Antibiotiques

Neospiramycin I is a macrolide antibiotic with action on bacterial ribosomes to inhibit protein synthesis and is used for treating bacterial infections in research applications.

Tomopenem is a carbapenem antibiotic, which is a product of synthetic origin with broad-spectrum antibacterial properties. It acts by inhibiting the synthesis of bacterial cell walls through binding to penicillin-binding proteins, thereby disrupting the structural integrity of the cell wall and leading to bacterial cell lysis and death.

Tilmicosin is a macrolide antibiotic that is used in veterinary medicine. It is used to treat bovine respiratory disease and inhibits bacterial growth by binding to the 50S ribosomal subunit of the bacteria resulting in reduced protein synthesis.

Desfuroyl ceftiofur sodium is a veterinary cephalosporin antibiotic, which is derived from cephalosporin C, a beta-lactam antibiotic produced by the fungus Cephalosporium acremonium. Its mode of action involves the inhibition of bacterial cell wall synthesis by binding to and inactivating penicillin-binding proteins (PBPs). This prevents the cross-linking of peptidoglycan layers, leading to cell lysis and bacterial death, particularly effective against Gram-negative and some Gram-positive bacteria.

Validoxylamine A is an antibiotic, which is a secondary metabolite produced by certain strains of the Actinomyces species. It functions as a potent inhibitor of the enzyme glucose isomerase, which plays a crucial role in the isomerization of glucose to fructose, an important biochemical reaction in various microbial and plant systems.

Rifaximin is a rifamycin antibiotic with action on bacterial RNA polymerase to inhibit transcription and is used for treating travelers' diarrhea, irritable bowel syndrome, and hepatic encephalopathy.

Repromicin is a novel antibiotic, which is derived from a unique strain of actinobacteria. This organism is known for its ability to produce a wide range of bioactive compounds. Repromicin operates by inhibiting bacterial protein synthesis, a mode of action that involves binding to the bacterial ribosome and interfering with the translation process. This leads to an effective halt in bacterial growth and proliferation.

Amphotericin B is a macrocycle antibiotic with very potent antifungal effects and resistance very rarely occurs. Amphotericin B is a polyene antifungal that binds to fungal cell membrane, i.e., ergosterol disrupts the membrane permeability leading to leakage of intracellular components. It is often used as an alternative therapy for leishmaniasis and to treat severe mycoses including: systemic Candida, Cryptococcus, blastomycosis, and histoplasmosis.

Tylosin tartrate is a macrolide antibiotic with action on bacterial protein synthesis inhibition and is used for treating bacterial infections in livestock and poultry.

Herbicidin K is a naturally derived herbicide, known for its biological origin from microbial fermentation processes. It is primarily sourced from certain strains of Streptomyces, a genus of Gram-positive bacteria notable for their diverse secondary metabolites. The mode of action of Herbicidin K involves the inhibition of key enzymatic pathways within target plants, leading to the disruption of cellular functions and ultimately plant death. This selectivity is particularly effective against broadleaf weeds, providing a targeted approach to weed management.

Gentamicin C1a is an aminoglycoside antibiotic, which is a secondary metabolite derived from the bacterium Micromonospora. This antibiotic functions through a mode of action that involves binding to the 30S subunit of bacterial ribosomes. This binding disrupts protein synthesis by causing misreading of the mRNA, ultimately leading to inhibition of bacterial growth and cellular death.

Neomycin, one of the many oligosaccharide containing antibiotics, is an aminoglycoside antibiotic found in Streptomyces fradiae (Collins, 2006) with wide spectrum, active against Gram-negative Gram-positive bacteria. Neomycin is commony used as a selection marker in cloning, and is therefore used in growth media to select colonies with the neomycin resistance cassette integrated into their genome. Neomycin is a mixture of neomycin B (Framycetin) and its epimer Neomycin C, the latter component accounting for some 5–15% of the mixture.

Benethamine penicillin is a beta-lactam antibiotic, which is a semi-synthetic derivative of penicillin. It is sourced from the modification of naturally occurring penicillin compounds, typically produced through the fermentation of Penicillium mold cultures. Benethamine penicillin operates by inhibiting bacterial cell wall synthesis. It targets the penicillin-binding proteins within bacterial cell membranes, disrupting peptidoglycan cross-linking, which is essential for cell wall structural integrity. This leads to cell lysis and death in susceptible bacteria.

Anhydrooxytetracycline hydrochloride is a useful research chemical. Buy Anhydrooxytetracycline hydrochloride from Cymit Quimica for a variety of research applications.

Ceftaroline fosamil is an antibacterial agent used to treat various bacterial infections such as pneumonia. Ceftaroline fosamil binds to the ribosomal RNA of bacteria, preventing the formation of proteins necessary for cell division. Ceftaroline fosamil has been shown to be highly active against Mycobacterium tuberculosis, Mycobacterium avium complex, and fungi such as Candida species.
