A series of benzofuropyrazoles 2a—i were synthesized in 10—92% from the reaction of 2- aroylbenzofuran-3-ols 1a—i with hydrazine hydrate, and screened for their antitumor activities toward four human solid tumor cell lines, including gastric carcinoma cells MKN45, hepatocellular carcinoma cells HepG2, breast cancer cells MCF-7, and lung cancer cells A549.
