Iterative, preferably computer based iterative processes for generating synthetic compounds with desired physical, chemical and/or bioactive properties, i.e., active compounds, are provided. During iterations of the processes, a target nucleic acid sequence is provided or selected, and a library of candidate nucleobase sequences is generated in silico according to defined criteria. A "virtual" oligonucleotide chemistry is chosen and a library of virtual oligonucleotide compounds having the selected nucleobase sequences is generated. These virtual compounds are reviewed and compounds predicted to have particular properties are selected. The selected compounds are robotically synthesized and are preferably robotically assayed for a desired physical, chemical or biological activity. Active compounds are thus generated and, at the same time, preferred sequences and regions of the target nucleic acid that are amenable to oligonucleotide or sequence-based modulation are identified.

L'invention concerne des processus itératifs, de préférence informatiques, permettant de former des composés synthétiques présentant les propriétés physiques, chimiques, et/ou bioactives souhaitées, en d'autres termes des composés actifs. Pendant les itérations de ces processus, on prend ou on choisit une séquence d'acide nucléique cible, une banque de séquences de nucléobases candidates étant par ailleurs formée in silico selon des critères définis. On choisit ensuite une chimie oligonucléotidique ?virtuelle? et on forme une banque de composés oligonucléotidiques virtuels présentant les séquences de nucléobases choisies. Puis on passe en revue ces composés virtuels de manière à pouvoir choisir les composés susceptibles de présenter certaines propriétés, les composés choisis étant ensuite synthétisés par des organes automatisés afin de détecter l'activité physique, chimique, ou biologique souhaitée. On forme ainsi des composés actifs tout en identifiant des séquences et des régions préférées dudit acide nucléique cible, accessibles à une modulation oligonucléotidique ou séquentielle.
