Cell viability is not affected by treating guanidine hydrochloride (0.5-50 μM) at escalating concentrations for a full day [1]. UPR targets were not impacted by guanidine hydrochloride alone (0.5–50 μM, 24 h), neither at the mRNA or protein levels nor the phosphorylation state of eIF2a. Furthermore, neither GADD34 nor the constitutively active version of CReP are induced by guanabenz[1]. In newborn rat cardiomyocytes, guanidine hydrochloride alone (0.5–50 μM, 24 hours) does not cause endoplasmic reticulum stress [1].

| ln Vivo |
Brain cyst burden is consistently decreased by guanidine hydrochloride (5 mg/kg/day; intraperitoneally; for 3 weeks) [2]. In mice with latent Toxoplasma gondii infection, guanidine hydrochloride (5 mg/kg/d intraperitoneal injection, orally; 10 mg/kg/d gavage, for 3 weeks) can reverse hyperactivity [2]. In debuffered cats, guanidine hydrochloride (100 and 320 μg/kg and 1 mg/kg, intravenously given for 5 minutes at 40-minute intervals) lowers blood pressure, heart rate, and sympathetic outflow [3].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.34 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.34 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (9.34 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
