-
Paragraph 728; 729, (2015/10/05)
The present invention relates to novel compounds having histone deacetylase 6 (HDAC6) inhibitory activity, isomers thereof, or pharmaceutically acceptable salts thereof, the use thereof for the preparation of therapeutic medicaments, pharmaceutical compositions comprising the same, a method of treating disease using the composition, and methods for preparing the novel compounds. The novel compounds according to the present invention have histone deacetylase 6 (HDAC6) inhibitory activity, and are effective for the prevention or treatment of HDAC6-associated diseases, including cancer, inflammatory diseases, autoimmune diseases, neurological diseases and neurodegenerative disorders.

Starting from cinnamates 9, obtained by Wittig reaction or Heck coupling, the diols 17 were prepared by asymmetric dihydroxylation. This was followed by a regioselective substitution of the 3-OH group with hydrazoic acid under Mitsunobu conditions. Methylation of the 2-OH group and reduction of the azide group led to the β-tyrosine derivatives 8. Condensation with the dipeptide acid 6 furnished the tripeptide part of the chondramides. The derived acids 21 were combined with the hydroxy ester 7 to the esters 22. Cleavage of the tert-butyl groups and intramolecular lactam formation gave rise to the chondramide A analogues 2 b-k. Growth inhibition assays showed most of the analogues to be biologically active. Some of them even reach the activity of jasplakinolide. It can be concluded that the 4-position of the aryl ring in the β-tyrosine of chondramide A tolerates structural modifications quite well.

The binding of therapeutically relevant synthetic retinoid derivatives to bovine and reindeer β-lactoglobulin (βLG) is demonstrated using fluorescence quenching and ultrafiltration/HPLC methods. Furthermore, synthesis of methyl (E)-3-[4-[(E)-2-(2,6,6-trimethylcyclohex-1-enyl)vinyl]phenyl]-acrylate 4 and (E)-3-[4-[(E)-2-(2,6,6-trimethylcyclohex-1-enyl)vinyl]phenyl]acrylic acid 5 is described. All studied compounds bind to both βLG homologues with nanomolar Kd values, and the interaction diminishes the pH-dependent aggregation of retinoids. Thus, βLG may show benefits in improving the bioavailability of retinoid derivatives.
