Abstract: The present invention relates to the use of the editing profile of PDE8A pre-mRNA as a specific bio marker of ADARs activities in evolved primate, particularly in Human tissues. The present invention also relates to an in vitro method for predicting in Human an alteration of the mechanism of the ADARs catalysed pre-mRNA editing of target genes, by analysing the PDE8A pre-mRNA editing profile in a peripheral tissue sample containing cells expressing said PDE8A pre-mRNA, such as blood sample. The present invention is also directed to an in vitro method for the screening of potential therapeutic compound and to predict and assess therapeutic efficacy and/or efficiency or to diagnose potential severe brain or peripheral drug side effects implementing said PDE8A pre-mRNA editing profile as specific biomarker.

Abstract: The present invention relates to in vitro methods for the determination of the potential toxicity of test compounds. The invention also comprises in vitro methods for the selection of therapeutical compounds useful for the treatment of pathology related to an alteration of the mechanism of the mRNA editing of ADAR dependent A to I mRNA editing of the serotonin 2C receptor (5HTR2C). Finally, the present invention is directed to the kits and tools for the implementation of these methods. The invention is of special utility in the pharmaceutical industry for analysis of the toxicity profile or the screening of compounds involved in drug development and/or in pharmaceutical compositions.

Abstract: The invention relates to a novel therapeutic use of 14,15-dihydro-20,21-dinoreburnamenin-14-ol for the treatment of serious depression in humans, particularly for the treatment of a patients resistant to conventional anti-depressant treatments and for treatment of sleep/waking cycle disorders.

Abstract: The invention concerns a method for analyzing nucleic acids using a small-size probe array comprising deoxyinostines (dI) instead of deoxyguanogines (dG). The invention also concerns such probe arrays and their use in methods for detecting and/or quantifying target oilgonucleotides present in DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecules in a sample, in particular mRNA editing rate of the serotonin 5-HT2C receptor (5-HT2C-R). The invention further concerns a biochip or a reactor in liquid medium comprising such probe arrays as well as their uses, in particular for detecting and/or identifying genetic polymorphisms or for determining an mRNA editing rate, whether it is that of a 5-HT2C-R mRNA or any other RNA capable of being edited.

Abstract: The invention relates to novel derivatives of 14,15-dihydro 20,21-dinoreburnamenin-14-ol, having formula (I) in which R represents a radical —AR? wherein A represents a heteroatom and R? represents a group selected from the group comprising linear or branched C1-C6 alkyl radicals, C2-C6 alkenyls, C2-C6 alkynyls, arylalkyls; esters comprising the formula —R1— CO—O—R2; amides comprising the formula —R3—CO—NZY, wherein Y and Z together can form a cycloalkyl radical or a heterocyclic radical, optionally substituted by one or more alkyl radicals; a radical selected from the group comprising alkyl radicals, alkenyls or alkynyls, substituted by at least one amine with formula —NZY; or one of the pharmaceutically-acceptable salts thereof, including the isomers, enantiomers and diastereoisomers thereof and mixtures thereof.
