Design And Synthesis Of Coumarin Derivatives Association With Pyrazoline For Anticancer Activity

Abstract

3-Acetyl-2H-chromen-2one (I) was created via Knoevenagel condensation of salicyladehyde with ethylacetoacetate in the presence of pipridine. Pyrazoline derivatives are utilised as possible therapeutic agents.  3-[(2E)-3-substituted-prop-2-enoyl] in succession Claisen-Schmidt condensation of 3-acetyl coumarin with aromatic aldehydes produced -2H-chromen-2-one derivatives (II a-h). When 3-substituted cinnamoylcoumarin was treated with hydrazine hydrate while ethanol was present, [5-substitutedphenyl] was produced.5 dihydro-1H-pyrazol-3-yl [-4, 5]III a-h, or -2H-chromen-2-one.  Both conventional and microwave-assisted methods were used to synthesise the title chemical. FT-IR, 1H & 13C NMR, LC-MS, and elemental analysis were used to characterise all of the synthesised compounds. The in vitro MTT assay was used to screen for anticancer activity against the Hos, HT 29, G 361, A 549, and DU 145 cell lines. It was discovered that all of the compounds had superior activity against the human skin cancer cell line G 361 and the bone cancer cell line Hos.
