Description：Cimetidine (SKF-92334) is an orally active and inverse histamine H2 receptor antagonist with a Ki of 0.6 μM. Cimetidine is a gastric acid reducer, and can be used for duodenal and gastric ulcers research. Cimetidine has anti-cancer and anti-inflammatory activity.

In Vitro：Cimetidine (SKF-92334), a partial agonist for H2R, has a pharmacological profile different from ranitidine and famotidine, possibly contributing to its antitumor activity on gastrointestinal cancers [1]. Cimetidine had no effect on the uptake and cytotoxicity of cisplatin in ovarian cancer cells with high OCT2 mRNA levels (IGROV-1 cells)[3]. Cimetidine showed no effect on proliferation, survival, migration and invasion of 3LL cells. Cimetidine reversed MDSC-mediated T-cell suppression, and improved IFN-γ production[4]. Cimetidine-mediated down-regulation of NCAM involved suppression of the nuclear translocation of NF-kappaB, a transcriptional activator of NCAM gene expression[5].

In Vivo：Cimetidine (SKF-92334) reduceS CD11b(+)Gr-1(+) myeloid derived-suppressive cell (MDSC) accumulation in spleen, blood and tumor tissue of tumor-bearing mice[4]. Cimetidine exerts a beneficial effect on periodontal disease in rats, decreasing the RANKL/OPG ratio in gingival connective tissue and reducing alveolar bone resorption[6].

IC50 & Target：H2 Receptor Histamine Receptor 0.6 μM (Ki)
