Basic Information of Guanidine hydrochloride

Chemical Name: Guanidine hydrochloride

Cas No.: 50-01-1

Molecular Formula: CH5N3.HCl

Chemical Structure:



Guanidinium chloride or guanidine hydrochloride, usually abbreviated GuHCl and sometimes GdnHCl or GdmCl, is the hydrochloride salt of guanidine. Guanidinium chloride is a strong chaotrope and one of the strongest denaturants used in physiochemical studies of protein folding. Guanidine Hydrochloride also has the ability to decrease enzyme activity and increase the solubility of hydrophobic molecules. At high concentrations of guanidinium chloride (e.g., 6 M), proteins lose their ordered structure, and they tend to become randomly coiled, i.e. they do not contain any residual structure. However, at concentrations in the millimolar range in vivo, guanidinium chloride has been shown to "cure" prion positive cells (i.e. cells exhibiting a prion positive phenotype revert to a prion negative phenotype). This is the result of inhibition of the Hsp104 chaperone protein known to play an important role in prion fiber fragmentation and propagation.

Guanidine hydrochloride is indicated for the reduction of the symptoms of muscle weakness and easy fatigability associated with Eaton-Lambert syndrome. It is not indicated for treating myasthenia gravis. It apparently acts by enhancing the release of acetylcholine following a nerve impulse. It also appears to slow the rates of depolarization and repolarization of muscle cell membranes. Initial dosage is usually between 10 and 15 mg/kg (5 to 7 mg/pound) of body weight per day in 3 or 4 divided doses. This dosage may be gradually increased to a total daily dosage of 35 mg/kg (16 mg/pound) of body weight per day or up to the development of side effects. Side effects include increased peristalsis and diarrhea. Fatal bone-marrow suppression, apparently dose related, can occur with guanidine.
