Customer Review

    EC359 purchased from MCE. Usage Cited in: Adv Sci (Weinh). 2021 Feb 25;8(9):2003535.  [Abstract]

    Western blot is applied to measure protein expression changes in mESCs cultured for 3 d on gelatin, with or without EC359 (150 μM). Addition of EC359 significantly decreases the LIFR-mediated activation of p-STAT3 and phospho-protein kinase B (p-AKT) whereas increased phospho-extracellular signal-regulated kinase (p-ERK) expression in the LIF+ group.

    生物活性

    EC359 is a potent, selective, high affinity and orally active leukemia inhibitory factor receptor (LIFR) inhibitor with a Kd of 10.2 nM, which directly interacts with LIFR to effectively block LIF/LIFR interactions[1]. EC359 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

    IC50 & Target

    Kd: 10.2 nM (leukemia inhibitory factor receptor)[1]

    体外研究
    (In Vitro)

    EC359 (0-100 nM; 3 days; BT-549, SUM-159, MDA-MB-231, MDA-MB-468, and HCC1806 cells) treatment reduces cell viability in a dose-dependent manner[1].
    ? EC359 (20 nM, 25 nM; 72 hours; MDA-MB-231 and BT-549 cells) treatment significantly increases caspase-3/7 activity and Annexin V-positive cells in both MDAMB-231 and BT-549 cells. EC359 exhibits significant inhibitory activity on invasion and promotes apoptosis of TNBC cells[1].
    ? EC359 (100 nM; 12 hours; BT549 cells) treatment significantly reduces the expression of several (such as STAT1 TGFB1, JUNB, MCL-1, etc) known STAT3 target genes[1].
    ? EC359(100 nM; 1 hour; MDA-MB-231 and BT-549 cells)? treatment substantially reduces the LIF activation of STAT3, also reduces the STAT3 activation by OSM and CNTF. EC359 treatment substantially decreases the phosphorylation of AKT, mTOR, S6, and ERK1/2 in MDA-MB231 and BT-549 cells. EC359 treatment also increases the phosphorylation of proapoptotic p38MAPK in BT549 cells[1].

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

    (In Vivo)

    EC359 (5 mg/kg; subcutaneous injection; 3 days per week; for 25 days; female athymic nude mice) treatment significantly reduces the tumor progression. The body weights of mice in EC359-treated groups remains unchanged confirming the low toxicity of EC359[1].

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

    Animal Model: 8-week-old female athymic nude mice with MDA-MB-231 cells[1]
    Dosage: 5 mg/kg
    Administration: Subcutaneous injection; 3 days per week; for 25 days
    Result: Significantly reduced the tumor progression.

    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.
