The antitumor derivative, C-1748, affects CYP3A4: crosstalk between drug metabolism, CYP3A4 expression and enzymatic activity
PublicationJedną z głównych przeszkód w przewidywaniu wyników terapii u pacjentów z nowotworem jest indywidualny przebieg metabolizmu stosowanych leków wynikający z polimorfizmu genów enzymów metabolizujących, jak również duża zmienność farmakokinetyki leków obserwowana u różnych pacjentów podczas trwania chemioterapii. Z powodu tzw. ''wąskiego okna terapeutycznego'' występującego w przypadku terapii lekami przeciwnowotworowymi, małe zmiany...

Dual-Activity Fluoroquinolone-Transportan 10 Conjugates offer alternative Leukemia therapy during Hematopoietic Cell Transplantation
PublicationHematopoietic cell transplantation (HCT) is often considered a last resort leukemia treatment, fraught with limited success due to microbial infections, a leading cause of mortality in leukemia patients. To address this critical issue, we explored a novel approach by synthesizing antileukemic agents containing antibacterial substances. This innovative strategy involves conjugating fluoroquinolone antibiotics, such as ciprofloxacin...

Heterogeneous distribution of surface electrochemical activity in polycrystalline highly boron-doped diamond electrodes under deep anodic polarization
PublicationThe surface homogeneity of boron-doped diamond electrodes is variable and depends on anodic polarization conditions. The differentiation factor is the gradual and localized change in surface termination. A series of measurements under different polarization conditions was performed in order to investigate the scale of this effect. Nanoscale impedance microscopy (NIM) revealed large variation of surface resistance in individual...

Beyond Antioxidant Activity: Redox Properties of Catechins May Affect Changes in the DNA Methylation Profile—The Example of SRXN1 Gene
PublicationThe role of catechins in the epigenetic regulation of gene expression has been widely studied; however, if and how this phenomenon relates to the redox properties of these polyphenols remains unknown. Our earlier study demonstrated that exposure of the human colon adenocarcinoma HT29 cell line to these antioxidants affects the expression of redox-related genes. In particular, treatment with (−)-epigallocatechin (EGC) downregulated...
