Cellobiose is a disaccharide with the formula (C 6 H 7 (OH) 4 O) 2 O. It is classified as a reducing sugar - any sugar that possesses the ability or function of a reducing agent. The chemical structure of cellobiose is derived from the condensation of a pair of β-glucose molecules forming a β(1→4) bond. It can be hydrolyzed to glucose ...
Rifampicin is the INN and BAN, while rifampin is the USAN. Rifampicin may be abbreviated R, RMP, RA, RF, or RIF (US). [citation needed] Rifampicin is also known as rifaldazine, [63] [64] rofact, and rifampin in the United States, also as rifamycin SV. [65]
Rifampin rapidly kills fast-dividing bacilli strains as well as "persisters" cells, which remain biologically inactive for long periods of time that allow them to evade antibiotic activity. [7] In addition, rifabutin and rifapentine have both been used against tuberculosis acquired in HIV-positive patients.
Rifapentine in pregnant women has not been studied, but animal reproduction studies have resulted in fetal harm and were teratogenic. If rifapentine or rifampin are used in late pregnancy, coagulation should be monitored due to a possible increased risk of maternal postpartum hemorrhage and infant bleeding. [2]
In enzymology a cellobiose epimerase (EC 5.1.3.11) is an enzyme that catalyzes the chemical reaction cellobiose ⇌ {\displaystyle \rightleftharpoons } D-glucosyl-D-mannose Hence, this enzyme has one substrate , cellobiose , and one product , D-glucosyl-D-mannose .
In a bacterium without the proper mutation(s) in rpoB rifampicin binds to a site near the fork in the β subunit and prevents the polymerase from transcribing more than two or three base pairs of any RNA sequence and stopping production of proteins within the cell.
Traditional Vietnamese medicine (Y học Cổ truyền Việt Nam), also known as Southern Herbology (Thuốc Nam) is a traditional medicine practiced by Vietnamese people. It is influenced by traditional Chinese medicine.
Scientists at the Italian drug company Achifar discovered rifabutin in 1975. (Eventually Archifar became part of Farmitalia Carlo Erba, a unit of the conglomerate Montedison which was subsequently bought by Pharmacia) This company's Adria Laboratories subsidiary filed for Food and Drug Administration (FDA) approval of rifabutin under the brand name Mycobutin in the early 1990s and the drug ...
