Keywords: BINAP P Phos organophosphine oxide preparation potential antitumor agent.They researched the compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine( cas:221012-82-4 ).Product Details of 221012-82-4. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:221012-82-4) here.
Following previously reported pyridinyl phosphine oxides as antitumor agents, the com. available C2-axial chiral organophosphine ligand catalysts, such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) 1 and 2,2′,6,6′-tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine (P-Phos) 2 as a convenient source for producing organophosphine oxides were targeted as antitumor leads. Their corresponding chiral and racemic bi-phosphine oxides 3 and 4 can be obtained easily through a simple oxidation step with hydrogen peroxide, and their antitumor activities towards human hepatocellular carcinoma Hep3B cell line were reported. It was found that compound 3 shows stronger antitumor activity than that of 4, where axial chirality cannot improve their activity. Further athymic nude mice Hep3B xenograft model demonstrates the attractive in vivo antitumor potential of 3.
In some applications, this compound(221012-82-4)Product Details of 221012-82-4 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
