Application

A-485 has been used as a p300 regulated RelA acetylation inhibitor to study the effect of fatty acid oxidation (FAO) derived cytoplasmic acetyl-CoA on CD47 transcription and protein stability via citrate/acetyl-CoA mediated RelA acetylation in glioblastoma.

Biochem/physiol Actions

A-485 exhibits an anti-tumor effect and may show therapeutic effects against the growth hormone pituitary adenoma (GHPA). It can specifically block the acetylation of histone H3 lysine 27 (H3K27) and lysine 18 (H3K18) sites catalyzed by p300.
A-485 is a potent and selective catalytic inhibitor of the p300 and CREB-binding protein (CBP) histone acetyltransferases (HATs) with an IC50 value of 60 nM. A-485 was most active against haematological malignancies including most multiple myeloma cell lines as well as androgen receptor-positive prostate cancer. It was also shown to inhibit the proliferation of castration-resistant prostate cancer cells and in vivo tumour growth in SCID mice.

The dynamic and reversible acetylation of proteins, catalysed by histone acetyltransferases (HATs) and histone deacetylases (HDACs), is a major epigenetic regulatory mechanism of gene transcription and is associated with multiple diseases. Histone deacetylase inhibitors are currently approved to treat certain
