Design, synthesis and biological activities of pyrrole-3-carboxamide derivatives as EZH2 (enhancer of zeste homologue 2) inhibitors and anticancer agents
Zeste enhancer homolog 2 (EZH2) is highly expressed in various malignant tumors, which could silence tumor suppressor genes via trimethylation of H3K27. Herein was first reported a novel series of pyrrole-3-carboxamide derivatives carrying a pyridone fragment as EZH2 inhibitors. By combining computational modeling, in vitro cellular assays and further rational structure–activity relationship exploration

An efficient method for the preparation of β-amino-α,β-unsaturated carbonylcompounds is demonstrated. Bench-stable sodium 3-oxo-enolates were prepared from carbonylcompounds, and reacted with amines in the presence of an acid and a desiccant. DFT studies revealed contrasting mechanisms toward the reactivity of aliphatic amines in protic solvents and aromatic amines in aprotic solvents. While the

An easy and efficient route for synthesis of some pyrimido[1,6‐a]pyrimidine and pyrazolo[1,5‐a]pyrimidine derivatives was described through the reaction of sodium salts of formyl ketones with 6‐aminothiouracil and 5‐aminopyrazole derivatives, respectively. The characterization of the reaction products was confirmed by using elemental analysis and spectral data. J. Heterocyclic Chem., (2012).
