Rotigaptide (ZP123) is a novel and specific modulator of connexin 43 (Cx43). Rotigaptide prevents the uncoupling of Cx43-mediated gap junction communication and normalizes cell-to-cell communication during acute metabolic stress. Rotigaptide is a potent antiarrhythmic peptide (AAP) with improved stability and has the potential for the investigation of cardiac arrhythmias-specifically atrial fibrillation.

Description

Rotigaptide (ZP123) is a novel and specific modulator of connexin 43 (Cx43). Rotigaptide prevents the uncoupling of Cx43-mediated gap junction communication and normalizes cell-to-cell communication during acute metabolic stress. Rotigaptide is a potent antiarrhythmic peptide (AAP) with improved stability and has the potential for the investigation of cardiac arrhythmias-specifically atrial fibrillation[1][2].

IC50 & Target

IC50: connexin 43 (Cx43)[1]
In Vitro

Rotigaptide (100 nM; 24 hours) has a positive effect on cycloheximide-mediated decrease in Cx43 protein levels in cultured neonatal ventricular myocytes[1].
Rotigaptide (100 nM; 24 hours) dose not affect INS-1 cell apoptosis itself. And it significantly reduces apoptosis in cytokine-exposed cells ~10% at IL-1b concentrations above 15 pg/ml in rat insulin-producing INS-1 cells[2].

Western Blot Analysis[1]

Cell Line: Neonatal cardiomyocytes
Concentration: 100 nM
Incubation Time: 24 hours
Result: Partially prevented the loss of Cx43 protein expression in neonatal cardiomyocytes.

Apoptosis Analysis[2]

Cell Line: Cx43 deficient INS-1 cells
Concentration: 100 nM
Incubation Time: 24 hours
Result: Ameliorated cytokine-induced apoptosis associated with improved mitochondrial function.
In Vivo

Rotigaptide (intravenous administration; 300 mg/kg; single dose) treatment in mice and rats does not result in toxicity in either species.
In escalating dose studies, Rotigaptide (continuous intravenous infusion; 5-14 days) in rats (100 mg/kg) and dogs (10 mg/kg) are well tolerated and produces no compound-related effects or histological toxicological findings[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 5 mg/mL (8.10 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 5 mg/mL (8.10 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
