Herein we report the synthesis of a new biomaterial designed for targeted delivery of poorly water-soluble inorganic anticancer drugs, with a focus on colorectal cancer. Diatomaceous earth microparticles derived from marine microalgae were coated with vitamin B12 (cyanocobalamin) as a tumor targeting agent and loaded with the well- known anticancer agents cisplatin, 5-fluorouracil (5-FU), and...

A series of tricarbonyl manganese complexes bearing 4-ethynyl-2,2′-bipyridine and 5- ethynyl-1,10-phenanthroline α-diimine ligands were synthetized, characterized and conjugated to vitamin B12, previously used as a vector for drug delivery, to take advantage of its water solubility and specificity toward cancer cells. The compounds act as photoactivatable carbon monoxide-releasing molecules...

The current photosensitizers (PSs) for photodynamic therapy (PDT) lack selectivity for cancer cells. To tackle this drawback, in view of selective cancer delivery, we envisioned conjugating two ruthenium polypyridyl complexes to vitamin B12 (Cobalamin, Cbl) to take advantage of the solubility and active uptake of the latter. Ultimately, our results showed that the transcobalamin pathway is...
