Pyrimidine derivatives and their use in treating or preventing a respiratory syncytial virus infection

Abstract

Pyrimidine derivatives of formula (I) wherein: Z is a direct bond or —(CH2)n— wherein n is 1 or 2; one of X and Y is N, CH or CF, and the other of X and Y is CH; one of R1 and R2 is selected from —NHR, —NR2, —OR, —SR, —S(O)R, —S(O)2R and a group of the following formula (A) and the other of R1 and R2 is selected from —NHR′, —OH, —OR′ and a group of the above formula (A); R is unsubstituted C1-C6 alkyl; R′ is a group selected from C1-C6 alkyl, 5- to 12-membered aryl and C3-C6 cycloalkyl, which group is unsubstituted or substituted; W is —(CH2)m—, —CH2—O—CH2—, —CH2—S—CH2— or —CH2—S(O)2—CH2—; p is 1, q is an integer of 1-6 and V is N; or p is 1, q is 0 and V is CH; or p is 0, q is 0 and V is N; r is 0 or 1; and R3 is —(CH2)s—NH2 or —(CH2)s—OH wherein s is 0 or an integer of 1 to 4; and the pharmaceutically acceptable salts thereof are inhibitors of RSV and can therefore be used to treat or prevent an RSV infection.
