An efficient method to synthesize a novel rigid tricyclic peptidomimetic scaffold through ring-closure of amino-functionalized bicyclic 2-pyridones has been discovered. The scaffold can function as a peptide backbone mimetic (highlighted) with two substituents independently variable to fine-tune biological response. Halogenation of the pyrazolo ring followed by Suzuki couplings made it possible to
