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.

    Sequoyitol 523-92-2 98.0%
    Sequoyitol (5-O-Methyl-myo-inositol) is an orally active hypoglycemic agent and antioxidant. Sequoyitol can be isolated from herbaceous plants. Sequoyitol downregulates the expression of NF-κB and TGF-β1, reduces ROS production and malondialdehyde levels, and enhances total antioxidant capacity. Sequoyitol activates the insulin signaling pathway, including the phosphorylation of IR, IRS1 and Akt. Sequoyitol increases serum insulin levels, inhibits hepatic glucose production, and promotes cellular glucose uptake. Sequoyitol antagonizes TNFα-induced inhibition of the insulin signaling pathway, and decreases blood urea nitrogen and serum creatinine levels. Sequoyitol elicits potential peaks in the chemosensors of adult and larval Atrophaneura alcinous, and acts as an oviposition stimulant for female Atrophaneura alcinous. Sequoyitol can be used in research related to type 2 diabetes, insulin resistance, hyperglycemia, impaired glucose tolerance and diabetic nephropathy.

    Pellitorine 18836-52-7 99.84%
    Pellitorine is a bioactive natural amide compound. Pellitorine can competitively antagonize the activation of TRPV1 by Capsaicin (HY-10448), thereby reducing pain signal transmission. Pellitorine improves cognitive dysfunction by upregulating the BDNF-ERK1/2-CREB and Nrf2-HO-1 pathways. Pellitorine exerts anti-inflammatory and anti-sepsis effects by inhibiting the release of high mobility group protein B1 (HMGB1) and the expression of RAGE/TLR4. Pellitorine exerts its antithrombotic effect by prolonging the clotting time, inhibiting the activity of clotting factors and thrombin. Pellitorine inhibits lipid peroxidation and resists ferroptosis by upregulating GPX4 and DHODH. Pellitorine kills Aedes aegypti mosquito larvae by inhibiting V-type H⁺-ATPase and aquaporin 4 (AaAQP4). Pellitorine exhibits anti-cancer activity (e.g., leukemia and breast cancer) and has inhibitory effects on certain bacteria.
