Biological Activity
|
5-HT3 Receptor 3 μM (EC50) |
Phenylbiguanide (1-Phenylbiguanide) is a 5-HT3 receptor selective agonist with pEC50s of 5.57, 4.07, and 4.47 for r5-HT3A(b), h5-HT3A, m5-HT3A(b) , respectively[1]. The effect of Phenylbiguanide (1-Phenylbiguanide hydrochloride) in promoting the growth of the HT29 cell line is investigated. Phenylbiguanide causes a dose dependent proliferation of HT29 cells after 48 hours incubation. The maximum proliferation is at a 5HT concentration of 12.5 μM (P≤0.01). Phenylbiguanide significantly stimulates the growth of cells at concentrations of 3.125 μM (P≤0.05) and 6.25 μM (P≤0.01)[2].

Solvent & Solubility
DMSO : 40 mg/mL (187.20 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 4 mg/mL (18.72 mM); Clear solution
This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 4 mg/mL (18.72 mM); Clear solution
This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
HT29 cells are washed with Phosphate buffer saline (PBS) and harvested with a 0.5% trypsin solution at 50-60% confluency. Cells are then added to wells at a density of 104 cells/well in a 96-well plate to a final volume of 100 μL/well. After 24 hours of incubation at 37°C in a 5% CO2 atmosphere, the culture medium is replaced with 200 μL fresh culture medium containing 5HT hydrochloride, Phenylbiguanide hydrochloride at concentrations of: 3.125, 6.25, 12.5, 25, 50, and 100 µM . Cells cultured solely in media served as negative controls. After 48 hours of incubation at 37°C in a 5% CO2 atmosphere, the culture medium is removed and 8 µL MTT reagent (diluted in PBS at a concentration of 4 mg/mL) is added to 50 μL of fresh culture medium at a final concentration of 0.55 mg/mL. The optimum incubation period time is determined in a pilot study[2].

Mice[3]
Adult male specified pathogen free (SPF) BALB/c mice (28-33 g; n=10) are used throughout this study. All mice have free access to water and food in a light (12: 12 h light/ dark cycle, lights on at 0700 h) and temperature-controlled (21-23°C) environment. Mice are randomly assigned to two treatment groups, 1) intra-atrial injection of 0.9% saline (controls, n=5) or 2) intra-atrial injection of vehicle containing Phenylbiguanide (n=5). For the PBGinjected group, mice are injected with an effective dose of Phenylbiguanide (1-1.5 μg in 10-15 μL saline) . This is repeated five times in total with each injection separated by 8-10 min. For control mice, each mouse receives five saline injections (10-15 μL each), also at 8-10 min intervals[3].
