Abstract
Caged compounds are frequently used in life science research. However, the light used to activate them is commonly absorbed and scattered by biological materials, limiting their use to basic research in cells or small animals. In contrast, hard X-rays exhibit high bio-permeability due to the difficulty of interacting with biological molecules. With the main goal of developing X-ray activatable caged compounds, azo compounds are designed and synthesized with a positive charge and long π-conjugated system to increase the reaction efficiency with hydrated electrons. The azo bonds in the designed compounds are selectively cleaved by X-ray, and the fluorescent substance Diethyl Rhodamine is released. Based on the results of experiments and quantum chemical calculations, azo bond cleavage is assumed to occur via a two-step process: a two-electron reduction of the azo bond followed by N─N bond cleavage. Cellular experiments also demonstrate that the azo bonds can be cleaved intracellularly. Thus, caged compounds that can be activated by an azo bond cleavage reaction promoted by X-ray are successfully generated.

Abstract
PURPOSE Neurogenic erectile dysfunction (ED) is a common side effect of radical prostatectomy (RP) because of cavernous nerve damage. In these patients, the production of nitric oxide (NO), which is important for erection, is decreased in the corpus cavernosum. Therefore, NO donors are useful for post-RP ED. However, short half-life and systemic side effects are problems of NO application in ED therapy. To avert these problems, we developed a red-light controllable NO releaser, NORD-1. This study aimed to investigate the effect of NORD-1 and red-light irradiation on neurogenic ED using a rat model of bilateral cavernous nerve injury (BCNI). MATERIALS AND METHODS BCNI and sham operations were conducted on 8-week-old rats. After 4 weeks, erectile function was evaluated using changes in intracavernous pressure (ICP) during electrostimulation of the cavernous nerve. ICP was measured under three conditions; without NORD-1 and red-light irradiation, with NORD-1 and without red-light irradiation, and with NORD-1 and red-light irradiation. SiR650 which absorbs red-light but does not release NO was used for the negative control. After the experiment, localization of NORD-1 was observed using a microscope. RESULTS Erectile function in a BCNI rat model was significantly decreased compared to sham-operated rats (p<0.05). After injecting NORD-1 into the penis, erectile function did not change without red-light irradiation. However, the combination of NORD-1 and red-light irradiation significantly improved erectile function (p<0.05) without affecting systemic arterial pressure. In contrast, when SiR650 was used, erectile function did not change in all three conditions. NORD-1 was detected only in the corpus cavernosum and not in the urethra and dorsal vein. CONCLUSIONS NORD-1 combined with red-light irradiation is effective for ED induced by cavernous nerve injury. This treatment may have low risks of hypotension and urinary incontinence, and it can replace the current treatment for post-RP ED.

Abstract
Caged compounds protected with photolabile protecting groups (PPGs) are useful for controlling various biological events with high spatiotemporal resolution. Most of the commonly used PPGs are controlled by ultraviolet light irradiation, but it is desirable to have PPGs controlled by visible light irradiation in order to minimize tissue damage. Here, we describe a boron-dipyrromethene (BODIPY)-picolinium conjugate (BPc group) that functions as a blue-light-controllable PPG. ESR experiments indicate that the photolysis mechanism is based on intramolecular photoinduced electron transfer. We illustrate the applicability of the BPc group to biologically active compounds by employing it firstly to photocontrol release of histamine, and secondly to photocontrol release of a soluble guanylyl cyclase (sGC) activator, GSK2181236A, which induces photovasodilation. The BPc group is expected to be a useful PPG for controlling various biological events with blue light irradiation.

Abstract
Nitric oxide (NO) is a signaling molecule that plays a variety of functions in the human body, but it is difficult to use it in biological experiments or for therapeutic purposes because of its high reactivity and instability in the biological milieu. Consequently, photocontrollable NO releasers, which enable spatiotemporal control of NO release, have an important role in elucidating the functions of NO. Our group has developed visible-light-controllable NO-releasing molecules that contain a fluorescent dye structure as a light-harvesting antenna moiety and an N-nitrosoaminophenol structure as an NO-releasing moiety. Here, we aimed to construct an NO-generating system employing an intermolecular photoredox reaction between the two separate components, since this would simplify chemical synthesis and make it easier to examine various dyes as antennae. For this purpose, we constructed polymer nanoparticles doped with both N-methyl-N-nitroso-4-aminophenol (NAP, 1) and an Ir(III) antenna complex (2, 3 or 4) in order to dissolve in aqueous solution without a co-solvent. These polymer nanoparticles released NO upon photoirradiation in vitro in the purple (400-430 nm) or blue (400-460 nm) wavelength region to activate the doped Ir(III) complex.

