Biological evaluation of synthetic analogues of curcumin: chloro-substituted-2′-hydroxychalcones as potential inhibitors of tubulin polymerization and cell proliferation
A series of chloro-substituted-2'-hydroxychalcones were prepared and evaluated for their cytotoxic effects against K562 and SK-N-MC human cancer cell lines and as the inhibitors of tubulin polymerization. The 3,5'-dichloro- analogue (compound 3) inhibited the assembly of protofilaments with 89% inhibition. Compound 3 was found to be bound to tubulin with a dissociation constant of 3.7 mu M and altered far-UV circular dichroism spectrum of tubulin and altered far-UV circular dichroism spectrum of tubulin.
Multitarget 2′-hydroxychalcones as potential drugs for the treatment of neurodegenerative disorders and their comorbidities
mouse brain homogenates. Molecular modelling rationalised the binding mode of 2′-hydroxychalcones in the active site of hMAO-B. Additionally, several derivatives inhibited murine acetylcholinesterase (mAChE) (IC50 values from 4.37 ± 0.83 μM to 15.17 ± 6.03 μM) and reduced the aggregation propensity of Aβ. Moreover, some derivatives bound to the benzodiazepine binding site (BDZ-bs) of the γ-aminobutyric
