Molecular docking simulations were utilized to determine the binding affinities of five compounds produced. These compounds were IVa, IVb, IVc, IVd, and IVe. Chemicals derived from thiazolidin-4-one were designed to target cancer and human carbonic anhydrase IX (PDB code: 4M2V). These chemicals were designed to target humans. Our detailed sketching of the structure of the molecules was accomplished with the help of Chem Draw Ultra 12.0. To validate the compounds produced, the S. score and Rmsd values of the compounds were examined using the Molecular Operating Environment program. In contrast to acetazolamide, the proteins of the synthesized compounds had considerable binding affinities with the receptor active pocket, which suggested potential activity against cancer.
