semi-synthetic antibiotic

Methicillin sodium salt is the sodium salt form of methicillin, a semisynthetic beta-lactam penicillin antibiotic with beta-lactamase resistant activity.

Cefazaflur is a novel semi-synthetic cephalosporin derivative that can be used as an Antibiotic agent.

Cefdinir (FK-482) is a third-generation, semi-synthetic cephalosporin antibiotic effective against common bacterial infections of the ear, sinus, throat, and skin.

Cefepime Dihydrochloride Monohydrate (Cefepime HCl) is the hydrochloride salt of a semi-synthetic, beta-lactamase-resistant, fourth-generation cephalosporin antibiotic derived from an Acremonium fungal species with broad-spectrum bactericidal activity.

Ticarcillin disodium (Ticarpen) is the disodium salt form of ticarcillin, a broad-spectrum, semi-synthetic penicillin antibiotic with bactericidal and beta-lactamase resistant activity. Similar to carbenicillin in action, ticarcillin inactivates the penicillin-sensitive transpeptidase C-terminal domain by opening the lactam ring. This inactivation prevents the cross-linkage of peptidoglycan strands, thereby inhibiting the third and last stage of bacterial cell wall synthesis. This leads to incomplete bacterial cell wall synthesis and eventually causes cell lysis.

Clindamycin Phosphate is the phosphate salt form of clindamycin, a semi-synthetic, chlorinated broad-spectrum antibiotic produced by chemical modification of lincomycin. Clindamycin phosphate (Clindamycin 2-dihydrogen phosphate) is used in topical preparations.

Carbenicillin disodium (BRL-2064) is a broad-spectrum, semi-synthetic penicillin antibiotic with bactericidal and beta-lactamase resistant activity.

Roxithromycin (RU-28965) is a semi-synthetic macrolide antibiotic derived from erythromycin, exhibiting both antibacterial and anti-malarial properties.

Rifaximin is an orally administered, semi-synthetic, nonsystemic antibiotic derived from rifamycin SV with antibacterial activity. Rifaximin binds to the beta-subunit of bacterial DNA-dependent RNA polymerase, inhibiting bacterial RNA synthesis and bacterial cell growth.

Cefuroxime Sodium is the sodium salt form of cefuroxime and a semi-synthetic, broad-spectrum, beta-lactamase resistant, second-generation cephalosporin antibiotic with bactericidal activity. Cefuroxime sodium (Cefuroxime sodium salt) inhibits bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of the cell wall. Lack of cross-linking results in a reduction of cell wall stability and leads to cell lysis.

Cefditoren pivoxil (ME 1207) is a semi-synthetic, broad-spectrum, beta-lactamase resistant, third-generation cephalosporin antibiotic with bactericidal activity.

Azithromycin hydrate (CP-62993 dihydrate) is a semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.

Erythromycin estolate is a semi-synthetic derivative of erythromycin with good oral absorption and bioavailability tolerance. As a macrolide antibiotic, Erythromycin exerts its antibacterial action by inhibiting bacterial protein synthesis and is mainly used in studies for the treatment of respiratory, skin and soft tissue infections caused by susceptible bacteria. Erythromycin estolate may cause liver injury, including mild cholestatic hepatitis, jaundice, and paucity of bile ducts.

Cephalexin monohydrate (Cephalexin hydrate) is an orally available semi-synthetic cephalosporin antibiotic with significant antimicrobial activity that inhibits bacterial proliferation by targeting penicillin-binding proteins (PBPs).

Cefmetazole is a second-generation semi-synthetic β-lactam cephalosporin antibiotic with antimicrobial activity.

Cefotiam hydrochloride (SCE-963 hydrochloride) is the hydrochloride salt form of cefotiam, a third-generation, semi-synthetic, beta-lactam cephalosporin antibiotic with antibacterial activity. Cefotiam binds to penicillin-binding proteins (PBPs), transpeptidases that are responsible for crosslinking of peptidoglycan. By preventing crosslinking of peptidoglycan, cell wall integrity is lost and cell wall synthesis is halted.

Sulbactam (CP45899) is a semi-synthetic beta-lactamase inhibitor. The beta-lactam ring of sulbactam irreversibly binds to beta-lactamase at or near its active site, thereby blocking enzyme activity and preventing metabolism of other beta-lactam antibiotics by the enzyme. Combining this agent with a beta-lactamase susceptible antibiotic, such as penicillins or a cephalosporin, to treat infections caused by beta-lactamase producing organisms, results in a decreased turnover rate of the beta-lactamase sensitive antibiotic and enhances its antibacterial activity.

Cloxacillin Sodium, a chlorinated derivative of Oxacillin, is a semi-synthetic antibiotic. Cloxacillin is used for the treatment of infections caused by species of staphylococci which produce beta-lactamase.

Dihydrostreptomycin sulfate (Dihydrostreptomycin sesquisulfate) inhibits protein synthesis by binding to the 30S ribosomal subunit. Dihydrostreptomycin Sulfate is a semi-synthetic aminoglycoside antibiotic with bactericidal properties. This antibiotic is active against most gram-positive and gram-negative organisms and is used in the treatment of tuberculosis and tularemia.

Paldimycin A is a semi-synthetic antibiotic from Streptomyces paulus.

Paldimycin B is a semi-synthetic antibiotic.

Flopristin, a semi-synthetic antibiotic of the streptogramin A class, is a fluorinated derivative of pristinamycin IIB.

Laidlomycin phenylcarbamate is a semi-synthetic polyether antibiotic.

Pirlimycin Hydrochloride, a Clindamycin analog, is a semi-synthetic lincosaminide antibiotic.
