Abstract: The present invention relates to novel compounds of formula (I) or pharmaceutically acceptable salt thereof: wherein G is selected from a group consisting of: phenyl, pyridyl, benzothiazolyl and indazolyl; p is an integer ranging from 0 to 5; R1 is independently selected from a group consisting of: halogen, hydroxy, cyano, C1-4alkyl, haloC1-4alkyl, C1-4alkoxy, haloC1-4alkoxy, C1-4alkanoyl and SF5; or corresponds to a group R5; each R2 is independently hydrogen, fluorine or C1-4alkyl; n is 2, 3, 4, or 5; R3 is C1-4alkyl; R4 is hydrogen, or a C1-4alkyl group, a benzyl group, a phenyl group, a heterocyclyl group, a 5- or 6-membered heteroaromatic group, or a 8- to 11-membered bicyclic group, any of which groups is optionally substituted by 1, 2, 3 or 4 substituents selected from the group consisting of: halogen, cyano, C1-4alkyl, haloC1-4alkyl, C1-4alkoxy, haloC1-4alkoxy, C1-4alkanoyl and SF5;or R4 is a —SR6 group; R5 is selected from a group consisting of: isoxazolyl, —CH2—N-pyrrolyl, 1,1-dioxido- 2-isothi
