Pantoprazole Sodium (BY1023; SKF96022; Protonix) is an anti-ulcer drug that acts as a proton pump inhibitor (PPI) and is used for short-term treatment of erosion and ulceration of the esophagus caused by gastroesophageal reflux disease. Pantoprazole inhibits the activity of H+/K+-ATPase proton pumb in the parietal cells of gastric mucosa. This inhibition affects the acid secretion and thus, pantoprazole are used as drugs for the treatment of various acid-related disorders. Pantoprazole is activated slowly. The activated sulfonamide of pantoprazole binds to Cys813 and Cys822 of the pumb and inhibits acid secretion selectively.

| ln Vitro |
In EMT-6 and MCF7 cells, pantoprazole sodium (BY1023 sodium; 1–10,000 μM) raises endosomal pH in a concentration-dependent manner [1]. Pantoprazole sodium has the ability to prevent exosome release. Pantoprazole sodium prevents tumor cells (melanoma, adenocarcinoma, and lymphoma cell lines) from acidifying the extracellular media by blocking V-H+-ATPase activity [2].
|
| ln Vivo |
In MCF-7 xenografts, the combination of pantoprazole sodium (BY1023 sodium; 200 mg/kg; intraperitoneal injection; once weekly for 3 weeks) and doxorubicin considerably prolonged the tumor development delay [1]. Oral pantoprazole sodium (0.3–3 mg/kg) decreases mepizole-induced stimulated acid secretion in acute fistula rats and basal acid secretion in pyloric ligation rats in a dose-dependent manner [4].

| Enzyme Assay |
The action of the H+/K(+)-ATPase inhibitors pantoprazole and omeprazole was compared in different in vitro test systems. In gastric membrane vesicles under conditions shown to result in acidification of the vesicle interior, pantoprazole and omeprazole inhibited H+/K(+)-ATPase activity with IC50 values of 6.8 and 2.4 microM, respectively. When intravesicular acidification was reduced by inclusion of imidazole (5 mM), a membrane permeable weak base, the inhibitory action of omeprazole was partially lost (IC50 30 microM) and that of pantoprazole almost completely lost. After incubation for 40 min with pumping membrane vesicles, a half-maximal reduction in intravesicular H+ concentration occurred at pantoprazole and omeprazole concentrations of 1.1 and 0.6 microM, respectively. Again, when the intravesicular H+ concentration was reduced by inclusion of imidazole (2.5 mM), pantoprazole (20 and 60 microM) did not reduce the remaining intravesicular proton concentration, whereas omeprazole (10 and 30 microM) did. Both drugs inhibited, with similar potency, papain activity at pH 3.0 and inactivated the enzyme in a similar time-dependent manner; at pH 5.0 omeprazole (IC50 17 microM) was more potent than pantoprazole (IC50 37 microM) and enzyme inhibition was faster than with pantoprazole. These results indicate that pantoprazole is a potent inhibitor of H+/K(+)-ATPase under highly acidic conditions and that it is more stable than omeprazole at a slightly acidic pH such as pH 5.0[3].

| Cell Assay |
Murine EMT-6 and human MCF-7 cells were treated with pantoprazole to evaluate changes in endosomal pH using fluorescence spectroscopy, and uptake of doxorubicin using flow cytometry. Effects of pantoprazole on tissue penetration of doxorubicin were evaluated in multilayered cell cultures (MCC). Pantoprazole (>200 μmol/L) increased endosomal pH in cells, and also increased nuclear uptake of doxorubicin. Pretreatment with pantoprazole increased tissue penetration of doxorubicin in MCCs [1].

| Animal Protocol |
Animal/Disease Models: Mice bearing MCF-7 or A431 xenografts [1]
Doses: 200 mg/kg Route of Administration: IP; once weekly for 3 weeks; alone or in combination with doxorubicin (6 mg/kg iv) First 2 hour Experimental Results: The growth delay of MCF-7 xenografts with doxorubicin was even greater compared to the single dose combination. A single dose of doxorubicin Dramatically increased tumor growth delay. alone had no effect on growth delay. |

| Additional Infomation |
Pantoprazole sodium is an organic sodium salt. It has a role as an EC 3.6.3.10 (H(+)/K(+)-exchanging ATPase) inhibitor and an anti-ulcer drug. It contains a pantoprazole(1-).
Pantoprazole Sodium is the sodium salt form of a substituted benzimidazole with proton pump inhibitor activity. Pantoprazole is a lipophilic, weak base that crosses the parietal cell membrane and enters the acidic parietal cell canaliculus where it becomes protonated, producing the active metabolite sulfenamide, which forms an irreversible covalent bond with two sites of the H+/K+-ATPase enzyme located on the gastric parietal cell, thereby inhibiting both basal and stimulated gastric acid production. 2-pyridinylmethylsulfinylbenzimidazole proton pump inhibitor that is used in the treatment of GASTROESOPHAGEAL REFLUX and PEPTIC ULCER. Proton Pump Inhibitors: Compounds that inhibit H(+)-K(+)-EXCHANGING ATPASE. They are used as ANTI-ULCER AGENTS and sometimes in place of HISTAMINE H2 ANTAGONISTS for GASTROESOPHAGEAL REFLUX. Anti-Ulcer Agents: Various agents with different action mechanisms used to treat or ameliorate PEPTIC ULCER or irritation of the gastrointestinal tract. This has included ANTIBIOTICS to treat HELICOBACTER INFECTIONS; HISTAMINE H2 ANTAGONISTS to reduce GASTRIC ACID secretion; and ANTACIDS for symptomatic relief. |
