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.

    Heneicosane 629-94-7 ≥98.0%
    Heneicosane is a royal-specific pheromone of insects (such as subterranean termites) and is an identification signal for queens and kings in termites. Heneicosane mediates royal recognition and the maintenance of social division of labor by being sensed by worker ants and triggering vibrations and antennal behaviors. Heneicosane can exert anti-inflammatory, analgesic and antipyretic activities by inhibiting the release of inflammatory mediators (such as prostaglandins and cytokines). At the same time, Heneicosane can also inhibit the mycelial growth of aflatoxin-producing fungi and inhibit the production of aflatoxin. Heneicosane can be used in insect chemical ecology research to analyze the regulatory mechanism of termite social behavior, and is also a potential target for new anti-inflammatory drugs.
