      Alomone Labs KT5720 inhibits PKAS phosphorylation via PKA.
      NIH/C6 cells were preincubated for 45 min with different concentrations of KT5720 (#K-190) and then stimulated with 10 µM Forskolin (#F-500) for 20 min. Cell proteins were resolved by SDS-PAGE and probed with antiphospho-(Ser/Thr) PKAS (PKA substrate).

    Scientific background KT5720 is a semi-synthetic derivative of K525a. It is a cell-permeable, selective inhibitor of cAMP-dependent protein kinase (PKA; IC50 = 56 nM). No significant effect on protein kinase C (PKC), protein kinase G (PKG) or myosin light chain kinase (MLCK), was observed.1 KT5720 was used to examine the role of PKA in various cellular events such as cell adhesion,2 neurite branching,3 anterograde axonal transport,4 memory consolidation,5,6 and regulation of transcription by cyclic AMP-dependent response element-binding protein (CREB).7
