[PMID: 39202997 PMCID: PMC11356963 DOI: 10.3390/molecules29163918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 08/08/2024] [Accepted: 08/09/2024] [Indexed: 09/03/2024] Open
Abstract
Photoactive N-hydroxysulfonamides photocaged with the (6-bromo-7-hydroxycoumarin-4-yl)methyl chromophore have been successfully synthesized, and the mechanisms of photodecomposition investigated for two of the compounds. Upon irradiation up to 97% of a diagnostic marker for (H)NO release, sulfinate was observed for the trifluoromethanesulfonamide system. In the absence of a species that reacts rapidly with (H)NO, (H)NO instead reacts with the carbocation intermediate to ultimately generate (E)-BHC-oxime and (Z)-BHC-oxime. Alternatively, the carbocation intermediate reacts with solvent water to give a diol. Deprotonation of the N(H) proton is required for HNO generation via concerted C-O/N-S bond cleavage, whereas the protonation state of the O(H) does not affect the observed photoproducts. If the N(H) is protonated, C-O bond cleavage to generate the parent N-hydroxysulfonamide will occur, and/or O-N bond cleavage to generate a sulfonamide. The undesired competing O-N bond cleavage pathway increases when the volume percentage of water in acetonitrile/water solvent mixtures is increased.

Abstract
The emergence of nitroxyl (HNO) as a biological signaling molecule is attracting increasing attention. HNO-based prodrugs show considerable potential in treating congestive heart failure, with HNO reacting rapidly with metal centers and protein-bound and free thiols. A new class of 2-(2-nitrophenyl)ethyl (2-NPE)-photocaged N-hydroxysulfonamides has been developed, and the mechanisms of photodecomposition have been investigated. Three photodecomposition pathways are observed: the desired concomitant C-O/N-S bond cleavage to generate HNO, sulfinate, and 2-nitrostyrene, C-O bond cleavage to give the parent sulfohydroxamic acid and 2-nitrostyrene, and O-N bond cleavage to release a sulfonamide and 2-nitrophenylacetaldehyde. Laser flash photolysis experiments provide support for a Norrish type II mechanism involving 1,5-hydrogen atom abstraction to generate an aci-nitro species. A mechanism is proposed in which the (Z)-aci-nitro intermediate undergoes either C-O bond cleavage to release RSO2NHO(H), concerted C-O/N-S bond cleavage to generate sulfinate and HNO, or isomerization to the (E)-isomer prior to O-N bond cleavage. The pKa of the N(H) of the N-hydroxysulfonamide plays a key role in determining whether C-O or concerted C-O/N-S bond cleavage occurs. Deprotonating this site favors the desired C-O/N-S bond cleavage at the expense of an increased level of undesired O-N bond cleavage. Triplet state quenchers have no effect on the observed photoproducts.

Abstract
Nitric oxide (NO) serves as a key regulator of many physiological processes and as a potent therapeutic agent. The local delivery of NO is important to achieve target therapeutic outcomes due to the toxicity of NO at high concentrations. Although light stimulus represents a non-invasive tool with spatiotemporal precision to mediate NO release, many photoresponsive NO-releasing molecules can only respond to ultraviolet (UV) or near-UV visible light with low penetration and high phototoxicity. We report that coumarin-based NO donors with maximal absorbances at 328 nm can be activated under (deep) red-light (630 or 700 nm) irradiation in the presence of palladium(II) tetraphenyltetrabenzoporphyrin, enabling stoichiometric and self-reporting NO release with a photolysis quantum yield of 8 % via photoredox catalysis. This NO-releasing platform with ciprofloxacin loading can eradicate Pseudomonas aeruginosa biofilm in vitro and treat cutaneous abscesses in vivo.

