AI Article Synopsis
- * Platinum drugs, while effective, are known for their serious side effects and limited effectiveness, prompting the exploration of alternative treatments.
- * New Cu(II) terpyridine complexes have shown potent anti-cancer activity in low concentrations, inducing cell death through mechanisms involving reactive oxygen species, making them promising candidates for future drug development.
Article Abstract
Cancer is considered as the biggest medicinal challenge worldwide. During a typical treatment, the tumorous tissue is removed in a surgical procedure and the patient further treated by chemotherapy. One of the most frequently applied drugs are platinum complexes. Despite their clinical success, these compounds are associated with severe side effects and low therapeutic efficiency. To overcome these limitations, herein, the synthesis and biological evaluation of Cu(II) terpyridine complexes as chemotherapeutic drug candidates is suggested. The compounds were found to be highly cytotoxic in the nanomolar range against various cancer cell lines. Mechanistic insights revealed that the compounds primarily accumulated in the cytoplasm and generated reactive oxygen species in this organelle, triggering cell death by apoptosis. Based on their high therapeutic effect, these metal complexes could serve as a starting point for further drug development.

Chlorinated coumarins, which are as cytotoxic as highly toxic halobenzoquinones toward CHO-K1 cells, have recently been identified as disinfection byproducts in drinking water disinfection processes. Therefore, detecting coumarins in water samples collected at various stages from drinking water treatment plants helps assess the formation of chlorinated coumarins in drinking water. Hence, a simple, rapid, accurate, and sensitive method for quantifying coumarins in water samples is required.

Unlabelled: Thermal spray, in general, is a process that involves forcing a melted substance, such as metal or ceramic in the form of wire or powder, onto the surface of a targeted object to enhance its desired surface properties. In this paper, the melted substance is metal wire generated by an electric arc and forcibly coated on a rotary iron substrate using compressed air. This thermal process is referred to as double-wire arc thermal spray.

Microbes in general, actinomycetes in particular, produce a wide range of antibiotics with various biological activities such as anticancer, antimicrobial, anti-inflammatory, antituberculosis and enzyme inhibition. Actinomycetes are filamentous gram-positive bacteria found in both terrestrial and marine environments. Currently, antibiotics such as Rifamycin, Tetracycline, Kanamycin, Neomycin, Streptomycin and Clavulanic acid derived from actinobacteria are highly useful in the medical field.

The redox imbalance, caused by depletion or generation of reactive oxygen species (ROS), is a key mechanism by which metal complexes exert anticancer effects. Carbidopa has shown the ability to inhibit the MDA-MB-231 cell line, a highly aggressive triple-negative human breast adenocarcinoma, by inducing reductive stress. The metal complex of carbidopa with zinc (ZnCarbi) was designed to modify carbidopa's structure and exhibited increased cytotoxicity against MDA-MB-231 cells.

Background: Bile salts enriched nanovesicles (bilosomes) have been attention worthy in the past few years due to their distinctive effect on the enhancement of drug delivery through various physiological administration routes. Oral delivery of multifunctioning phytochemical curcumin has faced a lot of difficulties due to its scarce solubility and poor oral bioavailability.
Objective: The current investigation aimed to develop curcumin loaded bilosomes for improvement of oral curcumin bioavailability with maximum efficiency and safety.
