A new series of resveratrol acrylamides amine derivatives was designed, synthesized, and evaluated for their anti-proliferative activity against three cancer cell lines including human chronic myelocytic leukemia cell K562, human hepatoma HuH-7 and human lung carcinoma A549. Most of the compounds showed superior activity against three cell lines when compared to parent resveratrol. C13 had the best anti-tumor activity against the HuH-7 cell line and its IC50 was 4.5 μmol/L; C16 had the best anti-tumor activity against the K562 cell line and its IC50 was 2.9 μmol/L; C18 had the best anti-tumor activity against the A549 cell line and its IC50 was 3.8 μmol/L. It could be seen that the activity of the aromatic amine derivatives was better than the fatty amine derivatives by analyzing the experimental data.

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 one-pot procedure was developed for the synthesis of novel 3-[amino(methoxy)methylene]-2-oxo-3,4-dihydro-2H-chromen-4-yl)-3-cyanoacetamides and chromeno[3,4-c]pyridine-1-carbonitriles from the reaction of 2-oxo-2H-chromene-3-carbonitriles and cyanoacetamides. These chromenederivatives were identified as new scaffolds for adenosine receptors and the hits 3a, 3c, 5a, and 5b were found.

The reaction of cyanothioacrylamides with dimethyl acetylenedicarboxylate, methylpropiolate, and N-phenylmaleimide was studied. The reaction follows a cycloaddition pathway to give thiopyrans, irrespective of the electronic or spatial effects of the substituents in the thioamide group and in position 3 of the 1-thiabuta-1,3-diene system. The reaction is regio-and stereoselective.
