Rimcazole dihydrochloride

Rimcazole (BW 234U) dihydrochloride is a carbazole derivative that acts in part as a sigma (σ) receptor antagonist. Rimcazole dihydrochloride also binds with moderate affinity to the dopamine transporter and inhibit dopamine uptake. Rimcazole dihydrochloride can attenuate cocaine-induced locomotor activity and sensitization. Rimcazole dihydrochloride also can be used for the research of cancer[1][2][3][4].

Rimcazole (1-50 μM; 24-48 h) concentration-dependently decreases the number HCT-116p53+/+ cells[2]. Rimcazole (50 μM; 1-24 h) dihydrochloride induces a transient accumulation of HIF-1α protei in cancer cells (HCT-116p53+/+ and MDA MB 231 cells) but not in normal human dermal fibroblasts[2]. Western Blot Analysis[2] Cell Line: HCT-116p53+/+ cells Concentration: 50 μM Incubation Time: 1, 2, 3, 5, 6, 24 hours Result: Accumulation of HIF-1α protein, maximal at 6 h. No change in p53 protein levels. HIF-1α protein levels returned to normal steady-state levels within 24 h.
