Antimicrobials

<p>Broad-spectrum antibiotic; bacterial cell wall biogenesis inhibitor</p>

<p>Versalide is a synthetic musk compound with action as a fragrance ingredient and is used for adding scent to perfumes and personal care products.</p>

<p>Chlorpropham-4-hydroxy-o-sulfonic acid is a herbicide metabolite with action on plant growth regulation and is used for environmental and agricultural research.</p>

<p>Raltegravir is an antiretroviral agent used for the treatment of HIV infections in conjunction with other antiretrovirals. It inhibits the activity of HIV-1 integrase, which impedes the insertion of HIV-1 DNA into the host cell genome. Raltegravir also inhibits resistant mutants of HIV-1 that are associated with disease activity and progression.</p>

<p>Impurity of Micafungin; anti-fungal</p>

<p>Filociclovir is a novel antiviral agent, which is synthesized from small-molecule pharmaceutical compounds. It functions primarily by inhibiting viral DNA polymerase, thereby halting viral replication within infected host cells. This mechanism of action is particularly effective against certain herpesviruses, as it targets the polymerase enzyme that is critical for viral DNA synthesis and proliferation.</p>

<p>Nystatin is an antifungal compound, which is produced by the bacterium *Streptomyces noursei*. It functions by binding to ergosterol, a crucial component of fungal cell membranes, creating pores that lead to increased membrane permeability. This disruption results in the leakage of essential cellular components, ultimately causing cell death.</p>

<p>A thiopeptide antibiotic produced by the bacterium Streptomyces actuosus. In addition, nosiheptide inhibits bacterial protein biosynthesis by acting during the elongation of the protein.</p>

<p>Posaconazole is a triazole antifungal agent that inhibits the 14-alpha demethylase enzyme. This drug prevents the formation of fungal cell walls thus leading to fungal cell lysis. Posaconazole is shown to inflict its inhibitory activity against common pathogenic fungus such as Candida and Aspergillus species in severely immunocompromised patients.</p>

<p>Anti-viral; HIV protease inhibitor</p>

<p>Cephalothin sodium is a first-generation cephalosporin antibiotic with action on bacterial cell wall synthesis and is used for treating bacterial infections such as respiratory tract infections and skin infections.</p>

<p>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.</p>

<p>Dasabuvir is a non-nucleoside NS5B polymerase inhibitor with action on hepatitis C virus RNA replication and is used for treating hepatitis C in combination therapies.</p>

<p>Meropenem trihydrate has broad spectrum activity against Gram-positive and Gram-negative bacteria, as well as, some mycoplasma species. It inhibits cell wall synthesis by binding to bacterial penicillin-binding proteins (PBP), which impairs cell wall integrity, induces the formation of reactive oxygen species, and inhibits macromolecular synthesis in bacteria. It can be used to prevent bacterial growth after being exposed to meropenem through fluorescence imaging of human blood plasma. Meropenem trihydrate research studies showed a reduction of the allergen levels in patients with respiratory allergies or asthma, specifically dust mites, cockroaches, animal dander, pollen grains, etc. by inhibit allergen-induced sensitization of mast cells.</p>

<p>Remdesivir (R)-isomer is a nucleoside analog antiviral with action on RNA-dependent RNA polymerase to inhibit viral replication and is used for treating COVID-19 and other RNA virus infections.</p>

<p>Orbifloxacin is a fluoroquinolone antibiotic with action on bacterial DNA gyrase and topoisomerase IV and is used for treating bacterial infections in veterinary medicine.</p>

<p>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.</p>

<p>Inducer of DNA strand breaks; glycopeptide antibiotic, anti-neoplastic</p>

<p>Aminoglycoside antibiotic; inhibits protein synthesis by inducing miscoding</p>

<p>Gatifloxacin is an antibiotic, which is a synthetic fluoroquinolone with broad-spectrum antibacterial activity. Its source lies in its chemical synthesis, designed to inhibit bacterial enzymes necessary for DNA replication. The mode of action involves the inhibition of bacterial DNA gyrase and topoisomerase IV, which are critical enzymes for bacterial DNA replication, transcription, and repair. This dual inhibitory mechanism disrupts bacterial cell division and growth, leading to the eventual eradication of susceptible bacterial strains.</p>
