[PMID: 39094982 DOI: 10.1016/j.slast.2024.100174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 07/29/2024] [Accepted: 07/30/2024] [Indexed: 08/04/2024]
Abstract
An optimized Affinity Selection-Mass Spectrometry (AS-MS) workflow has been developed for the efficient identification of potent USP1 inhibitors. USP1 was immobilized on agarose beads, ensuring low small molecule retention, efficient protein capture, and protein stability. The binding affinity of 49 compounds to USP1 was evaluated using the optimized AS-MS method, calculating binding index (BI) values for each compound. Biochemical inhibition assays validated the AS-MS results, revealing a potential correlation between higher BI values and lower IC50 values. This optimized workflow enables rapid identification of high-quality USP1 inhibitor hits, facilitating structure-activity relationship studies and accelerating the discovery of potential cancer therapeutics.

Abstract
In our study, a method based on affinity ultrafiltration screening coupled with UPLC-ESI-Orbitrap-MS technology was established to select Glucagon-like peptide-1 receptor (GLP-1R) agonists from natural products, and as an example, the GLP-1R agonists from Panax ginseng was selected using our established method. As a result, total five GLP-1R agonists were selected from Panax ginseng for the first time. Our results indicated that activating GLP-1R to promote insulin secretion probably was another important hypoglycemia mechanism for ginsenosides in Panax ginseng, which had great influence on the study of the anti-diabetes effect of ginsenosides.

Abstract
Meconopsis integrifolia (Maxim.) Franch. is used extensively in traditional Tibetan medicine for its potent anti-inflammatory properties. In this study, six cyclooxygenase-2 (COX-2) inhibitors were purified from M. integrifolia using high-speed counter-current chromatography guided by ultrafiltration liquid chromatography (ultrafiltration-LC). First, ultrafiltration-LC was performed to profile the COX-2 inhibitors in M. integrifolia. The reflux extraction conditions were further optimized using response surface methodology, and the results showed that the targeted COX-2 inhibitors could be well enriched under the optimized extraction conditions. Then the six target COX-2 inhibitors were separated by high-speed countercurrent chromatography with a solvent system composed of ethyl acetate/n-butanol/water (4:1:4, v/v/v. Finally, the six COX-2 inhibitors, including 21.2 mg of 8-hydroxyluteolin 7-sophoroside, 29.6 mg of 8-hydroxyluteolin 7-[6'''-acetylallosyl-(1→2)-glucoside], 42.5 mg of Sinocrassoside D3, 54.1 mg of Hypolaetin 7-[6'''-acetylallosyll-(l→2)-3''-acetylglucoside, 30.6 mg of Hypolaetin 7-[6'''-acetylallosyll-(l→2)-6''-acetylglucoside and 17.8 mg of Hypolaetin were obtained from 500 mg of sample. Their structures were elucidated by 1 H-NMR spectroscopy. This study reveals that ultrafiltration-LC combined with high-speed counter-current chromatography is a robust and efficient strategy for target-guided isolation and purification of bioactive molecules. It also enhances the scientific understanding of the anti-inflammatory properties of M. integrifolia but also paves the way for its further medicinal applications.

Abstract
In the present study, a comprehensive strategy integrating affinity ultrafiltration high-performance liquid chromatography quadrupole-time-of-flight mass spectrometry (UF-HPLC-Q-TOF-MS), in silico molecular docking and bioassays was established to rapidly screen natural SOD activators from traditional Chinese medicines. As illustrative case studies, Schisandra chinensis, Fructus cnidii and Radix ophiopogonis were chosen to develop and verify the strategy. The HPLC-Q-TOF-MS was used to identify the compounds in comparison with reference standards and literature data. A total of eight compounds, including four biphenyl-cyclooctene ligands from Schisandra chinensis and four coumarins from Fructus cnidii, were found to potentially increase SOD activities. No ligands were found in the extract of Radix ophiopogonis. Then, in silico molecular docking was performed to investigate the binding site and binding affinity of the candidates on SOD. Compared to the nonspecific ligands screened from the extract, the specific ligands presented stronger binding affinities. In addition, the activity and kinetic parameters of the SOD-ligand were investigated through an improved pyrogallol autoxidation method. Gomisin J and xanthotoxin showed a stronger ability to increase SOD activities. The present study indicated that combining UF-HPLC-Q-TOF-MS and in silico molecular docking offers a powerful and meaningful tool to rapidly screen SOD activators from traditional Chinese medicines.

