A high throughput screen was developed to identify novel, nonsteroidal ROR?
agonists. Among the validated hit compounds, the
4-(4-(benzyloxy)phenyl)-5-carbonyl-2-oxo-1,2,3,4-tetrahydropyrimidine scaffold
was the most prominent. Among the numerous analogues tested, compounds 8 and 9
showed the highest activity. Key structure-activity relationships (SAR) were
established, where benzyl and urea moieties were both identified as very
important elements to maintain the activity. Most notably, the SAR were
consistent with the binding mode of the compound 8 (S-isomer) in the ROR? docking
model that was developed in this program. As predicted by the model, the urea
moiety is engaged in the formation of key hydrogen bonds with the backbone of
Tyr380 and Asp382. The benzyl group is located in a wide hydrophobic pocket. The
structural relationships reported in this letter will help in further
optimization of this compound series and will provide novel synthetic probes
helpful for elucidation of complex ROR? physiopathology.
