Novel 1-substituted 3-(p-isopropylphenyl)-5-phenylformazans (3a–g) were synthesized and characterized by elemental analysis, 1H NMR, and FT-IR techniques and UV-visible spectroscopy. Antiproliferative activities of 3a–g against HeLa and C6 cells were determined using the BrdU cell proliferation ELISA assay. 5-Florouracil was used as the positive control. The effects of substituents (–H, –CH3, and –I) and their positions (ortho, meta, and para) on the antiproliferative activities were evaluated.
