Infection is a pathophysiological process that involves the invasion and colonization of a living organism (host) by disease-causing infectious agents, the reaction of host tissues to these agents and the toxins they produce, and the transmission of infectious agents to other hosts. Common infectious agents include viruses, viroids, prions, bacteria, nematodes, arthropods, and other macroparasites such as tapeworms. Hosts can fight infections using their immune system. Mammals often engage both innate and adaptive immune systems to eliminate infectious agents or inhibit their growth and transmission. When infection occurs, anti-infective drugs can suppress the infection. Several broad types of anti-infective drugs exist, depending on the type of organism targeted; they include antibacterial (antibiotic), antiviral, antifungal and antiparasitic agents.

    Filibuvir 877130-28-4 ≥99.0%
    Filibuvir is an orally active, selective non-nucleoside inhibitor of the HCV nonstructural 5B protein (NS5B) RNA-dependent RNA polymerase (RdRp). Filibuvir binds noncovalently in the thumb II allosteric pocket of NS5B. Filibuvir inhibits genotype 1a and 1b replicons with EC50s of 59 nM for both isoforms, respectively. Filibuvir preferentially inhibits elongative RNA synthesis and potently decreases viral RNA accumulation.

    Eperezolid 165800-04-4
    Eperezolid (PNU-100592) is an orally active protein synthesis inhibitor that targets the bacterial 50S ribosomal subunit. Eperezolid competitively binds to a specific site on the ribosomal 50S subunit (overlapping with the binding sites of chloramphenicol (HY-B0239) and lincomycin (HY-117660)) to inhibit the translation initiation stage and exert antibacterial activity. Eperezolid can induce host cell autophagy to enhance the clearance of intracellular mycobacteria, and its MIC90 for Staphylococcus aureus and Enterococcus is 1-4 μg/mL. Eperezolid is mainly used for antibacterial research on infections with Gram-positive bacteria such as methicillin-resistant (HY-121544) Staphylococci and vancomycin-resistant (HY-B0671) Enterococci, as well as infections with intracellular bacteria such as Mycobacterium tuberculosis.
