    HA15 purchased from MedChemExpress. Usage Cited in: Sci Rep. 2020 Jun 30;10(1):10604.  [Abstract]

    HA15, a GRP78 inhibitor, to inhibit GRP78, and finds that inhibition of GRP78 abolished the downregulation of Col1 and α-SMA in response to UCHL1 siRNA in CFs with TGF-β1 stimulation.

    Description

    HA15 is a potent and specific inhibitor of ER chaperone BiP/GRP78/HSPA5, inhibits the ATPase activity of BiP, with anti-cancerous activity[1].

    IC50 & Target

    BiP/GRP78/HSPA5[1]

    In Vitro

    HA15 (10 μM; 1-24 hours) induces an early endoplasmic reticulum stress (ER Stress)[1].
    ? HA15 (0-10μM; 24 hours) decreases melanoma cell viability in a dose-dependent manner compared with control conditions (DMSO), with an IC50 of 1-2.5 μM in? A375 cells[1].
    ? HA15 (1-10 μM; 24 hours) induces apoptosis in A375 cells[1].
    ? HA15 (1-24 μM; 24 hours) induces autophagy[1].
    ? HA15 (10 μM; 48 hours) has high efficiency in inducing cell death and ER stress in BRAF-inhibitor-resistant melanoma cells. And HA15 inhibits tumor growth through autophagic and apoptotic mechanisms initiated by ER stress[1].
    ? No deleterious effects on the viability of normal human melanocytes or human fibroblasts were observed with low or high doses of HA15[1].

    Cell Viability Assay[1]

    Cell Line: A375 cells
    Concentration: 1 μM,2.5 μM,5 μM,7.5 μM,10 μM
    Incubation Time: 24 hours
    Result: Decreased melanoma cell viability in a dose-dependent manner compared with control conditions (DMSO) in A375 cells.

    Apoptosis Analysis[1]

    Cell Line: A375 cells
    Concentration: 1 μM, 5 μM, 10 μM
    Incubation Time: 24 hours
    Result: Induces apoptosis.

    Cell Autophagy Assay[1]

    Cell Line: A375 cells
    Concentration: 1 μM, 4 μM, 10 μM, 24 μM
    Incubation Time: 24 hours
    Result: Increased LC3B-II expression after 1 hour and persisted after 24 hours, enhanced the expression level of Beclin 1, clearly be indicated that induces autophagy.

    Western Blot Analysis[1]

    Cell Line: A375 cells
    Concentration: 10 μM
    Incubation Time: 1 hour, 4 hours, 10 hours, 24 hours
    Result: Exhibited a rapid induction within 1 hour of the ER stress markers (phosphorylation of PERK and elF2α and a weak increase in ATF4 and CHOP expression)
    In Vivo

    HA15 (0.7 mg/mouse/day; i.h.; over 2 weeks) inhibits melanoma tumor development in mice, induces no apparent toxicity and no change in their behavior, body mass, or liver mass, suggesting an absence of hepatomegaly[1].
    ? HA15 (0.7 mg/mouse; i.p.; 5 days/week) suppresses MPM tumor growth in vivo[3].

    Animal Model: 6-weeks female BALB/c nu/nu (nude) mice with A375 melanoma cells xenograft[1]
    Dosage: 0.7 mg/mouse/day
    Administration: Subcutaneous injection; over a period of 2 weeks
    Result: Attenuated the development of tumors.
    Animal Model: Mouse, NSG (NOD-scid IL2Rγnull)[3]
    Dosage: 0.7 mg/mouse

    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.
