Guanidine production by plant homoarginine-6-hydroxylases

open access: yeseLife
Metabolism and biological functions of the nitrogen-rich compound guanidine have long been neglected. The discovery of four classes of guanidine-sensing riboswitches and two pathways for guanidine degradation in bacteria hint at widespread sources of ...

Fluorescent Bis(guanidine) Copper Complexes as Precursors for Hydroxylation Catalysis

open access: yesInorganics, 2018
Bis(guanidine) copper complexes are known for their ability to activate dioxygen. Unfortunately, until now, no bis(guanidine) copper-dioxygen adduct has been able to transfer oxygen to substrates.

Chiral bifunctional NHC/guanidine ligands for asymmetric hydrogenation [PDF]

open access: yes, 2023
We report the synthesis of chiral N-heterocyclic carbene/guanidine bifunctional ligands from readily available amino alcohols. The resulting chiral bifunctional catalysts are active in an asymmetric hydrogenation of ketones, and stereoinduction by the ...

Facilitatory actions of guanidine on synaptic transmission in mammalian brain slices [PDF]

open access: yes, 1979
Guanidine administration may be beneficial in the treatment of amyotrophic lateral sclerosis and related diseases; however, the actions of guanidine on the mammalian central nervous system have not been investigated.

Effects of guanidine on synaptic transmission in the spinal cord of the frog [PDF]

open access: yes, 1977
The effects of guanidine on motoneurons of the isolated frog spinal cord were studied by adding the drug to the solution bathing the cord during intracellular recording. Guanidine (5·10–4 M) did not alter the membrane potential of motoneurons.
