A structure-activity relationship (SAR) study of the c-Myc (Myc) inhibitor 10074-G5 (N-([1,1′-biphenyl]-2-yl)-7-nitrobenzo[c][1,2,5]oxadiazol-4- amine, 1) - which targets a hydrophobic domain of the Myc oncoprotein that is flanked by arginine residues - was executed in order to determine its pharmacophore. Whilst the 7-nitrobenzofurazan was found to be critical for inhibitory activity, the ortho-biphenyl could be replaced with a para-carboxyphenyl group to furnish the new inhibitor JY-3-094 (3q). Around five times as potent as the lead with an IC50 of 33 μM for disruption of the Myc-Max heterodimer, JY-3-094 demonstrated excellent selectivity over Max-Max homodimers, with no apparent effect at 100 μM. Importantly, the carboxylic acid of JY-3-094 improves the physicochemical properties of the lead compound, which will facilitate the incorporation of additional hydrophobicity that might enhance Myc inhibitory activity further still.
