Using fragment-based screening techniques, 5-methyl-4-phenyl-1H-pyrazole (IC50 80 microM) was identified as a novel, low molecular weight inhibitor of protein kinase B (PKB). Herein we describe the rapid elaboration of highly potent and ligand efficient analogues using a fragment growing approach.

Novel Aurora inhibitors were identified truncating clinical candidate GSK1070916. Many of these truncated compounds retained potent activity against Aurora B with good antiproliferative activity. Mechanistic studies suggested that these compounds, depending on the substitution pattern, may or may not exert
