Apexbio Technology LLC PNPG 2492-87-7 1g
PNPG (2492-87-7) is a chromogenic substrate utilized for quantitative determination of -D-glucosidase activity It is designed to enable measurement of -D-glucosidase-mediated hydrolysis thereby facilitating assessment of glucosidase function and glucoside breakdown pathways PNPG exerts its biological activity primarily through enzymatic hydrolysis by -D-glucosidase producing para-nitrophenol which exhibits a yellow color detectable at 405 nm via spectrophotometry Based on these properties PNPG holds research potential in biochemical assays for measuring -D-glucosidase activity enzyme kinetics and studies of glucose metabolism in biomedical and pharmacological research

Apexbio Technology LLC Rebamipide 90098-04-7 1g
Rebamipide (CAS 90098-04-7) is a small molecule administered orally and recognized for its gastroprotective properties Its primary mechanism involves upregulation of cyclooxygenase-2 (COX-2) expression which leads to increased endogenous prostaglandin synthesis particularly prostaglandin E2 (PGE2) thereby enhancing gastric mucosal defense Studies also indicate that rebamipide can inhibit the proliferation of gastric cancer cells This compound is utilized in research investigating the mechanisms underlying gastric mucosal injury peptic ulcer disease gastritis and gastric cancer
