Design, synthesis and characterization of novel functional polyesters containing chromone curcumin units and evaluation of its anticancer potential-An in vitro and in silico approach

A series of six novel polyesters (P1-P6) were obtained via by direct polycondenzation with hydroxyl functional-appended chromone and curcumin based monomers (M1, M2 and M3) were synthesized and subjected to thermogravimetric and spectroscopic analyses for structural characterization. The synthesized polymers were soluble common organic solvent such as DMF, THF, DMAc and 1-methyl-2-pyrrolidinone (NMP). The molecular weight of the polymers was found to be ranged from 3.390 × 105 – 1.1 × 105 g/mol by GPC-MALS. X-ray diffraction pattern of polyesters indicates P1, P2 and P3 are amorphous in nature, whereas polymer P4, P5, and P6 shows crystalline nature. The receptor VEGFR2 kinase can expand the synthesized molecules into 2D and 3D supramolecular networking through π-π stacking, hydrophobic, and H-bonding interactions. The cell viability effects of polymers on the growth of cell lines A549, HeLa and VERO were evaluated in vitro by MTT assay. The polymer P3 displayed potent anticancer activity compared to the other polymers. Research is undergone in developing curcumin chromone functional polymer as a workable biopolymer which could find value in the present findings.
