Synthesis of Benzamides Related to Anacardic Acid and Their Histone Acetyltransferase (HAT) Inhibitory Activities

CHEMMEDCHEM, Issue 9 2008

Abstract A group of benzamides related to anacardic acid amide CTPB with alkyl chains of defined length were prepared by a five-step sequence starting from 2,6-dihydroxybenzoic acid, and their activities were compared with those reported for the HAT inhibitor anacardic acid (AA). The subset of 4-cyano-3-trifluoromethylphenylbenzamides with shorter chains exhibited activities similar to that of AA, as they behaved as human p300 inhibitors, induced a decrease in histone acetylation levels in immortalized HEK cells, and counteracted the action of the HDAC inhibitor SAHA in MCF7 breast cancer cells. Moreover, an analogue with the shortest alkyl chain induced significant apoptosis at 50,,M in U937 leukemia cells. [source]

The Transcriptional Coactivator p300 Plays a Critical Role in the Hypertrophic and Protective Pathways Induced by Phenylephrine in Cardiac Cells but Is Specific to the Hypertrophic Effect of Urocortin

Abstract Anacardic acid is an alkylsalicylic acid obtained from cashew-nut-shell liquid, and is a potent inhibitor of p300 histone acetyl-transferase (HAT) activity. We have used anacardic acid to prevent the induction of hypertrophy in isolated neonatal rat cardiomyocytes. Hypertrophy was detected as an increase in cell size, the rearrangement of sarcomeres into a striated pattern, and the induction of embryonic genes ,-MHC and ANF. p300 inhibition was equally effective at preventing hypertrophy whether it was induced by treatment with the ,1-adrenergic agonist, phenylephrine, or by treatment with urocortin, a member of the corticotrophin-releasing-factor family, which stimulates specific G protein-coupled receptors. Spiruchostatin A is a natural-product inhibitor of histone deacetylases (HDAC) similar to the depsipeptide FK228 molecule. We have recently synthesized spiruchostatin A and now show that, although HDACs act in opposition to HATs, spiruchostatin A has the same effect as anacardic acid, that is, it prevents the induction of hypertrophy in response to phenylephrine or urocortin. Pretreatment with either phenylephrine or urocortin reduced the extent of death observed after the exposure of isolated cardiomyocytes to simulated ischaemia and reoxygenation. Inhibition of p300 or HDAC activity eliminated the protection conferred by phenylephrine; however, it did not affect the protection conferred by urocortin. Therefore, it might eventually be possible to use chemical inhibitors such as these in a therapeutic setting to dissociate the protective effect and hypertrophic effect of urocortin, enhancing the survival of cardiomyocytes exposed to transient ischemia, while inhibiting the hypertrophic pathway that would otherwise be induced concurrently.
