The invention relates to new and known tricyclic dione derivatives of the general formula
wherein
Wrepresents hydrogen or lower alkyl;
Xrepresents lower alkyl;
Yrepresents an oxygen atom or NR1;
R1represents hydrogen, lower alkyl, lower alkoxycarbonyl or lower alkoxycarbonyl-lower alkyl;
Zrepresents aryl or heteroaryl optionally substituted by one or more halo, cyano, nitro, lower alkyl, halo-lower alkyl, lower alkoxy, halo-lower alkoxy, COR2, OCOR2, CO2R2, OR2, S(O)nR2, NR2R3, N(R4)COR5, Ar, Ar-lower alkyl, Het or Het-lower alkyl substituents and/or on adjacent carbon atoms by lower alkylenedioxy;
R2, R3, R4 and R5each individually represent hydrogen, lower alkyl, Ar, Ar-lower alkyl, Het or Het-lower alkyl substituents; or R2 and R3 together represent the group -CH=CH-CH=CH- or -CH=N-CH=CH-;
Arrepresents aryl optionally substituted by one or more halo, lower alkyl, lower alkoxy or nitro substituents;
Hetrepresents heteroaryl optionally substituted by one or more halo, lower alkyl, lower alkoxy or nitro substituents; and
nstands for 0, 1 or 2
and to their salts which are inhibitors of herpes simplex virus thymidine kinase in the treatment and prophylaxis of infections caused by herpes simplex virus.