Abstract
The purpose of the study was to establish a rapid analytical strategy to screen potential anti-inflammatory compounds from Flos Chrysanthemum flower. The enzyme assay was conducted to prescreen botanical extracts, in which Chrysanthemum morifolium aqueous extract (CME) displayed hyaluronidase (HAase) inhibitory activity in a dose-dependent manner with the values of 8.31, 24.25, and 66.51% at concentrations of 1.00, 2.00, and 4 0.00 mg/mL, respectively. Eight potential compounds targeting HAase (compounds 9, 10, 11, 13, 15, 17, 20 and 21) from CME were screened using ultrafiltration affinity liquid chromatography coupled with mass spectrometry (UF-LC-MS) technology. The well-known inhibitor, dipotassium glycyrrhizinate (DG), was used as a positive control and competitive ligand to eliminate false positives. Then, four of these potential components (compounds 9, 10, 17, and 21), namely eriodictyol-7-O-glucoside, luteoloside, apigenin-7-O-glucoside and diosmetin-7-O-glucoside, were distinguished as potent HAase specific inhibitor candidates with high BD and CBD values. The enzyme inhibitory activities of candidate compounds were verified using enzyme inhibition assay. At a concentration of 1000 μM, compounds 9, 10, 17, and 21 showed 40.15, 44.85, 18.04, and 24.15% inhibition of HAase, respectively. Furthermore, all the four compounds significantly decreased the production of nitric oxide (NO) and IL-6, and significantly suppressed the mRNA expression of inducible NO synthase (iNOS) and IL-1β in both murine and human macrophages.

Abstract
INTRODUCTION Screening and analysis of bioactive components from natural products is a fundamental part of new drug development and innovation. Two-dimensional (2D) chromatography has been demonstrated to be an effective method for screening and preparation of specific bioactive components from complex natural products. OBJECTIVE To collect details of application of 2D chromatography in screening of natural product bioactive components and to outline the research progress of different separation mechanisms and strategies. METHODOLOGY Three screening strategies based on 2D chromatography are reviewed, including traditional separation-based screening, bioactivity-guided screening and affinity chromatography-based screening. Meanwhile, in order to cover these aspects, selections of different separation mechanisms and modes are also presented. RESULTS Compared with traditional one-dimensional (1D) chromatography, 2D chromatography has unique advantages in terms of peak capacity and resolution, and it is more effective for screening and identifying bioactive components of complex natural products. CONCLUSION Screening of natural bioactive components using 2D chromatography helps separation and analysis of complex samples with greater targeting and relevance, which is very important for development of innovative drug leads.

Abstract
Phenotypic resistance to fluoroquinolones due to mutational changes in the gyrA and parC genes is common among clinical Vibrio strains; the plasmid-mediated quinolone resistance (PMQR) qnrVC genes were also suggested to play a role in enhancing resistance development. This study investigated the prevalence of qnrVC genes in foodborne Vibrio strains collected in Shenzhen, China, during the period August 2015 and April 2017. A total of 1811 foodborne Vibrio strains were collected, mostly (73.8%) from shrimp samples and 20.2% of these strains were resistant to ciprofloxacin. Investigation of resistance mechanisms showed that mutations in the gyrA and parC genes were commonly associated with ciprofloxacin resistance. The presence of qnrVC genes was shown to enhance ciprofloxacin MIC in Vibrio strains and 69.7% of Vibrio strains that harbored target mutations also carried qnrVC genes, yet only 27.5% of the isolates not harboring such mutations carried the qnrVC genes. A total of 141 strains were found to carry the qnrVC alleles, with qnrVC5 and qnrVC1 being the most common types. Fourteen qnrVC variant genes that contained novel mutations were detectable, with 12 (85.7%) involving qnrVC5-like alleles. For the first time, we found a variant that was likely formed by the recombination of qnrVC1 and qnrVC5. The genetic context of the qnrVC genes found in this study was highly variable, with most being accompanied by mobile genetic elements and other resistance genes. The increasing prevalence of qnrVC genes in Vibrio and its contribution on mediating the development of ciprofloxacin resistance need to be further investigated.

