Published in 2020 at "Archiv der Pharmazie"

DOI: 10.1002/ardp.202000074

Abstract: Novel Val–Val dipeptide–benzenesulfonamide conjugates were reported in this study. These were achieved by a condensation reaction of p‐substituted benzenesulfonamoyl alkanamides with 2‐amino‐4‐methyl‐N‐substituted phenyl butanamide using classical peptide‐coupling reagents. The compounds were characterized using Fourier transform… read more here.

Published in 2021 at "Behavioural Brain Research"

DOI: 10.1016/j.bbr.2020.113081

Abstract: BACKGROUND Previous studies suggest that genetic polymorphisms and aging modulate inter-individual variability in brain stimulation-induced plasticity. However, the relationship between genetic polymorphisms and behavioral modulation through transcranial direct current stimulation (tDCS) in older adults remains… read more here.
