spiruchostatin bicyclic depsipeptide natural products are among the most potent histone deacetylase (HDAC) inhibitors known. Although FK228 is in advanced clinical trials, the complexity of the natural products has precluded mechanistic studies and the discovery of structure-activity relationships. By totalsynthesis, we have prepared the first depsipeptide analogues. Our results prove that the dehydrobutyrine

[EN] Compounds which are FK228 analogues of the general formula (I) or (I/), isosteres thereof and pharmaceutically acceptable salts thereof are found to inhibit HDAC wherein R1, R2, R3 and R4 are the same or different and represent an amino acid side chain moiety and each R6 is the same or different and represents hydrogen or C1-C4 alkyl. [FR] L'invention concerne des composés qui sont des analogues de FK228 représentés par la formule générale (I) ou (I/), des isostères de ces derniers et des sels pharmaceutiquement acceptables de ces derniers qui se sont avérés inhiber l'HDAC. Dans ladite formule, R1, R2, R3 et R4 sont identiques ou différents et représentent un fragment de chaîne latérale d'un acide aminé et chaque R6 est identique ou différent et représente hydrogène ou alkyle C1-C4.