Abstract
A more accurate HPLC-MS screening method combining functional enzyme assay and affinity ultrafiltration screening assay was developed and applied for the screening of natural product inhibitors of α-glucosidase from Cercis chinensis Bunge fruits. The enzyme assay was conducted to prescreen botanical extracts, in which maltose was used as the substrate and detection object. That showed the Cercis chinensis Bunge fruits demonstrated higher α-glucosidase inhibitory activity (IC50 = 11.94 ± 1.23 μg/mL) than acarbose (IC50 = 44.03 ± 4.37 μg/mL) (n = 3, p < 0.05). Subsequently, twelve bioactive components targeting α-glucosidase were screened out and identified using affinity ultrafiltration coupled to liquid chromatography-mass spectrometry. The known inhibitor, acarbose, was used as a positive control and competitive ligand to eliminate false positives. Moreover, bindings of the twelve components to the active site of α-glucosidase were investigated via molecular docking, which further confirmed the results of the screening assay.

Abstract
The BCL-XL-selective inhibitors exhibit potential clinical application value when combined with chemotherapeutic drugs for the treatment of solid tumors. However, their efficacy in these settings is still low when treated with BCL-XL inhibitors alone in solid tumors. The mechanism responsible for the poor efficacy remains unclear. We show here that unable to interact with target of BCL-XL-selective inhibitors caused by invalid entry into mitochondria is essential for their inefficacy in solid tumors. We demonstrated in non-small-cell lung cancer (NSCLC) cells that the instability of A-1155463 in cells as well as invalid entry into mitochondria of A-1331852, two BCL-XL-selective inhibitors, accounted for their off-target problems. Furthermore, we found that a mitochondria-targeted, non-toxic small molecule NA-2a improved the on-target effect of A-1331852 to enhance its apoptotic regulatory activity, thereby increasing its anticancer activity in NSCLC. Our results indicated that NA-2a was selectively enriched in mitochondria transported by organic-anion-transporting polypeptide (OATP) transporters, which altered the permeability of the mitochondrial membrane, thereby promoting the entrance of A-1331852 to mitochondria and enhancing its disruption of the BIM-BCL-XL complex, which finally led to the increased anticancer activity in vitro and in vivo. Collectively, our data provided overwhelming evidence that the combination of NA-2a and A-1331852 could be used as a promising synergistic therapeutic agent in NSCLC therapy.

Abstract
Valeriana rigida Ruiz & Pav. (V. rigida) has long been used as a herbal medicine in Peru; however, its phytochemicals and pharmacology need to be scientifically explored. In this study, we combined the offline 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH)-/ultrafiltration-high-performance liquid chromatography (HPLC) and high-speed counter-current chromatography (HSCCC)/pH-zone-refining counter-current chromatography (pH-zone-refining CCC) to screen and separate the antioxidants and aldose reductase (AR) inhibitors from the 70% MeOH extract of V. rigida, which exhibited remarkable antioxidant and AR inhibitory activities. Seven compounds were initially screened as target compounds exhibiting dual antioxidant and AR inhibitory activities using DPPH-/ultrafiltration-HPLC, which guided the subsequent pH-zone-refining CCC and HSCCC separations of these target compounds, namely 3-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, 3,4-O-di-caffeoylquinic acid, 3,5-O-di-caffeoylquinic acid, 4,5-O-di-caffeoylquinic acid, and 3,4,5-O-tri-caffeoylquinic acid. These compounds are identified for the first time in V. rigida and exhibited remarkable antioxidant and AR inhibitory activities. The results demonstrate that the method established in this study can be used to efficiently screen and separate the antioxidants and AR inhibitors from natural products and, particularly, the root extract of V. rigida is a new source of caffeoylquinic acids with antioxidant and AR inhibitory activities, and it can be used as a potential functional food ingredient for diabetes.

