Rapid discovery of a novel "green" and natural GST inhibitor for sensitizing hepatocellular carcinoma to Cisplatin by visual screening strategy. J Pharm Anal 2024; 14:100923. [PMID: 38799232 PMCID: PMC11127223 DOI: 10.1016/j.jpha.2023.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 11/24/2023] [Accepted: 12/16/2023] [Indexed: 05/29/2024] Open
Abstract
Over-expression of glutathione S-transferase (GST) can promote Cisplatin resistance in hepatocellular carcinoma (HCC) treatment. Hence, inhibiting GST is an attractive strategy to improve Cisplatin sensitivity in HCC therapy. Although several synthesized GST inhibitors have been developed, the side effects and narrow spectrum for anticancer seriously limit their clinical application. Considering the abundance of natural compounds with anticancer activity, this study developed a rapid fluorescence technique to screen "green" natural GST inhibitors with high specificity. The fluorescence assay demonstrated that schisanlactone B (hereafter abbreviated as C1) isolated from Xue tong significantly down-regulated GST levels in Cisplatin-resistant HCC cells in vitro and in vivo. Importantly, C1 can selectively kill HCC cells from normal liver cells, effectively improving the therapeutic effect of Cisplatin on HCC mice by down-regulating GST expression. Considering the high GST levels in HCC patients, this compound demonstrated the high potential for sensitizing HCC therapy in clinical practice by down-regulating GST levels.

Discovery of potent inhibitors targeting Glutathione S-transferase of Wuchereria bancrofti: a step toward the development of effective anti-filariasis drugs. Mol Divers 2024; 28:765-785. [PMID: 36797509 DOI: 10.1007/s11030-023-10617-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 01/30/2023] [Indexed: 02/18/2023]
Abstract
Lymphatic filariasis (LF) is one of the major health problems for the human kind in developing countries including India. LF is caused by three major nematodes namely Wuchereria bancrofti, Brugia malayi, and Brugia timori. The recent statistics of World Health Organization (WHO) showed that 51 million people were affected and 863 million people from 47 countries around worldwide remain threatened by LF. Among them, 90% of the filarial infection was caused by the nematode W. bancrofti. Approved drugs were available for the treatment of LF but many of them developed drug resistance and no longer effective in all stages of the infection. In the current research work, we explored the Glutathione S-transferase (GST) of W. bancrofti, the key enzyme responsible for detoxification that catalyzes the conjugation of reduced GSH (glutathione) to xenobiotic compounds. Initially, we analyzed the stability of the WbGST through 200 ns MD simulation and further structure-based virtual screening approach was applied by targeting the substrate binding site to identify the potential leads from small molecule collection. The in silico ADMET profiles for the top-ranked hits were predicted and the predicted non-toxic lead molecules showed the highest docking score in the range of - 12.72 kcal/mol to - 11.97 kcal/mol. The cross docking of the identified hits with human GST revealed the potential binding specificity of the hits toward WbGST. Through WbGST-lead complex simulation, the lead molecules were observed to be stable and also intactly bound within the binding site of WbGST. Based on the computational results, the five predicted non-toxic molecules were selected for the in vitro assay. The molecules showed significant percentage of inhibition against the filarial worm Setaria digitata which is the commonly used model organism to evaluate the filarial activity. In addition, the molecules also showed better IC50 than the standard drug ivermectin. The identified lead molecules will lay a significant insight for the development of new drugs with higher specificity and lesser toxicity to control and treat filarial infections.

