Abstract
A series of ERbeta selective DPN analogs were prepared where the both the ligand core and the aromatic rings were modified by the repositioning of phenolic hydroxy groups and by the addition of alkyl substituents and nitrile groups. Another series of DPN analogs were synthesized where the nitrile functionality was replaced with acetylene groups or polar groups to mimic the linear geometry or the polarity of the nitrile. All of the analogs are affinity selective for ERbeta to varying degrees, but many are not potency selective. meso- and dl-2,3-bis(4-hydroxyphenyl)succinonitrile are among the highest ERbeta affinity selective ligands and have somewhat greater ERbeta potency selectivity than DPN. The nitrile functionality was found to be critical to ERbeta selectivity as it is the optimal combination of linear geometry and polarity. Furthermore, the addition of another nitrile group beta to the nitrile or ortho methylation of the aromatic ring increases the affinity and selectivity of these compounds for ERbeta.