Yuan YC, Bai XL, Liu YM, Tang XY, Yuan H, Liao X. Ligand fishing based on cell surface display of enzymes for inhibitor screening. Anal Chim Acta 2021; 1156:338359. [PMID: 33781459 DOI: 10.1016/j.aca.2021.338359] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 02/21/2021] [Accepted: 02/25/2021] [Indexed: 11/19/2022]
Abstract
Ligand fishing for screening of enzyme inhibitors from complex chemical systems using baits prepared by cell surface display of the enzyme is herein demonstrated for the first time. Tyrosine phosphatase 1B (PTP1B), used as a model enzyme in this work, is displayed on the surface of E. coli cells by using ice nucleation protein (INP) as the anchoring motif. Infusion of PTP1B is characterized by western blot, immunofluorescence, proteinase K accessibility, and enzyme activity assays. Surface displayed PTP1B exhibits a maximum of 5.62 ± 0.251 U/OD600 enzymatic activity and a better stability compared with free enzyme. PTP1B displayed cells are used as solid-phase extraction adsorbent in combination with HPLC-MS to screen the inhibitors from the extracts of Rhodiola rosea, a traditional Chinese medicinal plant. Among many well-known active ingredients only arbutin is fished out with an IC50 value of 20.5 ± 0.873 μM, showing the inhibitor screening is highly selective. Furthermore, the equilibrium dissociation constant (KD) of the complex of arbutin and PTP1B was determined to be 79.6 μM by localized surface plasma resonance (LSPR) assay. The proposed ligand fishing technique using recombinant cells as baits opens a new avenue for screening of active compounds from natural products with accuracy and specificity.

Exploring new targets and chemical space with affinity selection-mass spectrometry. Nat Rev Chem 2020; 5:62-71.

Abstract
Affinity selection-mass spectrometry (AS-MS) is a high-throughput screening (HTS) technique for drug discovery that enables rapid screening of large collections of compounds to identify ligands for a specific biomolecular target. AS-MS is a binding assay that is insensitive to the functional effects a ligand might have, which is important because it lets us identify novel ligands irrespective of their binding site. This approach is gaining popularity, notably due to its role in the emergence of useful agents for targeted protein degradation. This Perspective highlights the use of AS-MS techniques to explore broad chemical space and identify small-molecule ligands for biological targets that have proven challenging to address with other screening paradigms. We present chemical structures of reported AS-MS hits to illustrate the potential of this screening approach to deliver high-quality hits for further optimization. AS-MS has, thus, evolved from being an infrequent alternative to traditional HTS or DNA-encoded library strategies to now firmly establishing itself as a HTS approach for drug discovery.

Abstract
A method based on enzyme blocking combined with ultrafiltration liquid chromatography-mass spectrometry (LC-MS) has been developed to identify xanthine oxidase (XOD) inhibitors in the roots of Lindera reflexa Hemsl (LR) and determine their binding positions. Allopurinol and febuxostat, known XOD inhibitors, which occupy different binding positions in XOD, were used as blockers and pre-incubated with XOD. Then the LR extract was incubated without XOD, and with XOD, allopurinol-blocked XOD and febuxostat-blocked XOD before ultrafiltration LC-MS was performed. By comparing the chromatographic profiles of the incubation samples, not only the ligands, but also the binding position of these ligands with XOD could be determined. Finally, three compounds, pinosylvin, pinocembrin and methoxy-5-hydroxy-trans-stilbene, were identified as potential XOD inhibitors and the binding modes of these three compounds were shown to be similar to those of febuxostat. To verify the XOD inhibitory activity of the screened compounds, the microplate method and molecular docking in silico were used to evaluate the enzyme inhibitory activities and the binding positions with XOD. The results showed that the developed method could screen for XOD ligands in LR extracts and also determine the binding positions of the ligands. To our knowledge, this is the first report of the XOD inhibitory activity of these three compounds.