Some Benzoxazole Derivatives. LETT DRUG DES DISCOV 2022. [DOI: 10.2174/1570180819666220408133643] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Background:
The need to develop novel antimicrobial agents is apparent as infectious diseases
are increasing and resistance is rapidly developing against the drugs used in the treatment.
Objective:
This study aimed at the synthesis, antimicrobial susceptibility testing, and computational elucidation
of the mechanism of action of benzoxazole derivatives. It also aimed to compare the results obtained
in this study with the previous studies by our group. This would pave the way for designing novel
molecules with better antimicrobial activity. The other goal was pharmacophore analysis and in silico
ADMET analysis of them.
Methods:
In this study, synthesis, antimicrobial susceptibility testing, molecular docking, pharmacophore
analysis, and ADMET prediction were carried out.
Results:
The antimicrobial activity studies demonstrated that the synthesized compounds were active
against standard strains and clinical isolates at high concentrations. Then, the antimicrobial testing results
were compared to similar benzoxazoles tested by our group previously. Benzoxazole derivatives without
a methylene bridge between oxazole and phenyl ring were found to be more active than those with the
methylene bridge. This was also confirmed by molecular modeling undertaken in this study. The computational
results indicated that the antibacterial activity could be achieved by DNA gyrase inhibition.
Pharmacophore analysis showed that hydrogen bond acceptor (HBA), hydrogen bond donor (HBD), and
hydrophobicity features would contribute to the inhibition. In addition, in silico ADMET property investigation
of the compounds exhibited that they had the desired pharmacokinetics.
Conclusion:
Although antibacterial activity by inhibiting DNA gyrase is selective, the synthesized compounds
were active at much higher concentrations than the standards. Therefore, in prospective antimicrobial
studies, it is better to focus on benzoxazole derivatives without the methylene bridge. Since the
compounds had suitable in silico ADMET properties, screening them against the other pharmacologic
activities should be carried out. It is recommended to support the molecular modeling results with in vitro
or in vivo studies.

Abstract
BACKGROUND Glutathione transferases (GSTs) are a family of Phase II detoxification enzymes that have been shown to be involved in the development of multi-drug resistance (MDR) mechanism toward chemotherapeutic agents. GST inhibitors have, therefore, emerged as promising chemosensitizers to manage and reverse MDR. Colchicine (COL) is a classical antimitotic, tubulin-binding agent (TBA) which is being explored as anticancer drug. METHODS In the present work, the interaction of COL and its derivative 2,3-didemethylcolchicine (2,3-DDCOL) with human glutathione transferases (hGSTA1-1, hGSTP1-1, hGSTM1-1) was investigated by inhibition analysis, molecular modelling and molecular dynamics simulations. RESULTS The results showed that both compounds bind reversibly to human GSTs and behave as potent inhibitors. hGSTA1-1 was the most sensitive enzyme to inhibition by COL with IC50 22 μΜ. Molecular modelling predicted that COL overlaps with both the hydrophobic (H-site) and glutathione binding site (G-site) and polar interactions appear to be the driving force for its positioning and recognition at the binding site. The interaction of COL with other members of GST family (hGSTA2-2, hGSTM3-3, hGSTM3-2) was also investigated with similar results. CONCLUSION The results of the present study might be useful in future drug design and development efforts towards human GSTs.

Abstract
Glutathione transferase (GST P1-1) is a potential target for anticancer drugs. In this work, a series of 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX) derivatives as GST P1-1 inhibitors were designed, synthesized, and evaluated for their biological activity. Among the target compounds, 4n showed more selective inhibition toward GST P1-1 and GST M2-2, better water solubility, and more potent anticancer activities toward all the tested cancer cells (except for HOS) than its parent molecule. Detailed biological studies on the effect of 4n toward 143b cells revealed that 4n could arrest the cell cycle at the G2 phase and induced cell apoptosis in a dose-dependent manner. Like NBDHEX, 4n displayed good pharmacokinetic characteristics. An in vivo study on 143b xenograft models demonstrated that 4n could significantly reduce tumor growth in a dose-dependent manner, showing stronger antitumor activity than NBDHEX. Thus, 4n deserves to be further investigated as a potential antitumor agent for cancer therapy.

Background
According to the report published recently by the World Health Organization, the number of cancer cases in the world will increase to 22 million by 2030. So the anticancer drug research and development is taking place in the direction where the new entities are developed which are low in toxicity and are with improved activity. Benzoxazole and its derivative represent a very important class of heterocyclic compounds, which have a diverse therapeutic area. Recently, many active compounds synthesized are very effective; natural products isolated with benzoxazole moiety have also shown to be potent towards cancer.
Main text
In the last few years, many research groups have designed and developed many novel compounds with benzoxazole as their backbone and checked their anticancer activity. In the review article, the recent developments (mostly after 2015) made in the direction of design and synthesis of new scaffolds with very potent anticancer activity are briefly described. The effect of various heterocycles attached to the benzoxazole and their effect on the anticancer activity are thoroughly studied and recorded in the review.
Conclusion
These compiled data in the article will surely update the scientific community with the recent development in this area and will provide direction for further research in this area.

