Abstract: The invention provides a compound of Formula (I) or a tautomer, isomer, prodrug, metal complex, or pharmaceutically acceptable salt thereof for use in the treatment of a metabolic disorder or for inducing weight loss: wherein R1 is: H; a straight or branched alkyl; a straight or branched alkyl substituted with at least one moiety selected from the group comprising: halogen, hydroxy, alkoxy, NH2, mono- or disubstituted amino, thiol, and phosphine; aryl; aralkyl; hydroxy; alkoxy; aryloxy; arylalkoxy; NH2; mono- or disubstituted amino; or halogen; X is: CH or N; L is absent or present, and when present is: an optionally substituted straight or branched C1-C10 alkyl, optionally containing one or more rings, and/or optionally containing one or more double bonds; and Ar is: an optionally substituted 5-membered unsaturated heterocyclic ring.

Abstract: The invention provides a compound of Formula (I) or a tautomer, isomer, prodrug, metal complex, or pharmaceutically acceptable salt thereof for use in the treatment of a metabolic disorder, wherein R1 is: a straight or branched C1-C20 alkoxy, preferably C1-C10 alkoxy group, optionally containing one or more rings, and/or optionally containing one or more double bonds; an alkoxycarbonyloxyalkoxy group bearing a straight, branched or cyclic alkyl; an aryloxy group; or an arylalkoxy group; R2 and R3 which can be the same or different, are: hydrogen; a straight or branched C1-C20 alkylcarbonyl or cyclic C3-C7 alkylcarbonyl group optionally containing one or more double bonds; an arylcarbonyl or arylalkylcarbonyl group; a straight or branched C1-C10 alkoxycarbonyl or cyclic C3-C7 alkoxycarbonyl group optionally containing one or more double bonds; an arylalkoxy carbonyl group; an amino group; a hydroxy group; or a group of general Formula (II) wherein Y is nitrogen, oxygen or sulfur and A is hydrogen or an amino g
