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 Aβ_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.

VUT-MK142 is a cardiomyogenic small molecule. VUT-MK142 upregulates the expression of the myocardial marker ANF and other myocardial markers. VUT-MK142 promotes the development of cardiovascular progenitor cells into beating cardiomyocytes, and facilitates the differentiation of cardiac anterior mesoderm into cardiomyocytes. VUT-MK142 can be used in the research of heart failure.
