生物活性

L-SelenoMethionine, an L-isomer of Selenomethionine, is a major natural food-form of selenium. L-SelenoMethionin is a cancer chemopreventive agent that can reduce cancer incidence by dietary supplementation and induce apoptosis of cancer cells. L-SelenoMethionine also can increase expression of glutathione peroxidase.

体外研究

L-SelenoMethionine (1-500 μM; 24-72 h) is selectively inhibits the growth of prostate cancer cells, compared with normal cells.
L-SelenoMethionine (500 μM; 48 h) induce apoptosis in prostate cancer cells.
L-SelenoMethionine (500 μM; 48 h) causes an increase in arrest in the G2-M phase of the cell cycle selectively in prostate cancer cells.
L-SelenoMethionine (5 μM; 24 h) mitigates gene expression associated with the cellular stress response from 10 cGy irradiation.

Cell Viability Assay

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 1, 5, 10, 50, 100, 500 μM
Incubation Time: 24, 48, 72 hours
Result: Inhibited the growth of prostate cancer cells, with a lower IC50 (1-90 μM) at 72 h than normal prostate cells (>500 μM).

Apoptosis Analysis

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 500 μM
Incubation Time: 48 hours
Result: Exhibited the highest level of DNA condensation in androgen-responsive LNCaP carcinoma cells, followed by PC-3 and DU145 cells.
Exhibited the nicked-end DNA labeling in prostate cancer cells.
Promoted the PARP cleavage in prostate cancer cells.

Cell Cycle Analysis

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 500 μM
Incubation Time: 48 hours
Result: Increased the sub-G0-G1 cell fraction of LNCaP (41.5%), PC-3 (12.1%), and DU145 cells (11.2%).
Caused a significant increases in G2 cells , particularly in LNCaP (13%), PC-3 (32%), and DU145 (20%) cells.

RT-PCR

Cell Line: Human thyroid epithelial cells (HTori-3)
Concentration: 5 μM
Incubation Time: 24 hours
Result: Downregulated the CDC6, GADD45A, FAS and ATF3 in irradiated cells.
体内研究

L-SelenoMethionine (0.06-12 μg/g diet; p.o. for 3 d) partially or completely prevent the decrease in the serum or plasma levels of total antioxidants in rats exposed to gamma rays, protons or HZE particles.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
