Composés et métabolites pharmaceutiques et vétérinaires

<p>Xanthosine 5'-monophosphate is produced from inosine monophosphate (IMP) through the catalytic action of inosine monophosphate dehydrogenase (IMPDH).</p>

<p>Pyrocatechol sulfate, a phenolic metabolite found in human plasma, is associated with the intake of specific foods such as berries and the state of the gut microbiome. It serves as a potential urinary biomarker for kidney function, dialysis clearance rates, whole grain consumption, and regular coffee intake. Additionally, in conjunction with other phenolic sulfates, pyrocatechol sulfate plays a role in regulating various biological functions, including those related to brain health and the rhythmic beating of cardiac cells.</p>

<p>Isoprostanes are produced by the non-enzymatic, free radical peroxidation of phospholipid-esterified arachidonic acid.</p>

<p>3β,7β-Dihydroxy-5-cholestenoic acid is a C27 acid whose levels are elevated in Niemann-Pick Type C and B diseases, leading to toxicity in ocular motor neurons. It is synthesized by the enzymatic action of hydroxysteroid 11-β dehydrogenase 1 from 3β-hydroxy-7-oxocholest-5-en-(25R)26-enoic acid (3βH,7O-CA).</p>

<p>13(R)-HODE, produced from linoleic acid, inhibits platelet aggregation (IC50=2.7μM) and is found in bovine endothelial cells.</p>

<p>Toladryl is a derivative of Diphenhydramine that can cross the blood-brain barrier and exhibits oral activity, with antihistamine and anticholinergic properties. Its anticholinergic effects are approximately a tenth of those seen with Diphenhydramine, yet it offers 2-4 times the protection against lethal doses of histamine in guinea pigs. The side effects of Toladryl are fewer and milder compared to Diphenhydramine; however, at higher doses, it may cause symptoms such as insomnia, agitation, and disorientation related to the central nervous system. Toladryl is utilized in the research of allergic diseases.</p>

<p>Calcium 2-hydroxypropanoate (pentahydrate) acts as an activator of the hydroxyl-carboxylic acid receptor 1 (HCAR1) and serves as an epigenetic regulator that induces lysine residue lactylation. This compound, a glycolysis end product, bridges the gap between glycolysis and oxidative phosphorylation and functions as a tumor metabolite with immunoprotective effects of lactate in antitumor immunity.</p>

<p>9(S)-HETE is an enantiomer of (±)9-HETE, not an enzymatic product, and doesn't promote cell adhesion like 12(S)-HETE. Identified by chiral HPLC.</p>

<p>Squalestatin 3 is an inhibitor of squalene synthase.</p>

<p>1,2-Dipentadecanoyl-rac-glycerol (DG(15:0/15:0/0:0)) is a compound referenced in studies examining the effect of insulin on the content of 1,2-diacylglycerol in rat hearts. Insulin is observed to increase the amount of 1,2-diacylglycerol containing specific fatty acid compositions in the heart, which may be linked to cardiac contractility.</p>

<p>D-2-Phosphoglyceric acid is a crucial metabolic intermediate known for its role in enhancing cellular energy metabolism and regulating biosynthesis. It plays a key role in both glycolysis and photosynthesis, which are essential for cellular energy supply. Additionally, D-2-Phosphoglyceric acid serves as a biomarker for monitoring metabolic states in various organisms.</p>

<p>7-Hydroxychlorpromazine, an active metabolite of Chlorpromazine, can reversibly counteract the suppression of regionally dense dopaminergic neurons induced by Amphetamine.</p>

<p>8-Oxo-dATP can be hydrolyzed to its monophosphate form by the oxidation of purine nucleoside triphosphate MTH1, preventing erroneous incorporation during DNA replication or transcription.</p>

<p>Miaosporone A: angucyclic quinone, cytotoxic to MCF-7, NCI-H187, Vero cells; anti-TB and anti-malaria with IC50 of 2.4 μM, 2.5 μM.</p>

<p>Homodestcardin: cyclic depsipeptide from T. roseum with immunosuppressant properties; inhibits mouse T cell proliferation.</p>

<p>Rostratin B, a cytotoxic disulfide, demonstrates in vitro cytotoxicity against human colon carcinoma (HCT-116), exhibiting an IC50 value of 1.9 μg/mL.</p>

<p>NADH-IN-2 (compound 8) is a Type II NADH dehydrogenase inhibitor.</p>

<p>Estradiol 3-glucuronide is an immunogen with antigenic properties. The antiserum induced in rabbits exhibits high affinity and specificity for Estradiol 3-glucuronide. This compound shows promise for use in research involving radioimmunoassay.</p>

<p>15:0 PG sodium serves as an activator for the Protein Kinase C family and is an anionic phospholipid located in the membranes of mitochondria and microsomes. It plays a crucial role in the composition of pulmonary surfactants, especially within the membrane of the pulmonary lamellar bodies.</p>

<p>Zaragozic acid C is an effective inhibitor of squalene synthase.</p>
