在氮氣保護下，將13.75 g L-高絲氨酸內(nèi)酯鹽酸鹽與40 mL N,N-二甲基甲酰胺(DMF)混合，攪拌至完全溶解。隨后，將15.2 g硒酸甲酯（CAS:37773-10-7）溶于20 mL DMF中，緩慢加入上述反應(yīng)體系。加熱回流反應(yīng)2小時。反應(yīng)完成后，用乙酸水溶液調(diào)節(jié)反應(yīng)體系的pH至6.0，析出白色固體。將所得固體溶于水和乙醇的混合溶劑中進行重結(jié)晶，得到L-硒代蛋氨酸。該合成路線的總收率為72.11%，產(chǎn)物的化學純度大于99%，對映體過量值(ee)大于99%。

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 IC 50 (1-90 μM) at 72 h than normal prostate cells (>500 μM). |
Apoptosis Analysis
