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 analogues exhibited sub-micromolar activities, from which compound 63 exerted the most significant potency with a remarkable HL-60 sensitivity (IC50 = 0.183 μM).
Utility of cyanoacetamides as precursors to pyrazolo-[3,4-d]pyrimidin-4-ones, 2-aryl-6-substituted 1,2,3-triazolo-[4,5-d]pyrimidines and pyrazolo[1,5-a]pyrimidine-3-carboxamides

Cyanoacetamides (7a-c) were prepared via reacting cyanoacetic acid (5) with amines in the presence of acetic anhydride. Compounds (7a-c) coupled with benzenediazonium chloride to yield the phenylhydrazones (8a-c). These reacted with chloroacetonitrile to yield aminopyrazolecarboxamides (11a-c). Reaction of (8a,b) with hydroxylamine hydrochloride in DMF in presence of anhydrous sodium acetate afforded the amino-1,2,3-triazolecarboxamides (36a,b). Also compounds (7a-c) reacted with dimethylformamide dimethylacetal (DMFDMA) to yield the enamines (9a-c) which react with hydrazine hydrate to afford the aminopyrazoles (16a-c). Compounds (16) and (36) reacted with DMFDMA to yield the title heterocyclic derivatives.

The estrogen-related receptor α (ERRα) is an orphan receptor belonging to the nuclear receptor superfamily. The physiological role of ERRα has yet to be established primarily because of lack of a natural ligand. Herein, we describe the discovery of the fi
