BPC 157 | Gastric Pentadecapeptide

Description BPC 157 is the 15-amino acide fragment of gastric peptide BPC. BPC 157 exhibits wound healing promoting and neuroprotective activity. BPC 157 maintains the integrity of the gastrointestinal mucosa without significant toxicity. BPC 157 acetate counteracts NSAIDs/insulin overdose/copper-induced toxicity. BPC 157 ameliorates specific (over)stimulated/damaged neurotransmitter systems-induced behavioral disorders through serotonergic and dopaminergic systems[1][2][3]. In Vivo BPC 157 successfully heals the intestinal anastomosis, gastrocutaneous, duodenocutaneous and colocutaneous fistulas in rats, as well as interacting with the NO-system[1]. BPC 157 (10 μg/kg, 10 ng/kg) is applied either intraperitoneally once time daily (first application immediately after surgery, last at 24 hours before sacrifice) or per-orally in drinking water (0.16 μg/ml/12 ml/day till the sacrifice).

BPC 157 successfully heals the intestinal anastomosis, gastrocutaneous, duodenocutaneous and colocutaneous fistulas in rats, as well as interacting with the NO-system[1]. BPC 157 (10 μg/kg, 10 ng/kg) is applied either intraperitoneally once time daily (first application immediately after surgery, last at 24 hours before sacrifice) or per-orally in drinking water (0.16 μg/ml/12 ml/day till the sacrifice). A multiple sclerosis suited toxic rat model, cuprizone (compared with standard, a several times higher regimen, 2.5% of diet regimen + 1 g/kg intragastrically/day) was combined with BPC 157 (in drinking water 0.16 μg or 0.16 ng/ml/12 ml/day/rat + 10 μg or 10 ng/kg intragastrically/day) till the sacrifice at day 4. In general, the controls could not heal cysteamine colitis and colon-colon anastomosis. BPC 157 induced an efficient healing of both at the same time[2].

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: ≥ 2.5 mg/mL (1.76 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: 2.5 mg/mL (1.76 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
