| Hazard Information | Back Directory | [Description]
25-hydroxy Cholesterol is an oxysterol.1 It is formed from cholesterol by cholesterol-25-hydroxylase, and its production can be induced by inflammation or infection.2 25-hydroxy Cholesterol suppresses endogenous cholesterol synthesis by binding to insulin-induced gene (INSIG) proteins and preventing sterol regulatory element binding proteins (SREBPs) from being transported to the Golgi. It inhibits IgA class switching induced by LPS and various cytokines in B cells (IC50 = ~50 nM).3 25-hydroxy Cholesterol inhibits replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Vero cells (EC50 = 3.675 μM) and reduces increases in viral protein production in infected Vero cells when used prior to infection.4 It reduces viral RNA loads in the lung and trachea in a mouse model of SARS-CoV-2 infection when administered at a dose of 100 mg/kg per day. Serum levels of 25-hydroxy cholesterol are increased in mice expressing human angiotensin-converting enzyme 2 (hACE2), the functional receptor for SARS-CoV-2, in a model of SARS-CoV-2 infection and in a patient with COVID-19, the primarily respiratory disease caused by SARS-CoV-2. | [Chemical Properties]

An oxygenated derivative of Cholesterol (C432501); an oxysterol. An inhibitor of human immunodeficiency virus replication in vitro. It induces apoptosis in human monocytic cell lines as well as induc
ing apoptosis in CEM cells associated with negative regulation of c-Myc. | [Definition]
ChEBI: 25-hydroxycholesterol is an oxysterol and a 25-hydroxy steroid. It has a role as a human metabolite. It is functionally related to a cholesterol. | [General Description]
25-hydroxy-cholesterol is a side chain substituted oxysterol. Avanti′s unique sterol reverses cataracts in mice. Gestwicki′s team ...... settled on compound 29, a steroid found naturally in the bloodstream but not in the lens, which has no blood supply. Mice with age-related and hereditary cataracts received drops in the right eye, whereas the left eye went untreated. After just a few weeks, the treated eye was visibly clearer, says Gestwicki, who conducted the work while at the University of Michigan. Cataract severity is measured on a scale of zero to four, with four being the worst case. On average, mice in the study had about a one-grade improvement in cataract severity after 4 weeks of treatment. Science DOI: 10.1126/science.aad7400 It has been recently shown that activation of a macrophage toll-like receptor (TLR) by microbial antigens induces synthesis of 25-hydroxycholesterol, and that this oxysterol potently suppresses IgA production. | [Biochem/physiol Actions]
25-Hydroxycholesterol is a side-chain oxysterol that reportedly triggers activation of a number of cholesterol molecules. This triggers their movement from cell membrane to the endoplasmic reticulum (ER). 25-Hydroxycholesterol affects the immune system and has a key role in the pathogenesis of atherosclerosis. | [storage]

25-Hydroxycholesterol forms colourless needles from MeOH [Schwartz Tetrahedron Lett 22 4655 1981]. The 3acetoxy derivative has m 142-142.8o (from Me2CO) and [] D -40.4o (c 2, CHCl3). The 3,25-diacetoxy derivative has m 119-120.5o (from MeOH) and [] 25D -35.5o (CHCl3). [Dauben & Bradlow J Am Chem Soc 72 4248 1950, Ryer et al.
