microwave-assisted method has been developed for the synthesis of tri-substituted pyrazoles via direct N-heterocyclization of hydrazines with metal-acetylacetonate and -dibenzylideneacetonate without using any base or additives. Most importantly, the synthesis of 1-aryl-5-phenyl-3-styryl-1H-pyrazoles was achieved in a single step using hydrochloride salt of various phenylhydrazines and this is the first

adenocarcinoma (HPAF) cells, as indicated by a decrease in the minimum neighbor distances of cells. Moreover, 25 inhibited cell colony formation in the non‐small‐cell lung cancercell line LXFA 526L in soft agar. Finally, 25 was observed to inhibit tumor growth in a murine xenograft model. Therefore, the novel specific compound 25 strengthens the hypothesis that SHP2 is a relevant protein target for the inhibition
