To discover anticancer drugs with novel structures and expand our research scope, pyrazoline derivatives (-) were designed and synthesized through cyclization of chalcones with thiosemicarbazide/semicarbazide in CHCOOH as a solvent. All newly synthesized pyrazoline derivatives were fully characterized using several spectroscopic experiments such as H, C NMR, FT-IR spectroscopy, and mass analysis. By , the purity of all analogs was found above and both lead compounds ( and ) were also validated by .

The structural elucidation of N-formyl pyrazoline derivatives was carried out by various spectroscopic techniques such as H, C NMR, FT-IR, UV-visible spectroscopy, mass spectrometry and elemental analysis. Anticancer activity of the pyrazoline derivatives (3a-3l) was evaluated against human lung cancer (A549), fibrosarcoma cell lines (HT1080) and human primary normal lung cells (HFL-1) by MTT assay.
