The invention relates to the use of a compound of the formula (I), or a pharmaceutically acceptable salt thereof, for the manufacture of a medicament for use in modulating an immune or inflammatory response: wherein: Z = O or S; n = 1 - 3; R3 = -CO2R8, -C(O)SR8, -C(O)NHR8,-C(S)OR8, -C(S)SR8, -C(S)NHR8, -C(NH)SR8 or -C(NH)NHR8, wherein R8 is -H or alkyl; R4 = -H, -CH2R5 or -CH2CH2R5, wherein R5 independently has one of the meanings of R3; B = -NR2-, -CH2NR2-, -CH2CH2NR2-, -CH2CHR7- or -CH2O-, wherein R2 is H or a C1-3 alkyl, alkenyl or alkynyl group, and R7 is H or a C1-3 alkyl or alkoxy group; A = wherein R1 = -NH2 or -OH, C and D are each, independently, a 5- or 6-membered, substituted or unsubstituted, aromatic or non-aromatic ring which may also contain one or more heteroatoms, and C is connected to group B in any available position.

La présente invention concerne l'utilisation d'un composé de la formule (I), ou d'un sel pharmaceutiquement acceptable de celui-ci, pour la fabrication d'un médicament à utiliser dans la modulation d'une réponse immune ou inflammatoire : où Z = O ou S ; n = 1 - 3 ; R3 = -CO2R8, -C(O)SR8, -C(O)NHR8,-C(S)OR8, -C(S)SR8, -C(S)NHR8, -C(NH)SR8 ou -C(NH)NHR8, où R8 correspond à -H ou à l'alkyle ; R4 = -H, -CH2R5 ou -CH2CH2R5, où R5 a indépendamment une des significations de R3 ; B = -NR2-, -CH2NR2-, -CH2CH2NR2-, -CH2CHR7- ou -CH2O-, où R2 correspond à H ou à un alkyle de C1-3, à un groupe d'alcényle ou d'alkynyle, et R7 correspond à H ou à un groupe d'alkyle ou d'alkoxy C1-3 ; A = où R1 = -NH2 ou -OH, C et D correspondent, indépendamment, à un anneau aromatique ou non aromatique, substitué ou non substitué, à 5 ou 6 éléments qui peut également contenir un ou plusieurs hétéroatomes, et C est relié au groupe B dans une quelconque position disponible.
