The coordination chemistry of guanidines and guanidinates

Coordination Chemistry Reviews, 2001
Abstract Species containing the Y-shaped CN3 unit have recently attracted increasing attention as electronically and sterically flexible ligands. Neutral guanidines [(R2N)2CNR], guanidinates(−1) [(RN)2CNR2]− and guanidinates(2) [(RN)2CNR]2− are capable of exhibiting a variety of coordination modes and a range of donor properties leading to ...

Botulism and Guanidine

New England Journal of Medicine, 1968
Abstract A 57-year-old woman with a fatal disease, presumably botulism, was treated intermittently with guanidine hydrochloride over a 20-day period. Guanidine was given because it enhances the release of acetylcholine at the neuromuscular junction. During treatment, ptosis and extraocular palsies were relieved, strength in proximal muscles improved ...

Guanidine and guanidine derivatives

1961
While the knowledge of the blood sugar lowering properties of the sulphonamide derivatives have been available for 20 years, the hypoglycaemic effect of guanidine was already known before insulin was discovered. The attempt performed 30 years ago in troducing synthalin, a derivative of guanidine, in diabetes mellitus therapy failed.

Guanidine Derivatives in Medicine

New England Journal of Medicine, 1973
FIFTY years have passed since the introduction of insulin into medicine. It is not widely known that guanidine derivatives were first used in the therapy of diabetes at about the same time, and that the effects of guanidine in a biologic system were first described nearly 100 years ago.1 Over the years, a wide variety of guanidine derivatives have ...

Antiviral Effect of Guanidine

Science, 1961
It has been found that soluble guanidine salts show an antiviral effect on poliovirus and on some other enteroviruses. The activity was first detected in a cell culture screening system when the guanidine salt of hydroxyaminomethylene malononitrile inhibited the cytopathic effect of poliovirus in cell cultures.

Guanidination of horse methemoglobin

Archives of Biochemistry and Biophysics, 1977
Abstract Reaction of horse methemoglobin with O -methylisourea at pH 10.2 results in 95% conversion of lysine residues to homoarginine. Analysis of the chymotryptic peptides showed that no single ϵ-amino group was unreactive. Guanidination decreases the dependence of the sedimentation coefficient on hydrogen ion concentration in the range of pH 8 to
