Product Description

EMD638683 is a potent inhibitor of SGK1 with an IC50 of 3 μM. EMD638683 treatment significantly augmented the radiation-induced decrease of forward scatter, increase of phosphatidylserine exposure, decrease of mitochondrial potential, increase of caspase 3 activity, increase of DNA fragmentation and increase of late apoptosis. EMD638683 promotes radiation-induced suicidal death of colon tumor cells in vitro and decreases the number of colonic tumors following chemical carcinogenesis in vivo.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
EMD638683 is a conjugate of SGK1. Half-maximum effect (IC50) of EMD638683's inhibition of NDRG1 (N-Myc downstream regulatory gene 1) needs the addition of 3.35 μM EMD638683 to the cell culture medium. Moreover, three cAMP topologies in control and EMD638683 (50 μM) are inhibited by EMD63868: SGK isoforms SGK2 and SGK3, mitogen- and casein-activated protein kinase 1 (MSK1), and protein kinase C-related protein kinase 2 (PKR2) [1]. irradiation markedly raised the proportion of CaCo-2 cells treated with late cells. ) treated CaCo-2 cells. The percentage of CaCo-2 cells tended to rise with treatment with EMD638683 alone. A small number received EMD638683 treatment following radiation. In light of this, EMD638683 therapy greatly increased UV radiation following irradiation [2].
ln Vivo
In comparison to the night-treated group, the EMD638683-treated group's night weight was much lower and its night length was significantly longer. This result suggests that, following chemical action, EMD638683 has an impact on tumor growth. Additionally, the group receiving EMD treatment saw a considerable decrease in stomach weight. was given EMD638683 treatment, which considerably lowered the quantity of tumors that grew as a result of food processing [2]. In lung cancer patients, monocrotaline (MCT)-guided vascular transplantation is stopped from progressing by EMD638683 (20 mg/kg, gavage). According to the hemodynamic profile, the EMD638683 therapy was found to lower the right ventricular hypertrophy index (RVHI) (0.27 vs. 0.41; P<0.05; n = 6) and right ventricular systolic pressure (15.8 vs. 28.2 mmHg; P<0.05; n = 6) as compared to the control dose [3].

  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
