Abstract:
:A number of bis(diazeniumdiolates) that we designed to release up to 4 mol of nitric oxide (NO) and that are structural analogues of the NO prodrug and anticancer lead compound O(2)-{2,4-dinitro-5-[4-(N-methylamino)benzoyloxy]phenyl} 1-(N,N-dimethylamino)diazen-1-ium-1,2- diolate (PABA/NO) were synthesized and studied. A majority of these compounds yielded higher levels of NO, were better inhibitors of proliferation of a number of cancer cell lines, and more rapidly induced substantially increased levels of S-glutathionylation of cellular proteins in comparison with PABA/NO. In most cases, the antiproliferative activity and extents of S-glutathionylation correlated well with levels of intracellular NO release. We report bis(diazeniumdiolates) to be a class of S-glutathionylating agents with potent antiproliferative and S-glutathionylating activity.
