In vitro, the cytotoxic effects of compounds 5–10 show improvements over the corresponding N-(ferrocenyl)benzoyl derivatives, with IC50 values against the H1299 lung cancer cells ranging from 1.2 μM to 8.0 μM. N-(6-ferrocenyl-2-naphthoyl)-glycine-l-alanine ethyl ester 8 was found to be the most active derivative of the naphthoyl series so far, displaying an IC50 value
