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.

Research Products International Corp Chlortetracycline Hydrochloride, 5 Grams

Chlortetracycline Hydrochloride is a tetracycline antibiotic. Chlortetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. The interference disrupts the translation process and inhibits bacterial growth.

This antibiotic offers a broad spectrum of antibacterial activity against both Gram-positive and Gram-negative bacteria. It also forms complexes with calcium, magnesium, aluminum, and iron, leading to reduced absorption.

Additionally, it is useful to study bacterial susceptibility patterns or as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic.
