Heterocyclic-substituted N,N'-diphenylurea derivatives (I) are new. Urea derivatives of formula (I) and their enantiomers, diastereomers and acid or base addition salts are new. R1 - R4 = H, halo, alkyl, alkoxy, OH, alkylthio, SH, CN, NH2, mono- or dialkylamino, NO2, COOH, alkoxycarbonyl, CONH2 or mono- or dialkylaminocarbonyl; or two adjacent groups together complete a fused benzene ring or a 5-7 membered heteroaryl ring containing 1-3 of N, O and/ore S as heteroatoms; L1, L2 = H or together form CH2CH2; X1 = direct bond (bonded in the 2- or 3-position of the ring); and X2 = H, halo, alkyl, alkoxy, OH, NO2, CN, NH2 or mono- or dialkylamino; or X1 + X2 = group forming a 4-7C ring with the C atoms in the 3- and 4-positions of the ring, 1 or 2 CH2 units of the ring optionally being replaced by O, NH or N(alkyl) and G being bonded to a ring C; X3 = H, halo, alkyl, alkoxy, OH, NO2, CN, NH2 or mono- or dialkylamino; G = heterocyclic group of formula (G1)-(G3); dotted line = optional bond; Alk = 1-6C alkylene, which must be bonded at the 2-position in an imidazoline ring of (G1); n, m = 0 or 1; T3, T4 = alkyl; or aryl, arylalkyl, heteroaryl or heteroarylalkyl (all optionally ring-substituted by one or more of halo, alkyl, alkoxy, OH, SH, alkylthio, CN, NH2, mono- or dialkylamino, NO2, COOH, alkoxycarbonyl, CONH2 or mono- or dialkylaminocarbonyl; heteroaryl rings may additionally be mono-substituted by oxo); aryl moieties = phenyl, naphthyl or biphenylyl; heteroaryl moieties = mono- or bicyclic group in which at least one ring is aromatic, containing 1-5 of N, O and/or S as heteroatom(s); alkyl moieties have 1-6C. Independent claims are included for the preparation of (I).
