In cultured vascular cells, l-mimosine acted as a prolyl 4-hydroxylase inhibitor. L-mimosine inhibited prolyl hydroxylase activity in rat and human smooth muscle cells (SMC) dose-dependently, and at concentrations of 400–500 M reduced hydroxyprolyl generation by 80–90%. At that concentration, [3H]proline incorporation decreased by about 20% in human SMC while increasing by about 20% in rat SMC. These findings showed that L-mimosine very specifically inhibited prolyl hydroxylation.
| ln Vitro |
L-Mimosine reduces cell proliferation by halting the cell cycle in PC-3 cells at the G1 phase and in LNCaP cells at the S phase. [1] L-mimosine, a prolyl hydroxylase (PHD) inhibitor, stimulates the synthesis of VEGF and boosts the proangiogenic potential of cells derived from dental pulp. [2]

| ln Vivo |
In Sprague-Dawley rats, L-mimosine (50 mg/kg i.p.) significantly increases the expression of HIF-1alpha in the kidneys and noticeably improves the natriuretic response to renal perfusion pressure. [3]

| Enzyme Assay |
In rats, it interfered with the reconstitution of the active human prolyl 4-hydroxylase with an IC50 value of 120 µM.

| Cell Assay |
Cell proliferation in response to L-mimosine is measured using a [3H]thymidine incorporation assay. In this test, RPMI-1640 medium with 10% FCS and various concentrations of L-mimosine (0-800 μM) are cultured in each well of a 12-well plate with 1 × 104 cells each. Each well of the 12-well plate receives 0.5 μCi/ml of [3H[3H]thymidine following the necessary incubation times (24 and 48 h). After that, the cells are incubated for 4 hours at 37°C in a humidified 5% CO2 environment. The following step involves washing the cells twice in cold phosphate-buffered saline (PBS) and once more in cold 5% trichloroacetic acid. By adding 0.5 ml of 0.5 N NaOH, cells are lysed. In a liquid scintillation analyzer, 400 μl of the solubilized cell solution are combined with 4 ml of scintillation cocktail, and the results are then tallied. Quadruplicates of each sample were examined.

| Additional Infomation |
L-mimosine is an L-alpha-amino acid that is propionic acid substituted by an amino group at position 2 and a 3-hydroxy-4-oxopyridin-1(4H)-yl group at position 3 (the 2S-stereoisomer). It a non-protein plant amino acid isolated from Mimosa pudica. It has a role as an EC 1.14.18.1 (tyrosinase) inhibitor and a plant metabolite. It is a non-proteinogenic L-alpha-amino acid and a member of 4-pyridones. It is functionally related to a propionic acid. It is a conjugate acid of a L-mimosine(1-). It is a tautomer of a L-mimosine zwitterion.
Mimosine is an antineoplastic alanine-substituted pyridine derivative isolated from Leucena glauca. L-mimosine has been reported in Arabidopsis thaliana, Euglena gracilis, and Caenorhabditis elegans with data available. 3-Hydroxy-4-oxo-1(4H)-pyridinealanine. An antineoplastic alanine-substituted pyridine derivative isolated from Leucena glauca. Mechanism of Action Mimosine causes inhibition of DNA replication, changes in the progression of the cells in the cell cycle, and apoptosis. Mimosine appears to introduce breaks into DNA. Mimosine is an iron/zinc chelator. Iron depletion induces DNA double-strand breaks in treated cells, and activates a DNA damage response that results in focal phosphorylation of histones. This leads to inhibition of DNA replication and/or DNA elongation. Some studies indicate that mimosine prevents the initiation of DNA replication, whereas other studies indicate that mimosine disrupts elongation of the replication fork by impairing deoxyribonucleotide synthesis by inhibiting the activity of the iron-dependent enzyme ribonucleotide reductase and the transcription of the cytoplasmic serine hydroxymethyltransferase gene (SHMT). Inhibition of serine hydroxymethyltransferase is moderated by a zinc responsive unit located in front of the SHMT gene. |
