Abstract
Cholinesterases catalyze the breakdown of the neurotransmitter acetylcholine (ACh), a naturally occurring neurotransmitter, into choline and acetic acid, allowing the nervous system to function properly. In the human body, cholinesterases come in two types, including acetylcholinesterase (AChE; E.C.3.1.1.7) and butyrylcholinesterase (BChE; E.C.3.1.1.8). Both cholinergic enzyme inhibitors are essential in the biochemical processes of the human body, notably in the brain. On the other hand, GSTs are found all across nature and are the principal Phase II detoxifying enzymes in eukaryotes and prokaryotes. Specific isozymes are identified as therapeutic targets because they are overexpressed in various malignancies and may have a role in the genesis of other diseases such as neurological disorders, multiple sclerosis, asthma, and especially cancer cell. Piperazine chemicals have a role in many biological processes and have fascinating pharmacological properties. As a result, therapeutically effective piperazine research is becoming more prominent. Half maximal inhibition concentrations (IC50 ) of piperazine derivatives were found in ranging of 4.59-6.48 µM for AChE, 4.85-8.35 µM for BChE, and 3.94-8.66 µM for GST. Also, piperazine derivatives exhibited Ki values of 8.04 ± 5.73-61.94 ± 54.56, 0.24 ± 0.03-32.14 ± 16.20, and 7.73 ± 1.13-22.97 ± 9.10 µM toward AChE, BChE, and GST, respectively. Consequently, the inhibitory properties of the AChE/BChE and GST enzymes have been compared to Tacrine (for AChE and BChE) and Etacrynic acid (for GST).

Abstract
Chalcone derivative, ethyl 2-(4-(3-(benzo[b]thiophen-2yl)acryloyl)phenoxy)acetate (I), was synthesized. Compound I was characterized by proton and carbon-13 nuclear magnetic resonance (1H- and 13C- NMR), fourier transform infrared (FTIR) and mass (LC-ESI-MS/MS) spectroscopic methods. Density Functional Theory (DFT) calculations for compound I were performed at B3LYP/6-311++G(d,p) level. Optimized geometry, frontier molecular orbitals (HOMO; highest occupied molecular orbital; LUMO: lowest unoccupied molecular orbital), IR and NMR parameters of compound I were obtained. The evaluations reveal that the calculation results support the experimental results. The inhibition effects of compound I on cholinesterases and GST enzyme were investigated. Ki and inhibition concentration (IC50) values were calculated separately. Ki values of compound I were found for GST 14.19 ± 2.15, for AChE 11.13 ± 1.22 and for BChE 8.74 ± 0.76 recpectively. The docking analysis of compound I supported the enzym inhibition activity exhibiting high inhibition constant and binding energy for three receptors. Compound I is strongly bound to AChE, huBChE and Glutathione S-transferase with binding energies -11.24, -8.56 and -10.39 kcal/mol, respectively.Communicated by Ramaswamy H. Sarma.

Abstract
Glutathione s-transferase (GST) is a class of enzymes that performs a wide array of biological functions. However, GST enzymes are most famously known for their roles in catalyzing the conjugation of reduced glutathione (GSH) to electrophilic centers on a wide variety of substrates to induce water-solubility to compounds as a protective antioxidant mechanism against toxic substances. In the present study, in vitro inhibition effects of coumarin, ascorbic acid, sodium sulfide, sodium azide, citric acid compounds, and Cd2+, Cu2+, Ni2+, Mg2+ metal ions against GST enzyme were determined. For this aim, the GST enzyme was purified from Vaccinium arctostapylous L. using the glutathione-agarose affinity chromatography and Sephadex G-100 gel filtration steps. The respective metals and chemical compounds were used at different concentrations for measuring their in vitro GST activity effects. The Ki values of these agents were determined as 0.450 ± 0.13, 15.05 ± 7.05, 0.009 ± 0.001, 0.022 ± 0.006, 0.120 ± 0.36, 0.150 ± 0.06, 0.223 ± 0.03, 0.002 ± 0.0003, and 0.136 ± 0.06 mM, respectively. Finally, the molecular docking interactions of the compounds with the GST target enzyme were evaluated using Autodock Tools-1.5.6. The effective molecular interactions of coumarin, citric acid, ascorbic acid, and sodium sulfide with GST target enzyme were found with their binding lowest energy affinities -4.62, -3.04, -2.53, and -1.67 kcal/mol, respectively.Communicated by Ramaswamy H.

Abstract
In this study, a series of novel Schiff bases (4a-4h) containing 1,2,4-triazole structure were synthesized through a condensation reaction of 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones with 3-(4-methylbenzenesulfonyloxy)-benzaldehyde. The structures of 3-alkyl(aryl)-4-[3-(4-methylsulfonyloxy)-benzylidenamino]-4,5-dihydro-1H-1,2,4-triazol-5-ones (4a-h) were determined through a range of spectroscopic techniques (FT-IR, 1H NMR, 13C NMR, and elemental analysis). In addition, enzyme inhibitory properties of the newly synthesized Schiff bases were determined against acetylcholinesterase (AChE). Their Ki values were calculated in the range of 0.70 ± 0.07-8.65 ± 5.6 µM. Besides, their IC50 values were calculated in the range of 0.43-3.87 µM. Finally, in silico molecular docking interactions of the compounds with AChE target enzyme (PDB ID:4EY7) were evaluated using Chimera and AutoDock Vina softwares. The lowest binding energy levels (-12.0 kcal/mol) of the compounds 4e and 4g with AChE target enzyme were verified the best binding affinities and molecular interactions.Communicated by Ramaswamy H.