Abstract
Background:
The tyrosine kinase inhibitor, imatinib, used as a first line treatment in Chronic Myeloid
Leukemia (CML) patients, may lead to resistance and failure to therapy. Novel combinations of imatinib
with other drugs is a strategy to improve treatment efficiency.
Objective:
In this study, the antileukemic and apoptotic effects of a benzamide derivative XT5 and benzoxazole
derivative XT2B and their combination with imatinib were investigated in imatinib-sensitive (K562S) and
imatinib-resistant (K562R) CML cells.
Methods:
In vitro cytotoxicity was determined by MTT assay. Then, apoptotic effect of XT5 on CML cell lines
was tested by Annexin V flow cytometry, caspase activation and RT-PCR. Docking calculation was performed
using AutoDock Vina in PyMOL environment using AutoDock/Vina plugin for PyMOL.
Results:
According to our MTT assay data, XT5 indicated significant antiproliferative effect on cell lines, therefore
we investigated apoptotic effects of XT5. Treatment of K562 cell lines with a combination of XT5 and
imatinib-XT5 increased cytotoxicity, the Annexin V binding and caspase 3/7 activation. In addition to apoptosis
assays, we observed an increase in the expression levels of the pro-apoptotic (BAX, BAD and BIM) genes in
XT5 treated K562R and K562S cells. Molecular modelling experiments showed that XT5 showed hydrogenbonding
interactions with important amino acids of BCR-ABL kinase receptor; however XT2B did not show
any hydrogen bond interaction.
Conclusion:
Our results indicate that XT5 could be a potential candidate to be used as a new anticancer drug
and XT5 combination with imatinib as an alternate treatment strategy for overcoming imatinib resistance.

Abstract
Glutathione transferases (GST, EC. 2.5.1.18) are overexpressed in cancer cell and have been shown to be involved in cancer cell growth, differentiation and the development of multi-drug resistance (MDR) mechanism. Therefore, GST inhibitors are emerging as promising chemosensitizers to manage and reverse MDR. The present work aims to the synthesis, characterization and assessment of a new active-site chimeric inhibitor towards the MDR-involved human GSTP1-1 isoenzyme (hGSTP1-1). The inhibitor [BDA-Fe(III)] was designed to possess two functional groups: the anthraquinone moiety, as recognition element by hGSTP1-1 and a metal chelated complex [iminodiacetic acid-Fe(III)] as a reactive moiety, able to generate reactive oxygen species (ROS), through Fenton reaction. Upon binding of the BDA-Fe(III) to hGSTP1-1 in the presence of hydrogen peroxide, reactive oxygen species (ROS) are generated, which promoted the specific cleavage of hGSTP1-1 in a time and concentration-dependent manner. Electrophoretic analysis showed that each enzyme subunit is cleaved at a single site. Amino acid sequencing as well as molecular modelling studies established that the cleaved peptide bond is located between the amino acids Tyr103 and Ile104. This ligand-induced hGSTP1-1 degradation and inactivation strategy is discussed as a new approach towards chemosensitization of MDR cancer cells.

Abstract
Human GSTP1-1 is one of the most important proteins, which overexpresses in a large number of human tumours and is involved in the development of resistance to several anticancer drugs. So, it has become an important target in cancer treatment. In this study, 12 benzothiazole derivatives were synthesized and screened for their in vitro inhibitory activity for hGSTP1-1. Among these compounds, two of them (compounds #2 and #5) have been found to be the leads when compared with the reference drug etoposide. In order to analyse the structure-activity relationships (SARs) and to investigate the binding side interactions of the observed lead compounds, a HipHop pharmacophore model was generated and the molecular docking studies were performed by using CDocker method. In conclusion, it is observed that the lead compounds #2 and #5 possessed inhibitory activity on the hGSTP1-1 by binding to the H-site as a substrate in which the para position of the phenyl ring of the benzamide moiety on the benzothiazole ring is important. Substitution at this position with a hydrophobic group that reduces the electron density at the phenyl ring is required for the interaction with the H side active residue Tyr108.

