Summary: This paper presents a study on the synthesis and characterization of a new class of organic corrosion inhibitor called DPCM. The effectiveness of DPCM in inhibiting corrosion on carbon steel was tested and found to increase with temperature and DPCM concentration. The inhibition action of DPCM was achieved through adsorption on the metal surface, forming a protective layer. The molecular configuration of DPCM was also found to affect its inhibition efficiency, as determined by density functional theory (DFT) simulation.

Summary: In this study, eco-friendly functionalized carbon dots (N-CDs) were synthesized using the microwave method. The corrosion inhibition behavior of N-CDs in acidic and saline solutions was systematically investigated, revealing its outstanding inhibitory performance.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
