Development of neuroinflammation agents targeting the translocator protein (TSPO) has been hindered by a common single nucleotide polymorphism (A147T) at which TSPO ligands commonly lose affinity. To this end, carbazole acetamide scaffolds were synthesized and structure activity relationships elaborated to explore the requirements for high-affinity binding to both TSPO wild type (WT) and the polymorphic TSPO A147T. This study reports high binding affinity and nondiscriminating TSPO ligands.
Design, synthesis and biological evaluation of novel Pseudomonas aeruginosa DNA gyrase B inhibitors
In the present study, we attempted to develop a novel class of compounds active against Pseudomonasaeruginosa (Pa) by exploring the pharmaceutically well exploited enzyme targets. Since, lack of Pa gyrase B crystal structures, Thermus thermophilus gyrase B in complex with novobiocin (1KIJ) was used as template to generate model structure by performing homology modeling. Further the best model was
A series of novel 2-hydroxyphenyl substituted aminoacetamides was designed by molecular hybridization of the aminoacetamide scaffold and 2-hydroxyphenyl motif. The target compounds were synthesized and their fungicidal activities were evaluated. Some of the target compounds showed excellent antifungal activities against S. sclerotiorum and P. capsici. Significantly, compounds 5e displayed the most
