Antimicrobials

<p>Inhibits DNA gyrase and topoisomerase IV</p>

STAADIUM™ PhosphoZide can be added as an enzyme-specific selective supplement to agar plates or as an enrichment agent to a broth culture. More details in the application notes document.</p>

<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>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>
