Product Description

HA15 (HA-15) is an inhibitor of chaperone BiP (Binding immunoglobulin protein, GRP78) with anticancer activity. It specifically targets chaperone BiP/GRP78/HSPA5. HA15 causes ER stress, which in turn triggers autophagic and apoptotic processes, ultimately resulting in the death of cancer cells. In xenograft mouse models containing melanoma cells that were either sensitive or resistant to BRAF inhibitors, HA15 also demonstrated significant efficacy. All melanoma cells tested, including patient-isolated cells and cells resistant to BRAF inhibitors, showed anti-cancerous activity in response to HA15. HA15 demonstrated efficacy against various types of solid and liquid tumors. In xenograft mouse models containing melanoma cells that were either sensitive or resistant to BRAF inhibitors, HA15 also demonstrated significant efficacy.

Biological Activity I Assay Protocols (From Reference)
Targets
BiP/GRP78/HSPA5
ln Vitro
HA15 (10 μM; 1-24 hours)auses an early endoplasmic reticulum stress (ER Stress) [1].
HA15 (0-10μM; 24 hours) has an IC50 of 1-2.5 μM in A375 cells and reduces melanoma cell viability in a dose-dependent manner when compared to control conditions (DMSO)[1].
HA15 (1-10 μM; 24 hours) causes apoptosis in A375 cells[1].
HA15 (1-24 μM; 24 hours) induces autophagy[1].
HA15 (10 μM; 48 hours) exhibits a high degree of efficacy in causing ER stress and cell death in melanoma cells that are resistant to BRAF inhibitors. Furthermore, through apoptotic and autophagic pathways triggered by ER stress, HA15 prevents the growth of tumors[1].
HA15 at low or high doses did not negatively impact the viability of human fibroblasts or normal human melanocytes[1].
ln Vivo
HA15 (0.7 mg/mouse/day; i.h.; over 2 weeks) prevents the growth of melanoma tumors in mice, causes no discernible toxicity, and has no effect on their behavior, body mass, or liver mass, indicating the lack of hepatomegaly[1].
HA15 (0.7 mg/mouse; i.p.; 5 days/week) inhibits the growth of MPM tumors in vivo[3].
Cell Assay
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.
Animal Protocol
6-weeks female BALB/c nu/nu (nude) mice with A375 melanoma cells xenograft[1]
0.7 mg/mouse/day
Subcutaneous injection; over a period of 2 weeks

Solubility Data
Solubility (In Vitro)
DMSO: ~10 mM in DMSO
Water: <1 mg/mL
Ethanol: <1 mg/mL
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.36 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.1433 mL 10.7163 mL 21.4326 mL
5 mM 0.4287 mL 2.1433 mL 4.2865 mL
10 mM 0.2143 mL 1.0716 mL 2.1433 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • 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)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
