Antimicrobianos

(+)-Oxanthromicin is a natural compound classified as a polyketide antibiotic, which is derived from certain strains of soil-dwelling actinomycetes. These microorganisms are known to produce a variety of biologically active secondary metabolites. The mode of action of (+)-Oxanthromicin involves the inhibition of specific bacterial enzymes, disrupting essential processes within the microbial cells. This interference can lead to growth inhibition or cell death, showcasing its potential as a therapeutic agent.

Cefteram is a third-generation cephalosporin antibiotic, which is synthesized through chemical processes starting from cephalosporin C, a compound derived from the fungus Acremonium. As a cephalosporin, it functions by inhibiting bacterial cell wall synthesis. This is achieved through the binding to penicillin-binding proteins (PBPs), which are critical in the formation of the bacterial cell wall. By disrupting this process, Cefteram leads to the lysis and death of the bacteria.

Bombinin-like peptide (blp-1) is an antimicrobial peptide, which is derived from the skin secretion of certain amphibians, specifically the *Bombina* species of frogs. This peptide functions by disrupting microbial cell membranes, leading to cell lysis and death. Its ability to compromise the integrity of the cell membrane makes it effective against a range of pathogenic microorganisms, including bacteria and fungi.

Streptidine dihydrochloride is a biochemical compound, specifically a derivative of streptomycin, which is obtained through chemical modification of the aminoglycoside antibiotic streptomycin. It is composed of streptidine, a constituent sugar derivative, that is integral to the structure of streptomycin, rendered as a hydrochloride salt to enhance solubility and stability.

Rifamdin is an antibiotic, which is a chemical substance derived from the source compound rifampicin. Its mode of action involves the inhibition of bacterial DNA-dependent RNA polymerase, which effectively suppresses bacterial RNA synthesis, leading to cell death. This mechanism primarily targets Mycobacterium tuberculosis, the causative agent of tuberculosis.

7,10-Dihydroxy-8(E)-octadecenoic acid is a hydroxylated fatty acid, which is derived from the microbial transformation of oleic acid by certain bacterial species, particularly Pseudomonas aeruginosa. This compound features a unique structure characterized by its dihydroxy modifications and a cis double bond. The compound's mode of action involves modulating bacterial growth and metabolic pathways, possessing antimicrobial properties that result from its ability to interfere with cell membrane integrity and function.

Kanamycin sulfate is an aminoglycoside antibiotic, derived from the bacterium *Streptomyces kanamyceticus*. Its mode of action involves binding to the 30S subunit of the bacterial ribosome, thereby inhibiting protein synthesis and ultimately leading to bacterial cell death. This mechanism is particularly effective against gram-negative bacteria and certain gram-positive bacteria.

7,8-Didemethyl-8-hydroxy-5-deazariboflavin is a cofactor often referred to as a deazaflavin. It is a derivative of riboflavin and is primarily sourced from methanogenic archaea. These microorganisms are found in anaerobic environments and play a crucial role in the process of methanogenesis.

3'-N,N-Di(desmethyl)-3'-N-formyl azithromycin is a semisynthetic macrolide antibiotic derivative, which is synthesized through chemical modification of azithromycin. Azithromycin is originally derived from erythromycin, which is produced by the bacterium Saccharopolyspora erythraea. The modifications in this derivative result in enhanced specificity and altered pharmacokinetic properties compared to the parent compound.
