Famotidine (MK-208) is an orally active and highly selective histamine H2 receptor antagonist. It inhibits gastric acid secretion by blocking the Gs signaling pathway, and regulates intracellular cAMP and ERK pathways. Famotidine inhibits TLR3-mediated inflammatory pathways, and reduces the expression of various inflammatory mediators and interferon-related genes. Famotidine scavenges DPPH and nitric oxide free radicals, alleviates oxidative stress damage in gastric tissue, inhibits proMMP-9, improves vascular endothelial permeability, and restores the normal physiological functions of neutrophils and eosinophils. Famotidine crosses intestinal epithelial cells via facilitated diffusion and passive diffusion, blocks paracellular cation transport, and increases intestinal transepithelial electrical resistance. Famotidine reduces serum levels of transaminases and alkaline phosphatase, exerts analgesic effects and gastric protective effects simultaneously. Famotidine can be used in studies related to COVID-19, liver injury and acute gastric ulcer .

Inulin is an orally active prebiotic targeting the intestinal microbiota, selectively promoting the proliferation and activity of beneficial bacteria such as bifidobacteria and lactic acid bacteria, and playing a role in regulating the intestinal microecology. The functions of Inulin include: Fermentation by probiotics in the colon to produce short-chain fatty acids (such as butyrate and propionate), lowering the intestinal pH and inhibiting the overgrowth of harmful bacteria; Enhancing the intestinal barrier function and reducing endotoxin translocation; Directly scavenging free radicals (such as superoxide free radicals, hydroxyl free radicals) and activating antioxidant enzymes (SOD, CAT) to reduce oxidative stress. Inulin can also be used in the study of intestinal diseases (constipation, IBD), metabolic syndrome (diabetes, obesity) and liver damage by regulating glucose and lipid metabolism (such as reducing triglycerides, improving insulin sensitivity) and immune response (enhancing NK cell activity, inhibiting inflammatory factors)[1][2][3][4].

ALR2-IN-9 is a potent ALR2 inhibitor (IC50 = 21.8 nM) with excellent antioxidant activity (EC50 for DPPH radical scavenging = 2.8 μM). ALR2-IN-9 interacts directly with Reactive Oxygen Species (ROS)/Reactive Nitrogen Species (RNS) and interrupts the free radical chain reactions, and as an endogenous enzymatic antioxidant regulator, which regulates enzyme functions of CAT and SOD. ALR2-IN-9 regulates PI3K/Akt/Nrf2 pathway to attenuate hyperglycemia-mediated mitochondrial superoxide overproduction in vitro, and ameliorates CuSO4- and H2O2-induced oxidative stress in vivo. ALR2-IN-9 prolongs lifespan of C. elegans via the regulation of stress response genes such as PMK-1. ALR2-IN-9 is a promising anti-aging drug candidate. ALR2-IN-9 can be used for diabetic complication research .
