Figure 1: Molecular design and chemical structures. Legend (Left Panel) covalent immunochemotherapeutic, gemcitabine-(C4-amide)-[anti-HER2/ neu] synthesized utilizing a 2-stage organic chemistry reaction scheme that initially generates a gemcitabine UV-photoactivated intermediate; (Right Panel) griseofulvin capable of functioning as an alternative tubulin/microtubule inhibitor chemotherapeutic agent.
