Abstract
The synthesized complexes, cis-[Ru(NO)(NO2)(phen)2](PF6)2 (NONO2P) and cis-[Ru(NO)(NO2)(bpy)2](PF6)2 (NONO2B), were characterized by using elemental analysis, voltammetry and electronic and vibrational spectroscopy. Under electrochemical and photochemical stimulation in an aqueous medium, there are indications of the formation of complexes, which suggests that the nitro and nitrosyl groups are converted into nitric oxide. Both compounds do not show cytotoxic activity against human umbilical vein endothelial cells (HUVECs). The cis-[Ru(NO)(NO2)(phen)2](PF6)2 complex presented vasorelaxation activity in superior mesenteric arteries from Wistar rats: the biphasic concentration-response curve indicates two sites of action. In the presence of NO scavengers, we observed an impaired relaxing effect induced by NONO2P, suggesting that the vasorelaxant effect is due to NO production from this compound.

Abstract
A series of half-sandwich iridium(III) benzimidazole-appended imidazolium-based N-heterocyclic carbene (NHC) antitumor complexes [(η5 -Cpx )Ir(C^N)Cl]Cl, where Cpx is pentamethylcyclopentadienyl (Cp*) or its biphenyl derivative (Cpxbiph ) and C^N is a NHC chelating ligand, were successfully synthesized and characterized. The IrIII complexes showed potential antitumor activity against A549 cells, at most three times more potent than cis-platin under the same conditions. Complexes could bind to BSA by a static quenching mode, catalyzing the change of NADH to NAD+ and inducing the production of reactive oxygen species (maximum turnover number, 9.8), which play an important role in regulating cell apoptosis. Confocal microscopy showed that the complexes could specifically target lysosomes in cells with a Pearson's co-localization coefficient 0.76 and 0.72 after 1 h and 6 h, respectively, followed an energy-dependent cellular uptake mechanism and damaged the integrity of lysosomes. At the same time, complexes caused a marked loss of mitochondrial membrane potential.

Abstract
![]()
Metallonitrosyl
complexes are promising as nitric oxide (NO) donors
for the treatment of cardiovascular, endothelial, and pathogenic diseases,
as well as cancer. Recently, the reduced form of NO– (protonated as HNO, nitroxyl, azanone, isoelectronic with O2) has also emerged as a candidate for therapeutic applications
including treatment of acute heart failure and alcoholism. Here, we
show that HNO is a product of the reaction of the RuII complex
[Ru(bpy)2(SO3)(NO)]+ (1) with glutathione or N-acetyl-L-cysteine, using met-myoglobin and carboxy-PTIO (2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide)
as trapping agents. Characteristic absorption spectroscopic profiles
for HNO reactions with met-myoglobin were obtained, as well as EPR
evidence from carboxy-PTIO experiments. Importantly, the product HNO
counteracted NO-induced as well as hypoxia-induced stabilization of
the tumor-suppressor HIF-1α in cancer cells. The functional
disruption of neovascularization by HNO produced by this metallonitrosyl
complex was demonstrated in an in vitro angiogenesis
model. This behavior is consistent with HNO biochemistry and contrasts
with NO-mediated stabilization of HIF-1α. Together, these results
demonstrate for the first time thiol-dependent production of HNO by
a ruthenium complex and subsequent destabilization of HIF-1α.
This work suggests that the complex warrants further investigation
as a promising antiangiogenesis agent for the treatment of cancer.
