• 产品描述： HA15 is a potent and specific inhibitor of ER chaperone BiP/GRP78/HSPA5, inhibits the ATPase activity of BiP, with anti-cancerous activity

• 靶点： BiP/GRP78/HSPA5;Apoptosis; GPR; Others; HSP; Autophagy

• 体外研究：
  HA15 (10 μM; 1-24 hours) induces an early endoplasmic reticulum stress (ER Stress). 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. HA15 (1-10 μM; 24 hours) induces apoptosis in A375 cells. HA15 (1-24 μM; 24 hours) induces autophagy. 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. No deleterious effects on the viability of normal human melanocytes or human fibroblasts were observed with low or high doses of HA15. Cell Viability 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. Apoptosis Analysis Cell Line: A375 cells Concentration: 1 μM, 5 μM, 10 μM Incubation Time: 24 hours Result: Induces apoptosis. Cell Autophagy Assay 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 Cell Line: A375 cells Concentration: 10 μM Incubation Time: 1 hour, 4 hours, 10 hours, 24 hours Result: Exhibited a rapid ind

• 体内研究：
  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. HA15 (0.7 mg/mouse; i.p.; 5 days/week) suppresses MPM tumor growth in vivo. Animal Model: 6-weeks female BALB/c nu/nu (nude) mice with A375 melanoma cells xenograft[ 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) Dosage: 0.7 mg/mouse Administration: Intraperitoneal injection, 5 days/week, for 5 weeks Result: Suppressed MPM tumor growth.
