Electrochemical simulation of metabolism for antitumor-active imidazoacridinone C-1311 and in silico prediction of drug metabolic reactions
PublikacjaThe metabolism of antitumor-active 5-diethylaminoethylamino-8-hydroxyimidazoacridinone (C-1311) has been investigated widely over the last decade but some aspects of molecular mechanisms of its metabolic transformation are still not explained. In the current work, we have reported a direct and rapid analytical tool for better prediction of C-1311 metabolism which is based on electrochemistry (EC) coupled on-line with electrospray...

Inkjet Printing of Lanthanide–Organic Frameworks for Anti-Counterfeiting Applications
PublikacjaPhotoluminescent lanthanide−organic frameworks (Ln-MOFs) were printed onto plastic and paper foils with a conventional inkjet printer. Ln-MOF inks were used to reproduce color images that can only be observed under UV light irradiation. This approach opens a new window for exploring Ln-MOF materials in technological applications, such as optical devices (e.g., lab-on-a-chip), as proof of authenticity for official documents.

Morphological and cellular alternations of HepG2 cells overexpressing CYP3A4 after treatment with antitumor imidazoacridinone derivative C-1311
PublikacjaW pracy badano odpowiedź biologiczną komórek nowotworu wątroby HepG2 z nadekspresją izoenzymu CYP3A4 pod wpływem pochodnej imidazoakrydonu C-1311. Wyniki porównywano z odpowiedzią komórek HepG2 z tzw. wektorem zerowym.Izoeznym CYP3A4 jest jednym z izoenzymów cytochromu P450 odpowiedzialnych za przemiany metaboliczne pochodnej C-1311. Wykazano, że pochodna C-1311 indukuje w obu liniach komórkowych blok w fazie G2/M cyklu komórkowego,...

Imidazoacridinone antitumor agent, c-1311, as a selective mechanism-based inactivator of human recombinant cytochrome P450 1A2
PublikacjaPrzedmiotem badań była przeciwnowotworowa pochodna imidazoakrydonu, C-1311, która pod nazwą Symadex R, znajduje się aktualnie w II fazie badań klinicznych. Wcześniejsze wyniki pozwoliły stwierdzić, że związek ten jest selektywnym inhibitorem niektórych enzymów cytochromowych. Podjęto zatem próbę wyjaśnienia mechanizmu inhibicji izoenzymów cytochromu P450 przez C-1311. Wykazano, że utrata aktywności katalitycznej obu izoenzymów...

The imidazoacridinone C-1311 induces p53-dependent senescence or p53-independent apoptosis and sensitizes cancer cells to radiation
PublikacjaC-1311 is a small molecule, which has shown promise in a number of preclinical and clinical studies. However, the biological response to C-1311 exposure is complicated and has been reported to involve a number of cell fates. Here, we investigated the molecular signaling which determines the response to C-1311 in both cancer and non-cancer cell lines. For the first time we demonstrate that the tumor suppressor, p53 plays a key role...

Influence of the electrosynthesis conditions on the spontaneous release of anti-inflammatory salicylate during degradation of polypyrrole coated iron for biodegradable cardiovascular stent
PublikacjaIn this work, the spontaneous release of anti-inflammatory salicylate from polypyrrole (PPy) coated iron has been studied during degradation of the material in phosphate buffer saline at 37 C. The sodium salicylate was incorporated into PPy in a one-step electropolymerization process. The influence of the synthesis conditions such as sodium salicylate concentration, pyrrole concentration and deposition charge on drug release profile...

Imidazoacridinone antitumor agent C-1311 as a selective mechanism- based inactivator of human cytochrome P450 1A2 and 3A4 isoenzymes.
Publikacja5-Diethylaminoethylamino-8-hydroxyimidazoacridinone (C-1311), a promising antitumor agent that is also active against autoimmune diseases, was determined to be a selective inhibitor of the cytochrome P450 (CYP) 1A2 and 3A4 isoenzymes. Therefore, C-1311 might modulate the effectiveness of other drugs used in multidrug therapy. The present work aimed to identify the mechanism of the observed C-1311-mediated inactivation of CYP1A2...

Effect Of Resveratrol And Quercetin On Telomerase Regulation In Cancer Cells And Their Anti-Cancer Potential
PublikacjaTelomeres and telomerase are nowadays one on targets for anticancer therapy. Telomerase is expressed in ~90% of human cancer cell lines and tumor specimens, whereas its enzymatic activity is not detectable in most human somatic cells. Was found that some dietary compounds can modulate telomerase activity in cancer cells. This review summarizes the current knowledge about the effects of resveratrol and quercetin on telomerase regulation...

Role of Human UDP-Glucuronosyltransferases in the Biotransformation of the Triazoloacridinone and Imidazoacridinone Antitumor Agents C-1305 and C-1311 : Highly Selective Substrates for UGT1A10
Publikacja5-Diethylaminoethylamino-8-hydroxyimidazoacridinone, C-1311 (NSC-645809), is an antitumor agent shown to be effective against breast cancer in phase II clinical trials. A similar compound, 5-dimethylaminopropylamino-8-hydroxytriazoloacridinone, C-1305, shows high activity against experimental tumors and is expected to have even more beneficial pharmacological properties than C-1311. Previously published studies showed that these...
