    Homogentisic acid

    		Amyloid-β Natriuretic Peptide Receptor (NPR) α-synuclein Transthyretin (TTR) Claudin Neurological Disease Metabolic Disease Cancer
    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 Aβ1-42, 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

    		Anaplastic lymphoma kinase (ALK) METTL3 Inflammation/Immunology
    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 .
