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.
式(I)的嘧啶衍生物 其中Z为直接键或-(CH2)n-,其中n为1或2;X和Y中的一个为N、CH或CF,X和Y中的另一个为CH;R1和R2中的一个选自-NHR、-NR2、-OR、-SR、-S(O)R、-S(O)2R和下式(A)的一个基团,R1和R2中的另一个选自-NHR′、-OH、-OR′和上式(A)的一个基团;R 是未取代的 C1-C6 烷基;R′是选自 C1-C6 烷基、5-至 12 元芳基和 C3-C6 环烷基的基团,该基团是未取代或取代的;W 是-(CH2)m-、-CH2-O-CH2-、-CH2-S-CH2-或-CH2-S(O)2-CH2-;p 是 1,q 是 1-6 的整数,V 是 N;或 p 是 1,q 是 0,V 是 CH;或 p 是 0,q 是 0,V 是 N;r 是 0 或 1;和 R3 是-(CH2)s-NH2 或-(CH2)s-OH,其中 s 是 0 或 1 至 4 的整数;及其药学上可接受的盐类是 RSV 的抑制剂,因此可用于治疗或预防 RSV 感染。
