Abstract
Selected rhodanine‐3‐carboxylic acids derivatives were synthesized to determine the influence of the structure and the length of the linker between the carboxyl group and the nitrogen atom (N‐3) in the 2‐thioxo‐4‐thiazolidinone ring on their activity, monitored via interactions with human serum albumin. Based on fluorescence studies, we concluded that the length of the linker has a limited impact on these interactions. Additionally, we proposed the static mechanism of quenching for all the tested compounds. These derivatives seem to possess an anticancer activity in the nanomolar range with 3 as the most potent compound in both A2780 and A2780cisR cell lines.
