The bis‐cyclization of chalcone with thiosemicarbazide under basic condition led to the formation of new compounds, thiocarbamoyl bis‐pyrazoline derivatives. Bis‐chalcones were prepared by a Claisen–Schmidt condensation between 1 mol bis‐aldehyde and 2 mol acetophenone derivatives in the presence of sodium hydroxide as a catalyst. The structures of all compounds were elucidated by IR, 1H NMR, and 13C NMR spectral data and by elemental analyses.

In a wide search program towards new and efficient antimicrobial agents, a series of 40 substituted chalcones have been synthesized and tested for their in vitro antibacterial and antifungal activities. The structures of these compounds have been investigated by nuclear magnetic resonance spectroscopy and mass spectrometry. Among the (E)-4-aminoalkylthiochalcones and (E)-4-aminoalkoxychalcones tested, compounds 7, 10, 11, 30 and 31 have exhibited good antibacterial property against Staphylococcus aureus, Enterococcus faecalis and Bacillus subtilis.

Aspergillius janus, Aspergillus niger and Pencillium glabrum, respectively. The antimicrobial behaviour of the bispyrazolines 3a–3h is found to be dependent on the length of internal spacer unit. Synthesis and antimicrobial behaviour of the bispyrazolines built around the aliphatic chains have been described. The antimicrobial behaviour of these bisheterocyclic compounds is found to be dependent on the
