b) hydrogen, C₁-C₆ alkoxy or C₃-C₄ alkenyloxy; or
c) nitro, amino, formylamino or C₂-C₈ alkanoylamino;
R₄ represents hydrogen or C₁-C₆ alkyl; and
Q represents hydrogen, carboxy, CONH₂, C₂-C₇ alkoxycarbonyl
wherein Ra represents hydrogen or C₁-C₂₀ alkyl and Rb represents C₁-C₂₀ alkyl or a -(CH₂)m-R₅ group, wherein m is zero, 1 or 2 and R₅ is:
aʹ) C₅-C₈ cycloalkyl;
bʹ) pyridyl, unsubstituted or substituted by one or two substituents chosen independently from halogen, C₁-C₆ alkyl and C₁-C₆ alkoxy; or
cʹ) phenyl, unsubstituted or substituted by one or two substituents independently chosen from halogen, CF₃, C₁-C₆ alkyl, C₁-C₆ alkoxy, amino, nitro, formylamino, C₂-C₈ alkanoylamino, di (C₁-C₆ alkyl) amino, hydroxy, formyloxy and C₂-C₈ alkanoyloxy, and the pharmaceutically acceptable salts thereof, which possess immunodulating activity and are useful e.g. in the treatment of neoplastic diseases and acute and chronic infections of both bacterial and viral origin in mammals.
