Reductive denitration of 1-trinitromethyl-3-R-1,2,4-triazoles by KI or NH2OH followed by the treatment of the formed 1-dinitromethyl-3-R-1, 2,4-triazoles salts with sulfuric acid yielded dinitromethyl compounds (R = H, N3, Cl, NO2), sufficiently strong CH-acids (pKa 1.37-0.12) whose typical reactions are similar to those of gem-dinitrocompounds from the aliphatic series. The spectral data and the analysis of correlation relations between pKa of 1-dinitromethyl-3-R-1,2,4-triazoles and the substituent constants confirm that their structure is analogous to that of the majority of compounds belonging to the mentioned series.

Porcupine is an O-acyltransferase that regulates Wnt secretion. Inhibiting porcupine may block the Wnt pathway which is often dysregulated in various cancers. Consequently porcupine inhibitors are thought to be promising oncology therapeutics. A high throughput screen against porcupine revealed several potent hits that were confirmed to be Wnt pathway inhibitors in secondary assays. We developed a pharmacophore model and used the putative bioactive conformation of a xanthine inhibitor for scaffold hopping. The resulting maleimide scaffold was optimized to subnanomolar potency while retaining good physical druglike properties. A preclinical development candidate was selected for which extensive in vitro and in vivo profiling is reported.
