:(±)-Warfarina
Descrizione:
(±)-Warfarina è un anticoagulante sintetico comunemente usato nella prevenzione e nel trattamento dei disturbi tromboembolici. Funziona inibendo la vitamina K epossido reduttasi, che è essenziale per la sintesi dei fattori di coagulazione dipendenti dalla vitamina K nel fegato. Questo composto esiste come una miscela racemica di due enantiomeri, R e S, con l'enantiomero S che è significativamente più potente come anticoagulante. La warfarina è caratterizzata dalla sua relativamente bassa solubilità in acqua, ma è solubile in solventi organici, il che facilita la sua formulazione in varie preparazioni farmaceutiche. La sostanza ha una formula molecolare di C19H16O4 e un peso molecolare di circa 308,34 g/mol. La sua farmacocinetica prevede somministrazione orale, con un inizio d'azione ritardato a causa del tempo necessario affinché i fattori di coagulazione esistenti diminuiscano. La warfarina è soggetta a una significativa variabilità interindividuale nel dosaggio a causa di fattori come polimorfismi genetici, assunzione dietetica di vitamina K e interazioni con altri farmaci, richiedendo un attento monitoraggio dei parametri di coagulazione durante la terapia.

CAS:<p>Warfarin is a coumarin that is used as an oral anticoagulant. It has been in use for over 50 years and is still the most widely prescribed drug for the prevention of thromboembolic disease. Warfarin inhibits the synthesis of vitamin K-dependent clotting factors II, VII, IX, and X. This inhibition leads to a prolonged prothrombin time and increased bleeding time. Warfarin also prevents blood from clotting by inhibiting platelet aggregation. The molecular weight of Warfarin is 798 Da, which corresponds to its molecular weight heparin (MWH) binding site.<br>Warfarin has a narrow therapeutic window and requires careful monitoring by measuring prothrombin time in order to prevent adverse effects such as excessive bleeding or blood clots. Warfarin also interacts with many drugs, including aspirin and non-steroidal anti-inflammatory drugs like ibuprofen, which can lead to increased risk of bleeding</p>Formula:C19H16O4Purezza:Min. 95%Colore e forma:White Slightly Brown Clear LiquidPeso molecolare:308.33 g/molWarfarin
CAS:<p>Warfarin (Coumafene) is a vitamin K antagonist, and it works by blocking the action of vitamin K, which is necessary for the synthesis of clotting factors in the liver. Warfarin blocks the action of vitamin K by inhibiting the enzyme gamma-glutamyl carboxylase, which is responsible for the carboxylation of glutamate residues in the clotting factors. This prevents the production of functional clotting factors, leading to an anticoagulant effect.</p>Formula:C19H16O4Purezza:99.35%Colore e forma:SolidPeso molecolare:308.3279
