The invention relates to a guanidine derivative of the formula:
in which X is O or S; Y is N or CH; n is 1 to 4; m ist O or 1; R1 is H, C(1-6)alkyl or C(3-10)alkoxyalkyl; -R2 is -A-B in which A is 3,4-dioxocyclobuten-1,2-dlyl or C=Z In which Z is O, S. NCN, NNO2, CHNO2, NCONH2, C(CN)2, NCOR3, NCO2R3, NSO2R3 or NR4 In which R3 is C(1-6)alkyl, phenyl or a monocyclic heteroaromatic ring containing 1 or 2 heteroatoms selected from O, N and S and R4 is H or C(1-6)alkyl; B is C(1-6)Alkyl, alkoxy or alkylthio or NHR5 in which R5 is H or C(1-6)alkyl, C(3-10)alkenyl or alkynyl, C(3-6)cycloalkyl, C(2-6)(primary hydroxy)alkyl or (primary amino)alkyl, C(1-6)haloalkyl, C(3-6)alkoxyalkyl, phenylalkyl or monocyclic aromatic heterocyclylakyl In which the alkyl part is C(1-6). the phenyl carries an optional halogen and the heterocyclic ring contains 1 or 2 hetero atoms selected from O, N and S, or R5 is benzoylaminoalkyl or benzenesulphonylaminoalkyl in which alkyl part is C(2-6) and the benzene ring carries an optional Cl substituent, or a radical of the formula:
in which X, Y, n, m and R1 are as above, p is 2 to 12 and G is S or CH2 or -R2 is a radical of the formula:
or
and the salts thereof.
