Zusammenfassung:Abstract Compounds are provided for the delivery of nucleic acids as well as conjugates of these compounds with nucleic acids, in particular siRNAs. A conjugate is prepared by a process comprising conjugating an antisense oligonucleotide with a compound of formula (III): 41-0 6 "cr.? - j (; 0 _10 0..40 0 0 (m) The oligonucleotide is a single-stranded non-naturally occurring nucleic acid comprising a non-naturally occurring nucleotide, which is a locked nucleic acid (LNA). A process for conjugation is also described, in which the conjugating is canied out using N-Hydroxy-succinimide (NHS) chemistry. Date Recue/Date Received 2021-03-23 Il est décrit des composés abstrait servant à livrer des acides nucléiques ainsi que des conjugués de ces composés et dacides nucléiques, particulièrement de petits ARNi. Un conjugué est préparé au moyen dun procédé qui comprend la conjugaison dun oligonucléotide antisens et dun composé de la formule (III) : 41- 0 6 cr.? - j (; 0 _10 0..40 0 0 (m). Loligonucléotide est un acide nucléique monocaténaire dorigine non naturelle qui comprend un nucléotide dorigine non naturelle, soit un acide nucléique bloqué. Il est également décrit un procédé de conjugaison dans lequel la conjugaison est effectuée au moyen de la chimie du N-hydroxysuccinimide (NHS). Date Recue/Date Received 2021-03-23
