Biological Activity
| ln Vitro | Cimetidine (SKF-92334) hydrochloride is a partial agonist of H2R. Its anticancer effect against gastrointestinal malignancies may be attributed to its distinct pharmacological features from those of ranitidine and famotidine [1]. Cimetidine hydrochloride has no effect on cisplatin absorption and cytotoxicity in IGROV-1 cells, which are high OCT2 mRNA ovarian cancer cells [3]. 3LL cell migration, invasion, survival, and proliferation were all unaffected by cimetidine hydrochloride. Cimetidine hydrochloride stimulates the production of IFN-γ and reverses T cell inhibition mediated by MDSC [4]. The inhibition of NF-kappaB's nuclear translocation, a transcriptional activator of NCAM gene expression, is a necessary step in the imimetidine-mediated downregulation of NCAM [5]. |
| ln Vivo | Cimetidine hydrochloride (SKF-92334) can diminish the increase of CD11b(+)Gr-1(+) myeloid-derived suppressor cells (MDSC) in the spleen, blood and tumor tissue of tumor-bearing mice [4]. Cimetidine hydrochloride has a positive effect on periodontal disease in rats, lowering the RANKL/OPG ratio in gingival connective tissue and reducing alveolar bone resorption [6]. |

| Additional Infomation |
A histamine congener, it competitively inhibits HISTAMINE binding to HISTAMINE H2 RECEPTORS. Cimetidine has a range of pharmacological actions. It inhibits GASTRIC ACID secretion, as well as PEPSIN and GASTRIN output. See also: Cimetidine (has active moiety). |
Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
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 (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *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). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently. (Please use freshly prepared in vivo formulations for optimal results.) |