Abstract
We present an optochemical O2 scavenging system that enables precise spatiotemporal control of the level of hypoxia in living cells simply by adjusting the light intensity in the illuminated region. The system employs rhodamine containing a selenium or tellurium atom as an optochemical oxygen scavenger that rapidly consumes O2 by photochemical reaction with glutathione as a coreductant upon visible light irradiation (560-590 nm) and has a rapid response time, within a few minutes. The glutathione-consuming quantum yields of the system were calculated as about 5%. The spatiotemporal O2 consuming in cultured cells was visualized with a hypoxia-responsive fluorescence probe, MAR. Phosphorescence lifetime imaging was applied to confirmed that different light intensities could generate different levels of hypoxia. To illustrate the potential utility of this system for hypoxia research, we show that it can spatiotemporally control calcium ion (Ca2+) influx into HEK293T cells expressing the hypoxia-responsive Ca2+ channel TRPA1.

Abstract
Nitric oxide (NO) has multiple physiological activities, including roles in vasorelaxation, neurotransmission, and immune response. Indeed, NO-releasing compounds are utilized as therapeutic agents for cardiovascular diseases based on the potent and rapid vasorelaxation induced by NO. We have developed a series of photoinduced-electron-transfer-driven (PeT-driven) NO releasers composed of a light-harvesting antenna moiety and an NO-releasing N-nitrosoaminophenol moiety, which efficiently release NO upon irradiation with blue (500 nm), green (560 nm), or red (650 nm) light. In this paper, we investigated substituent effects at the 2-position of the N-nitrosoaminophenol moiety by means of spectroscopic, fluorescence, and NO-release measurements. Interestingly, a methyl substituent at this position had no significant effect on the NO-releasing ability, while a nitro group or a methoxy group reduced it. The nitro group may suppress electron transfer to the antenna moiety, while the methoxy group may accelerate electron transfer but suppress deprotonation to afford the phenoxyl radical, which is the key reaction for release of NO. These structure-activity relationships should be helpful for further functionalizing PeT-driven NO releasers.

Abstract
Fluorescence-guided cancer surgery can dramatically improve recurrence rates and postoperative quality of life of patients by accurately distinguishing the boundary between normal and cancer tissues during surgery, thereby minimizing excision of normal tissue. One promising target in early stage cancer is fragile histidine triad (FHIT), a cancer suppressor protein with dinucleoside triphosphate hydrolase activity. In this study, we have developed fluorescence probes containing a nucleoside diphosphate moiety, which dramatically improves the reactivity and specificity for FHIT, and a moderately lipophilic ester moiety to increase the membrane permeability. The ester moiety is cleaved by ubiquitous intracellular esterases, and then, FHIT in the cells specifically cleaves nucleoside monophosphate. The remaining phosphate moiety is rapidly cleaved by ubiquitous intracellular phosphatases to release the fluorescent dye. We confirmed that this probe can detect FHIT activity in living cells. A comprehensive evaluation of the effects of various ester moieties revealed that probes with CLogP = 5-7 showed good membrane permeability and were good substrates of the target enzyme; these findings may be helpful in the rational design of other multiple phosphate-containing probes targeting intracellular enzymes.

Abstract
We found that N-nitrosoaminoanisole derivatives tethered to dyes work as photocontrollable nitrosonium cation releasers and are converted to potent nitric oxide releasers in the presence of sodium ascorbate. The N-nitrosoaminoanisole derivative 2 worked as a more potent photovasodilating reagent ex vivo than previously reported nitric oxide releasers.

