Synthesis and Preliminary Cancer Cell Line Results for the Product of Organotin Dihalides and Alpha-Cyano-4-Hydroxycinnamic Acid

High polymer poly(ester ethers) are rapidly synthesized in good yield employing the interfacial polycondensation reaction system. Infrared spectroscopy shows the formation of new bands derived from the Sn–O and Sn–O(CO) linkages. It also shows that the products exist as alternating Sn–O and Sn–O(CO) linkages. MALDI MS shows formation of ion fragment clusters several units in length. The products show reasonable inhibition of a variety of cancer cell lines including two pancreatic cancer cell lines.
