Lacking insight into the binding mode, initial attempts to improve inhibitor potency failed to improve potency, and synthesis of analogs was further hampered by the presence of a C-C bond between the pyrrolidine and pyridine. Replacing this with a C-N bond significantly simplified synthesis, yielding pyrazole analog, [3-(4-bromo-1<em>H<\/em>-pyrazol-1-yl)-1-pyrrolidinyl][5-(1-methylethyl)-1<em>H<\/em>-pyrazol-3-yl]methanone (35), of which the authors obtained a co-crystal structure with KDM5A. Using structure-based design approach, the authors identified, <em>N<\/em>-[(3<em>R<\/em>)-1-[[5-(1-methylethyl)-1<em>H<\/em>-pyrazol-3-yl]carbonyl]-3-pyrrolidinyl]cyclopropanecarboxamide (50), with improved biochem., cell potency and reduced MW and lower lipophilicity (Log D) compared with the original hit. Furthermore, 50 showed lower clearance than [5-(1-methylethyl)-1<em>H<\/em>-pyrazol-3-yl][(3<em>S<\/em>)-3-[6-methyl-4-(1-methyl-1<em>H<\/em>-pyrazol-4-yl)-2-pyridinyl]-1-pyrrolidinyl]methanone (9) in mice. In combination with its remarkably low plasma protein binding (PPB) in mice (40%), oral dosing of 50 at 5 mg\/kg resulted in unbound C<sub>max<\/sub> \u223c2-fold of its cell potency (PC9 H3K4Me3 0.96 \u03bcM), meeting the authors&#8217;
