Synthesis and NMR Analysis of a Conformationally Controlled β-Turn Mimetic Torsion Balance

10-Jan-2017 | Alyssa B. Lypson; Craig S. Wilcox, The Journal of Organic Chemistry, 2017

The molecular torsion balance concept was applied to a new conformationally controlled scaffold and synthesized to accurately evaluate pairwise amino acid interactions in an antiparallel β-sheet motif. The scaffold’s core design combines (ortho-tolyl)amide and o,o,o′-trisubstituted biphenyl ...

Brominated Graphene as Mimetic Peroxidase for Sulfide Ion Recognition

22-Dec-2016 | Shikha Singh; Kheyanath Mitra; Aparna Shukla; Rajshree Singh; Ravi Kumar Gundampati; Nira Misra; Pralay Maiti; Biswa ..., Analytical Chemistry, 2016

Brominated graphene (GBR) with ∼3% bromine content has shown novel peroxidase mimetic activity toward 3,3′,5,5′-tetramethylbenzidine (TMB) in the presence of H2O2. Optimum activity has been observed at pH 4.48 and after a minimum ∼30 min of equilibration time. Among the different analytes studied ...
