| 生物活性 | Heptamidine dimethanesulfonate (SBi4211 dimethanesulfonate) is a potent Pentamidine-related inhibitor of the calcium-binding protein S100B (Kd=6.9 μM), selectively kills melanoma cells with S100B over those without S100B. Heptamidine is a useful tool for the investigation of Myotonic dystrophy (DM). | ||||||||||||||||
| 体外研究 |
Heptamidine is a Pentamidine-S100B complex, two molecules of pentamidine bind per monomer of S100B, which performs to be an inhibitor for S100B.Heptamidine (20 μM) does not decrease CUG levels significantly when compares to Propamidine and Pentamidine, and exhibits cytotoxic at concentrations above 17.5 μM in HeLa cells expressing 960 CUG repeats.Heptamidine rescues mis-splicing of minigene reporters in a HeLa cell DM1 model with an EC50 value of 15 μM. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
| 体内研究 |
Heptamidine (intraperitoneal injection; 20 or 30 mg/kg; 7 days) causes a dose-dependent reduction of exon 7a inclusion in HSALR mice, returning to wild type levels (6±1%) when at 20 mg/kg dose, the myotonia is reduced from grade 3 to grade 1 (occasional myotonic discharge) or grade 0 at both 20 or 30 mg/kg. 西域 has not independently confirmed the accuracy of these methods. They are for reference only.
