drugs, including those that may target cancer stem cells (CSCs), which are responsible for cancer progression, metastasis, and recurrence. Therefore, we applied this model in our studies of highly active antitumor unsymmetrical bisacridines (UAs). We investigated the cellular response induced by UAs in 2D and 3D cultures of HCT116 colon and A549 lung cancer...
