1. A compound of formula (I):

  • ##STR9## wherein Q1 is;

    a heterocyclic group selected from unsubstituted or substituted indolyl, benzothiophenyl and benzofuranyl, said substituents selected from C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, halo, cyano, nitro, trifluoromethyl, trimethylsilyl, SRa, SORa, SO2 Ra, ORa, NRa Rb, NRa CORb, NRa COORb, COORa or CONRa Rb, where Ra and Rb are defined below;

    the dotted line represents an optional covalent bond;

    one of X and Y represents H and the other of X and Y represents hydroxy or C1-6 alkoxy, or X and Y together form a group ═

    O or ═

    NOR5 where R5 is selected from H and C1-6 alkyl;

    R1 and R2 are each independently selected from H;

    C1-6 alkyl optionally substituted by hydroxy, cyano, CORc, CO2 Rc, CONRc Rd, or NRc Rd (where Rc and Rd are each independently selected from H, C1-6 alkyl and phenyl (C0-4 alkyl) optionally substituted in the phenyl ring by one or more of C1-6 alkyl, C1-6 alkoxy, halo and trifluoromethyl);

    phenyl (C1-4 alkyl) (optionally substituted in the phenyl ring by one or more of C1-6 alkyl, C1-6 alkoxy, halo and trifluoromethyl);

    CORc ;

    CO2 Rc ;

    CONRc Rd ;

    COC1-6 alkylNRc Rd ;

    CONRc COORd ; and

    SO2 Rc ;

    where Rc and Rd are as above defined;

    R3 is selected from H, C1-6 alkyl and C2-6 alkenyl; and

    R4 is phenyl optionally substituted by 1, 2, or 3 groups selected from C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, halo, cyano, nitro, trifluoromethyl, trimethylsilyl, ORa, SRa, SORa, NRa Rb, NRa CORb, NRa CO2 Rb, CO2 Ra and CONRa Rb, where Ra and Rb are independently selected from H, C1-6 alkyl, phenyl and trifluoromethyl;

    or a pharmaceutically acceptable salt thereof.
