Catalog No. T11553Cas No. 161374-55-6
Alias SBi4211 dimethanesulfonate
Heptamidine dimethanesulfonate (SBi4211 dimethanesulfonate) serves as a potent inhibitor related to Pentamidine, targeting the calcium-binding protein S100B with a dissociation constant (Kd) of 6.9 µM. It demonstrates specificity by preferentially killing melanoma cells overexpressing S100B compared to cells lacking this protein. Additionally, Heptamidine is employed as a valuable research tool in the study of Myotonic dystrophy (DM).

| Description | Heptamidine dimethanesulfonate (SBi4211 dimethanesulfonate) serves as a potent inhibitor related to Pentamidine, targeting the calcium-binding protein S100B with a dissociation constant (Kd) of 6.9 µM.

| Targets&IC50 | S100B:(kd)6.9 μM |
| In vitro | Heptamidine rescues the mis-splicing of minigene reporters in a HeLa cell DM1 model (EC50: 15 μM). 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 [2]. |
| In vivo | Heptamidine (i.p.; 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 [2]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
