Alvelestat (AZD9668) is an orally active, selective inhibitor of neutrophil elastase. Alvelestat reduces elastase activity, myeloperoxidase release, neutrophil recruitment and activation, and calcium phosphate precipitation; promotes smooth muscle cell colonization and collagen deposition; and inhibits the formation of neutrophil extracellular traps (NETs) as well as NET-derived neutrophil elastase activity. Alvelestat restores endothelial dysfunction, regulates antioxidant factors, improves the expression of endothelial tight junctions, reduces vascular leakage, and accelerates wound healing. Alvelestat prevents pulmonary hemorrhage, matrix protein degradation, airspace enlargement, and small airway wall remodeling; and alleviates cigarette-induced inflammatory responses. Alvelestat inhibits the growth of abdominal aortic aneurysms exacerbated by Porphyromonas gingivalis. Alvelestat can be used in research related to chronic obstructive pulmonary disease, abdominal aortic aneurysm, radiation-induced skin injury, and bronchiectasis .

Homogentisic acid is an orally active, blood-brain barrier-permeable amyloidogenic compound that functions as both an amyloid component and a pigment precursor. Accumulation of homogentisic acid downregulates tight junction proteins (such as claudin-5, occludin, ZO-1) and impairs blood-brain barrier integrity. Homogentisic acid and its oxidation product benzoquinone acetic acid not only induce the aggregation and fibrosis of multiple proteins (such as 1-42, α-synuclein, SAA, Transthyretin (TTR), atrial natriuretic peptide), but also trigger oxidative stress, damage to the Wnt/β-catenin pathway, and neurotoxicity, leading to ochronosis pigment deposition and synaptic dysfunction. At specific concentrations, homogentisic acid exerts no cytotoxicity or genotoxicity on human peripheral blood lymphocytes, and even counteracts the genotoxicity induced by Irinotecan (HY-16562). Homogentisic acid serves as an important tool molecule for investigating the mechanisms of diseases including ochronosis, secondary amyloidosis, Alzheimer's disease, and colorectal cancer .

Humantenine is a highly toxic indole alkaloid from Gelsemium elegans (Gardn. & Champ.) Benth. that binds to RNA m6A modification regulatory proteins (ALKBH5, METTL). Humantenine stably binds via hydrogen bonding and hydrophobic interactions and disrupts the m6A methylation level of target genes, thereby impairing the expression of intestinal epithelial cell tight junction and cytoskeleton-related genes, causing intestinal barrier dysfunction and significant intestinal cytotoxicity. The intraperitoneal injection LD50 values of Humantenine are <1 mg/kg in mice, 1.2 mg/kg in male rats and 1.5 mg/kg in female rats, respectively. Species differences exist in the metabolism of Humantenine in human, porcine, goat and rat liver microsomes, and demethylation, dehydrogenation and oxidation occur in liver microsomes .
