A series of nineteen 2-aryl-4H-chromen-4-one derivatives 2a-2s were synthesized and
evaluated for their antiviral activity against Chikungunya virus (LR2006_OPY1) in Vero cell culture
by CPE reduction assay. Three compounds 2a, 2b and 2g, were found to be active at concentration of
(IC50) 0.44 M, 0.45 M and 2.02 M, respectively. Compounds having heterocyclic ring 2a and 2b
at the 2nd position of the chromenone were found to be potent inhibitor of ChikV. Cytotoxicity studies
were performed using Vero cell culture, compounds 2a and 2b exhibited SI of 100. Molecular
docking simulation has been carried out to understand the possible mechanism of action.
Treating the benzyl protected 3‐hydroxy‐1,3‐bis(2‐hydroxyphenyl)prop‐2‐en‐1‐ones solely with PhI(OAc)2 (PIDA) in DCE at room temperature readily furnished the seldom studied spiro‐2,2′‐benzo[b]furan‐3,3′‐ones in satisfactory to excellent yields. The hypervalent iodine reagent enables the metal‐free cascade spirocyclization resulting in the dual oxidative C−O bond formation.
solvent such as CH3CN. CLN1 provided a strong red-shifted absorption band in the visible region under alkaline conditions in water and upon the addition of TBAF in CH3CN. The absorption spectral study together with TD-DFT calculations and X-ray crystallographic analysis revealed that the characteristic π-resonant structures of CLN1 caused by the ionization or OH–F− interactions and the planar conformation

Abstract In the present scenario, the Synthesis of new and desired antimycobacterial agent has an eternal demand to resist Mycobacterium tuberculosis (MTB). The design and identification of new molecules for the treatment of tuberculosis is an important task in organic as well as medicinal chemistry research. In the present study, we have reported the combination of the desired compound using two versatile

This study was designed to synthesize and evaluate flavanone derivatives with phenylcarbamate moiety as potent acetylcholinesterase (AChE) inhibitors and anti-amnestic agents for management of AD. The synthesis of carbamate-substituted flavanone derivatives involved base-catalysed Claisen-Schmidt condensation reaction of 2-hydroxy acetophenone/2-hydroxy-4,6-dimethoxyacetophenone with differently substituted
