The invention discloses Fmoc protected (2S)-2-amino-8-[(1,1- dimethylethoxy)amino]-8-oxo-octanoic acid, (S)-2-amino-8- oxononanoic acid and (S)-2-amino-8-oxodecanoic acid for use in peptide synthesis, such as solid phase synthesis, as well as the peptide H3K27 (Ac-Lys-Ala-Ala-Arg-Aox-Ser-Ala-NH2) prepared from Fmoc protected (2S)-2-amino-8-[(1,1-dimethylethoxy)amino]-8-oxo-octanoic acid (Aox). These three exemplary compounds as well as their unprotected forms are claimed in the form of four generic formulae. The first of these four formulae is (formula (I)) where -NPro is a protected amino group, such as an amino group protected with a base-labile protecting group, -L- is alkylene, heteroalkylene, arylene or aralkylene, -X- is a covalent bond, -N(H) - or -N(RN)-, where -RN is alkyl, -R2 is hydrogen or alkyl, -R3 is alkyl, such as C2-10 alkyl, or heterocyclyl, and -LAA- and -R1 are as defined in the claims.

libraries to the discovery of potent HDAC ligands using a convenient screening platform. Our studies led to the first HDAC6-selective cyclictetrapeptide analogue, which extends the use of cyclictetrapeptides to the class II HDAC isoforms. These findings highlight the persistent potential of cyclictetrapeptides as epigenetic modulators and possible anticancer drug lead compounds.
The synthesis of L-2-amino-8-oxodecanoic acid (Aoda) is described. This is a rare amino acid component of apicidins, a family of new cyclic tetrapeptides, inhibitors of histone deacetylase. Aoda was synthesised in seven steps fromL-glutamicacid, along with some derivatives.

We report the design, synthesis, and biological evaluation of the first macrocyclic peptoid-containing histone deacetylase (HDAC) inhibitors. The compounds selectively inhibit human class I HDAC isoforms in vitro, with no inhibition of the tubulin deacetylase activity associated with class IIb HDAC6 in cultured Jurkat cells. Compared to the natural product apicidin (1), one inhibitor (compound 10) showed equivalent potency against K-562 cells, but was more cytoselective across a panel of cancer cell lines.
Synthesis of 2-Amino-8-oxodecanoic Acids (Aodas) Present in Natural Hystone Deacetylase Inhibitors
Differently substituted 2-amino-8-oxodecanoic acids (Aodas), present in naturally occurring inhibitors of hystone deacetylase (HDAC), have been prepared using a convergent approach. The configuration in position 2 was derived from enantiomerically pure allylglycine or glutamic acid, whereas the stereochemistry of the substituent in position 9 derived from lactic acid or glyceraldehyde derivatives. Starting from allylglycine, (S)-Aodas, protected at the nitrogen as Boc or Fmoc, were obtained in four steps in about 30% overall yield. These products have been used to prepare a simplified analogue of a natural cyclic tetrapeptide HDAC inhibitor by SPPS.
