Dihydrogen sulfide recently emerged as a biological signaling molecule with important physiological roles and significant pharmacological potential. Chemically plausible explanations for its mechanisms of action have remained elusive, however. Here, we report that H(2)S reacts with S-nitrosothiols to form thionitrous acid (HSNO), the smallest(More)
GABA was discovered to play an important role as the major inhibitory neurotransmitter in the adult mammalian CNS 60 years ago. The conformational flexibility of GABA is important for its biological function, as it has been found to bind to different receptors with different conformations. In an effort to increase the lipophilicity and to reduce(More)
A new guanidine-thiourea organocatalyst has been developed and applied as bifunctional organocatalyst in the Michael addition reaction of diethyl malonate to trans-β-nitrostyrene. Extensive DFT calculations, including solvent effects and dispersion corrections, as well as ab initio calculations provide a plausible description of the reaction mechanism.
