Description

Se-Methylselenocysteine, a precursor of Methylselenol, has potent cancer chemopreventive activity and anti-oxidant activity. Se-Methylselenocysteine is orally bioavailable, and induces apoptosis[1][2].

IC50 & Target

BACE1

 

In Vitro

Se-Methylselenocysteine (100-400 μM; 3 days) induces apoptosis in SKOV-33 cells[1].
? Se-Methylselenocysteine (100-400 μM; 3 days) induces caspase-3 mediated apoptosis[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Apoptosis Analysis[1]

Cell Line: SKOV-3 cells
Concentration: 100, 200, 400 μM
Incubation Time: 3 days
Result: Resulted in a markedly increased accumulation of Sub-G1 phase, which occurred in both SeMSC concentration and culture time-dependent.

Western Blot Analysis[1]

Cell Line: SKOV-3 cells
Concentration: 100, 200, 400 μM
Incubation Time: 3 days
Result: Resulted in a decrease in the expression of the 32 kDa form of procaspase-3.
In Vivo

Se-Methylselenocysteine (0.2?mg/mouse; p.o.; daily for 14 days) potentiates the antitumour activity of CDDP and Cyclophosphamide in nude mice bearing human FaDu and A253 head and neck xenografts[2].
? Alzheimer's disease (AD) mice are treats with Se-Methylselenocysteine (0.75 mg/kg BW per day) in their drinking water for 10 months. Se-Methylselenocysteine reduces oxidative stress and neuro-inflammation; Se-Methylselenocysteine modulates the distribution and levels of several metal ions; Se-Methylselenocysteine decreases amyloid-β peptide (Aβ) generation by inhibiting the expression of its precursor protein APP and β-secretase (BACE1), and attenuates tau hyperphosphorylation and neurofibrillary tangles (NFT) formation via promoting protein phosphatase 2A (PP2A) activity, thereby preserving synaptic proteins and neuron activities and finally improving spatial learning and memory deficits in AD model mice[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
