The synthesis of novel series of cyclopropane carbohydrazides is described via Knoevenagel condensationof 2-furfuraldehyde with malonic acid in five steps. Condensation of the key intermediate 2-(furan-2-yl)cyclopropanecarbohydrazide (4) with heteroaryl/aryl aldehydes (a-t) in presence of ZnO NP in ethanolresulted in substituted N- hetero/arylidene-2-(furan-2-yl) cyclopropane carbohydrazides (5a-t). These compoundswere screened for their anticancer activity against a panel of four cancer cell lines and four compoundsshowed promising activity at micromolar concentration against all the tested cell lines with IC50 values rangingbetween 1.9-8.45μM. These compounds were further validated with in silico methods at the anticancer target,colchicine binding site.
