The synthesis and in vitro cytotoxic characteristics of new imidazo[1,2‐b]pyrazole‐7‐carboxamides were investigated. Following a hit‐to‐lead optimization exploiting 2D and 3D cultures of MCF‐7 human breast, 4T1 mammary gland, and HL‐60 human promyelocytic leukemia cancer cell lines, a 67‐membered library was constructed and the structure–activity relationship (SAR) was determined.

A three-component condensation of arylglyoxal hydrates, 5-amino-4-N-aryl-1H-pyrazole4-carboxamides, and barbituric acid furnished new 1H-imidazo[1,2-b]pyrazolederivatives. A similar condensation involving thiobarbituric acid leads to the organic salts of 2 : 1 bisadducts with 5-aminopyrazoles.
