生物活性

Methionine (MRX-1024; D-Methionine) is an effective chemoprotective agent which can also inhibit the neuronal activity through GABAA receptor activation.

IC50 & Target

Human Endogenous Metabolite

 

体外研究
(In Vitro)

The incubation of human plasma with Methionine (D-methionine) and CP leads to the formation of a Pt-D-methionine complex independent of the order of addition. In plasma, an early CP hydrolysis product reacts with Methionine to form a 1:1 complex that is followed by the formation of a 2:1 compound at a later time point. The formation of these Pt-D-methionine species plays an important role in the processes by which Methionine protects mammalian organisms against CP-induced toxicities[2].

体内研究
(In Vivo)

When Methionine (D-methionine) is administered along with cisplatin the cell density is 0.8±0.070 (SEM), significantly larger than in rats treated with only cisplatin (P<0.01) while not significantly different from controls or from animals treated only with D-methionine (P>0.05). When Methionine is administered alone the average cell density is 0.95±0.099 (SEM) and not significantly different from controls (P>0.05)[3].

Cell Assay
[2]

Plasma (2.0 mL) is spiked with 81 mL of the CP stock solution, incubated at 37°C for 30 min and then 20 mL of theMethionine (D-methionine) stock solution (40.7 mg/mL) is added. The obtained mixture is analyzed after 10 min and 50 min of incubation at 37°C[2].

Animal Administration
[3]

Three sham controls receive 0.9% saline instead of cisplatin. Three rats receive only cisplatin. Another three rats receive Methionine (D-methionine) 30 minutes prior to treatment with cisplatin. Injection of Methionine prior to cisplatin treatment ensures that it is already taken up before cisplatin is applied. Finally, three rats are treated only with Methionine. All 12 rats are sacrificed at day 7 post-treatment. For prescreening, two further rats are treated with cisplatin alone and sacrificed 2 or 21 days later. All rats are hydrated with 0.9% saline[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.
