Three different series of some novel N-substituted rhodanines were designed for anticancer activity and prepared from the corresponding dithiocarbamates. The synthesized compounds were analyzed by IR, NMR and MASS to confirm their structures. All the titled compounds were found to be of Z configuration based on NMR spectral analysis. All the synthesized rhodanines were screened for in vitro anticancer activity against MCF-7 breast cancer cells at the concentration of 10µg. Compounds showed moderate to significant cytotoxicity. Amongst them, interestingly, compounds 10, 22 and 33 with cinnamoyl substitution at 5 th position of thiazolidine ring system showed significant activity. Further, we subjected all these compounds for the CoMSIA study to study their 3D quantitative structure activity relationships (3D QSAR). The illustration about the design of novel rhodanines, synthesis, analysis, activity against MCF-7 cells and SAR via CoMSIA study are reported here.
