BRD7389 is a Rsk family kinase inhibitor. 
Rsk has been suggested to phosphorylate a large number of cellular substrates and plays an important role in promoting cell growth and survival. Knockdown of Rsk family members would have an effect on insulin production inα-cells. Increasing in insulin expression upon RNAi of individual Rsk proteins can be observed, but the effect is not as strong as compound treatment with BRD7389.
BRD7389 functions by inhibiting multiple Rsk family members simultaneously. BRD7389 also increases β-cell–specific gene expression in primary human islet cells. Assay-performance profile analysis suggests biochemical and cellular inhibition of the Rsk kinase family by BRD7389 is likely related to its ability induce a β-cell-like state. 
Treatment of TC1 cells with BRD7389 led to a decrease in the overall glycolytic activity and mitochondrial respiration rates, a phenotype reminiscent of the beta cell line. BRD7389 also increases the endocrine cell content and function of donor human pancreatic islets in culture.[2,3]