Abstract
N-hydroxybenzenesulfonamide (commonly known as Piloty's acid) is considered a major source for nitroxyl (HNO) species which has potential biological and medicinal applications. In the present study, the conformational preferences and chemical reactivity of Piloty's acid (PA) and its hydrazide analogue (benzenesulfonylhydrazide, BSH) were studied using spectroscopic and computational tools. Six stable conformations of each molecule were theoretically identified, and their structures were fully optimized at the DFT-B3LYP and MP2 levels. Both molecules in their most stable forms adopt the anti configuration with the NH bond of the secondary amine pointing away from the terminal hydroxyl and amine moieties in the acid and hydrazide molecules, respectively. Three stable gauche states facilitated by weak intramolecular interactions of the SO⋯HO and SO⋯HN types arise due to the internal rotation about the SN linkage. Reliable assignments of the vibrational modes and the calculated reaction coordinates support a two-step mechanistic pathway of the Piloty's acid dissociation leading to the production of the nitroxyl (HNO) intermediate with moderate transition state barriers. Frontier molecular orbitals distributions, molecular electrostatic potential maps and condensed Fukui functions analysis of the molecules were employed to elucidate the agility of PA to dissociate to produce HNO and the absence of such a dissociation of BSH that would produce diazene (N2H2).

Abstract
Nitroxyl (HNO), a one-electron reduction product of nitric oxide, demonstrates distinct biological and pharmacological activities. Here we designed a bioluminescent turn-on probe, HNO-8, that could be used to visualize HNO without the need for excitation light. HNO-8 was prepared by caging 2-hydroxyethyl luciferin with a triphenylphosphine unit, in which 2-hydroxyethyl luciferin as a novel substrate of firefly luciferase was characterized by stronger and more sustained bioluminescent signals than the most popular substrates of d-luciferin and 6'-aminoluciferin. In vitro experiments showed that HNO-8 could selectively respond to HNO generated from Angeli's salt(AS) in the range 1-50 μM, with a limit of detection of 0.196 μM. The probe was successfully applied for visualizing HNO in luciferase-transfected Huh7 cancer cells. We envision that HNO-8 could be used as a powerful bioluminescent sensor for researching HNO biological roles.

Induction of caveolin-3/eNOS complex by nitroxyl (HNO) ameliorates diabetic cardiomyopathy. Redox Biol 2020; 32:101493.

Abstract
Nitroxyl (HNO), one-electron reduced and protonated sibling of nitric oxide (NO), is a potential regulator of cardiovascular functions. It produces positive inotropic, lusitropic, myocardial anti-hypertrophic and vasodilator properties. Despite of these favorable actions, the significance and the possible mechanisms of HNO in diabetic hearts have yet to be fully elucidated. H9c2 cells or primary neonatal mouse cardiomyocytes were incubated with normal glucose (NG) or high glucose (HG). Male C57BL/6 mice received intraperitoneal injection of streptozotocin (STZ) to induce diabetes. Here, we demonstrated that the baseline fluorescence signals of HNO in H9c2 cells were reinforced by both HNO donor Angeli's salt (AS), and the mixture of hydrogen sulfide (H2S) donor sodium hydrogen sulfide (NaHS) and NO donor sodium nitroprusside (SNP), but decreased by HG. Pretreatment with AS significantly reduced HG-induced cell vitality injury, apoptosis, reactive oxygen species (ROS) generation, and hypertrophy in H9c2 cells. This effect was mediated by induction of caveolin-3 (Cav-3)/endothelial nitric oxide (NO) synthase (eNOS) complex. Disruption of Cav-3/eNOS by pharmacological manipulation or small interfering RNA (siRNA) abolished the protective effects of AS in HG-incubated H9c2 cells. In STZ-induced diabetic mice, administration of AS ameliorated the development of diabetic cardiomyopathy, as evidenced by improved cardiac function and reduced cardiac hypertrophy, apoptosis, oxidative stress and myocardial fibrosis without affecting hyperglycemia. This study shed light on how interaction of NO and H2S regulates cardiac pathology and provide new route to treat diabetic cardiomyopathy with HNO.

