DPPH Scavenging Assay of Novel 1,3-disubstituted-1H-pyrazol-5-ols and their in silico Studies on Some Proteins Involved in Alzheimer's Disease Signaling Cascade

A series of new 1,3-disubstituted-1H-pyrazol-5-ols (3) which are the analogues of known radical scavenger ‘edaravone’ are synthesized, characterized and evaluated for DPPH scavenging capacity. The docking studies are carried out for these compounds in the enol form and also in the respective keto form against the proteins and peptides involved in Alzhemier disease signal cascade. Some of them showed good radical scavenging capacity and molecular binding.
