  Scaffold Hopping and Optimization of Maleimide Based Porcupine Inhibitors

  摘要：

  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.

  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, N-3, Cl, NO2), sufficiently strong CH-acids (pK(a) 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 pK(a) 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.

• Unique Azolyl Acylhydrazonyl Hybridization of Aloe Emodins to Access Potential Antibacterial Agents

  Comprehensive SummaryA type of unique azole‐hybridized acylhydrazonyl aloe emodins (AAEs) were developed as new antibacterial agents for combating bacterial infections. Some target AAEs showed strong antibacterial activities, especially, tetrazolylthioether AAE 27a exhibited broad antibacterial spectrum with 16—256 folds and 8—64 folds more active antibacterial efficacy than the reference drugs aloe emodin and norfloxacin, respectively. Tetrazolylthioether AAE 27a also gave low hemolysis and cytotoxicity, as well as favorable bioavailability. Preliminary mechanism explorations revealed that tetrazolylthioether AAE 27a could cause bacterial membrane depolarization and damage the cell membrane, resulting in nucleic acid leakage. Moreover, compound 27a could intercalate into DNA to impede its replication and form supramolecular 27a‐DNA gyrase complex to disturb the function of DNA gyrase. These findings would provide valuable insights for the further exploration of azolyl acylhydrazonyl aloe emodins as new potential antibacterial candidates.
