The invention relates to novel products of the formula (I) where: (II) is a single or double bond; F is a fluorine atom, Ra is H, HaI, alkoxy, O-cycloalkyl, —O— heterocycloalkyl; —NH-heterocycloalkyl, heteroaryl, phenyl, NHCOalk NHCOcycloalk or NR1 R2; X is S, SO or SO2, A is NH or S; W is H, alkyl, or COR with R being cycloalkyl; alkyl optionally substituted by NR3R4, alkoxy, hydroxy, phenyl, heteroaryl or heterocycloalkyl; alkoxy optionally substituted by NR3R4, i.e. a O—(CH2)n-NR3R4 radical, an O-phenyl or an O—(CH2)n-phenyl radical, with phenyl optionally substituted and n=1 to 4; or the NR1 R2 radical; R1 is H or alk and R2 is H, cycloalkyl or alkyl; R3 and R4 are H, alk, cycloalkyl, heteroaryl or phenyl; R1, R2 and/or R3, R4 form a cycle together with N optionally containing O, S, N and/or NH; heterocycloalkyl, heteroaryl and phenyl and cycles all being optionally substituted; wherein said products can be in any isomer or salt form, and can be used as drugs, in particular as MET inhibitors.
