Int J Mol Sci 2022; 23:ijms231810259. [PMID: 36142164 PMCID: PMC9499002 DOI: 10.3390/ijms231810259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 08/31/2022] [Accepted: 09/03/2022] [Indexed: 11/18/2022] Open
Abstract
A series of N-arylsulfonyl-indole-2-carboxamide derivatives have been identified as potent fructose-1,6-bisphosphatase (FBPase) inhibitors (FBPIs) with excellent selectivity for the potential therapy of type II diabetes mellitus. To explore the structure–activity relationships (SARs) and the mechanisms of action of these FBPIs, a systematic computational study was performed in the present study, including three-dimensional quantitative structure–activity relationship (3D-QSAR) modeling, pharmacophore modeling, molecular dynamics (MD), and virtual screening. The constructed 3D-QSAR models exhibited good predictive ability with reasonable parameters using comparative molecular field analysis (q2 = 0.709, R2 = 0.979, rpre2 = 0.932) and comparative molecular similarity indices analysis (q2 = 0.716, R2 = 0.978, rpre2 = 0.890). Twelve hit compounds were obtained by virtual screening using the best pharmacophore model in combination with molecular dockings. Three compounds with relatively higher docking scores and better ADME properties were then selected for further studies by docking and MD analyses. The docking results revealed that the amino acid residues Met18, Gly21, Gly26, Leu30, and Thr31 at the binding site were of great importance for the effective bindings of these FBPIs. The MD results indicated that the screened compounds VS01 and VS02 could bind with FBPase stably as its cognate ligand in dynamic conditions. This work identified several potential FBPIs by modeling studies and might provide important insights into developing novel FBPIs.

Abstract
With a resurgence of covalent drugs, there is an urgent need for the identification of new moieties capable of cysteine bond formation. Herein, we report on the N-acylamino saccharin moieties capable of novel covalent reactions with cysteine. Their utility as alternative electrophilic warheads was demonstrated through the covalent modification of fructose-1,6-bisphosphatase (FBPase), a promising target associated with cancer and type 2 diabetes. The cocrystal structure of title compound W8 bound with FBPase unexpectedly revealed that the N-acylamino saccharin moiety worked as an electrophile warhead that covalently modified the noncatalytic C128 site in FBPase while releasing saccharin, suggesting a previously undiscovered covalent reaction mechanism of saccharin derivatives with cysteine. Treatment of title compound W8 displayed potent inhibition of glucose production in vitro and in vivo. This newly discovered reactive warhead supplements the current repertoire of cysteine covalent modifiers while avoiding some of the limitations generally associated with established moieties.

Abstract
We review 50 years of use of 2',3'-O-trinitrophenyl (TNP)-ATP, a fluorescently tagged ATP analog. It has been extensively used to detect binding interactions of ATP to proteins and to measure parameters of those interactions such as the dissociation constant, Kd, or inhibitor dissociation constant, Ki. TNP-ATP has also found use in other applications, for example, as a fluorescence marker in microscopy, as a FRET pair, or as an antagonist (e.g., of P2X receptors). However, its use in protein binding studies has limitations because the TNP moiety often enhances binding affinity, and the fluorescence changes that occur with binding can be masked or mimicked in unexpected ways. The goal of this review is to provide a clear perspective of the pros and cons of using TNP-ATP to allow for better experimental design and less ambiguous data in future experiments using TNP-ATP and other TNP nucleotides.

Abstract
Fructose-1,6-bisphosphatase (FBPase), as a key rate-limiting enzyme in the gluconeogenesis (GNG) pathway, represents a practical therapeutic strategy for type 2 diabetes (T2D). Our previous work first identified cysteine residue 128 (C128) was an important allosteric site in the structure of FBPase, while pharmacologically targeting C128 attenuated the catalytic ability of FBPase. Herein, ten approved cysteine covalent drugs were selected for exploring FBPase inhibitory activities, and the alcohol deterrent disulfiram displayed superior inhibitory efficacy among those drugs. Based on the structure of lead compound disulfiram, 58 disulfide-derived compounds were designed and synthesized for investigating FBPase inhibitory activities. Optimal compound 3a exhibited significant FBPase inhibition and glucose-lowering efficacy in vitro and in vivo. Furthermore, 3a covalently modified the C128 site, and then regulated the N125-S124-S123 allosteric pathway of FBPase in mechanism. In summary, 3a has the potential to be a novel FBPase inhibitor for T2D therapy.

Abstract
Liver fructose 1,6-bisphosphatase (FBPase) is a recognized regulatory enzyme of the gluconeogenesis pathway, which has emerged as a valid target to control gluconeogenesis-mediated overproduction of glucose. As such, the management of diabetes with FBPase inhibitors represents a potential alternative for the currently used antidiabetic agents. In this study, the FBPase inhibition of a panel of 55 structurally related flavonoids was tested, through a microanalysis screening system. Then, a subset of seven active inhibitors and their close chemical relatives were further evaluated by molecular dynamics (MD) simulations using a linear interaction energy (LIE) approach. The results obtained showed that D14 (herbacetin) was the most potent inhibitor, suggesting that the presence of -OH groups at the C-3, C-4', C-5, C-7, and C-8 positions, as well as the double bond between C-2 and C-3 and the 4-oxo function at the pyrone ring, are favorable for the intended effect. Furthermore, D14 (herbacetin) is stabilized by a strong interaction with the Glu30 side chain and the Thr24 backbone of FBPase. This is the first investigation studying the in vitro inhibitory effect of a panel of flavonoids against human liver FBPase, thus representing a potentially important step for the search and design of novel inhibitors of this enzyme.