Abstract
Angiotensin-converting enzyme (ACE), a membrane-bound zinc metallopeptidase, catalyzes the formation of Angiotensin-II (AngII) and the deactivation of bradykinin in the renin-angiotensin-aldosterone and kallikrein-kinin systems. As a hydrolysis product of ACE, AngII is regarded as an inhibitor and displays stronger competitive inhibition in the C-domain than the N-domain of ACE. However, the AngII binding differences between the two domains and the mechanisms behind AngII dissociation from the C-domain are rarely explored. In this work, molecular docking, Molecular Mechanics/Poisson-Boltzmann Surface Area calculation, and steered molecular dynamics (SMD) are applied to explore the structures and interactions in the binding or unbinding of AngII with the two domains of human somatic ACE. Calculated free energy values suggest that the C-domain-AngII complex is more stable than the N-domain-AngII complex, consistent with available experimental data. SMD simulation results imply that electrostatic interaction is dominant in the dissociation of AngII from the C-domain. Moreover, Gln106, Asp121, Glu123, and Tyr213 may be the key residues in the unbinding pathway of AngII. The simulation results in our work provide insights into the interactions between the two domains of ACE and its natural peptide inhibitor AngII at a molecular level. Moreover, the results provide theoretical clues for the design of new inhibitors.

Abstract
The 6-((7-nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)hexan-1-ol (NBDHEX, 1), a "suicide inhibitor" of the glutathione-S-transferase GSTP1-1, showed pro-apoptotic properties in tumor cells, but in vivo studies were limited by poor bioavailability and high affinity towards GSTM2-2, expressed in many non-cancerous tissues. Here we describe the synthesis and biological characterization of new 1 analogs (2-40), in which the hydroxyhexyl portion at the C4-sulfur atom has been replaced with phenyl-containing moieties as well as substituted alkyl chains. Some of the new compounds displayed 10-100 times increased water-solubility (8, 11, 17, 26-28, 34, 35), and most of them showed higher GSTP1-1 selectivity (2-20, 23-26, 31-33, 35) than 1. The presence of a phenyl ring with polar substituents is in general associated, with some exceptions (23, 24) to low cytotoxicity in osteosarcoma U-2OS cells. Differently, some alkyl derivatives possess cytotoxicity comparable (26, 34, 35) or higher (30, 32) than 1. Among the novel compounds, selected ones (26, 27, 34, and 35) deserve further investigation for their anticancer potential.

Molecular modeling and MM-PBSA free energy analysis of endo-1,4-β-xylanase from Ruminococcus albus 8. Int J Mol Sci 2014; 15:17284-303.

Abstract
Endo-1,4-β-xylanase (EC 3.2.1.8) is the enzyme from Ruminococcus albus 8 (R. albus 8) (Xyn10A), and catalyzes the degradation of arabinoxylan, which is a major cell wall non-starch polysaccharide of cereals. The crystallographic structure of Xyn10A is still unknown. For this reason, we report a computer-assisted homology study conducted to build its three-dimensional structure based on the known sequence of amino acids of this enzyme. In this study, the best similarity was found with the Clostridium thermocellum (C. thermocellum) N-terminal endo-1,4-β-D-xylanase 10 b. Following the 100 ns molecular dynamics (MD) simulation, a reliable model was obtained for further studies. Molecular Mechanics/Poisson-Boltzmann Surface Area (MM-PBSA) methods were used for the substrate xylotetraose having the reactive sugar, which was bound in the -1 subsite of Xyn10A in the 4C1 (chair) and 2SO (skew boat) ground state conformations. According to the simulations and free energy analysis, Xyn10A binds the substrate with the -1 sugar in the 2SO conformation 39.27 kcal·mol(-1) tighter than the substrate with the sugar in the 4C1 conformation. According to the Xyn10A-2SO Xylotetraose (X4(sb) interaction energies, the most important subsite for the substrate binding is subsite -1. The results of this study indicate that the substrate is bound in a skew boat conformation with Xyn10A and the -1 sugar subsite proceeds from the 4C1 conformation through 2SO to the transition state. MM-PBSA free energy analysis indicates that Asn187 and Trp344 in subsite -1 may an important residue for substrate binding. Our findings provide fundamental knowledge that may contribute to further enhancement of enzyme performance through molecular engineering.
