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.

    Thonzonium bromide 553-08-2 99.86%
    Thonzonium bromide is an antibacterial agent that is structurally similar to Farnesol (HY-Y0248A). Thonzonium bromide is also a monocationic surface-active agent, which inhibits RANKL-induced osteoclast formation and bone resorption in vitro and prevents LPS-induced bone loss in vivo. Thonzonium bromide inhibits proton transport in a dose-dependent manner (EC50=69 μM).

    Nifurpirinol 13411-16-0 98.70%
    Nifurpirinol (P-7138) is a selective prosubstrate of bacterial nitroreductase (NTR). NTR catalyzes the reduction of nifurpirinol to generate cytotoxic metabolites that induce apoptosis in target cells. Nifurpirinol selectively ablates NTR-expressing cells such as pancreatic β cells, osteoblasts, dopaminergic neurons, and podocytes in transgenic zebrafish models. Nifurpirinol can be used in regeneration studies and disease modeling such as focal segmental glomerulosclerosis (FSGS).
