Cat.No.S8299

HA15 is a molecule that targets specifically HSPA5 (Heat shock 70kDa protein 5) also known as BiP (Immunoglobulin heavy-chain-binding protein) or Grp78 (glucose-regulated protein 78). This compound displays anti-cancerous activity on all melanoma cells tested, including cells isolated from patients and cells that developed resistance to BRAF inhibitors.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	BiP/GRP78/HSPA5
In vitro	HA15 induces ER stress leading to cancer cell death in vitro and overcomes BRAF inhibitor resistance in melanoma cells.
In vivo	HA15 induces ER stress leading to cancer cell death and exhibits strong efficacy in xenograft mouse models with melanoma cells either sensitive or resistant to BRAF inhibitors.
