Guanoclor (CAS#: 5001-32-1) binds to non-adrenergic sites in pig kidney membranes (IC₅₀ for inhibition of [³H]idazoxan binding = 10 ± 5 nM).[1]
Guanoclor (CAS#: 5001-32-1) inhibits Na⁺/H⁺ exchange activity with an IC₅₀ of 1 μM.[1] |

| ln Vitro |
Guanoclor (CAS#: 5001-32-1) potently inhibited specific [³H]idazoxan binding to pig kidney membranes in a concentration-dependent manner, with an IC₅₀ value of 10 ± 5 nM (n=3). It was among the most potent imidazolidines tested, slightly more potent than guanabenz (IC₅₀ = 18 ± 5 nM) and guanoxan (IC₅₀ = 20 ± 3 nM).[1]
Guanoclor (CAS#: 5001-32-1) inhibited Na⁺/H⁺ exchange activity with an IC₅₀ of 1 μM, as previously reported (Frelin et al., 1986).[1] |
| Enzyme Assay |
For [³H]idazoxan binding experiments, crude pig kidney membranes were incubated with 2 nM [³H]idazoxan in a buffer consisting of 2 mM EGTA, 1 mM MgCl₂, and 50 mM Tris-Cl at pH 7.4. The incubation was carried out for 45 minutes at 20°C. Bound and free ligand were separated by rapid vacuum filtration through GF/C filters, and the bound radioactivity was determined by liquid scintillation counting. Non-specific binding was determined in the presence of 10 μM tolazoline or 10 μM guanoxan. In competition experiments, various concentrations of unlabeled compounds (including Guanoclor (CAS#: 5001-32-1)) were tested in duplicate at least 10 concentrations. IC₅₀ values are defined as the concentration required to inhibit specific [³H]idazoxan binding by 50%.[1]

| Additional Infomation |
Guanoclor is a dichlorobenzene.
See also: Guanoclor sulfate (note moved to). Guanoclor (CAS#: 5001-32-1) is an imidazolidine derivative recognized for its antihypertensive properties, traditionally believed to act as a central α₂-adrenoceptor agonist. This study demonstrates that it also binds with high affinity (IC₅₀ = 10 nM) to a novel class of non-adrenergic binding sites in pig kidney membranes. These sites are distinct from α₂-adrenoceptors (yohimbine binding sites), clonidine-preferring sites, the Na⁺/H⁺ exchanger, and the epithelial Na⁺ channel, as [³H]idazoxan binding was not displaced by adrenergic compounds (epinephrine, prazosin, phenylephrine, yohimbine) and amiloride derivatives showed different potency orders.[1] |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*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.
