Synthesis and Antioxidant Activity of Sterically Hindered Phenol Derivatives of Carboxy- and Sulfobetaines
摘要:
New multifunctional antioxidants based on carboxy- and sulfobetaines with sterically hindered phenol fragments were synthesized. The antioxidant capacity of the compounds determined in the reactions of their oxidation by electrogenerated bromine is comparable to that of ascorbic acid and ionol.
Delivery nanosystems based on sterically hindered phenol derivatives containing a quaternary ammonium moiety: Synthesis, cholinesterase inhibition and antioxidant activity
based on stericallyhinderedphenol and containing a quaternary ammonium moiety (SHP-n-Q) were synthesized. These compounds are inhibitors of cholinesterases with antioxidant properties. The inhibitory selectivity is 10-fold potent for BChE than for AChE. IC50 of SHP-n-Q for BChE is 20 μM. SHP-n-Q and their nanosystems exhibit more pronounced antioxidant properties than the synthetic antioxidant (hindered

Here, we present an approach to novel “hybrid” biologically active compounds based on a combination of stericallyhindered phenol and ammonium pharmacophores in a single molecule. The novel target ammonium salts were obtained by the reaction of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)-N-(2-(dimethylamino)alkyl)propanamide with aliphatic bromides or by the reaction of phosphorylated methylenequinones with