Abstract
We aimed to control the relaxation of rat bladder neck specimens by using NORD-1, a red light-reactive nitric oxide (NO) releaser. Female and male 10-11-week-old Wistar/ST rats were divided into three groups: NORD-1, vehicle, and NORD-1+[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; a soluble guanylyl cyclase inhibitor). We infused 10-4 M NORD-1 into the bladders of NORD-1 and NORD-1+ODQ group rats and the vehicle into those of vehicle group rats. Isometric tension was analyzed using circular bladder neck specimens with 10-5 M NG-nitro-l-arginine methyl ester, an NO synthase inhibitor. Moreover, 10-5 M ODQ was added into the NORD-1+ODQ group bath. After precontraction with 10-5 M carbachol, the specimens were irradiated with red light and their relaxation responses were measured. We evaluated NORD-1 tissue permeability by observing the sliced bladder neck specimens. The NORD-1 group specimens relaxed during red light irradiation; the relaxation response increased with the increase in light intensity. The vehicle and NORD-1+ODQ group specimens did not respond to irradiation. Sex-related differences in responsiveness were not noted. NORD-1 permeated into the urothelium of NORD-1 group specimens. Rat bladder neck relaxation was controlled by NORD-1 and light irradiation in vitro. NORD-1 might be a novel therapeutic agent for voiding dysfunction.

Abstract
For the early diagnosis of cancer, leading to a better chance of full recovery, marker genes whose expression is already altered in precancerous lesions are desirable, and the tumor-suppressor gene FHIT is one candidate. The gene product, FHIT protein, has a unique dinucleoside triphosphate hydrolase (AP3Aase) activity, and in this study, we designed and synthesized a series of FHIT fluorescent probes utilizing this activity. We optimized the probe structure for high and specific reactivity with FHIT and applied the optimized probe in a screening assay for FHIT inhibitors. Screening of a compound library with this assay identified several hits. Structural development of a hit compound afforded potent FHIT inhibitors. These inhibitors induce apoptosis in FHIT-expressing cancers via caspase activation. Our results support the idea that FHIT binders, no matter whether inhibitors or agonists of AP3Aase activity, might be promising anticancer agents.

Abstract
Human sirtuins (SIRT1-7) regulate not only deacetylation but also deacylation of fatty acid-derived acyl moieties (defatty-acylation) at the ε-amino group of lysine residues. SIRT-subtype-specific defatty-acylase activity modulators are needed for detailed investigation of the biological roles of these enzymes, and to find suitable small molecules, we require appropriate screening systems. Here, we designed and synthesized a set of SIRT defatty-acylase activity probes with various quencher moieties and peptide sequences based on our previously developed one-step FRET-based SIRT probe SFP3, using improved methodology. Scanning of this set of probes with SIRT isozymes revealed that certain probe/isozyme combinations showed especially high responses. To illustrate the utility of the combinations thus identified, we applied compound 18/SIRT2 for inhibitor screening of a large chemical library. This enabled us to discover a new small molecule SIRT2-specific defatty-acylase inhibitor.

Abstract
We designed and synthesized a novel Si-rhodamine derivative, NORD-1, as a red-light-controllable nitric oxide (NO) releaser, on the basis of photoredox parameter analysis. Red-light-responsive NO release from NORD-1 was confirmed by ESR spin trapping and quantified with an NO electrode and by means of Griess assay. The NO release cross section (ε656 nm·ΦNO) of NORD-1 was calculated to be 3.65 × 102, which is larger than that of a previously reported yellowish-green-light-controllable NO releaser, NO-Rosa5. The photoresponsiveness of NO release from NORD-1 was precise and efficient enough to induce vasodilation ex vivo under Magnus test conditions. Finally, we showed that intracavernous pressure (ICP) could be controlled in rats in vivo with the combination of NORD-1 and a red-light source without increasing systemic blood pressure, which is a serious side effect of usual NO releasers, such as nitroglycerin and isopentyl nitrite. NORD-1 is expected to be a useful chemical tool for NO research, as well as a candidate agent to control the circulatory system.

Abstract
Lysine methylation is one of the most important modification, which is regulated by histone lysine methyltransferases and histone lysine demethylases. Lysine-specific demethylase 1 (LSD1) specifically demethylates mono- and dimethyl-lysine on histone H3 (H3K4Me/Me2, H3K9Me/Me2) to control chromatin structure, resulting in transcriptional repression or activation of target genes. Furthermore, LSD1 is overexpressed in various cancers. Therefore, LSD1 inhibitors would be not only potential therapeutic agents for cancers but also chemical tools to research biological significance of LSD1 in physiological and pathological events. However, known assay methods to date have some inherent drawbacks. The development of simple method in detecting LSD1 activity has been indispensable to identify useful inhibitors. In this study, we designed and synthesized artificial substrates based on inhibitors of LSD1 to examine LSD1 activity by an absorption increment.

