Organoselenium-based Azomethines as Apoptosis Inducers in Colorectal Carcinoma via P53, BAX, Caspase-3, Caspase-6, and Caspase-9 Modulations.

Background: Organoselenium (OSe) agents and Schiff bases have demonstrated immense potential in the pharmaceutical field due to their broad spectrum of medicinal activities.

Methods: We herein report the antitumor activities of bis diselenide-based Schiff bases (3a-3c) derived from bis(4-aminophenyl)diselenide 2 and organoselenide-based Schiff bases (5a-c) derived from p-(methylselanyl)phenyl amine (4). The antitumor activity was estimated against fifteen cancer cell lines.

In-Vitro Study of the Binding of Atorvastatin with Adenine using Multi-Spectroscopic Approaches.

Atorvastatin-an oral lipid regulating drug is a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), which is the rate determining enzyme for cholesterol synthesis. Adenine is a purine nucleobase that is found in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to generate genetic information. The binding mechanism of atorvastatin and adenine was studied for the first time utilizing various techniques, including UV-visible spectrophotometry, spectrofluorimetry, synchronous fluorescence spectroscopy (SF), Fourier transform infrared (FTIR), fluorescence resonance energy transfer (FRET), and metal ion complexation.

Insights on multi-spectroscopic approaches for estimating the in vitro binding of favipiravir with adenine nucleotide.

Favipiravir (FVP) is an oral antiviral drug approved in 2021 for the treatment of COVID-19. It is a pyrazine derivative that can be integrated into anti-viral RNA products to inhibit viral replication. While, adenine is a purine nucleobase that is found in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to generate genetic information.

UBE2N Is Essential for Maintenance of Skin Homeostasis and Suppression of Inflammation.

UBE2N, a Lys63 ubiquitin-conjugating enzyme, plays critical roles in embryogenesis and immune system development and function. However, its roles in adult epithelial tissue homeostasis and pathogenesis are unclear. We generated conditional mouse models that deleted Ube2n in skin cells in a temporally and spatially controlled manner.

Corrigendum: Co-treatment of chloroquine and trametinib inhibits melanoma cell proliferation and decreases immune cell infiltration.
