The utilization of photodynamic therapy (PDT) for the treatment of various types of cancer has gained increasing attention over the last decades. Despite the clin. success of approved photosensitizers (PSs), their application is sometimes limited due to poor water solubility, aggregation, photodegradation, and slow clearance from the body. To overcome these drawbacks, research efforts are devoted toward the development of metal complexes and especially Ru(II) polypyridine complexes based on their attractive photophys. and biol. properties. Despite the recent research developments, the vast majority of complexes utilize blue or UV-A light to obtain a PDT effect, limiting the penetration depth inside tissues and, therefore, the possibility to treat deep-seated or large tumors. To circumvent these drawbacks, we present the first example of a DFT guided search for efficient PDT PSs with a substantial spectral red shift toward the biol. spectral window. Thanks to this design, we have unveiled a Ru(II) polypyridine complex that causes phototoxicity in the very low micromolar to nanomolar range at clin. relevant 595 nm, in monolayer cells as well as in 3D multicellular tumor spheroids.4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6SDS of cas: 1134-35-6) was used in this study.
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.SDS of cas: 1134-35-6 Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.
