High Quality Cefalexin /Cephalexin Powder CAS 15686-71-2

What is Cephalexin ?

Cephalexin (cefalexin) is a cephalosporin antibiotic used to treat bacterial infections of the upper respiratory tract, the middle ear, the bones, the skin, and the reproductive and urinary systems. Cephalexin (cefalexin) works by interfering with the bacteria's cell wall formation. This weakens the cell wall, causing it to rupture, and kills the bacteria.

Function
The fourth generation cephalosporin. The antibacterial spectrum has been further expanded, and it has strong antibacterial activity against a variety of Gram-positive and negative bacteria, including Enterobacter, Pseudomonas aeruginosa, and other non-fermentable bacteria, Haemophilus, and Staphylococcus. It is used for various infections caused by sensitive bacteria, mainly for respiratory infections caused by maintenance infections such as Staphylococcus aureus, Enterobacter and Pseudomonas aeruginosa.

Application

The bacteriostatic mechanism of cephalexin is that by inhibiting the synthesis of bacterial cell wall, the cell contents expand to cell autolysis, thus achieving bactericidal effect.Cephalexin is a broad spectrum antibiotic.It has antibacterial effect on gram-positive and gram-negative bacteria, and its antibacterial ability is 20 times larger than penicillins, 10 times larger than sulfonamides and 5 times larger than quinolones.
Cephalexin is the first generation of cephalosporin, its antibacterial spectrum is basically the same as that of cephalosporin, but its antibacterial activity is weaker than the latter. In addition to Enterococcus and methicillin-resistant Staphylococcus aureus, most strains of Streptococcus pneumoniae, hemolytic streptococcus, and penicillinase producing or non-producing staphylococcus were sensitive to this product.

ECHEMI Editorial Reference

Cefalexin is a cephalosporin antibiotic.Target: AntibacterialCefalexin (INN, BAN) or cephalexin (USAN, AAN) is a first-generation cephalosporin antibiotic introduced in 1967 by Eli Lilly and Company. It is an orally administered agent with a similar antimicrobial spectrum to the intravenous agents cefalotin and cefazolin. It was first marketed as Keflex (Lilly), and is marketed under several other trade names. As of 2008, cefalexin was the most popular cephalosporin antibiotic in the Uni
Cephalexin is a cephalosporin antibiotic that is used to examine the impact of binding, expression, and inhibition of PBP3 as well as additional penicillin-binding proteins (PBPs) on the cell wall during bacterial mucopeptide synthesis. Cephalexin is used for the treatment of infection-causing bacteria that may induce ear, respiratory, urinary tract, and skin infections. Bacteria that are defenseless against Cephalexin may include Streptococcus pneumonia, Staphylococcus aureus, E. coli, and Haemophilus influenza. Cephalexin is also referred to as Keflex (brand name), and it does not relieve viral infections such as flu or colds.
Use of the ampicillin-type side chain conveys oral activity to cephalexin. Whereas it no longer has an activating side chain at C-3 and, as a consequence, is somewhat less potent, it does not undergo metabolic deactivation and, thus, maintains potency. It is rapidly and completely absorbed from the GI tract and has become quite popular. Somewhat puzzling is the fact that the use of the ampicillin side chain in the cephalosporins does not result in a comparable shift in antimicrobial spectrum. Cephalexin, like the other first-generation cephalosporins is active against many Gram-positive aerobic cocci but is limited against Gram-negative bacteria. It is a widely used drug, particularly against Gram-negative bacteria causing urinary tract infections, Gram-positive infections (Staphyl ococcus aureus, Streptococcus pneumoni ae and Streptococcus pyogenes) of soft tissues, pharyngitis, and minor wounds.
White cryst. powder
ChEBI: A semisynthetic first-generation cephalosporin antibiotic having methyl and beta-(2R)-2-amino-2-phenylacetamido groups at the 3- and 7- of the cephem skeleton, respectively. It is effective against both Gram-negative and G am-positive organisms, and is used for treatment of infections of the skin, respiratory tract and urinary tract.
