Antimicrobianos

Erythromycylamine is a semisynthetic antibiotic, which is derived from the parent compound erythromycin. This compound is sourced from the fermentation product of the bacterium *Saccharopolyspora erythraea*. Erythromycylamine acts by inhibiting bacterial protein synthesis, specifically targeting the 50S ribosomal subunit, which ultimately leads to the disruption of bacterial cell growth and replication.

Artefenomel is an antimalarial agent, which is a synthetic derivative originally based on artemisinin, primarily sourced from the Artemisia annua plant. It exhibits its mode of action by targeting and disrupting the Plasmodium parasite's life cycle within the human host. Specifically, artefenomel interferes with the parasite's ability to degrade hemoglobin, leading to the accumulation of toxic levels of heme, ultimately causing the parasite's death.

Hexazinone metabolite D is a derivative compound that results from the biotransformation of Hexazinone, which is a systemic herbicide. This metabolite originates from the breakdown processes mediated by biological or environmental factors in ecosystems where Hexazinone is applied. Its mode of action involves the inhibition of photosynthesis by targeting photosystem II, ultimately reducing the transfer of electrons, which leads to the disruption of energy production in susceptible plant species.

Clomeprop (free acid) is a selective herbicide, which is synthesized chemically to target grass species. Its mode of action involves the inhibition of the enzyme acetyl-CoA carboxylase, crucial for fatty acid synthesis. This interferes with lipid production, which is vital for plant growth and development.

Bisphenol A d14 is an isotopically labeled compound, which is a variant of Bisphenol A (BPA) where hydrogen atoms are partially replaced with deuterium isotopes. This compound is produced through chemical synthesis, ensuring that 14 of the hydrogen atoms in the BPA molecule are replaced by deuterium to create a stable form with a slightly higher atomic mass, facilitating advanced analytical studies.

Fenamiphos-sulfoxide d3 (S-methyl d3) is a deuterated, labeled pesticide intermediate, which is often utilized in advanced laboratory settings for precise analytical studies. This compound is synthesized as a stable isotope-labeled analog, enabling researchers to conduct sophisticated mass spectrometric analyses. Its mode of action involves serving as a reference or tracer in studies concerning the metabolism and degradation of fenamiphos, a well-known organophosphate pesticide.
