Estudo indica que anticoagulante inibe replicação do vírus da covid

Pesquisa foi publicada no periódico Journal of Molecular Cell Biology

Um estudo conduzido por pesquisadores da Fundação Oswaldo Cruz (Fiocruz) indicou que o anticoagulante de uso oral Apixaban é eficaz para inibir a replicação do vírus Sars-CoV-2, causador da covid-19. Os resultados foram publicados no periódico científico Journal of Molecular Cell Biology e divulgados hoje (7) pela fundação.

Os pesquisadores constataram que uma enzima importantíssima no processo de replicação do coronavírus tem uma semelhança estrutural com uma substância envolvida no processo de coagulação, o que faz com que o anticoagulante interfira na multiplicação do vírus. A Fiocruz explica que esse tipo de medicamento já era recomendado para prevenir níveis altos de Dímero D, que é o produto final da cascata de coagulação e está relacionado diretamente à covid-19 severa.

“O uso de anticoagulantes ajuda a prevenir a covid severa, e tínhamos a preocupação de descobrir se havia mecanismos adicionais para esse benefício clínico”, explicou à Agência Fiocruz de Notícias um dos autores do estudo, o pesquisador Thiago Moreno Souza, do Centro de Desenvolvimento Tecnológico em Saúde (CDTS/Fiocruz).

“Esse trabalho mostra que sim e descreve como este mecanismo funciona, provando que essa atividade antiviral também pode estar contribuindo, em alguma magnitude, para o benefício clínico que esses pacientes têm”, disse.

Os cientistas envolvidos no estudo recomendam que a estrutura química do anticoagulante Apixaban seja avaliada de forma mais profunda para que se possa entender com precisão como funciona essa interferência na replicação viral. Compreender esse processo com mais precisão pode servir de ponto de partida para, no futuro, desenvolver antivirais específicos contra a covid-19.

  1. LUGAS ist das zentrale System der GGL, das monatliche Einzahlungslimits von 1000 €
    pro Spieler anbieterübergreifend in allen deutschen Casinos überwacht.
    Wichtig dabei ist, dass Sie sich der Risiken bewusst sind und nur bei
    lizenzierten und vertrauenswürdigen Casinos aktiv werden,
    wenn Sie mit hohen Einsätzen spielen. Wenn deutsche Spieler ohne Einsatzlimit im Casino Plinko spielen oder
    andere Games zocken, dann müssen Sie evtl.

    Es ist wichtig, dass Sie sich der Risiken ausländischer Casinos
    bewusst sind und immer verantwortungsvoll spielen. Bei
    ausreichender Bonität können Sie Ihr monatliches Einzahlungslimit über LUGAS erhöhen und im geschützten Rahmen mit höheren Beträgen spielen. Allerdings werden diese
    Anbieter nicht nach denselben deutschen Standards überwacht.
    Nach erfolgreicher Bonitätsprüfung können Sie anschließend
    mit höheren Beträgen spielen.
    Das iPhone 17 Pro oder das Samsung Galaxy S25 Ultra mit ihren leistungsstarken Chips und atemberaubenden 120Hz-Displays bieten eine Konsolen-ähnliche Erfahrung in der Hand.
    Während traditionelle Online-Casinos oft Einsatzlimits von einigen Tausend Euro pro Spin oder Runde haben, brechen diese Elite-Plattformen alle Schranken nieder.

    Dennoch setzen manche Anbieter freiwillig Grenzen oder bieten Tools zur Selbstkontrolle.

  3. If you’re looking for real cards, real dealers, and
    high-energy tables, this is a standout pick. It’s not the largest library of
    games on our list, but Casinonic manages to pack a punch where it counts.

    With over 7,000 games, Skycrown has a library
    that’s just hard to beat.
    First and foremost, gambling sites accepting Australian players let you play in AUD,
    which means no conversion fees to pay. When playing casino games online, you can easily get carried away.
    Doing so lets you get familiar with the rules and
    gameplay and prepare for real money play. Then, follow our step-by-step guide
    to start playing with real money. The critical
    condition is a wagering requirement, indicating how much you must stake in real money to turn your bonus
    into real cash. Some players act hastily, choosing a casino site based on its welcome bonus.
