Sensitive Detection of Sulfur Mustard Poisoning via N-Salicylaldehyde Naphthyl Thiourea Probe and Investigation into Detoxification Scavengers.

Sulfur mustard (SM), a blister agent and toxic chemical warfare compound, leads to injuries in the skin, eyes, and lungs, with early diagnosis being difficult because of its incubation period. Developing scavengers for sulfur mustard (SM) and its simulant, 2-chloroethylsulfide (CEES), is essential due to the severe and long-lasting toxic effects these compounds have on the human body. Existing scavengers like cysteine, sodium hydrosulfide (NaHS), and sodium thiosulfate cannot cross the blood-brain barrier (BBB), rendering them ineffective for detoxifying SM in the brain and highlighting the need for lipophilic scavengers.

Development of a xanthene-based NIR fluorescent probe for accurate and sensitive detection of γ-glutamyl transpeptidase in cancer diagnosis and treatment.

γ-Glutamyl transpeptidase (GGT) regulates glutathione (GSH), essential for cell functions and linked to cancer. High GGT levels in tumors make it a valuable cancer biomarker. Current GGT detection methods often lack sensitivity and specificity.

Natural product-inspired [3 + 2] cycloaddition-based spirooxindoles as dual anticancer agents: synthesis, characterization, and biological evaluation by and methods.

Breast and colorectal cancers are the most common tumors, with high recurrence and low survival rates. We designed and synthesized a series of spirooxindole pyrrolidinyl derivatives, which were further evaluated for anti-proliferative activity using MDA-MB-468 and HCT 15 cell lines. The best inhibitor of this class, compound 6f, showed a very good inhibition potency, both on the MDA-MB-468 and HCT 15 cells as confirmed by molecular docking and molecular dynamic studies that predicted its binding mode into the active site of the targets.

Environmentally Sustainable Detection of Arsenic using Convolutional Neural Networks and Imidazole-Based Organic Probes: Application in Food Samples and Arsenic Album.

Arsenic contamination poses a significant health risk, particularly when it infiltrates water supplies. While current detection methods offer precise analysis, they often involve complex instrumentation not suitable for field use. This study presents a novel approach by developing two probes, A1 and A2, based on 4-diethylaminosalicyladehyde, 2-hydroxy-1-naphthaldehyde, and 1,2-diaminoanthraquinone.
