Mupirocin 98% white powder 12650-69-0 Senwayer

Mupirocin(BRL-4910A) is an antibiotic of the monoxycarbolic acid class; effective against Gram-positive bacteria, including MRSA.
Solid
Mupirocin is an alpha,beta-unsaturated ester resulting from the formal condensation of the alcoholic hydroxy group of 9-hydroxynonanoic acid with the carboxy group of (2E)-4-[(2S)-tetrahydro-2H-pyran-2-yl]-3-methylbut-2-enoic acid in which the tetrahydropyranyl ring is substituted at positions 3 and 4 by hydroxy groups and at position 5 by a {(2S,3S)-3-[(2S,3S)-3-hydroxybutan-2-yl]oxiran-2-yl}methyl group. Originally isolated from the Gram-negative bacterium Pseudomonas fluorescens, it is used as a topical antibiotic for the treatment of Gram-positive bacterial infections. It has a role as a bacterial metabolite, an antibacterial drug and a protein synthesis inhibitor. It is a monocarboxylic acid, a member of oxanes, an epoxide, a secondary alcohol, a triol and an alpha,beta-unsaturated carboxylic ester. It is a conjugate acid of a mupirocin(1-).|Mupirocin, formerly termed pseudomonic acid A, is a novel antibacterial agent with a unique chemical structure and mode of action apart from other antibiotic agents. Produced by fermentation using the organism Pseudomonas fluorescens, mupirocin is a naturally-occurring antibiotic that displays a broad-specturm activity against many gram-positive bacteria and certain gram-negative bacteria in vitro. It primarily works by inhibiting bacterial protein synthesis. Due to its unique mode of action of inhibiting the activity of bacterial isoleucyl-tRNA synthetase, mupirocin does not demonstrate cross-resistance with other classes of antimicrobial agents, giving it a therapeutic advantage. It is available in topical formulations only due to extensive systemic metabolism and is used in the treatment of impetigo caused by Staphylococcus aureus and Streptococcus pyogenes and traumatic skin lesions due to secondary skin infections caused by S. aureus and S. pyogenes. There is also some clinical evidence that suggests the potential role of mupirocin in eradicating nasal carriage of Staphylococci when administered intranasally. Mupirocin is commonly marketed under the brand name Bactroban.|Mupirocin is a RNA Synthetase Inhibitor Antibacterial. The mechanism of action of mupirocin is as a RNA Synthetase Inhibitor.|Mupirocin is a natural crotonic acid derivative extracted from Pseudomonas fluorescens. Mupirocin inhibits bacterial protein synthesis by specific reversible binding to bacterial isoleucyl tRNA synthase. With excellent activity against gram-positive staphylococci and streptococci, it is primarily used for treatment of primary and secondary skin disorders, nasal infections, and wound healing. (NCI04)|A topically used antibiotic from a strain of Pseudomonas fluorescens. It has shown excellent activity against gram-positive staphylococci and streptococci. The antibiotic is used primarily for the treatment of primary and secondary skin disorders, nasal infections, and wound healing.
