Sulfonamides as gpr40- and gpr120-agonists

A compound of formula (I):

• or a pharmaceutically acceptable salt thereof,
• wherein:
• A is a mono or di-carbocyclic residue, optionally partially or totally unsaturated, comprising carbon atoms and optionally one or more heteroatoms selected from N, S and O;
• R1, R2, R3 are independently selected from the group consisting of —H, -halogen, —CF3, —CN, —CH2CN, —OMe, —OCF3, —OH, phenyl, —OPh, —OCH2Ph, —OCH2OMe, —OCH2CN—NO2, —NR′R″, linear or branched C1-C6 alkyl, —O(CH2)p—S(O)2Me and a five-membered ring heterocycle;
• wherein R′ and R″ are independently —H or C1-C4 alkyl;
• wherein phenyl and the five-membered ring heterocycle are independently unsubstituted or substituted with a group selected from the group consisting of linear or branched C1-C4 alkyl, halogen, —OMe and —OH;
• p is 1 to 4;
• X is —CH2 or —C(O);
• n is 0, 1 or 2;
• R4 is —Y—C(O)OH, wherein Y is a straight chain C4-C18 hydrocarbon, saturated or unsaturated;
• R4 is in position meta or para on the aromatic ring;
• wherein when A is phenyl, n is 0, Y is a C4 hydrocarbon, at least one of said R1, R2, R3 is not hydrogen;
• wherein when A is phenyl, n is 0, Y is a C4 hydrocarbon, R1 and R2 are hydrogen, R3 is not Cl in position para on the aromatic ring.
