st-Ht31 ammonium 

st-Ht31 ammonium is a membrane-permeable peptide inhibitor of protein kinase A (PKA) anchoring. st-Ht31 ammonium induces robust cholesterol/phospholipid efflux. st-Ht31 ammonium completely reverses foam cell formation and restores the metabolic health of macrophage^[1][2].

st-Ht31 (5 µM; 2 h) ammonium enhances cholesterol/phospholipid efflux in BHK cells and RAW macrophages^[1].
st-Ht31 (10µM; 24 h) ammonium reverses foam cell formation and restores metabolic health of macrophage^[1].
st-Ht31 (20 µM; 20 min) ammonium abolishes the cAMP inhibition of PMA-induced ERK1/2 activation n HEK293T cells^[2].
