Abstract
In this study, a novel approach exploiting the interactions between hydrogen sulfide (H2S) and ruthenium-nitrogen-carbon (Ru-N-C) nanozymes is presented, advancing H2S and cystathionine γ-lyase (CSE) biosensing techniques. Utilizing the intrinsic peroxidase-like activity of Ru-N-C nanozymes and the noticeable inhibition effect caused by H2S, an efficient, simple, and economical assay has been developed. This innovative method allows for the versatile real-time monitoring of H2S from various sources, including specialized donors and native bacterial production. Furthermore, the assay has been applied to reveal the interactions within tumor cells and tissues ex vivo, providing a clearer and simpler view of CSE expression levels through an improved colorimetric method. This contribution enhances our understanding of the complex roles of H2S metabolism and represents a significant advancement in the versatile application of nanozymes in biomedical research.

Le Corre L, Padovani D. Mechanism-based and computational modeling of hydrogen sulfide biogenesis inhibition: interfacial inhibition. Sci Rep 2023; 13:7287.

Abstract
Hydrogen sulfide (H2S) is a gaseous signaling molecule that participates in various signaling functions in health and diseases. The tetrameric cystathionine γ-lyase (CSE) contributes to H2S biogenesis and several investigations provide evidence on the pharmacological modulation of CSE as a potential target for the treatment of a multitude of conditions. D-penicillamine (D-pen) has recently been reported to selectively impede CSE-catalyzed H2S production but the molecular bases for such inhibitory effect have not been investigated. In this study, we report that D-pen follows a mixed-inhibition mechanism to inhibit both cystathionine (CST) cleavage and H2S biogenesis by human CSE. To decipher the molecular mechanisms underlying such a mixed inhibition, we performed docking and molecular dynamics (MD) simulations. Interestingly, MD analysis of CST binding reveals a likely active site configuration prior to gem-diamine intermediate formation, particularly H-bond formation between the amino group of the substrate and the O3' of PLP. Similar analyses realized with both CST and D-pen identified three potent interfacial ligand-binding sites for D-pen and offered a rational for D-pen effect. Thus, inhibitor binding not only induces the creation of an entirely new interacting network at the vicinity of the interface between enzyme subunits, but it also exerts long range effects by propagating to the active site. Overall, our study paves the way for the design of new allosteric interfacial inhibitory compounds that will specifically modulate H2S biogenesis by cystathionine γ-lyase.

Abstract
Significance: Hydrogen sulfide (H2S) plays critical roles in redox biology, and its regulatory effects are tightly controlled by its cellular location and concentration. The imbalance of H2S is believed to contribute to some pathological processes. Recent Advances: Downregulation of H2S requires chemical tools such as inhibitors of H2S-producing enzymes and H2S scavengers. Recent efforts have discovered some promising inhibitors and scavengers. These advances pave the road toward better understanding of the functions of H2S. Critical Issues: Precise H2S downregulation is challenging. The potency and specificity of current inhibitors are still far from ideal. H2S-producing enzymes are involved in complex sulfur metabolic pathways and ubiquitously present in biological matrices. The inhibition of these enzymes can cause unwanted side effects. H2S scavengers allow targeted H2S clearance, but their options are still limited. In addition, the scavenging process often results in biologically active by-products. Future Directions: Further development of potent and specific inhibitors for H2S-producing enzymes is needed. Scavengers that can rapidly and selectively remove H2S while generating biocompatible by-products are needed. Potential therapeutic applications of scavengers and inhibitors are worth exploring.

Abstract
Hydrogen Sulfide (H2S), an endogenously produced gasotransmitter, is involved in various important physiological and disease conditions, including vasodilation, stimulation of cellular bioenergetics, anti-inflammation, and pro-angiogenesis. In cancer, aberrant up-regulation of H2S-producing enzymes is frequently observed in different cancer types. The recognition that tumor-derived H2S plays various roles during cancer development reveals opportunities to target H2S-mediated signaling pathways in cancer therapy. In this review, we will focus on the mechanism of H2S-mediated protein persulfidation and the detailed information about the dysregulation of H2S-producing enzymes and metabolism in different cancer types. We will also provide an update on mechanisms of H2S-mediated cancer progression and summarize current options to modulate H2S production for cancer therapy.

