(Amoxicillin + omeprazole magnesium+ rifabutin) DR is a Small Molecule owned by RedHill Biopharma, and is involved in 6 clinical trials, which were completed.
Amoxicillin is a semisynthetic aminopenicillin antibiotic with bactericidal activity. Amoxicillin binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This interrupts bacterial cell wall synthesis and results in the weakening of the bacterial cell wall and causes cell lysis.
Omeprazole Magnesium is the magnesium salt form of a benzimidazole with selective and irreversible proton pump inhibitor activity. In the acidic compartment of parietal cells, omeprazole is protonated and converted into the active achiral sulfenamide; the active sulfenamide forms one or more covalent disulfide bonds with the proton pump hydrogen-potassium adenosine triphosphatase (H+/K+ ATPase), thereby inhibiting its activity and the parietal cell secretion of H+ ions into the gastric lumen, the final step in gastric acid production. H+/K+ ATPase is an integral membrane protein of the gastric parietal cell.
Rifabutin inhibits DNA-dependent RNA polymerase in susceptible strains of Escherichia coli and Bacillus subtilis but not in mammalian cells. In resistant strains of E. coli, rifabutin, like rifampin, did not inhibit this enzyme. It is not known whether rifabutin inhibits DNA-dependent RNA polymerase in Mycobacterium avium or in M. intracellulare which comprise M. avium complex (MAC).
Omeprazole is a proton pump inhibitor. Rifabutin is an antibiotic that inhibits DNA-dependent RNA polymerase activity in susceptible cells. Rifabutin acts via the inhibition of DNA-dependent RNA polymerase, leading to a suppression of RNA synthesis and cell death. Amoxicillin binds to and inactivates penicillin-binding protein (PBP) 1A located on the inner membrane of the bacterial cell wall and inhibits the third and last stage of bacterial cell wall synthesis. The proton pump inhibitors work by completely blocking the production of stomach acid. They do this by inhibiting a system in the stomach known as the proton pump. Proton pump inhibitors act by irreversibly blocking the hydrogen/potassium adenosine triphosphatase enzyme system of the gastric parietal cell.
The revenue for (Amoxicillin + omeprazole magnesium+ rifabutin) DR is expected to reach a total of $2.8bn through 2038. This change impacts the valuation of this asset and is an important factor to understand the current value of the drug in a clinical process.
