Alkali Scientific Erythromycin, 50 Grams

Erythromycin (50 g) is a broad-spectrum antibiotic that is particularly effective against Gram-positive bacteria and is commonly used to treat respiratory, skin, and soft tissue infections. As a macrolide antibiotic, erythromycin works by inhibiting bacterial protein synthesis through binding to the 50S ribosomal subunit. This prevents bacterial growth and replication, effectively treating infections caused by susceptible organisms. Erythromycin is used in both clinical and research settings, often prescribed as an alternative for patients allergic to penicillin. This 50 g quantity is ideal for laboratories conducting antimicrobial susceptibility testing and for clinical formulations requiring larger doses of the antibiotic.

Medchemexpress LLC Potassium oxonate | 2207-75-2 | 99.9% | 195.17 | 500 MG

Potassium oxonate (Potassium azaorotate) is a uricase inhibitor primarily used in research to inhibit the phosphorylation of 5-FU and for creating hyperuricemia animal models. This selective competitive inhibitor blocks hepatic uricase and is metabolized in the gastrointestinal tract, distributing primarily in small intestine cells where it is converted to cyanuric acid.

Inhibits the phosphorylation of 5-FU to 5-fluorouridine-5'-monophosphate.
Utilized in animal modeling to create hyperuricemia models.
Functions as a selective competitive uricase inhibitor.
Blocks the action of hepatic uricase.
After metabolism, primarily distributes within the cells of the small intestine.
Converted to cyanuric acid in the gastrointestinal tract through two pathways.
