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.

PRECURSORS OF MIMOSINE IN MIMOSA PUDICA
Canadian Journal of Biochemistry, 1965In 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.

Journal of Agricultural and Food Chemistry, 2011 The inhibitory effect of mimosine on polyphenoloxidase (PPO) from the cephalothorax of Pacific white shrimp (Litopenaeus vannamei) was studied. Mimosine showed inhibitory activity toward PPO from white shrimp with an apparent molecular weight of 210 kDa ...

Effect of mimosine on the rat fetus
Teratology, 1970AbstractGroups of 16 pregnant rats per treatment were fed ad libitum a basal diet containing 0, 0.3, 0.5, or 0.7% mimosine or allowed a restricted intake of the diet with no mimosine until killed on day 20 of gestation.Incremental increases of mimosine caused significant (P<0.01) decreases in daily feed consumption, weight gain per unit of food, and

Inhibition of Growth of Hair by Mimosine
Nature, 1962Loss 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 ...

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, 1964AbstractDegradation 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.

Polarographic investigation of mimosine
Recueil des Travaux Chimiques des Pays-Bas, 1950AbstractA 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 rapid colorimetric method for the determination of mimosine
Archives of Biochemistry and Biophysics, 1951Abstract A rapid colorimetric method has been described for the quantitative determination of mimosine by using activated carbon as a decolorizing agent and measuring the intensity of mimosine-ferric chloride color produced.

The Dual Effect of Mimosine on DNA Replication
Experimental Cell Research, 1997The plant amino acid, mimosine, is an extremely effective inhibitor of DNA replication in mammalian cells, but the mechanism by which this inhibition is achieved is unknown. The drug has been proposed either to inhibit initiation at origins of replication or to inhibit chain elongation by lowering nucleotide pool levels.
