Lead derivatives of 2-cyclohexyl-N-[(Z)-(3-methoxyphenyl/3-hydroxyphenyl) methylidene]hydrazinecarbothioamides 1–18 were synthesized, characterized and evaluated in vitro against HER-2 overexpressed breast cancer cell line SKBr-3. All the compounds showed activity against HER-2 overexpressed SKBr-3 cells with IC50 = 17.44 ± 0.01 µM to 53.29 ± 0.33 µM. (2Z)-2-(3-Hydroxybenzylidene)-N-(3-methoxyphenyl)hydrazinecarbothioamide (12, IC50 = 17.44 ± 0.01 µM) was found to be most potent compound of this series targeting HER-2 overexpressed breast cancer cells compared to the standard drug 5-fluorouracil (5-FU) (IC50 = 38.58 ± 0.04 µM). Compound 12 inhibited the cellular proliferation via DNA degradation.
