ChEBI: HA15 is a sulfonamide resulting from the formal condensation of the sulfonic acid group of 5-(dimethylamino)naphthalene-1-sulfonic acid with the aniline nitrogen of 3-(2-acetamido-1,3-thiazol-4-yl)aniline. It has been reported that by triggering an endoplasmic reticulum (ER) stress response, HA15 can reduce the viability of melanoma cells without being toxic to normal cells. It has a role as an antineoplastic agent. It is a sulfonamide, a member of 1,3-thiazoles, a member of acetamides, a tertiary amino compound, an aminonaphthalene and a biaryl. | [Biological Activity]
HA15 is a small molecule that specifically targets HSPA5 (Heat shock 70kDa protein 5), also known as BiP (Immunoglobulin heavy-chain-binding protein) or Grp78 (glucose-regulated protein 78). Antitumor activity in melanoma cells tested, including cells isolated from patients and cells resistant to BRAF inhibitors. | [in vitro]
HA15 induces endoplasmic reticulum stress in cells in vitro, leading to cancer cell death; in melanoma cells, it overcomes its resistance to BRAF inhibitors. | [in vivo]
In xenograft mouse models (bearing melanoma cells sensitive or resistant to BRAF inhibitors), HA15 was able to induce endoplasmic reticulum stress leading to cancer cell death. | [target]
