The present invention concerns compounds that are capable of covalently entrapping adenylating enzymes. The present invention is essentially based on the discovery that analogues of adenylating enzyme (AE) substrates, wherein a methylene group has been incorporated at the carbon atom in the α-position relative to the carboxylate group involved in the adenylation, are capable of undergoing the adenylation reaction, thereby creating an activated methylene group in situ. The resulting ‘armed’ acyladenylate can interact with the enzyme resulting in covalent entrapment. Interestingly, the acyladenylate can alternatively be transferred to the next step in the enzyme cascade, following which the activated methylene group can interact with the next (active site cysteine containing) enzyme in the enzymatic cascade. The AE substrate analogues, based on their capability of ‘entrapping’ the respective enzymes, will have utility as activity based probes in biological research and also as diagnostic and/or therapeutic agents.

(EN) The present invention relates to the use as antivirals of compounds of formula (I), wherein B is a purinic or pyrimidinic heterocycle; X is oxygen or sulphur; R1 is a hydroxyl group or a hydrogen atom; R2 is a linear, branched or cyclic, alkyl group of up to twenty carbon atoms; R3 is as specified for R2 above or a hydrogen atom, a cation or a polyhydroxy group.(FR) On prévoit l'utilisation en tant qu'agents antiviraux des composés de formule (I), où B est un hétérocycle purique ou pyrimidique; X est oxygène ou soufre; R1 est un groupe hydroxyle ou un atome d'hydrogène; R2 est un groupe alkyle linéaire, ramifié ou cyclique possédant jusqu'à vingt atomes de carbone; R3 est le même que R2 ci-dessus ou est un atome d'hydrogène, un cation ou un groupe polyhydroxy.
