The @-unsaturated ketone (4,4-dimethyl-2-ethyl-1 [4H]naphthalenon-6-y1)oxyacetic acid (III), a cyclic analog of ethacrynic acid, has been prepared, and its diuretic activity on oral administration to rats and dogs has been evaluated. No significant activity was observed. Keyphrases 0 Ethacrynic aci
Synthesis of nine macrocyclic peptide HDAC inhibitors and three triazole derivatives are described. HDAC inhibitory activity of these compounds against HeLa cell lysate is evaluated. The biological data demonstrates that incorporation of a triazole unit improves the HDAC inhibitory activity.
