A one pot transition metal free approach for geminal diarylation of pyrazolones has been accomplished. These diarylated pyrazolones are found to be neuroprotective and inhibitors of AChE.
molecular docking study has been carried to find out the interaction between active pyrazole compounds with 4FFW, 2CDU and IFJ4 (PDB id) indicated that compound P12, P4 and P10 showed good docking score with better potency within the ATP binding pocket respectively and may be used as a lead for rational drug designing of the novel molecules.To get more light on the regioselective synthesis of new hybrid

N-Aryl derivatives of edaravone were identified as potentially effective small molecule inhibitors of tau and beta-amyloid aggregation in the context of developing disease-modifying therapeutics for Alzheimer's disease (AD). Palladium-catalyzed hydrazine monoarylation protocols were then employed as an expedient means of preparing a focused library of 21 edaravone derivatives featuring varied N-aryl substitution, thereby enabling structure-activity relationship (SAR) studies. On the basis of data obtained from two functional biochemical assays examining the effect of edaravone derivatives on both fibril and oligomer formation, it was determined that derivatives featuring an N-biaryl motif were four-fold more potent than edaravone.

The P2Y(1) and P2Y(12) purinergic receptors are responsible for mediating adenosine diphosphate (ADP) dependent platelet aggregation. Evidence from P2Y(1) knockout studies as well as from nucleotide-based small molecule P2Y(1) antagonists has suggested that the antagonism of this receptor may offer a novel and effective method for the treatment of thrombotic disorders. Herein, we report the identification and optimization of a series of non-nucleotide P2Y(1) antagonists that are potent and orally bioavailable. (C) 2008 Elsevier Ltd. All rights reserved.