Abstract
Hydrogen sulfide (H2S), the third gas signal molecule, is associated with the modulation of various physiological and pathological processes. Recent studies have reevealed that endogenous H2S may promote proliferation, induce angiogenesis and inhibit apoptosis, thereby stimulating oncogenesis. Conversely, decreased endogenous H2S release suppresses growth of various tumors including breast cancer. This observation suggests an alternative tumor therapy strategy by inhibiting H2S-producing enzymes to reduce the release of endogenous H2S. Breast cancer is the most common type of cancer in women. Due to the lack of approved targeted therapy, its recurrence and metastasis still affect its clinical treatment. In recent years, significant progress has been made in the control of breast cancer by using inhibitors on H2S-producing enzymes. This review summarized the roles of endogenous H2S-producing enzymes in breast cancer and the effects of the enzyme inhibitors on anticancer and anti-metastasis, with the aim of providing new insights for the treatment of breast cancer.

Abstract
The carotid body (CB) is responsible for the peripheral chemoreflex by sensing blood gases and pH. The CB also appears to act as a peripheral sensor of metabolites and hormones, regulating the metabolism. CB malfunction induces aberrant chemosensory responses that culminate in the tonic overactivation of the sympathetic nervous system. The sympatho-excitation evoked by CB may contribute to the pathogenesis of metabolic syndrome, inducing systemic hypertension, insulin resistance and sleep-disordered breathing. Several molecular pathways are involved in the modulation of CB activity, and their pharmacological manipulation may lead to overall benefits for cardiometabolic diseases. In this review, we will discuss the role of the CB in the regulation of metabolism and in the pathogenesis of the metabolic dysfunction induced by CB overactivity. We will also explore the potential pharmacological targets in the CB for the treatment of metabolic syndrome.

Abstract
Hydrogen sulfide (H2S) has been reported to play an important role in biological systems. More recently, sulfane sulfur (sulfur with 0 or -1 charge) molecules have been also reported to be involved in various biological phenomena such as regulation of redox signaling and antioxidant functions. Fluorescent probes are one of the important chemical tools because it is easy to use and enable the real-time detection of the target molecules in living cells and tissues. We have successfully developed a highly selective H2S-detecting fluorescent probe, HSip-1. HSip-1 has been designed on the basis of the facts that the macrocyclic polyamine ligands form a stable complex with Cu2+, and Cu2+ also reacts with H2S and make a stable CuS complex. SSip-1 is a fluorescent probe for detecting sulfane sulfur and this fluorescent probe is designed on the basis of the unique feature of sulfane sulfur to bind reversibly to other sulfur atoms and the intramolecular spirocyclization reaction of xanthene dyes. SSip-1 is a highly selective fluorescent probe and can detect sulfane sulfur reversibly. Both HSip-1 and SSip-1 were able to be used for the live-cell fluorescence imaging. Further, we applied HSip-1 to the high-throughput screening (HTS) for the inhibitors of 3-mercaptopyruvate sulfurtransferase (3MST), one of the reactive sulfur species (RSS)-generating enzymes. We successfully found new 3MST inhibitors by screening of 174,118 compounds. We expect that these fluorescent probes and inhibitors would be useful to elucidate new functions of RSS and RSS-generating enzymes.

Abstract
We identify three submicromolar inhibitors with new chemical scaffolds for cystathionine γ-lyase (CSE) by a tandem-well-based high-throughput assay. NSC4056, the most potent inhibitor with an IC50 of 0.6 μM, which is also known as aurintricarboxylic acid, selectively binds to Arg and Tyr residues of CSE active site and preferably inhibits the CSE activity in cells rather than cystathionine β-synthase (CBS), the other H2S-generating enzyme. Moreover, NSC4056 effectively rescues hypotension in hemorrhagic shock rats.
