Porous Polymer Bearing Polyphenolic Organic Building Units as a Chemotherapeutic Agent for Cancer Treatment

[Image: see text] Cancer is one of the most deadly diseases worldwide. Although several chemotherapeutic agents are available at present for its treatment, they have their own limitations. The main problems of these chemotherapeutic agents are cost involvement and severe life-threatening antagonistic effects. Here, we report a new biodegradable N-rich porous organic polymer methylenedianiline-triformyl phloroglucinol (MDTFP-1) synthesized via a Schiff base condensation reaction between two reactive monomers, that is, 4,4′-methylenedianiline and 2,4,6-triformyl phloroglucinol under inert atmosphere. Because this porous polymer contains polyphenolic building units and has a high Brunauer–Emmett–Teller surface area (283 m(2) g(–1)), it has been explored in the anticancer activity using HCT 116, A549, and MIA PaCa-2 cell lines. We have carried out the flow cytometric assessment using Annexin-V-FITC/PI staining through the exposed level of phosphatidylserine in the outer membrane of cells with MDTFP-1-induced apoptosis. Our results suggested that apoptosis of cells have been enhanced in a time-dependent manner in the presence of this novel porous polymer.
