Antimicrobiens

<p>Posaconazole is an antifungal agent that inhibits the 14-alpha demethylase enzyme which is responsible for the synthesis of the fungal cell wall component, ergosterol. This demethylase enzyme synthesizes ergosterol through converting lanosterol to ergosterol. Therefore Posaconazole prevents the formation of fungal cell walls with the appropriate membrane permeability thus leading to fungal cell lysis. Posaconazole can be used as an antifungal drug to treat opportunistic fungal infections in immunocompromised individuals such as HIV patients. Moreover it is shown to inflict its inhibitory activity against common pathogenic fungus such as Candida and Aspergillus species but also Mucorales and some Fusarium species, which are less common.</p>

<p>2-Methyl-4-isothiazolin-3-one HCl , also known as MIT hydrochloride is often used as a preservative in personal care products and other industrial applications. The product has shown to act as an antimicrobial and antifungal agent.</p>

<p>Inhibitor of protein synthesis; steroid antibiotic</p>

<p>Erythromycin thiocyanate is a macrolide antibiotic derivative with action on bacterial protein synthesis inhibition and is used for research and pharmaceutical applications.</p>

<p>Enrofloxacin is a rapidly bactericidal antibiotic, that inhibits bacterial growth by binding to the 50S ribosomal subunit and blocking protein synthesis, thereby preventing the bacteria from making new proteins. Enrofloxacin also has strong activity against gram-positive bacteria, including Clostridium perfringens which is an anaerobic bacterium that causes food-borne illness. This antibiotic is used for the treatment of acute bacterial infections in humans, such as, skin or soft tissue infections, urinary tract infections (UTIs) and septicemia (bloodstream infection). Enrofloxacin has shown excellent bioavailability with high serum protein binding capacity. Additionally, it has good efficacy against clinical isolates of Escherichia coli and Klebsiella pneumoniae. Enrofloxacin can be used effective in treatments for Pseudomonas aeruginosa and Enterobacter species.</p>

<p>Pefloxacin mesylate is a fluoroquinolone antibiotic with action on bacterial DNA gyrase and topoisomerase IV and is used for treating bacterial infections, including urinary and respiratory tract infections.</p>

<p>Tenofovir diphosphate triethylamine (mixture of diastereomers) is an antiviral compound, which is a synthetic chemical product derived from the parent compound, tenofovir. This formulation includes a mixture of diastereomers to enhance its solubility and bioavailability. The compound primarily functions as a nucleotide reverse transcriptase inhibitor (NRTI). It targets viral reverse transcriptase enzymes, inhibiting DNA synthesis and subsequent viral replication by causing premature chain termination.</p>

<p>Cefuroxime is a second-generation cephalosporin antibiotic with action on bacterial cell wall synthesis and is used for treating respiratory tract infections, urinary tract infections, and Lyme disease.</p>

<p>Streptomycin sulfate is an antibiotic that inhibits the growth of bacteria by binding to the ribosomal subunit and interfering with protein synthesis. It is used in culture media for the production of human antibodies as well as in drug therapy for methicillin-resistant staphylococcus. Streptomycin sulfate has a high specific activity and low sensitivity, but it also has a low solubility in water. The active form of streptomycin sulfate is streptomycin A, which is produced by the addition of a phenyl ring to neomycin sulfate. In plant roots, streptomycin sulfate inhibits cyanogenic glycosides from being hydrolyzed into hydrogen cyanide (HCN) and benzaldehyde.</p>

<p>Flubendazole is a benzimidazole anthelmintic with action on microtubule formation in parasites and is used for treating intestinal worms in humans and animals.</p>

<p>Antibiotic of fluoroquinolone class; DNA replication inhibitor</p>

<p>Ceftriaxone is a broad-spectrum cephalosporin antibiotic that is used for the treatment of bacterial infections in different locations such as the skin, soft tissue and respiratory tract. This drug works by inhibiting mucopeptide synthesis in the bacterial cell wall. As a result, bacteria will produce defective cell walls leading to cell death.</p>

<p>Pirazinecarboxamide (Pyrazinamide) is an antitubercular agent with action on Mycobacterium tuberculosis by disrupting membrane energetics and is used for treating tuberculosis in combination with other drugs.</p>

<p>Cefadroxil monohydrate is a hydrated form of cefadroxil with similar action and applications as cefadroxil.</p>

<p>Nucleoside analog with antiviral activity against zoonotic feline infectious peritonitis virus (FIPV) and severe acute respiratory syndrome (SARS) virus from Coronaviridae family. The compound is a pro-drug and undergoes intracellular phosphorylation resulting in the active triphosphate metabolite. The triphosphorylated GS 441524 analog competes with natural nucleoside triphosphates and interferes with viral RNA synthesis. In previous studies it was tested in vitro as well as in experimental animals and showed good safety profile.</p>

<p>Darunavir is a HIV-1 protease inhibitor used orally in the treatment of patients with multi-drug resistant HIV-1 infection (Ghosh, 2007). It has also been shown to be effective against other infectious diseases such as hepatitis C virus and SARS coronavirus. Metabolized by cytochrome P450 3A (CYP3A) isoenzymes, darunavir is often administered together with ritonavir that prolongs its bioavaiability, giving a terminal elimination half-life (t1/2) of 15 hours (Back, 2008). The effect of darunavir on natural compounds such as matrix proteins and toll-like receptor activity has also been studied via high performance liquid chromatography (HPLC) experiments.</p>

<p>Cefozopran hydrochloride is a fourth-generation cephalosporin antibiotic with action on bacterial cell wall synthesis and is used for treating severe bacterial infections, including those caused by resistant strains.</p>

<p>Dibekacin sulfate is an aminoglycoside antibiotic with action on bacterial protein synthesis inhibition and is used for treating severe gram-negative bacterial infections.</p>

<p>Anthracycline is a class of chemotherapy drugs, which are anthraquinone antibiotics derived from the bacterial genus Streptomyces. They exert their therapeutic effects primarily through intercalation into DNA, disrupting the function of enzymes such as topoisomerase II, thus preventing the transcription and replication processes in rapidly dividing cancer cells. Furthermore, they generate free radicals, leading to oxidative stress and subsequent cell damage. These mechanisms collectively result in apoptosis of malignant cells. Anthracyclines are utilized extensively in oncology for the treatment of various malignancies, including leukemias, lymphomas, breast cancer, and sarcomas. The efficacy of anthracyclines in inhibiting tumor growth must be balanced against their cardiotoxic potential, which is a significant consideration in their clinical use. This dual nature makes them both pivotal and challenging in chemotherapy regimens, necessitating careful management and monitoring throughout treatment.</p>

<p>Abacavir is an antiviral nucleoside reverse transcriptase inhibitor that is used for the treatment of HIV. This drug inhibits the activity of HIV-1 reverse transcriptase (RT) both by competing with dGTP and by its incorporation into viral DNA.</p>
