Functionalization of osmium arene anticancer complexes with (poly)arginine : effect on cellular uptake, internalization, and cytotoxicity [PDF]

open access: yes, 2011
Attaching peptides to metallodrugs may result in improved biological properties of the complexes. The potential use of cell penetrating peptides (CPPs) as cell delivery vectors is attractive, since directed cell uptake of (metallo)drugs remains a major ...

Structurally Simple Osmium(II) Polypyridyl Complexes as Photosensitizers for Photodynamic Therapy in the Near Infrared

open access: yes, 2022
Five osmium(II) polypyridyl complexes of the general formula [Os(4,7-diphenyl-1,10-phenanthroline)2L]2+ were synthesized as photosensitizers for photodynamic therapy by varying the nature of the ligand L.

Osmium-Catalyzed Asymmetric Dihydroxylation of Olefins by H2O2; Dual Role of the Cinchona Alkaloid Ligand

open access: yes, 2016
A novel application of the cinchona alkaloid derivative (DHQD)2PHAL in the osmium-catalyzed asymmetric dihydroxylation of olefins is presented. In a triple catalytic system using H2O2 as the terminal oxidant, the alkaloid ligand has a dual function in ...

New Osmium-Based Reagent for the Dihydroxylation of Alkenes

open access: yes, 2016
The cis dihydroxylation of alkenes is most efficiently accomplished by reaction with osmium tetroxide. Recently, the expense and toxicity of osmium tetroxide have led to a number of attempts to harness alternative osmium-based reagents, including ...
