Proglumide hemicalcium is a non-peptide and orally bioactive cholecystokinin (CCK)-A/B receptor blocker (antagonist). Proglumide hemicalcium selectively blocks the effects of CCK in the central nervous system. Proglumide hemicalcium has the ability to inhibit gastric secretion and protect the gastroduodenal mucosa, and also has antiepileptic and anti-oxidant effects.

Biological Activity


ln Vitro Proglumide at concentrations between 0.3 and 10 mM decreased CCK-stimulated amylase release in an in vitro investigation; at concentrations between 0 and 3 mM, proglumide had no effect on baseline amylase release. The dose-response curve of CCK produced by amylase moves to the right as the concentration of proglumide rises. Proglumide's inhibitory action is reversible. Proglumide also has a selective impact on CCK and related peptides [2]. With an IC50 of 6.5 mM, proglumide treatment of HT29 cells dramatically decreased the incorporation of [3H]-thymidine into HT29 cells in a dose-dependent manner. Proglumide increases apoptosis by up to 70% while decreasing the percentage of necrosis in a dose-dependent manner [3].
ln Vivo Proglumide (250-750 mg/kg; intraperitoneal injection; adult male Sprague-Dawley rats) is an effective treatment that greatly reduces brain oxidative stress, cognitive impairment, and seizure activity [1].
Animal Protocol Animal/Disease Models: Induction of status epilepticus (SE) in adult male Sprague Dawley rats (200-250 g; 2 months old) [1]
Doses: 250 mg/kg, 500 mg/kg, and 750 mg/kg
Route of Administration: Results of intraperitoneal (ip) injection: dose-dependent and significant increase in seizure and SE latency. Significant and dose-dependent attenuated Li-PC (SE)-induced increases in thiobarbituric acid (TBARS) and catalase (CAT), attenuated Li-Pc-induced decreases in SOD, and attenuated GSH and Depletion of glutathione-S transferase (GST). Hippocampus and striatum.

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)

Note: Please be aware that the above formulations are for reference only. 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.)

*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.
