Design, synthesis and analysis of Schiff based derivatives of Sulfadoxine drug and their metal complexes

Results in Chemistry
Sulfa drugs are the substituted pyrimidines containing anti-infective agents. The two novel Schiff base (SB) ligands were designed using sulfadoxine (Schiff base-1 (SB-1) ligand) and (Schiff base-2 (SB-2) ligand), computed, synthesized, and characterized.

Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.
