We have developed two novel series of tetrasubstituted pyrazoles, embodying 1,3-diaryl-4,5-dialkyl or 3,5-diaryl-1,4-dialkyl substitution patterns. The scope of a regioselective method, developed by us earlier, was expanded to allow the synthesis of the first series of these tetrasubstituted pyrazoles directly from α,β-unsaturated ketones. The binding affinity of some of these pyrazoles for the estrogen receptor (ER) subtypes ERα and ERβ is very high, and the overall affinity pattern suggests the importance of three phenol substituents for high affinity, ERα-selective binding.