Abstract
NaYF4:Yb,Er upconversion nanoparticles (UCNPs) capped with long-chain carboxylic acid were synthesized and then conjugated with chitosan (CS) in the aid of N-hydroxysuccinimide. The resultant nanocompound was integrated with doxorubicin (DOX) and Roussin's black salt (RBS), a photosensitive nitric oxide (NO) donor to produce stimuli-responsive UCNPs(DOX)@CS-RBS nanospheres as nanocarriers for controllable drug delivery. On the one hand, the encapsulated UCNPs can efficiently absorb NIR photons and convert them into visible photons to trigger NO release. On the other hand, the entrapped DOX can be released at lowered pH from the swollen nanospheres caused by stretched oleoyl-CS chains under acidic conditions. The UCNPs(DOX)@CS-RBS nanospheres exhibit great therapeutic efficacy, which is attributable to the combination of NO and DOX releases based on NO dose-dependent mechanisms. This study highlights the controllable release of NO and DOX from the same nanocarriers and the synergistic therapeutic effect on tumors, which could give new insights into improving cancer nanotherapeutics. STATEMENT OF SIGNIFICANCE In this paper, core-shell structured UCNPs(DOX)@CS-RBS nanospheres have been designed and synthesized via a step-by-step procedure. The stimuli-responsive UCNPs(DOX)@CS-RBS nanospheres act as nanocarriers for controllable drug delivery towards cancer therapy. The encapsulated UCNPs can efficiently absorb NIR photons and convert them into visible light to trigger NO release. Meanwhile, the entrapped DOX can be released from the swollen nanospheres caused by stretched oleoyl-CS chains at lowered pH typical of intracellular environment. Synergistic cancer therapy will be achieved through the combination of NO and DOX releases based on NO dose-dependent mechanisms. This study provides new drug nanocarriers with high antitumor efficacy for synergistic cancer therapy.

Abstract
Hydrogen sulfide (H2S) is an important biomolecule, and responsive chemical tools for its delivery are needed. Here, we utilize the photocleavable o-nitrobenzyl group to unmask caged thiocarbamates and to access photoactivated H2S releasing molecules. These donors function by the initial release of carbonyl sulfide (COS), which is quickly hydrolyzed to H2S by carbonic anhydrase (CA). Our investigations demonstrate that o-nitrobenzyl-caged thiocarbamates can serve as a donor platform for the bio-orthogonal stimulated release of COS/H2S.

Abstract
Nitric oxide (NO) is a physiological signaling molecule, whose biological production is precisely regulated at the subcellular level. Here, we describe the design, synthesis, and evaluation of novel mitochondria-targeted NO releasers, Rol-DNB-mor and Rol-DNB-pyr, that are photocontrollable not only in the UV wavelength range but also in the biologically favorable visible wavelength range (530-590 nm). These caged NO compounds consist of a hindered nitrobenzene as the NO-releasing moiety and a rhodamine chromophore. Their NO-release properties were characterized by an electron spin resonance (ESR) spin trapping method and fluorometric analysis using NO probes, and their mitochondrial localization in live cells was confirmed by costaining. Furthermore, we demonstrated visible light control of mitochondrial fragmentation via activation of dynamin-related protein 1 (Drp1) by means of precisely controlled NO delivery into mitochondria of cultured HEK293 cells, utilizing Rol-DNB-pyr.

Abstract
Nitroxyl (HNO) reacts with thiols, and this reactivity requires the use of donors with 1-nitrosocyclohexyl acetate, pivalate, and trifluoroacetate, forming a new group. These acyloxy nitroso compounds inhibit glyceraldehyde 3-phosphate dehydrogenase (GAPDH) by forming a reduction reversible active site disulfide and a reduction irreversible sulfinic acid or sulfinamide modification at Cys244. Addition of these acyloxy nitroso compounds to AhpC C165S yields a sulfinic acid and sulfinamide modification. A potential mechanism for these transformations includes nucleophilic addition of the protein thiol to a nitroso compound to yield an N-hydroxysulfenamide, which reacts with thiol to give disulfide or rearranges to sulfinamides. Known HNO donors produce the unsubstituted protein sulfinamide as the major product, while the acetate and pivalate give substituted sulfinamides that hydrolyze to sulfinic acids. These results suggest that nitroso compounds form a general class of thiol-modifying compounds, allowing their further exploration.

Abstract
Nitroxyl (HNO) is a small molecule with various pharmacological effects, including cardioprotective action. It is thought to serve as a modulator of various biochemical pathways. But, it is difficult to apply HNO directly for biological experiments or therapeutic treatment because it is highly reactive, readily dimerizing or reacting with biological targets under ambient conditions. Therefore, HNO donor molecules that release HNO under physiological conditions, especially those that allow precisely controllable release, would be useful to study the activities of HNO at the cellular level. This short review focuses on recently developed photocontrollable HNO-releasing compounds, which are expected to be suitable for achieving site-specific and temporally controlled HNO release in biomedical investigations. An illustrative application for the study of HNO-mediated upregulation of calcitonin gene-related peptide (CGRP) in A549 cells is described.
