Title (EN) COMPOSITIONS AND METHODS FOR ENHANCED SENSITIVITY AND SPECIFICITY OF NUCLEIC ACID SYNTHESIS
(FR) COMPOSITIONS ET METHODES PERMETTANT D'OBTENIR UNE SENSIBILITE ET UNE SPECIFICITE AMELIOREES DE LA SYNTHESE D'ACIDE NUCLEIQUE
Abstract:
(EN) The present invention relates to nucleic acid inhibitors, compositions and method for enhancing synthesis of nucleic acid molecules. In a preferred aspect, the invention relates to inhibition or control of nucleic acid synthesis, sequencing or amplification. Specifically, the present invention discloses nucleic acids having affinity for polypeptides with polymerase activity for use in such synthesis, amplification or sequencing reactions. The nucleic acid inhibitors are capable of inhibiting nonspecific nucleic acid synthesis under certain conditions (e.g., at ambient temperatures). Thus, in a preferred aspect, the invention relates to 'hot start' synthesis of nucleic acid molecules. Accordingly, the invention prevents, reduces or substantially reduces nonspecific nucleic acid synthesis. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the nucleic acid inhibitors or compositions of the invention. The invention also relates to using the inhibitors of the invention to prevent viral replication or treat viral infections in a subject. Thus, the invention relates to therapeutic methods and pharmaceutical compositions using the inhibitors of the invention. The invention thus may be used for in vivo and in vitro inhibition of nucleic acid synthesis and /or inhibition of polymerase acitivity.
(FR) L'invention concerne des inhibiteurs d'acide nucléique, des compositions et une méthode permettant d'améliorer la synthèse de molécules d'acide nucléique. Dans un mode de réalisation préféré, l'invention concerne l'inhibition ou la régulation de la synthèse, du séquençage ou de l'amplification d'acide nucléique. D'une manière spécifique, l'invention concerne des acides nucléiques présentant une affinité avec des polypeptides à activité polymérase destinés à être utilisés dans ces réactions de synthèse, d'amplification ou de séquençage. Ces inhibiteurs d'acide nucléique sont capables d'inhiber la synthèse d'acide nucléique non spécifique dans certaines conditions (par exemple, à des températures ambiantes). Dans un mode de réalisation préféré, l'invention concerne la synthèse de molécules d'acide nucléique selon la technique du 'hot start'. Ainsi, l'invention permet d'empêcher, de réduire ou de réduire sensiblement la synthèse d'acide nucléique non spécifique. L'invention concerne également des trousses permettant d'effectuer la synthèse, l'amplification, la transcription inverse ou le séquençage de molécules d'acide nucléique comprenant un ou plusieurs des inhibiteurs d'acide nucléique ou des compositions selon l'invention. L'invention concerne en outre l'utilisation des inhibiteurs selon l'invention pour prévenir une réplication virale ou pour traiter des infections virales chez un patient. L'invention concerne en outre des méthodes thérapeutiques et des compositions pharmaceutiques utilisant les inhibiteurs selon l'invention. L'invention peut ainsi servir à inhiber in vivo et in vitro la synthèse d'acide nucléique et/ou l'inhibition de l'activité polymérase.
