Abstract
A diverse set of 2 e- /2 H+ reactions are described that interconvert [RuII (bpy)(en*)2 ]2+ and [RuIV (bpy)(en-H*)2 ]2+ (bpy=2,2'-bipyridine, en*=H2 NCMe2 CMe2 NH2 , en*-H=H2 NCMe2 CMe2 NH- ), forming or cleaving different O-H, N-H, S-H, and C-H bonds. The reactions involve quinones, hydrazines, thiols, and 1,3-cyclohexadiene. These proton-coupled electron transfer reactions occur without substrate binding to the ruthenium center, but instead with precursor complex formation by hydrogen bonding. The free energies of the reactions vary over more than 90 kcal mol-1 , but the rates are more dependent on the type of X-H bond involved than the associated ΔG°. There is a kinetic preference for substrates that have the transferring hydrogen atoms in close proximity, such as ortho-tetrachlorobenzoquinone over its para-isomer and 1,3-cyclohexadiene over its 1,4-isomer, perhaps hinting at the potential for concerted 2 e- /2 H+ transfers.

Rapid in vivo detection of isoniazid-sensitive Mycobacterium tuberculosis by breath test. Nat Commun 2014; 5:4989.

Abstract
There is urgent need for rapid, point of care diagnostic tools for tuberculosis (TB) and drug sensitivity. Current methods based on in vitro growth take weeks, while DNA amplification can neither differentiate live from dead organisms nor determine phenotypic drug resistance. Here we show the development and evaluation of a rapid breath test for isoniazid (INH)-sensitive TB based on detection of labeled N2 gas formed specifically from labeled INH by mycobacterial KatG enzyme. In vitro data shows the assay is specific, dependent on mycobacterial abundance, and discriminates between INH-sensitive and resistant (S315T mutant KatG) TB. In vivo, the assay is rapid with maximal detection of 15N2 in exhaled breath of infected rabbits within five to ten minutes. No increase in 15N2 is detected in un-infected animals, and the increases in 15N2 are dependent on infection dose. This test may allow rapid detection of INH-sensitive TB.