Abstract
One of the regulatory mechanisms of epigenetic gene expression is the post-translational methylation of arginine residues, which is catalyzed by protein arginine methyltransferases (PRMTs). Abnormal expression of PRMT4/CARM1, one of the PRMTs, is associated with various diseases, including cancers. Here, we designed and synthesized a Förster resonance energy transfer (FRET)-based probe, FRC, which contains coumarin and fluorescein fluorophores at the N-terminus and C-terminus of a peptide containing an arginine residue within an appropriate amino acid sequence to serve as a substrate of CARM1; the two fluorophores act as a FRET donor and a FRET acceptor, respectively. Since trypsin specifically hydrolyzes the arginine residue, but not a monomethylarginine or dimethylarginine residue, CARM1 activity can be evaluated from the change of the coumarin/fluorescein fluorescence ratio of FRC in the presence of trypsin.

Abstract
Peptidyl arginine deiminases (PADs) catalyze the post-translational deimination of arginine residues to citrulline residues. Aberrant levels of PAD activity are associated with various diseases, such as rheumatoid arthritis, Alzheimer's disease, and multiple sclerosis, so there is a need for simple and convenient high-throughput screening systems to discover PAD inhibitors as candidate therapeutic agents. Here, we report a highly sensitive off/on-type fluorescence probe for PAD activity based on the donor-excited photoinduced electron transfer (d-PeT) mechanism, utilizing the specific cycloaddition reaction between the benzil group of the probe and the ureido group of the PAD product, citrulline, under acidic conditions. We synthesized and functionally evaluated a series of probes bearing substituents on the benzil phenyl group, and found that 4MEBz-FluME could successfully detect citrulline with higher sensitivity and broader dynamic range than our previously reported fluorescence probe, FGME. Moreover, we succeeded in establishing multiple assay systems for PAD subtypes activities, including PAD2 and PAD4, with 4MeBz-FluME thanks to its high sensitivity. We expect that our fluorescence probes will become a powerful tool for discovering PAD inhibitors of several subtypes. Thus, it should be suitable for high-throughput screening of chemical libraries for inhibitors of PADs.

Abstract
Spatiotemporally controllable nitric oxide (NO) releasers are required for biological studies and as candidate therapeutic agents. Here, we investigate the structure-efficiency relationship of a series of photoinduced electron transfer-triggered NO releasers based on our reported yellowish-green light-controllable NO releaser, NO-Rosa. The distance between the NO-releasing N-nitrosoaminophenol moiety and the rosamine antenna moiety was critical for efficient NO release. Notably, substitution at the phenolic hydroxyl group blocked NO release. We synthesized NO-Rosa-Gal bearing D-galactose (Gal) at this location, and showed that hydrolysis by β-galactosidase restored the photoresponse. This represents proof-of-concept of a strategy for highly specific control of NO release by using a double-lock system involving both enzymatic reactivation and photo-control.

Abstract
Pin1 (protein interacting with never in mitosis A-1) is a member of the peptidyl prolyl isomerase (PPIase) family, and catalyzes cis-trans isomerization of pThr/Ser-Pro amide bonds. Because Pin1 is overexpressed in various cancer cell lines and promotes cell growth, it is considered a target for anticancer agents. Here, we designed and synthesized a covalently binding Pin1 inhibitor (S)-2 to target Pin1's active site. This compound inhibited Pin1 in protease-coupled assay, and formed a covalent bond with Cys113 of Pin1, as determined by ESI-MS. The acetoxymethyl ester of (S)-2, i.e., 6, suppressed cyclin D1 expression in human prostate cancer PC-3 cells, and exhibited cytotoxicity. Pin1-knockdown experiments indicated that a target for the cytotoxicity of 6 is Pin1.