Abstract
The emergence and worldwide prevalence of New Delhi metallo-β-lactamase 1 (NDM-1) expressing Gram-negative bacteria with resistance against most β-lactam antibiotics pose a serious threat to human health. However, no NDM-1 inhibitors are clinically approved at present. Herein, based on the lead compound captopril, a series of compounds were designed, synthesized, and evaluated for NDM-1 inhibitory activities. All designed compounds showed single digit micromolar or submicromolar NDM-1 inhibitory activities, which were much more potent than that of captopril. Among them, compounds 14a and 14m exhibited excellent NDM-1 inhibitory activities, with IC50 values of 0.10 and 0.12 μM, respectively. Further studies demonstrated that compound 14m displayed low cytotoxicity, good water solubility, high metabolic stability, and low acute toxicity in mice. Importantly, compound 14m exhibited potent synergistic antimicrobial activities with Meropenem (MEM) for the treatment of clinically isolated NDM-1-expressing strains.

Abstract
The anti-inflammatory active ingredients of Zhi-Shi-Zhi-Zi-Chi-Tang (ZSZZCT), a traditional Chinese medicine formula, were predicted and identified using an approach based on activity index, LC-MS, semi-preparative LC and NMR. Firstly, the whole extract of ZSZZCT was analyzed using liquid chromatography-quadrupole time of flight-mass spectrometry (LC-Q-TOF-MS) and liquid chromatography - ion trap mass spectrometry (LC-IT-MS), 79 constituents were detected and 39 constituents were identified unambiguously or tentatively. Subsequently, the whole extract of the formula was separated into multiple components and the activity index method was used to calculate index values of the 79 constituents by integrating the chemical and pharmacological information of multiple components. Four polymethoxyl flavones were predicted as the major active constituents according to the activity index values. Furthermore, three polymethoxyl flavones were prepared using the strategy with semi-preparative LC guided by LC-MS, and their anti-inflammatory activities were validated. The results show that three polymethoxyl flavones with higher positive index values, i.e., 3, 5, 6, 7, 8, 3', 4'-heptamethoxyflavone, 3-hydroxynobiletein and tangeretin had significant anti-inflammatory effects. In conclusion, the predicted results indicated that the activity index method is feasible for the accurate prediction of active constituents in TCM formulae.

Abstract
The real-time tracking of localization and dynamics of small molecules in organelles helps to understand their function and identification of their potential targets at subcellular resolution. To identify the mitochondrion-targeting effects of small molecules (NA-17 and NA-2a) in cancer cells, we used mass spectrometry to study their distribution and accumulation in mitochondria and in the surrounding cytoplasm thus enabling tracing of action processes of therapeutic compounds. Colocalization analysis with the aid of imaging agents suggests that both NA-17 and NA-2a display mitochondrion-targeting effects. However, MS analysis reveals that only NA-2a displays both a mitochondrion-targeting effect and an accumulation effect, whereas NA-17 only distributes in the surrounding cytoplasm. A combination of mitochondrion imaging, immunoblotting, and MS analysis in mitochondria indicated that NA-17 neither has the ability to enter mitochondria directly nor displays any mitochondrion-targeting effect. Further studies revealed that NA-17 could not enter into mitochondria even when the mitochondrial permeability in cells changed after NA-17 treatment, as was evident from reactive oxygen species (ROS) generation and cytochrome c release. In the process of cellular metabolism, NA-17 itself is firmly restricted to the cytoplasm during the metabolic process, but its metabolites containing fluorophores could accumulate in mitochondria for cell imaging. Our studies have furnished new insights into the drug metabolism processes.

Abstract
The worldwide emergence of New Delhi metallo-β-lactamase-1 (NDM-1) as a carbapenemase able to hydrolyze nearly all available β-lactam antibiotics has characterized the past decade, endangering efficacious antibacterial treatments. No inhibitors for NDM-1 are available in therapy, nor are promising compounds in the pipeline for future NDM-1 inhibitors. We report the studies dedicated to the design and development of effective NDM-1 inhibitors. The discussion for each agent moves from the employed design strategy to the ability of the identified inhibitor to synergize β-lactam antibiotics. A structural analysis of NDM-1 mechanism of action based on selected X-ray complexes is also reported: the intrinsic flexibility of the binding site and the comparison between penicillin/cephalosporin and carbapenem mechanisms of hydrolysis are evaluated. Despite the valuable progress in terms of structural and mechanistic information, the design of a potent NDM-1 inhibitor to be introduced in therapy remains challenging. Certainly, only the deep knowledge of NDM-1 architecture and of the variable mechanism of action that NDM-1 employs against different classes of substrates could orient a successful drug discovery campaign.

