Derivados de Purinas e Pirimidinas
As purinas possuem uma estrutura bicíclica, formada por um anel de seis membros fundido a um anel de cinco membros, ambos contendo átomos de nitrogênio em posições-chave. Os derivados das purinas, como a adenina e a guanina, são essenciais para a formação do DNA e RNA. Estes compostos possuem aplicações terapêuticas no tratamento do câncer e de doenças virais, pois inibem a replicação celular. As pirimidinas, por outro lado, possuem uma estrutura monocíclica de seis membros com dois átomos de nitrogênio. Seus derivados, como citosina, timina e uracila, também são componentes essenciais do DNA e RNA e são utilizados na quimioterapia e em tratamentos antivirais.
Na CymitQuimica, oferecemos derivados de purinas e pirimidinas para pesquisa em biologia molecular, genômica e desenvolvimento de terapias inovadoras.

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>Fórmula:C14H22N5O7PPureza:Min. 97 Area-%Cor e Forma:White/Off-White SolidPeso molecular:403.33 g/mol4-[[(2,4-Diamino-6-pteridinyl)methyl]methylamino]benzoic acid
