Abstract

Background: The pyrazolyl ketone motif of RO3201195, which exhibits good oral bioavailability and high selectivity for p38 MAPK over other kinases, is a key pharmacophore that could find application in the treatment of Werner syndrome. Results and discussion: Microwave irradiation promotes Knoevenagel condensation of a β-ketonitrile and formamidine, to give β-aminovinyl ketones, and their subsequent cyclocondensation with a subset of hydrazines to provide rapid access to a 24-membered library of pyrazolyl ketones. The library was evaluated in human hTERT-immortalized HCA2 dermal cells and Werner syndrome cells. Conclusion: Four compounds display comparable, if not slightly improved, potency over RO3201195.