Abstract
Misoprostol is a life-saving drug in many developing countries for women at risk of post-partum hemorrhaging owing to its affordability, stability, ease of administration and clinical efficacy. However, misoprostol lacks receptor and tissue selectivities, and thus its use is accompanied by a number of serious side effects. The development of pharmacological agents combining the advantages of misoprostol with improved selectivity is hindered by the absence of atomic details of misoprostol action in labor induction. Here, we present the 2.5 Å resolution crystal structure of misoprostol free-acid form bound to the myometrium labor-inducing prostaglandin E2 receptor 3 (EP3). The active state structure reveals a completely enclosed binding pocket containing a structured water molecule that coordinates misoprostol's ring structure. Modeling of selective agonists in the EP3 structure reveals rationales for selectivity. These findings will provide the basis for the next generation of uterotonic drugs that will be suitable for administration in low resource settings.

Abstract
Infections by carbapenem-resistant Enterobacteriaceae are difficult to manage owing to broad antibiotic resistance profiles and because of the inability of clinically used β-lactamase inhibitors to counter the activity of metallo-β-lactamases often harbored by these pathogens. Of particular importance is New Delhi metallo-β-lactamase (NDM), which requires a di-nuclear zinc ion cluster for catalytic activity. Here, we compare the structures and functions of clinical NDM variants 1-17. The impact of NDM variants on structure is probed by comparing melting temperature and refolding efficiency and also by spectroscopy (UV-visible, 1H NMR, and EPR) of di-cobalt metalloforms. The impact of NDM variants on function is probed by determining the minimum inhibitory concentrations of various antibiotics, pre-steady-state and steady-state kinetics, inhibitor binding, and zinc dependence of resistance and activity. We observed only minor differences among the fully loaded di-zinc enzymes, but most NDM variants had more distinguishable selective advantages in experiments that mimicked zinc scarcity imposed by typical host defenses. Most NDM variants exhibited improved thermostability (up to ∼10 °C increased Tm ) and improved zinc affinity (up to ∼10-fold decreased Kd, Zn2). We also provide first evidence that some NDM variants have evolved the ability to function as mono-zinc enzymes with high catalytic efficiency (NDM-15, ampicillin: kcat/Km = 5 × 106 m-1 s-1). These findings reveal the molecular mechanisms that NDM variants have evolved to overcome the combined selective pressures of β-lactam antibiotics and zinc deprivation.

Abstract
High-throughput identification of GPCR modulators through affinity MS screening.
G protein-coupled receptors (GPCRs) represent the largest class of cell surface proteins and thus constitute an important family of therapeutic targets. Therefore, significant effort has been put towards the identification of novel ligands that can modulate the activity of a GPCR target with high efficacy and selectivity. However, due to limitations inherent to the most common techniques for GPCR ligand discovery, there is a pressing need for more efficient and effective ligand screening methods especially for the identification of potential allosteric modulators. Here we present a high-throughput, label-free and unbiased screening approach for the identification of small molecule ligands towards GPCR targets based on affinity mass spectrometry. This new approach features the usage of target-expressing cell membranes rather than purified proteins for ligand screening and allows the detection of both orthosteric and allosteric ligands targeting specific GPCRs. Screening a small compound library with this approach led to the rapid discovery of an antagonist for the 5-HT receptor and four positive allosteric modulators for GLP-1 receptor that were not previously reported.

