Electric Literature of 92361-49-4, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II), molecular formula is C46H45ClP2Ru. In a patent, introducing its new discovery.
Background: In spite of significant progress made toward the synthesis of triazole amino acids as structural scaffolds of peptides and leading structures of new drugs, a need still exists for effective methods of trisubstituted triazole amino acid synthesis. Methods: A protocol based on ruthenium(II)-catalyzed alkyne-azide cycloaddition (RuAAC) was developed to synthesize 5-bromo-1,4,5-trisubstituted 1,2,3-triazole-based amino acid ? tert-butyl 5-bromo-1-(2-(1,3-dioxo-2,3dihydro-1H-isoindol-2-yl)ethyl]-1H-1,2,3-triazole-4-carboxylate (5Br-TzlAA). Two other disubstituted regioisomers, 1,4- and 1,5-TzlAA, were also synthesized to evaluate the influence of the 5-bromo substituent for triazole ring bioactivity. Results: Under optimal conditions, 5Br-TzlAA was synthesized within 1 h with 93% yield. NMR confirmed the structure of 5Br-TzlAA and showed regioselectivity of the RuAAC reaction. None of the TzlAAs were cytotoxic for the human cell lines investigated and showed a small pro-proliferatory effect at the highest concentrations (50-100 mug/mL) studied. A small anti-proliferative effect was visible for 1,4-TzlAA. Conclusion: A simple and effective protocol for the synthesis of 5-bromo-1,4,5-trisubstituted TzlAA (5Br-TzlAA) was developed. Bioassay results show that N-phthalimido modifying the TzlAAs are well tolerated by human cells and may be used as leading or scaffold structures to design new biologically active molecules.
