NOVEL ACC INHIBITORS

A compound having the structures: Formulae (Ia) or (Ib) or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate of said compound or pharmaceutically acceptable salt, wherein; R selected from the group consisting of H, C1-C6 alkyl, C1-C6 alkoxy and -(CH2)m-W, where W is C3-C8 cycloalkyl, bicycloalkyl, bridged bicycloalkyl, phenyl,, 5- or 6-membered heteroaryl or heterocyclic containing one, two or three heteroatoms selected from the group consisting of N, S and O atoms; wherein each of said alkyl, cycloalkyl, alkoxy, heterocyclic, phenyl, naphthyl or heteroaryl may be unsubstituted or substituted by phenyl, halo, cyano, deuterium, hydroxy, C1-C6 alkyl, C1-C6 alkoxy, -SO2-R', - CONR'R", NR'COR", -NR'CONR'R", -NR'CO2R", -(CH2)n-SO2-R', -NHSO2-R', -NR"SO2-R', - SO2NR'R", NR'R" or SR' where R' and R'' are independently H, C1-C6 alkyl or C3-C8 cycloalkyl; R1 selected from the group consisting of phenyl, naphthyl, 5- or 6-membered heteroaryl or heterocyclic containing one, two, three or four heteroatoms selected from the group consisting of N, S and O atoms; and, a 9- or 10-membered bicyclic aryl, heteroaryl or heterocyclic containing one, two or three heteroatoms selected from the group consisting of N, S and O atoms; wherein each of said phenyl, naphthyl, aryl, heterocyclic, or heteroaryl may be unsubstituted or substituted by halo, cyano, deuterium, hydroxy, C1-C6 alkyl, C1-C6 alkoxy, phenyl, -SO2-R', -CONR'R", NR'COR", -NR'CONR'R", -NR'CO2R", -(CH2)n-SO2-R', -NHSO2-R', -NR"SO2-R, -SO2NR'R", P(O)R'R", Formula (Ic), or NR'R"' or SR' where R' and R'' are independently H, C1-C6 alkyl or C3-C8 cycloalkyl; and, m and n are independently 0, 1, 2 or 3. The invention also relates to pharmaceutically acceptable salts of these compounds and to pharmaceutically acceptable solvates thereof; to compositions containing such compounds; and to the uses of such compounds in the treatment of various diseases, particularly acne. L'invention concerne un composé ayant les structures : (Ia) ou (Ib) ou un sel pharmaceutiquement acceptable de celui-ci, ou un solvate pharmaceutiquement acceptable dudit composé ou sel pharmaceutiquement acceptable; R est choisi dans le groupe constitué par H, alkyle en C1-C6, alcoxy en C1-C6 et -(CH2)m-W, W étant cycloalkyle en C3-C8, bicycloalkyle, bicycloalkyle ponté, phényle, hétéroaryle à 5 ou 6 chaînons ou hétérocyclique contenant un, deux ou trois hétéroatomes choisis dans le groupe constitué d'atomes N, S et O; ch