Abstract
Covering: 2000 to 2016Natural product extracts are a rich source of bioactive compounds. As a result, the screening of natural products for the identification of novel biologically active metabolites has been an essential part of several drug discovery programs. It is estimated that more than 70% of all drugs approved from 1981 and 2006, were either derived from or structurally similar to nature based compounds indicating the necessity for the development of a rapid method for the identification of novel compounds from plant extracts. The screening of biological matrices for the identification of novel modulators is nevertheless still challenging. In this review we discuss current techniques in phytochemical analysis and the identification of biologically active components.

Abstract
The immunoaffinity of protein with ligand is broadly involved in many bioanalytical methods. Affinity-ultrafiltration mass spectrometry (AUF-MS), a platform based on interaction of protein-ligand affinity, has been developed to fish out interesting molecules from complex matrixes. Here we reviewed the basics of AUF-MS and its recent applications to pharmaceutical field, i.e. target-oriented discovery of lead compounds from combinatorial libraries and natural product extracts, and determination of free drug concentration in biosamples. Selected practical examples were highlighted to illustrate the advances of AUF-MS in pharmaceutical fields. The future prospects were also presented.

Abstract
A simple, label-free, and visual photonic crystal-based β-lactamase biosensor was developed for β-lactam antibiotic and β-lactamase inhibitor in which the penicillinase (a β-lactamase) was immobilized on the pH-sensitive colloidal crystal hydrogel (CCH) film to form penicillinase colloidal crystal hydrogel (PCCH) biosensing film. The hydrolysis of penicillin G (a β-lactam antibiotic) can be catalyzed by penicillinase to produce penicilloic acid, leading to a pH decrease in the microenvironment of PCCH film, which causes the shrink of pH-sensitive CCH film and triggers a blue-shift of the diffraction wavelength. Upon the addition of β-lactamase inhibitor, the hydrolysis reaction is suppressed and no clear blue-shift is observed. The concentrations of β-lactam antibiotic and β-lactamase inhibitor can be sensitively evaluated by measuring the diffraction shifts. The minimum detectable concentrations for penicillin G and clavulanate potassium (a β-lactamase inhibitor) can reach 1 and 0.1 μM, respectively. Furthermore, the proposed method is highly reversible and selective, and it allows determination of penicillin G in fish pond water samples.

Abstract
The nucleoprotein (NP) of Ebola virus (EBOV) and Marburg virus (MARV) is an essential component of the viral ribonucleoprotein complex and significantly impacts replication and transcription of the viral RNA genome. Although NP is regarded as a promising antiviral druggable target, no chemical ligands have been reported to interact with EBOV NP or MARV NP. We identified two compounds from a traditional Chinese medicine Gancao (licorice root) that can bind both NPs by combining affinity mass spectrometry and metabolomics approaches. These two ligands, 18β-glycyrrhetinic acid and licochalcone A, were verified by defined compound mixture screens and further characterized with individual ligand binding assays. Accompanying biophysical analyses demonstrate that binding of 18β-glycyrrhetinic acid to EBOV NP significantly reduces protein thermal stability, induces formation of large NP oligomers, and disrupts the critical association of viral ssRNA with NP complexes whereas the compound showed no such activity on MARV NP. Our study has revealed the substantial potential of new analytical techniques in ligand discovery from natural herb resources. In addition, identification of a chemical ligand that influences the oligomeric state and RNA-binding function of EBOV NP sheds new light on antiviral drug development.

Abstract
Since its discovery in 2008, New Delhi metallo-β-lactamase-1 (NDM-1)-producing Enterobacteriaceae have disseminated globally, facilitated predominantly by gut colonization and the spread of plasmids carrying the bla NDM-1 gene. With few effective antibiotics against NDM-1 producers, and resistance developing to those which remain, there is an urgent need to develop new treatments. To date, most drug design in this area has been focused on developing an NDM-1 inhibitor and has been aided by the wealth of structural and mechanistic information available from high resolution x-ray crystallography and molecular modeling. This review aims to summarize current knowledge regarding the detection of NDM-1 producers, the mechanism of action of NDM-1 and to highlight recent attempts toward the development of clinically useful inhibitors.

