  A series of substituted pyrazolo[1,5-a]pyrazin-4(5H)-one was synthesized by the reaction of ethyl 1-(2-oxo-2-phenylethyl)-3-phenyl-1H-pyrazole-5-carboxylate derivatives and 2-(2-aminoethoxy) ethanol or 2-morpholinoethanamine in the condition of microwave-assisted one-step and solvent-free in a good yield. The structures of the compounds were determined by IR, (1)H NMR and mass spectroscopy. In addition, a representative single-crystal structure was characterized by using X-ray diffraction analysis. Preliminary biological evaluation showed that the compounds could inhibit the growth of A549 and H322 cells in dosage-dependent manners. (C) 2011 Elsevier Ltd. All rights reserved.

  A series of novel oxime-containing pyrazole derivatives were synthesized by the reaction of ethyl 3-phenyl-1H-pyrazole-5-carboxylate derivatives and 2-bromo-1-phenylethanone followed by the reaction with hydroxylamine hydrochloride. The structures were determined by IR, (1)H NMR, HRMS, and X-ray analysis. A dose-and time-dependent inhibition of proliferation was observed in A549 lung cancer cell after compound treatment. Inhibition of growth was mainly attributed to the autophagy induction. (C) 2010 Elsevier Ltd. All rights reserved.

  A series of fluorescent compounds, containing pyrazolo[1,5-a]pyrazin-4(5H)-one moiety, were designed and synthesized from ethyl 1-(2-oxo-2-phenylethyl)-3-phenyl-1H-pyrazole-5-carboxylates. The structures of the compounds have been confirmed by IR, (1)H NMR, HRMS and X-ray crystal diffraction. The optical properties of the compounds were investigated by UV-vis absorption and fluorescence spectroscopy. The effect of pH on the UV-vis absorption of compound 2a in methanol-H(2)O solutions was studied and interpreted by theory calculation. The pK(a), value of compound 2a was determined by the absorption spectra. (C) 2011 Elsevier B.V. All rights reserved.
