Inhibition of Growth of Hair by Mimosine

Nature, 1962
Loss of hair in animals following ingestion of seeds and foliage of Leucaena glauca was first reported in 18971. Sudden loss of hair in native women has been ascribed to consumption of Leucaena glauca seeds2. The toxic principle contained in this plant is a water-soluble amino-acid termed leucenol, and is identical with mimosine obtained from Mimosa ...

Antidermatophytic and bacterial activity of mimosine

Phytotherapy Research, 2005
Mimosine, a non-protein aromatic amino acid was tested at 100, 50 and 25 microg/mL on some human pathogenic bacteria and fungi. Mimosine exhibited total lethality towards Trichophyton tonsurans and Trichophyton rubrum at 100 microg/mL. Among the tested bacteria Staphylococcus aureus was inhibited to a larger extent than the other bacteria.

The Chemistry and Biological Activities of Mimosine: A Review

Phytotherapy Research, 2016
Mimosine [β‐[N‐(3‐hydroxy‐4‐oxypyridyl)]‐α‐aminopropionic acid] is a non‐protein amino acid found in the members of Mimosoideae family. There are a considerable number of reports available on the chemistry, methods for estimation, biosynthesis, regulation, and degradation of this secondary metabolite.

Mimosine Content of Leucaena leucocephala and the Sensitivity of Rhizobium to Mimosine

Journal of Plant Physiology, 1985
Mimosine was qualitatively and quantitatively estimated from the different parts of Leucaena leucocephala strains K-8 and K-67. The amount of mimosine as percentage of dry weight in the two strains were, respectively, as follows: seeds, 6.82, 9.98; old leaves, 1.5, 1.33; young leaves, 2.85, 3.33; main root, 1.13, 1.02; lateral roots, 1.46, 1.17; stems,

Mimosine (leucaenine) 5th communication )

Recueil des Travaux Chimiques des Pays-Bas, 1950
AbstractThe identity of mimosine from Mimosa pudica and of l‐leucaenine from Leucaena glauca Bentham is proved by means of a mixed melting point and Debije‐Scherrer diagram.The action of diazomethane on the dihydrochloride of mimosine methyl ester leads to a total degradation of the molecule, by which the pyridine ring is broken.

PRECURSORS OF MIMOSINE IN MIMOSA PUDICA

Canadian Journal of Biochemistry, 1965
In Mimosa pudica L. both L- and DL-lysine serve as specific precursors of the -γ-pyridone nucleus of mimosine. Succinic acid is also incorporated into the nucleus. Glycerol and glyceric acid enter the side chain of mimosine. An improved method for the isolation of mimosine from M. pudica is described.

Polarographic investigation of mimosine

Recueil des Travaux Chimiques des Pays-Bas, 1950
AbstractA polarographic investigation of mimosine was made in order to obtain more information on its polar structure. The polarographic behaviour of mimosine is abnormal, but it is possible to give a reaction scheme explaining these phenomena.

A SYNTHESIS OF MIMOSINE

Canadian Journal of Chemistry, 1962
DL-Mimosine has been sinthesized by debenzylation and detosylation of the product obtained by condensation of 3-benzyloxy-4-pyrone with β-amino-α-tosylaminopropionic acid.A new method for the isolation of mimosine from Leucaena glauca Benth. is described.

Biosynthesis of mimosine

Phytochemistry, 1964
Abstract Administration of [2-14C]- dl -lysine to Leucaena glauca results in incorporation of radioactivity into mimosine, pipecolic acid and 5-hydroxypipecolic acid. Degradation of the mimosine reveals that 95% of the radioactivity is present in the pyridone ring.

The absolute configuration of mimosine

Recueil des Travaux Chimiques des Pays-Bas, 1964
AbstractDegradation of the plant amino acid (‐)‐mimosine yielded optically pure (+)‐α,β‐diaminopropionic acid hydrobromide identical with the acid obtained from L‐asparagine. (‐)‐Mimosine therefore belongs to the Ls‐series.