Abstract
Nitric oxide (NO) has been known as a gaseous chemical mediator, which modulates several physiological functions. Spatial and temporal control of NO release facilitates further study and medical application of NO. Herein, we report design and synthesis of a novel NO donor, NO-Rosa. NO-Rosa has a rosamine moiety, which absorbs yellowish green light. Upon irradiation with yellowish green light (530-590 nm), NO is released from NO-Rosa, presumably via photoinduced electron transfer from the N-nitrosoaminophenol moiety to the rosamine moiety. NO release from NO-Rosa was detected by ESR spin trapping and a NO fluorescent probe. Cellular NO release control was achieved in HEK293 cells using a NO fluorescent probe, DAF-FM DA. Furthermore, temporally controlled NO-induced vasodilation was demonstrated by treatment of a rat aortic strip with NO-Rosaex vivo and irradiation by yellowish green light. NO-Rosa is expected to be utilized for further study of NO-related physiological functions, utilizing its ability of spatiotemporal release of NO as a photocontrollable compound with harmless yellowish-green light.

Abstract
Site-specific fluorescence probes can be used to measure distances within proteins when used as part of a Förster resonance energy transfer (FRET) pair. Here we report the synthesis of a coumarin maleimide (Mcm-Mal) that is fluorogenic upon reaction with cysteine. We demonstrate that cysteine, acridonylalanine (Acd) double mutant proteins can be produced by unnatural amino acid mutagenesis and reacted with Mcm-Mal to generate Mcm/Acd labeled proteins for FRET studies. The Mcm/Acd FRET pair is minimally-perturbing, easy to install, and well-suited to studying protein distances in the 15-40 Å range. Furthermore, Mcm/Acd labeling can be combined with tryptophan fluorescence in three color FRET to monitor multiple interactions in one experiment.

Abstract
Acridonylalanine (Acd) is a useful fluorophore for studying proteins by fluorescence spectroscopy, but it can potentially be improved by being made longer wavelength or brighter. Here, we report the synthesis of Acd core derivatives and their photophysical characterization. We also performed ab initio calculations of the absorption and emission spectra of Acd derivatives, which agree well with experimental measurements. The amino acid aminoacridonylalanine (Aad) was synthesized in forms appropriate for genetic incorporation and peptide synthesis. We show that Aad is a superior FRET acceptor to Acd in a peptide cleavage assay, and that Aad can be activated by an aminoacyl tRNA synthetase for genetic incorporation. Together, these results show that we can use computation to design enhanced Acd derivatives which can be used in peptides and proteins.

Abstract
Olfactory stimuli play an important role in regulating reproductive functions in mammals. The present study investigated the effect of olfactory signals derived from male rats on kisspeptin neuronal activity and luteinising hormone (LH) secretion in female rats. Wistar-Imamichi strain female rats were ovariectomised (OVX) and implanted with preovulatory levels of 17β-oestradiol (E2 ). OVX+E2 rats were killed 1 hour after exposure to either: clean bedding, female-soiled bedding or male-soiled bedding. Dual staining for Kiss1 mRNA in situ hybridisation and c-Fos immunohistochemistry revealed that the numbers of Kiss1-expressing cells and c-Fos-immunopositive Kiss1-expressing cells in the anteroventral periventricular nucleus (AVPV) were significantly higher in OVX+E2 rats exposed to male-soiled bedding than those of the other groups. No significant difference was found with respect to the number of c-Fos-immunopositive Kiss1-expressing cells in the arcuate nucleus and c-Fos-immunopositive Gnrh1-expressing cells between the groups. The number of c-Fos-immunopositive cells was also significantly higher in the limbic system consisting of several nuclei, such as the bed nucleus of the stria terminalis, the cortical amygdala and the medial amygdala, in OVX+E2 rats exposed to male-soiled bedding than the other groups. OVX+E2 rats exposed to male-soiled bedding showed apparent LH surges, and the peak of the LH surge and area under the curve of LH concentrations in the OVX+E2 group were significantly higher than those of the other two groups. These results suggest that olfactory signals derived from male rats activate AVPV kisspeptin neurones, likely via the limbic system, resulting in enhancement of the peak of the LH surge in female rats. Taken together, the results of the present study suggests that AVPV kisspeptin neurones are a target of olfactory signals to modulate LH release in female rats.

