Lansoprazole (AG 1749) is an orally active proton pump inhibitor which prevents the stomach from producing acid. Lansoprazole (AG 1749) is a potent brain penetrant neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor).

Famotidine (MK-208) is an orally active and highly selective histamine H2 receptor antagonist. It inhibits gastric acid secretion by blocking the Gs signaling pathway, and regulates intracellular cAMP and ERK pathways. Famotidine inhibits TLR3-mediated inflammatory pathways, and reduces the expression of various inflammatory mediators and interferon-related genes. Famotidine scavenges DPPH and nitric oxide free radicals, alleviates oxidative stress damage in gastric tissue, inhibits proMMP-9, improves vascular endothelial permeability, and restores the normal physiological functions of neutrophils and eosinophils. Famotidine crosses intestinal epithelial cells via facilitated diffusion and passive diffusion, blocks paracellular cation transport, and increases intestinal transepithelial electrical resistance. Famotidine reduces serum levels of transaminases and alkaline phosphatase, exerts analgesic effects and gastric protective effects simultaneously. Famotidine can be used in studies related to COVID-19, liver injury and acute gastric ulcer.

Zinc sulphate is an orally active inhibitor of tyrosinase and glutathione reductase. Zinc sulphate enhances the activity of dopachrome tautomerase. Zinc sulphate delays anagen-related eumelanin production, induces hair hypopigmentation in mice, and accelerates wound healing. Zinc sulphate can be used in research related to benign gastric ulcers. Zinc sulphate can be used in research related to rheumatoid arthritis.

Vonoprazan Fumarate (TAK-438), a proton pump inhibitor (PPI), is a potent and orally active potassium-competitive acid blocker (P-CAB), with antisecretory activity. Vonoprazan Fumarate inhibits H⁺,K⁺-ATPase activity in porcine gastric microsomes with an IC₅₀ of 19 nM at pH 6.5. Vonoprazan Fumarate is developed for the research of acid-related diseases, such as gastroesophageal reflux disease and peptic ulcer disease.

Sodium bicarbonate, for cell culture (Sodium hydrogen carbonate for cell culture; Soda bicarbonate for cell culture) is an inorganic salt that is neutral to slightly alkaline and easily decomposes when exposed to moisture in the air. Sodium bicarbonate, for cell culture can maintain the pH of the culture medium, thereby affecting the expression of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) production in macrophages and reversing the acidosis of the tumor microenvironment. Sodium bicarbonate is widely used in the fields of food, medicine, cosmetics, etc. Its main uses include buffers, flavoring agents, disinfectants, pharmaceuticals, and proton gradient regulators. Sodium bicarbonate is also commonly used as an antacid to inhibit gastrointestinal diseases, neutralize gastric acid, and reduce gastric discomfort.

Ac4GlcNAz (N-azidoacetylglucosamine-tetraacylated) is an azido-containing fully acetylated N-acetylglucosamine analog, a metabolic glycan marker, and also an inducer of S-glycosylation. Ac4GlcNAz can be taken up by bacteria, processed via endogenous carbohydrate biosynthesis pathways, and integrated into glycans by replacing natural monosaccharides. Under alkali promotion, Ac4GlcNAz undergoes β-elimination to form α,β-unsaturated aldehydes, which then bind to cysteine residues via Michael addition. Ac4GlcNAz can be integrated into glycoproteins. Ac4GlcNAz is applicable to research related to Helicobacter pylori infection.

Esomeprazole sodium ((S)-Omeprazole sodium) is a potent and orally active proton pump inhibitor. Esomeprazole reduces acid secretion through inhibition of the H⁺, K⁺-ATPase in gastric parietal cells.
