Herein we report the discovery of pyrazolocarboxamides as novel, potent, and kinase selective inhibitors of receptor interacting protein 2 kinase (RIP2). Fragment based screening and design principles led to the identification of the inhibitor series, and X-ray crystallography was used to inform key structural changes. Through key substitutions about the N1 and C5 N positions on the pyrazole ring significant kinase selectivity and potency were achieved. Bridged bicyclic pyrazolocarboxamide 11 represents a selective and potent inhibitor of RIP2 and will allow for a more detailed investigation of RIP2 inhibition as a therapeutic target for autoinflammatory disorders.

Squaric acid and its derivatives are versatile synthons and have demonstrated applications in medicinal chemistry, notably as non-classical bioisosteric replacements for functional groups such as carboxylic acids, alpha-amino acids, urea, guanidine, peptide bonds and phosphate/pyrophosphate linkages. Surprisingly, no reports have appeared concerning its possible application as a nucleobase substitute in nucleosides. A preliminary investigation of such an application is reported herein. 3-Amino-4-((1R,4S)-4-(hydroxymethyl)cyclopent-2-en-1-yl)amino-cyclobut-3-ene-1,2-dione, 3-((1R,4S)-4-(hydroxymethyl)cyclopent-2-en-1-yl)amino-4-methoxycyclobut-3-ene-1,2-dione, and 3-hydroxy-4-((1R,4S)-4-(hydroxymethyl)cyclopent-2-en-1-yl)amino-cyclobut-3-ene-1,2-dione sodium salt were synthesized. Computational analyses of their structures and preliminary antitumor and antiviral screening results are reported.