Abstract
Pulsatile secretion of gonadotrophin-releasing hormone (GnRH)/luteinising hormone is indispensable for the onset of puberty and reproductive activities at adulthood in mammalian species. A cohort of neurones expressing three neuropeptides, namely kisspeptin, encoded by the Kiss1 gene, neurokinin B (NKB) and dynorphin A, localised in the hypothalamic arcuate nucleus (ARC), so-called KNDy neurones, comprises a putative intrinsic source of the GnRH pulse generator. Synchronous activity among KNDy neurones is considered to be required for pulsatile GnRH secretion. It has been reported that gap junctions play a key role in synchronising electrical activity in the central nervous system. Thus, we hypothesised that gap junctions are involved in the synchronised activities of KNDy neurones, which is induced by NKB-NK3R signalling. We determined the role of NKB-NK3R signalling in Ca2+ oscillation (an indicator of neuronal activities) of KNDy neurones and its synchronisation mechanism among KNDy neurones. Senktide, a selective agonist for NK3R, increased the frequency of Ca2+ oscillations in cultured Kiss1-GFP cells collected from the mediobasal hypothalamus of the foetal Kiss1-green fluorescent protein (GFP) mice. The senktide-induced Ca2+ oscillations were synchronised in the Kiss1-GFP and neighbouring glial cells. Confocal microscopy analysis of these cells, which have shown synchronised Ca2+ oscillations, revealed close contacts between Kiss1-GFP cells, as well as between Kiss1-GFP cells and glial cells. Dye coupling experiments suggest cell-to-cell communication through gap junctions between Kiss1-GFP cells and neighbouring glial cells. Connexin-26 and -37 mRNA were found in isolated ARC Kiss1 cells taken from adult female Kiss1-GFP transgenic mice. Furthermore, 18β-glycyrrhetinic acids and mefloquine, which are gap junction inhibitors, attenuated senktide-induced Ca2+ oscillations in Kiss1-GFP cells. Taken together, these results suggest that NKB-NK3R signalling enhances synchronised activities among neighbouring KNDy neurones, and that both neurone-neurone and neurone-glia communications via gap junctions possibly contribute to synchronised activities among KNDy neurones.

Abstract
Sirtuins (SIRTs) are a family of NAD+‐dependent histone deacetylases. In mammals, dysfunction of SIRTs is associated with age‐related metabolic diseases and cancers, so SIRT modulators are considered attractive therapeutic targets. However, current screening methodologies are problematic, and no tools for imaging endogenous SIRT activity in living cells have been available until now. In this work we present a series of simple and highly sensitive new SIRT activity probes. Fluorescence of these probes is activated by SIRT‐mediated hydrolytic release of a 4‐(4‐dimethylaminophenylazo)benzoyl (Dabcyl)‐based FRET quencher moiety from the ϵ‐amino group of lysine in a nonapeptide derived from histone H3K9 and bearing a C‐terminal fluorophore. The probe SFP3 detected activities of SIRT1, ‐2, ‐3, and ‐6, which exhibit deacylase activities towards long‐chain fatty acyl groups. We then truncated the molecular structure of SFP3 in order to improve both its stability to peptidases and its membrane permeability, and developed probe KST‐F, which showed specificity for SIRT1 over SIRT2 and SIRT3. We show that KST‐F can visualize endogenous SIRT1 activity in living cells.

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
Purpose To investigate whether relaxation of the rat penile corpus cavernosum could be controlled with NOBL-1, a novel, light-controllable nitric oxide (NO) releaser. Materials and Methods Fifteen-week-old male Wistar-ST rats were used. The penile corpus cavernosum was prepared and used in an isometric tension study. After noradrenaline (10-5 M) achieved precontraction, the penile corpus cavernosum was irradiated by light (470–500 nm) with and without NOBL-1 (10-6 M). In addition, we noted rats' responses to light with vardenafil (10-6 M), a phosphodiesterase-5 (PDE-5) inhibitor. Next, responses to light in the presence of a guanylate cyclase inhibitor, ODQ (1H-[1,2,4] oxadiazolo[4,3-a]quinoxalin-1-one) (10-5 M), were measured. All measurements were performed in pretreated L-NAME (10-4 M) conditions to inhibit endogenous NO production. Results Corpus cavernosal smooth muscle, precontracted with noradrenaline, was unchanged by light irradiation in the absence of NOBL-1. However, in the presence of NOBL-1, corpus cavernosal smooth muscle, precontracted with noradrenaline, relaxed in response to light irradiation. After blue light irradiation ceased, tension returned. In addition, the light response was obviously enhanced in the presence of a PDE-5 inhibitor. Conclusions This study showed that rat corpus cavernosal smooth muscle relaxation can be light-controlled using NOBL-1, a novel, light sensitive NO releaser. Though further in vivo studies are needed to investigate possible usefulness, NOBL-1 may be prove to be a useful tool for erectile dysfunction therapy, specifically in the field of penile rehabilitation.

