LXXLL-containing peptide fragment of the coactivator (where L is leucine and X is any amino acid), which adopts a partially α-helical conformation, benzodiazepine molecules were rationally designed as non-peptide coactivatormimetics. TR-FRET assay showed that the synthesized compounds inhibited the interaction between VDR and a coactivatorpeptide fragment. Compound 2 showed an IC50 of 20 μM. Compound
