In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolized by the β-cyanoalanine synthase CYS-C1, catalyzing the conversion of...

Kisspeptin, the product of the KISS1 gene, plays an essential role in the regulation of spermatogenesis acting primarily at the hypothalamic level of the gonadotropic axis. However, the presence of kisspeptin and its canonical receptor, KISS1R, in spermatozoa has not...

Water solves the problem: The use of pure water as the reaction mixture is key for the nucleophilic addition of formaldehyde hydrazones to α-keto esters, leading to highly functionalized carbinols in high yields and short reaction times. The need for heterogeneous...

Attempts to prepare mixed-ligand zinc–zinc-bonded compounds that contain bulky C5Me5 and terphenyl groups, [Zn2(C5Me5)(Ar′)], lead to disproportionation. The resulting half-sandwich Zn(II) complexes [(η5-C5Me5)ZnAr′] (Ar′ = 2,6-(2,6-iPr2C6H3)2-C6H3, 2;...