Abstract
Fructose 1,6-bisphosphatase (FBPase) has attracted substantial interest as a target associated with cancer and type 2 diabetes. Herein, we found that disulfiram and its derivatives can potently inhibit FBPase by covalently binding to a new C128 allosteric site distinct from the original C128 site in APO FBPase. Further identification of the allosteric inhibition mechanism reveals that the covalent binding of a fragment of 214 will result in the movement of C128 and the dissociation of helix H4 (123-128), which in turn allows S123 to more easily form new hydrogen bonds with K71 and D74 in helix H3 (69-72), thereby inhibiting FBPase activity. Notably, both disulfiram and 212 might moderately reduce blood glucose output in vivo. Therefore, our current findings not only identify a new covalent allosteric site of FBPase but also establish a structural foundation and provide a promising way for the design of covalent allosteric drugs for glucose reduction.

Abstract
Enzymes are a class of macromolecules that function as highly efficient and specific
biological catalysts requiring only mild reaction conditions. Enzymes are essential to
maintaining life activities, including promoting metabolism and homeostasis, and participating
in a variety of physiological functions. Accordingly, enzymatic levels and activity are
closely related to the health of the organism, where enzymatic dysfunctions often lead to corresponding
diseases in the host. Due to this, diagnosis of certain diseases is based on the levels
and activity of certain enzymes. Therefore, rapid real-time and accurate detection of enzymes
in situ are important for diagnosis, monitoring, clinical treatment and pathological
studies of disease. Fluorescent probes have unique advantages in terms of detecting enzymes,
including being simple to use in highly sensitive and selective real-time rapid in-situ noninvasive
and highly spatial resolution visual imaging. However, fluorescent probes are most
commonly used to detect oxidoreductases, transferases and hydrolases due to the processes
and types of enzyme reactions. This paper summarizes the application of fluorescent probes to
detect these three types of enzymes over the past five years. In addition, we introduce the
mechanisms underlying detection of these enzymes by their corresponding probes.

Abstract
Fructose-1, 6-bisphosphatase (FBPase) has been regarded as an attractive drug target to control blood glucose against Type 2 diabetes (T2D). In this study, by using the strategy of pharmacophore-based virtual screening, a novel scaffold inhibitor targeted the AMP allosteric site of human liver FBPase were screened, their inhibitory activities were further tested. The experimental results showed that compound H27 exhibited high inhibitory activities with the IC50 value of 5.3 μM. Therefore, compound H27 was chosen as the probe molecule, it's possible binding conformation targeted into FBPase was identified by using DOX2.0 strategy. The importance of key residues (T27, T31, K112 and R140) in allosteric site of FBPase for the binding inhibitors were validated by mutation experiments. The agreement between theory and experiment suggest that the interactional information of FBPase and inhibitors (H27) were reliable. On basis of these rational interactional information, the compound H29 was further designed to exhibit more potential FBPase inhibition (IC50 = 2.5 μM).

Abstract
This study aimed to characterize the full-length complementary DNA (cDNA) of fructose-1,6-bisphosphatase 1b (FBP1b) from fish Megalobrama amblycephala, and investigate its transcriptional response to glucose administration after the adaptation to high-carbohydrate diets. The cDNA obtained covered 1435 bp with an open reading frame of 1014 bp. Sequence alignment and phylogenetic analysis revealed a high degree of conservation (76-96%) among most fish and other vertebrates, retaining one N-linked glycosylation site, one N-terminal acetylation site, 13 phosphorylation sites, one fructose-1,6-bisphosphatase (FBPase) active site, five metal-binding sites, four substrate-binding sites, and several AMP-binding sites. The highest messenger RNA (mRNA) level of FBP1b was observed in liver followed by intestine, whereas relatively low values were detected in heart, gill, and eye. Then, the mRNA levels of FBP1b and the FBPase activity were both determined in the liver of fish injected intraperitoneally with 1.67 g glucose per kilogram body weight after being fed two dietary carbohydrate levels (30 and 42%) for 11 weeks. After the glucose load, the mRNA levels of FBP1b in both treatments decreased significantly to the basal value at 8 h and showed a slight increase afterward. However, the enzymatic activity showed no statistical difference during the first 4 h, but increased remarkably with further increasing times. In addition, both the mRNA levels and activities decreased significantly with increasing dietary carbohydrate levels. The results indicated that the FBP1b of M. amblycephala shared a high similarity with that of the other vertebrates. Its mRNA expression in liver was downregulated remarkably by a glucose administration, as also held true after the long-term adaptation of a carbohydrate-rich diet.
