malignant tumor cells and association with cancer invasion, metastasis and angiogenesis. Herein we describe the synthesis, biological evaluation, and structure–activity relationship study of two new series of pyrazoline analogues as APN inhibitors. Among these compounds, 5‐(2‐(2‐(hydroxyamino)‐2‐oxoethoxy)phenyl)‐3‐phenyl‐4,5‐dihydro‐1H‐pyrazole‐1‐carboxamide (compound 13 e) showed the best APN inhibition

Four new series of aromatic sulfamates were synthesized and investigated for the inhibition of four human (h) isoforms of zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), hCA I, II, IX, and XII. The reported derivatives, obtained by a sulfamoylation reaction of the corresponding phenolic precursors, bear 3,5-diarylpyrazoline moieties as spacers between the benzenesulfamate fragment which binds the
Twenty-five new hydroxyand methoxy-substituted 4,6-diarylpyrimidin-2(1H)-ol (20–34) and 4,6-diarylpyrimidine-2(1H)-thiol derivatives (35–44) were synthesized from the reaction of the corresponding 1,3-diaryl-2-propene-1one compounds (1–19) with urea or thiourea using the solid-phase microwave method. All the new synthetic compounds (20–44) were evaluated with regard to their α -glucosidase activity
