2-Hydroxypyridine

2-Hydroxypyridine sodium salt

C5H5NO (95.03711200000001)


This colourless crystalline solid is used in peptide synthesis. It is well known to form hydrogen bonded structures somewhat related to the base-pairing mechanism found in RNA and DNA. It is also a classic case of a molecule that exists as tautomers. Some publications only focus one of the two possible patterns, and neglect the influence of the other. For example, to calculation of the energy difference of the two tautomers in a non-polar solution will lead to a wrong result if a large quantity of the substance is on the side of the dimer in an equilibrium. The direct tautomerisation is not energetically favoured, but a dimerisation followed by a double proton transfer and dissociation of the dimer is a self catalytic path from one tautomer to the other. Protic solvents also mediate the proton transfer during the tautomerisation. Acquisition and generation of the data is financially supported in part by CREST/JST.

Anabasine is a botanical?pesticide?nicotine, acts as a full agonist of nicotinic acetylcholine receptors (nAChRs). Anabasine induces depolarization of TE671 cells endogenously expressing human fetal muscle-type nAChRs (EC50=0.7 μM)[1][2].