Abstract
Pin1 is a peptidyl prolyl isomerase that specifically catalyzes cis-trans isomerization of phosphorylated Thr/Ser-Pro peptide bonds in substrate proteins and peptides. Pin1 is involved in many important cellular processes, including cancer progression, so it is a potential target of cancer therapy. We designed and synthesized a novel series of Pin1 inhibitors based on a glutamic acid or aspartic acid scaffold bearing an aromatic moiety to provide a hydrophobic surface and a cyclic aliphatic amine moiety with affinity for the proline-binding site of Pin1. Glutamic acid derivatives bearing cycloalkylamino and phenylthiazole groups showed potent Pin1-inhibitory activity comparable with that of known inhibitor VER-1. The results indicate that steric interaction of the cyclic alkyl amine moiety with binding site residues plays a key role in enhancing Pin1-inhibitory activity.

Abstract
Photocontrollable NO donors enable precise spatiotemporal release of NO under physiological conditions. We designed and synthesized a novel dimethylnitrobenzene-type NO donor, Flu-DNB-DB, which contains a carbon-carbon double bond in place of the amide bond of previously reported Flu-DNB. Flu-DNB-DB releases NO in response to one-photon activation in the blue wavelength region, and shows a greatly increased two-photon cross-section (δu) at 720 nm (Flu-DNB: 0.12 GM, Flu-DNB-DB: 0.98 GM). We show that Flu-DNB-DB enables precisely controlled intracellular release of NO in response to 950 nm pulse laser irradiation for as little as 1s. This near-infrared-light-controllable NO source should be a valuable tool for studies on the biological roles of NO.

Abstract
The levels of nitro fatty acids (NO2-FA), such as nitroarachidonic, nitrolinoleic, nitrooleic, and dinitrooleic acids, are elevated under various inflammatory conditions, and this results in different anti-inflammatory effects. However, other multiply nitrated and nitro-oxidized FAs have not been studied so far. Owing to the low concentrations in vivo, NO2-FA analytics usually relies on targeted gas chromatography-tandem mass spectrometry (MS/MS) or liquid chromatography-MS/MS, and thus require standard compounds for method development. To overcome this limitation and increase the number and diversity of analytes, we performed in-depth mass spectrometry (MS) profiling of nitration products formed in vitro by incubating fatty acids with NO2BF4, and ONOO(-). The modified fatty acids were used to develop a highly specific and sensitive multiple reaction monitoring LC-MS method for relative quantification of 42 different nitrated and oxidized species representing three different groups: singly nitrated, multiply nitrated, and nitro-oxidized fatty acids. The method was validated in in vitro nitration kinetic studies and in a cellular model of nitrosative stress. NO2-FA were quantified in lipid extracts from 3-morpholinosydnonimine-treated rat primary cardiomyocytes after 15, 30, and 70 min from stress onset. The relatively high levels of dinitrooleic, nitroarachidonic, hydroxynitrodocosapenataenoic, nitrodocosahexaenoic, hydroxynitrodocosahexaenoic, and dinitrodocosahexaenoic acids confirm the presence of multiply nitrated and nitro-oxidized fatty acids in biological systems for the first time. Thus, in vitro nitration was successfully used to establish a targeted LC-MS/MS method that was applied to complex biological samples for quantifying diverse NO2-FA. Graphical Abstract Schematic representation of study design which combined in vitro nitration of different fatty acids, MS/MS characterization and optimization of MRM method for relative quantification, which was applied to follow dynamic of fatty acid nitration in cellular model of SIN-1 treated cardiomyoctes.

