Abstract
This invention concerns the use of compounds of formula (I) wherein -a1=a2−a3=a4- is a radical of for CH═CH—, —N═CH—CH═CH—, —CH═N—CH═CH—, —CH═CH—N═CH—, —CH═CH—CH═N— wherein each hydrogen atom may optionally be substituted; Q is a radical of formulas (b-1), (b-2), (b-3), (b-4), (b-5), (b-6), (b-7), (b-8). G is a direct bond or C1-10alkanediyl; R1 is an optionally substituted monocyclic heterocycle; for the manufacture of a medicament for the treatment of viral infections, in particular RSV infections. Certain compounds of formula (I) are new.