Abstract
The growing number of bacterial pathogens that are resistant to numerous antibiotics is a cause for concern around the globe. There have been no new broad-spectrum antibiotics developed in the last 40 years, and the drugs we have currently are quickly becoming ineffective. In this article, we explore a range of therapeutic strategies that could be employed in conjunction with antibiotics and may help to prolong the life span of these life-saving drugs. Discussed topics include antiresistance drugs, which are administered to potentiate the effects of current antimicrobials in bacteria where they are no longer (or never were) effective; antivirulence drugs, which are directed against bacterial virulence factors; host-directed therapies, which modulate the host's immune system to facilitate infection clearance; and alternative treatments, which include such therapies as oral rehydration for diarrhea, phage therapy, and probiotics. All of these avenues show promise for the treatment of bacterial infections and should be further investigated to explore their full potential in the face of a postantibiotic era.

Abstract
In this study, a strategy based on ultrafiltration-high performance liquid chromatography coupled with diode array detection (UF-HPLC-DAD) was proposed for screening tyrosinase specific inhibitors in Xanthii fructus. The false negatives were distinguished by optimizing the UF-HPLC-DAD parameters to reduce the background noise; the false positives were distinguished by introducing a blocked tyrosinase in the control group for comparison. To obtain the best blocker, the competitive experiments were performed using various known ligands. Using this strategy, three competitive inhibitors (protocatechuic acid; 3,5-di-O-caffeoylquinic acid; and 1,5-di-O-caffeoylquinic acid) and one mixed-type inhibitor (chlorogenic acid) were identified. These results were verified using tyrosinase inhibition assay, kinetic analysis, and structural simulation of the complex. Our experimental results suggest that the proposed strategy could be useful for high-throughput identification of tyrosinase specific inhibitors in natural products.

Multiple ligand detection and affinity measurement by ultrafiltration and mass spectrometry analysis applied to fragment mixture screening. Anal Chim Acta 2015; 886:98-106.

Abstract
Binding affinity of a small molecule drug candidate to a therapeutically relevant biomolecular target is regarded the first determinant of the candidate's efficacy. Although the ultrafiltration-LC/MS (UF-LC/MS) assay enables efficient ligand discovery for a specific target from a mixed pool of compounds, most previous analysis allowed for relative affinity ranking of different ligands. Moreover, the reliability of affinity measurement for multiple ligands with UF-LC/MS has hardly been strictly evaluated. In this study, we examined the accuracy of K(d) determination through UF-LC/MS by comparison with classical ITC measurement. A single-point K(d) calculation method was found to be suitable for affinity measurement of multiple ligands bound to the same target when binding competition is minimized. A second workflow based on analysis of the unbound fraction of compounds was then developed, which simplified sample preparation as well as warranted reliable ligand discovery. The new workflow implemented in a fragment mixture screen afforded rapid and sensitive detection of low-affinity ligands selectively bound to the RNA polymerase NS5B of hepatitis C virus. More importantly, ligand identification and affinity measurement for mixture-based fragment screens by UF-LC/MS were in good accordance with single ligand evaluation by conventional SPR analysis. This new approach is expected to become a valuable addition to the arsenal of high-throughput screening techniques for fragment-based drug discovery.

Abstract
In fragment-based lead discovery (FBLD), a cascade combining multiple orthogonal technologies is required for reliable detection and characterization of fragment binding to the target. Given the limitations of the mainstream screening techniques, we presented a ligand-observed mass spectrometry approach to expand the toolkits and increase the flexibility of building a FBLD pipeline especially for tough targets. In this study, this approach was integrated into a FBLD program targeting the HCV RNA polymerase NS5B. Our ligand-observed mass spectrometry analysis resulted in the discovery of 10 hits from a 384-member fragment library through two independent screens of complex cocktails and a follow-up validation assay. Moreover, this MS-based approach enabled quantitative measurement of weak binding affinities of fragments which was in general consistent with SPR analysis. Five out of the ten hits were then successfully translated to X-ray structures of fragment-bound complexes to lay a foundation for structure-based inhibitor design. With distinctive strengths in terms of high capacity and speed, minimal method development, easy sample preparation, low material consumption and quantitative capability, this MS-based assay is anticipated to be a valuable addition to the repertoire of current fragment screening techniques.
