Zinc Pyrithione is an antifungal and antibacterial agent disrupting membrane transport by blocking the proton pump.Target: Proton PumpZinc pyrithione is considered as a coordination complex of zinc. The pyrithione ligands, which are formally monoanions, are chelated to Zn 2+ via oxygen and sulfur centers. In the crystalline state, zinc pyrithione exists as a centrosymmetric dimer, where each zinc is bonded to two sulfur and three oxygen centers. In solution, however, the dimers dissociate via scission of one Zn-O bond. Zinc pyrithione, which is a dimer but is probably biologically active as a monomer, induces plasma membrane depolarization with half-maximal effect (K1/2) of about 0.3 mM [1]. Zinc pyrithione is an unusual synthetic potentiator that potently activates both heterologous and native M channels by inducing channel opening at the resting potential [2]. Zinc pyrithione rapidly accumulated in the tissues of the exposed mussels, proportionately to both exposure concentration and time. Even though the 7-d median lethal concentration (LC50) = 8.27 μM established here appears high with respect to reported ZnPT environmental concentrations, the results indicate that this biocide could represent a threat for marine organisms in coastal environments and that further investigations on its biological effects at sublethal doses are needed [3].
Lansoprazole Sulfide D4 is a deuterium labeled Lansoprazole Sulfide. Lansoprazole Sulfide is an active metabolite of the proton pump inhibitor Lansoprazole. Lansoprazole Sulfide is an orally active anti-TB (Mycobacterium tuberculosis) agent with IC50 values of 0.59 µM intracellularly and 0.46 µM in broth[1].
Vonoprazan hydrochloride, a proton pump inhibitor (PPI), is a potent and orally active potassium-competitive acid blocker (P-CAB), with antisecretory activity. Vonoprazan hydrochloride inhibits H+,K+-ATPase activity in porcine gastric microsomes with an IC50 of 19 nM at pH 6.5. Vonoprazan hydrochloride is developed for the research of acid-related diseases, such as gastroesophageal reflux disease and peptic ulcer disease. Vonoprazan hydrochloride can be used for eradication of Helicobacter pylori[1][2][3].
Abscisic acid-d6 (ABA-d6) is deuterium labeled Abscisic acid. Abscisic acid inhibits proton pump (H+-ATPase)[1].
Zastaprazan is a proton pump inhibitor (WO2018008929). Zastaprazan can be used for the research of gastrointestinal inflammatory diseases or gastric acid-related diseases[1].
Picoprazole is a specific inhibitor of H+/K+-ATPase with IC50 of 3.1±0.4 μM.
AZD0865 inhibits gastric H+,K+-ATPase by K+-competitive binding. (IC50: 1.0 ± 0.2 μM)It is a acid-suppressing agents with rapid onset of action and potent acid inhibition. In vitro: AZD0865 can inhibit the final step in acid secretion. AZD0865 reduced porcine renal Na+,K+-ATPase activity by 9 ± 2%, demonstrating a high selectivity for H+,K+-ATPase.In vivo: The reference for animal administration is 0.5-1.0 mg/kg. The greater degree of acid suppression with the 75-mg dose of AZD0865 would translate to a healing rate of 89% at 4 weeks.
Revaprazan (SB 641257) is a reversible proton pump inhibitor with significant anti-inflammatory effects. Revaprazan can be used for chronic gastric inflammation research[1][2].
