Popis: 1-Alkyl-1′- N - para -(ferrocenyl) benzoyl dipeptide esters 4 – 12 were prepared by coupling the alkyl ferrocenyl benzoic acids 1 – 3 to the dipeptide ethyl esters Gly- L -Ala(OEt), Gly- L -Leu(OEt) and Gly- L -Phe(OEt) using the standard N -(3-dimethylaminopropyl)- N’ -ethylcarbodiimide hydrochloride (EDC), 1-hydroxybenzotriazole (HOBt) protocol. All the compounds were fully characterized using a combination of 1 H NMR, 13 C NMR, DEPT-135 and 1 H– 13 C COSY (HMQC) spectroscopy, electrospray ionization mass spectrometry (ESI-MS) and cyclic voltammetry (CV). Selected compounds showed micromolar activity in the H1299 NSCLC cell line, with IC 50 values in the range of 4.5–6.6 μM.
