Synthesis, characterization and antiproliferative activity of hexa arm star shaped thiosemicarbazones derived from cyclotriphosphazene core

• Cyclotriphosphazene core based hexa arm star shaped thiosemicarbazones.
• 1H, 13C, 31P NMR, 2D HSQC spectral studies.
• Evaluation of in vitro antiproliferative activity against MCF7 and PA-1 cell lines.
• Structural activity correlationship.

A series of novel hexa-arm star shaped thiosemicarbazones with different substitutions at para positions emanating from cyclotriphosphazene core were prepared with excellent yields. The structure of all the synthesized compounds was confirmed by elemental analysis and spectroscopic methods (FT-IR, 1H, 13C, 31P NMR, 2D HSQC and ESI-MS). The compounds were evaluated for their in vitro antiproliferative activity against breast cancer (MCF7) and ovarian cancer (PA-1) cell lines using MTT assay. The newly synthesized compounds exhibited moderate to good activity against the tested cell lines. Among them the halo substituted benzoic thiosemicarbazones were found to be more potent towards anticancer activity.
