Organelle-targeted BODIPY-conjugated platinum(IV) anticancer prodrugs for overcoming drug resistance.

Platinum-based chemotherapy, despite being a cornerstone of cancer treatment, faces significant challenges due to acquired drug resistance. To address this issue, we have designed three organelle-targeting platinum(IV) prodrugs conjugated with BODIPY fluorophores, enabling spatiotemporal control through green light irradiation. These BODIPY-Pt(IV) conjugates exhibit excellent stability in PBS buffer, demonstrating resilience under physiological conditions.

Antioxidant and Anti-Inflammatory Activities of Methanol Extract of (Viv.) H.S. Irwin & Barneby Through Nrf2/HO-1-Mediated Inhibition of NF-κB Signaling in LPS-Stimulated Mouse Microglial Cells.

Botanical extracts are recognized in traditional medicine for their therapeutic potential and safety standards. Botanical extracts are viable and sustainable alternatives to synthetic drugs, being essential in drug discovery for various diseases. (Viv.

Diverse Structures of Tea Polyphenols from Rougui Wuyi Rock Tea and Their Potential as Inhibitor of 3C-like Protease.

Tea polyphenols, the primary bioactive constituents responsible for the various health benefits of tea, can be categorized into different subgroups according to their structural characteristics. However, the distinctions in antiviral activity among the diverse types of polyphenolic compounds remain unexplored. In the present study, fifty-eight tea polyphenols with varied structures, including eleven undescribed compounds, were isolated from Rougui Wuyi rock tea.

Preparation and Performance Evaluation of High-Temperature Polymer Nano-Plugging Agents for Water-Based Drilling Fluids Systems Applicable to Unconventional Reservoirs.

To address the challenges of micro-fracture development in shale formations, frequent wellbore instability, and the limited plugging capability of water-based drilling fluids in unconventional reservoirs, a nano-plugging agent (NPA) was synthesized using emulsion polymerization. The synthesized NPA was characterized through thermogravimetric analysis (TGA) and transmission electron microscopy (TEM), revealing excellent high-temperature stability and a spherical or sub-spherical morphology, with particle diameters ranging from approximately 20 to 50 nm. The rheological, filtration, and plugging properties of NPA were systematically evaluated, and its sealing mechanism was analyzed.

Inducible regulating homologous recombination enables precise genome editing in Pichia pastoris without perturbing cellular fitness.

The methylotrophic yeast Pichia pastoris (also known as Komagataella pastoris) is an ideal host for producing proteins and natural products. Enhancing homologous recombination (HR) is helpful for improving the precision of genome editing, but results in stress to cellular fitness and is harmful for industrial applications. To overcome these challenges, we developed a tetracycline repressor protein (TetR)/tetO2 inducible system to dynamically regulate the HR-related gene RAD52 in P.