Abstract
Kisspeptin, encoded by the Kiss1 gene, has attracted attention as a key candidate neuropeptide in controlling puberty and reproduction via regulation of gonadotrophin-releasing hormone (GnRH) secretion in mammals. Pioneer studies with Kiss1 or its cognate receptor Gpr54 knockout (KO) mice showed the indispensable role of kisspeptin-GPR54 signalling in the control of animal reproduction, although detailed analyses of gonadotrophin secretion, especially pulsatile and surge-mode of luteinising hormone (LH) secretion, were limited. Thus, in the present study, we have generated Kiss1 KO rats aiming to evaluate a key role of kisspeptin in governing reproduction via pulse and surge modes of GnRH/LH secretion. Kiss1 KO male and female rats showed a complete suppression of pulsatile LH secretion, which is responsible for folliculogenesis and spermatogenesis, and an absence of puberty and atrophic gonads. Kiss1 KO female rats showed no spontaneous LH/follicle-stimulating hormone surge and an oestrogen-induced LH surge, suggesting that the GnRH surge generation system, which is responsible for ovulation, does not function without kisspeptin. Furthermore, challenge of major stimulatory neurotransmitters, such as monosodium glutamate, NMDA and norepinephrine, failed to stimulate LH secretion in Kiss1 KO rats, albeit they stimulated LH release in wild-type controls. Taken together, the results of the present study confirm that kisspeptin plays an indispensable role in generating two modes (pulse and surge) of GnRH/gonadotrophin secretion to regulate puberty onset and normal reproductive performance. In addition, the present study suggests that kisspeptin neurones play a critical role as a hub integrating major stimulatory neural inputs to GnRH neurones, using newly established Kiss1 KO rats, which serve as a useful model for detailed analysis of hormonal profiles.

Abstract
Hydrogen sulfide (H2S) has multiple physiological roles, for example, in vasodilation and inflammation. It is a highly reactive gas under ambient conditions, so controllable H2S donors are required for studying its biological functions. Here, we describe the design, synthesis and application of a H2S donor (SPD-2) that utilizes xanthone photochemistry to control H2S release. H2S generation from SPD-2 was completely dependent on UVA-irradiation (325-385nm), as confirmed by methylene blue assay and by the use of a H2S-selective fluorescent probe. SPD-2 was confirmed to provide controlled H2S delivery in live cells, and should be suitable for various biological applications.

Abstract
A series of 114 SIRT inhibitor candidates was assembled using 'click chemistry', by reacting two alkynes bearing 2-anilinobenzamide pharmacophore with 57 azide building blocks in the presence of Cu(I) catalyst. Screening identified two SIRT2-selective inhibitors, which were more SIRT2-selective than AGK2, a known SIRT2 inhibitor. These findings will be useful for further development of SIRT2-selective inhibitors.

Abstract
Two-photon-excitation release of nitric oxide (NO) from our recently synthesized photolabile NO donor, Flu-DNB, was confirmed to allow fine spatial and temporal control of NO release at the subcellular level in vitro. We then evaluated in vivo applications. Femtosecond near-infrared pulse laser irradiation of predefined regions of interest in living mouse brain treated with Flu-DNB induced NO-release-dependent, transient vasodilation specifically at the irradiated site. Photoirradiation in the absence of Flu-DNB had no effect. Further, NO release from Flu-DNB by pulse laser irradiation was shown to cause chemoattraction of microglial processes to the irradiated area in living mouse brain. To our knowledge, this is the first demonstration of induction of biological responses in vitro and in vivo by means of precisely controlled, two-photon-mediated release of NO.

Abstract
Nitroxyl (HNO) is a one-electron reduced and protonated derivative of nitric oxide (NO) and has characteristic biological and pharmacological effects distinct from those of NO. However, studies of its biosynthesis and activities are restricted by the lack of versatile HNO detection methods applicable to living cells. Here, we report the first metal-free and reductant-resistant HNO imaging probe available for use in living cells, P-Rhod. It consists of a rhodol derivative moiety as the fluorophore, linked via an ester moiety to a diphenylphosphinobenzoyl group, which forms an aza-ylide upon reaction with HNO. Intramolecular attack of the aza-ylide on the ester carbonyl group releases a fluorescent rhodol derivative. P-Rhod showed high selectivity for HNO in the presence of various biologically relevant reductants, such as glutathione and ascorbate, in comparison with previous HNO probes. We show that P-Rhod can detect not only HNO enzymatically generated in the horseradish peroxidase-hydroxylamine system in vitro but also intracellular HNO release from Angeli's salt in living cells. These results suggest that P-Rhod is suitable for detection of HNO in living cells.
