Derivati delle Purine e Pirimidine
Le purine hanno una struttura biciclica, composta da un anello a sei membri fuso con un anello a cinque membri, entrambi contenenti atomi di azoto in posizioni chiave. I derivati delle purine, come l’adenina e la guanina, sono essenziali per la formazione del DNA e dell’RNA. Questi composti trovano applicazione terapeutica nei trattamenti contro il cancro e le malattie virali, inibendo la replicazione cellulare. Le pirimidine, invece, hanno una struttura monociclica a sei membri con due atomi di azoto. I loro derivati, come la citosina, la timina e l’uracile, sono anch’essi componenti fondamentali del DNA e dell’RNA e vengono utilizzati in chemioterapia e nei trattamenti antivirali.
Presso CymitQuimica, offriamo derivati delle purine e pirimidine per la ricerca in biologia molecolare, genomica e sviluppo di terapie innovative.

CAS:<p>Tenofovir isoproxil monoester is a prodrug of Tenofovir, which is an antiviral drug. Tenofovir prevents the growth of HIV by interfering with the synthesis of viral DNA. The process development stage involves converting Tenofovir to its disoproxil monoester form, which has been shown to have greater antiviral activity than Tenofovir alone. This conversion process involves condensing one molecule of fumarate with two molecules of tenofovir, forming tenofovir disoproxil fumarate (TFD). TFD can be converted back to Tenofovir using hydrolysis and hydrogenation. Impurities in TFD include isopropyl tenofovir and unidentified impurities that are not present in the parent drug, tenofovir. Tenofovir Disoproxil Fumarate was also shown to be more potent than TFD and is undergoing clinical trials for</p>Formula:C14H22N5O7PPurezza:Min. 97 Area-%Colore e forma:White/Off-White SolidPeso molecolare:403.33 g/mol3-Amino-4-carbamoylpyrazole hemisulfate
