The synthesis, structural characterization and in vitro anti-cancer activity of novel 1-alkyl-1′-N-para-(ferrocenyl) benzoyl dipeptide esters
摘要:
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 H-1 NMR, C-13 NMR, DEPT-135 and H-1-C-13 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 IC50 values in the range of 4.5-6.6 mu M. (C) 2014 Elsevier B. V. All rights reserved.
