Acetic acid and propanoic acid were treated with thionyl chloride to give respective acid chlorides, which were then reacted with synthesized pyrazolines using triethylamine as catalyst in dry dichloromethane to give N-acetylated pyrazolines (1b-7b) and N-propanoylated pyrazolines (1c-7c). Synthesized N-substituted pyrazolines were characterized by IR, 1H NMR and 13C NMR spectral studies. Prepared compounds were screened for their microbial activity against Bacillus sp., Pseudomonas sp., Acinetobactor sp. and Klebsiella sp. N-acetylated (7b) and N-propanoylated (7c) pyrazolines having substitution of methoxy group at meta position and hydroxy group at para position of benzene ring were found effective against Bacillus sp., Acinetobactor sp. and Pseudomonas sp. but not against Klebsiella sp. All pyrazolines and N-substituted pyrazolines exhibited less activity than standard ampicillin at all the tested concentrations.

4-alkoxy-3-methoxyphenyl) was prepared, starting from 4-(4-hydroxy-3-methoxyphenyl)-3-buten-2-one, dehydrozingerone, and its alkyl derivatives. Their in vitro cytotoxic activity against some cancer cell lines was tested, showing significant anticanceractivity. All the new compounds were well characterized by IR, 1H, 13C NMR and ESI-MS spectroscopy and physical data, whereas structures of two of them were determined
