| Use | HA15 is a highly effective and specific inhibitor of endoplasmic reticulum chaperone protein BiP/GRP78/HSPA5, which can inhibit the ATPase activity of BiP and has anti-tumor activity. |
| In vitro study | HA15 induces endoplasmic reticulum stress in cells in vitro, leading to cancer cell death; In melanoma cells, it overcomes resistance to BRAF inhibitors. |
| In vivo study | In a xenograft mouse model (harboring melanoma cells that are sensitive or resistant to BRAF inhibitors),HA15 is able to induce endoplasmic reticulum stress leading to cancer cell death. |

| biological activity | HA15 is a small molecule that specifically targets HSPA5 (Heat shock 70kDa protein 5), which can also be called BiP (Immunoglobulin heavy-chain-binding protein) or Grp78 (glucose-regulated protein 78). It has anti-tumor activity in the detected melanoma cells, including cells isolated from patients and cells resistant to BRAF inhibitors. |

| Target | Value |
| in vitro study | HA15 induces endoplasmic reticulum stress in in vitro cells, leading to cancer cell death; in melanoma cells, overcome its resistance to BRAF inhibitors. |
| In vivo studies | In a xenograft mouse model (carrying melanoma cells that are sensitive or resistant to BRAF inhibitors),HA15 can induce endoplasmic reticulum stress, which leads to cancer cell death. |
