'''STRUCTURE OF PKA COMPLEXED WITH 4-(4-CHLOROBENZYL)-1-(7H-PYRROLO(2,3-D)PYRIMIDIN-4-YL)PIPERIDIN-4-YLAMINE'''
===STRUCTURE OF PKA COMPLEXED WITH 4-(4-CHLOROBENZYL)-1-(7H-PYRROLO(2,3-D)PYRIMIDIN-4-YL)PIPERIDIN-4-YLAMINE===




==Overview==
<!--  
Fragment-based screening identified 7-azaindole as a protein kinase B inhibitor scaffold. Fragment elaboration using iterative crystallography of inhibitor-PKA-PKB chimera complexes efficiently guided improvements in the potency and selectivity of the compounds, resulting in the identification of nanomolar 6-(piperidin-1-yl)purine, 4-(piperidin-1-yl)-7-azaindole, and 4-(piperidin-1-yl)pyrrolo[2,3- d]pyrimidine inhibitors of PKBbeta with antiproliferative activity and showing pathway inhibition in cells. A divergence in the binding mode was seen between 4-aminomethylpiperidine and 4-aminopiperidine containing molecules. Selectivity for PKB vs PKA was observed with 4-aminopiperidine derivatives, and the most PKB-selective inhibitor (30-fold) showed significantly different bound conformations between PKA and PKA-PKB chimera.
