ProM - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | proglumide is the first discovered gastrin antagonist, and both progluric acid and benzotript are derivatives. proglumide, also a racemic compound named (±)-5-dipropylamino-4-benzoylamino-5-oxo-pentanoic acid, recorded in the Chinese Pharmacopoeia 2000 edition, Part Two, page 96, for the gastrin receptor antagonist, chemical structure and gastrin (G-17) and cholecystokinin (CCK) the terminal chemical structures of the two kinds of intestinal kinins are similar. Its functional group, Amide group, competes specifically with gastrin for gastrin receptors on parietal cells, thus it can significantly inhibit the secretion of gastric acid and pepsin caused by gastrin, but has no obvious effect on the secretion of gastric acid caused by histamine and vagus nerve stimulation. |
| indications | for gastric and duodenal ulcer, gastritis (such as Chronic superficial gastritis) and duodenal inflammation. |
| pharmacological action | This product is cholecystokinin receptor and gastrin receptor antagonist, its molecular structure and gastrin (G-17) and cholecystokinin (CCK) two kinds of intestinal kinin terminal molecular structure is similar, so the functional group amide group can be specific and G-17 competing with the Wall cell G-17 receptor, it can obviously inhibit the secretion of gastric acid and pepsin caused by G-17, increase the content of amino hexose in gastric mucosa, promote the synthesis of glycoprotein, protect gastric mucosa, so as to improve the symptoms of peptic ulcer and promote the healing of ulcer. The inhibitory effect of this product on gastric acid secretion caused by histamine and vagus nerve stimulation is not obvious, and the rebound phenomenon of gastric acid secretion does not occur in the treatment of peptic ulcer and gastritis, gastric acid secretion can still be at a normal level for half a year after termination of treatment. Because this product inhibits the role of gastric acid secretion than H2 receptor antagonists weak, clinical is no longer used alone for the treatment of ulcer disease, but recently its choleretic effect more attention. |
| drug interaction | 1. In combination with other anti-ulcer drugs (such as H2 receptor antagonists), it can enhance the effect of inhibiting gastric acid secretion and accelerate the healing of ulcer. 2. Combined with morphine, can enhance the analgesic effect of morphine and prolong the duration of its action. 3. This product can antagonize the effect of haloperidol to make the movement disorder worse, so the treatment of Huntington's Chorea can not be combined. |
| preparation | 1) preparation of N-benzoic acid glutamic acid a 1000 mL three-necked flask was charged with 50 g sodium gallate chlorate, 400 of water and appropriate amount of NaOH. Dissolve with stirring, adjust pH 7-8, add 37.2 mL of benzoyl chloride and 40% NaOH Dropwise below 2 ℃, control reaction temperature below 5 ℃, pH 8. Reaction at 5 deg C for 1 h, with 30% HCI adjusted to pH 1.5, cooling, crystallization, filtration, drying, N-benzoyl glutamic acid crude 71.8g,mp 134~140 deg C. 2) preparation of proglumide 60g(10.24 mot) of crude N-benzoylglutamic acid and 30g(0.22 mol) of acetic anhydride were taken. Add 75 mL of toluene to 500 mL three-mouth bottle, react at 85 ℃ for 30min, steam under normal pressure until no liquid drops out (toluene recovery and application), add 300 mL of ice water. Dipropylamine, 80mL, to be dissolved. React at 0 °c for 1 h, add acetic acid to adjust pH 4.5, stir, crystallize, dilute. The filter cake was added directly without drying. Distilled water, sodium carbonate and activated carbon were decolorized at 80 ℃ for 30min, filtered while hot, the filtrate was adjusted to pH 4.5, cooled, crystallized, filtered and dried to obtain 39 g of fine product, mp l48 ~ 151 ℃, the overall yield was 53.79%. |
| Use | This product is a gastrin receptor antagonist, which has the function of protecting gastric mucosa and promoting ulcer healing. Suitable for gastric and duodenal ulcer, gastritis, Stress ulcer, etc., the effective rate of 81-96%, the application of this product does not occur acid rebound increase, and the recurrence rate is low. gastrin receptor antagonist for gastric and duodenal ulcer disease |
| production method | N-benzoyl glutamic acid was obtained from glutamic acid and benzoyl chloride, then acetic anhydride is reacted to obtain N-benzoyl glutamic anhydride, and then aminated with dipropylamine to obtain proglumide. Based on glutamic acid, the overall yield was 26-30%. |
| category | toxic substances |
| toxicity grade | poisoning |
| Acute toxicity | intraperitoneal-rat LD50: 1420 mg/kg; Oral-mouse LD50: 8070 mg/kg |
| flammability hazard characteristics | flammability; Toxic NOx smoke from combustion |
| storage and transportation characteristics | ventilation and low temperature drying |
