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 Seven synthesized analogs exhibited sub-micromolar activities, from which compound 63 (2-(tert-Butyl)-N-(4-fluorophenyl)-3-((2,4,4-trimethylpentan-2-yl)amino)-1H-imidazo[1,2-b]pyrazole-7-carboxamide) exerted the most significant potency with a remarkable HL-60 sensitivity (IC50 = 0.183 μM).
After consulting a lot of data, we found that this compound(1827-27-6)Reference of 5-Amino-2-fluoropyridine can be used in many types of reactions. And in most cases, this compound has more advantages.
