The reactions of hydrogen cyanide, butyronitrile, cyclopropanecarbonitrile, pivalonitrile and benzonitrile with arsenic pentafluoride and antimony pentafluoride result in the formation of 1 : 1 Lewis adducts, while malononitrile yielded both 1 : 1 and 1 : 2 Lewis adducts. All adducts were isolated and characterized by multinuclear NMR and vibrational spectroscopy, and in most cases by their X-ray crystal structures.

Wastewater contains various emerging contaminants, including heavy metals, residues of pesticides, and pharmaceuticals. Therefore, irrigation with wastewater can enhance heavy metal contamination in soil and adversely affect plant growth. To mitigate this problem, plant growth-promoting bacteria (PGPR) can improve plant growth under heavy metal stress.

Nitric oxide (NO)-donor drugs, which stimulate reduced form of soluble guanylate cyclase (sGC), have different efficacy to the arteries and veins. This study examined whether sGC activators, which activate oxidized/apo sGC, also have arteriovenous selectivity similar to that of NO-donor drugs. The mechanical responses of the isolated blood vessels were assessed using the organ chamber technique and protein expression was verified using western blotting.

Amygdalin is a plant-based cyanogenic glycoside that has been the subject of both scientific interest and controversy for decades. Traditionally used in alternative medicine for its diverse biological activities, including anticancer, where amygdalin has been explored in complementary therapy. However, clinical utilization of amygdalin remains contentious due to concerns about its safety, primarily the release of hydrogen cyanide during its metabolism.

This work describes the synthesis and characterization of new quinolone-benzothiazole hybrids, the study of their aggregation-induced emission (AIE) properties, and the use of these systems as efficient fluorescent probes for cyanide ions. These conjugated derivatives are linked through a double bond favoring electronic communication, and together with their planar geometry, can strongly aggregate under solvophobic environments, leading to aggregation and exhibiting significant AIE behavior. The double bond between electroactive units is prone to nucleophilic addition reactions by cyanide ions, selectively, conducive to turning off the fluorescence properties, making this hybrid system an efficient probe for cyanide ions.

Cyanogenic plants can release toxic hydrogen cyanide (HCN) to defend against herbivory by hydrolyzing the cyanogenic glycosides (CNGs) with its β-glucosidases (β-GLUs). Numerous studies have speculated this CNG-mediated toxicity by a plant-pest interaction manner. However, the specific toxic effect of HCN was not well-demonstrated because of the interference of other ingested metabolites.
