4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is an organic compound with the formula (C 5 H 4 N) 2. It is one of several isomers of bipyridine. It is a colorless solid that is soluble in organic solvents. is mainly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C 5 H 4 NCH 3) 2] 2+, known as paraquat.
Bipyridines are a family of organic compounds with the formula (C 5 H 4 N) 2, consisting of two pyridyl (C 5 H 4 N) rings. Pyridine is an aromatic nitrogen-containing heterocycle. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. Bipyridines, especially the 4,4' isomer, are mainly of ...
Radical dimerization of pyridine with elemental sodium or Raney nickel selectively yields 4,4'-bipyridine, [98] or 2,2'-bipyridine, [99] which are important precursor reagents in the chemical industry. One of the name reactions involving free radicals is the Minisci reaction.
Paraquat (trivial name; / ˈ p ær ə k w ɒ t /), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is a toxic organic compound with the chemical formula [(C 6 H 7 N) 2]Cl 2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. [5]
Its basic research programs include chemical carcinogenesis; molecular, cellular, and structural biology; and translational research in novel therapies. It is known for its work in the study of lymphoma, [citation needed] and Eppley's notability in the field of transplantation began with bone marrow transplantation in 1983. [4] The Cancer ...
UW Carbone is a matrix cancer center, [2] allowing it to extend its influence through multiple departments and schools on the University of Wisconsin-Madison campus. UW Carbone unites physicians and scientists who work together in translating discoveries from research laboratories into new treatments that benefit cancer patients; the center conducts research, provides treatment and offers ...
Prevention is a key component of addressing the impact of head and neck cancer. Research from a recent pooled analysis suggests that drinking certain amounts of coffee or tea could decrease the ...
Some of these include the administration of cancer research programs, training activities, core facilities with technology shared by investigators, and clinical trial management services. [2] In 2015, more than 353,000 new patients were enrolled in a clinical trial at an NCI-designated Cancer Center. [4]