Abstract
Schiff bases are well-known compounds for having significant biological properties. In this study, a new Schiff base ligand and its metal complexes were synthesized, and their antioxidant and enzyme inhibitory activities were evaluated. The new Schiff base ligand was synthesized with the condensation reaction of 6-tert-butyl 3-ethyl 2-amino-4,5-dihydrothieno[2,3-c]pyridine-3,6(7H)-dicarboxylate and 2-hydroxybenzaldehyde compounds. Fe(II), Co(II), and Ni(II) metal complexes of the novel Schiff base ligand were synthesized and characterized. The purity and molecular formula of the synthesized compounds were identified with elemental analysis, infrared, ultraviolet-visible, mass spectrophotometry, powder XRD, magnetic and thermal measurements. The Schiff base acted as a three dentate chelate. The analytical and spectroscopic data suggested an octahedral geometry for the complexes. The in vitro antioxidant method studies elucidated a more effective antioxidant character of the Schiff base ligand than its metal complexes but a less effective antioxidant potential than the standard antioxidant compounds. The enzyme inhibition potentials of the synthesized compounds for AChE, BChE, and GST enzymes were determined by in vitro enzyme activity methods. The Schiff base ligand was discovered to be the best inhibitor for the AChE and BChE with the values of 7.13 ± 0.84 µM and 5.75 ± 1.03 µM Ki, respectively. Moreover, the Fe(II) complex displayed the best Ki value as 9.37 ± 1.06 µM for the GST enzyme. Finally, molecular docking studies were carried out to see the structural interactions of the compounds. The metal complexes demonstrated better binding affinities with the AChE, BChE, and GST enzymes than the Schiff base ligand. This study identified a potential Schiff base molecule against both AChE and BChE targets to further investigate for in vivo and safety evaluation.

Abstract
Daucus carota L. ssp. major (DCM) plant is widely used in traditional medicine to treat some types of cancer and various diseases. Therefore, we evaluated the biological activities of this plant to define its effects against prostate cancer (PCa), Alzheimer's disease (AD), oxidation, and diabetes mellitus (DM) as well as identified its phenolic composition. To determine the anti-cancer properties of the plant extract, we treated PCa cells with the extract at a concentration range of 0.25, 0.5, 1, 2, and 4 mg/ml. Significant results were obtained against the PC3 cells compared to normal PNT1a prostate epithelial cells. As a result of precise measurements at the millimolar level, it was observed that the plant extract showed an effective inhibition (IC50 ) against glutathione S-transferase (GST; 12.84 mM), acetyl cholinesterase (AChE; 15.07 mM), and α-Gly (11.75 mM) enzymes when compared with standard inhibitors. Antioxidant activities of DCM methanol extract were determined via two well-known in vitro techniques. The extracts showed antioxidant activities against the DPPH and ABTS+ . The LC-ESI-MS/MS was used to determine the phenolic compounds of methanol extract from DCM. Chlorogenic acid (2,089.096 µg/g), shikimic acid (193.14 µg/g), and coumarin (113.604 µg/g) were characterized as major phenolic compounds. In addition, the interactions of chlorogenic acid, chrysin, coumarin, and shikimic acid with the used three enzymes have been calculated using molecular docking simulation. PRACTICAL APPLICATIONS: Plant natural phenolic compounds have protective effects such as anti-inflammatory, antioxidant, anticarcinogen, and enzyme inhibitory. Therefore, it has an important place in the food and pharmaceutical industry. The present study aims to reveal the enzyme inhibitory, antioxidant, and anticarcinogenic properties of the Daucus carota ssp. Major (DCM) plant extract. Significant results were obtained against the PC3 cells compared to normal PNT1a prostate epithelial cells. DCM extract demonstrated considerable antioxidant activity and inhibitory potential on used metabolic enzymes. These biological effects are thought to have a relationship with rich chemical composition.

Abstract
In the present study, 3-substitued-4-(4-hydroxybenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones (S1-8) were synthesized by treating 4-hydroxybenzaldehyde (B) with eight different 3-substitued-4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones (T1-8) in acetic acid medium, separately. The synthesized Schiff bases (S) were reacted with formaldehyde and secondary amine such as 4-piperidinecarboxyamide to afford novel heterocyclic bases. 3-Substitued-4-(4-hydroxybenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones (T) were treated with 4-piperidinecarboxyamide in the presence of formaldehyde to synthesize eight new 1-(4-piperidinecarboxyamide-1-yl-methyl)-3-substitued-4-(4-hydroxybenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones (M1-8). The structure characterization of compounds was carried out using 1 H-NMR, IR, HR-MS, and 13 C-NMR spectroscopic methods. The inhibitory properties of the newly synthesized compounds were calculated against the acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and glutathione S-transferase (GST) enzymes. Ki values were calculated in the range of 20.06±3.11-36.86±6.17 μM for GST, 17.87±2.91-30.53±4.25 μM for AChE, 9.08±0.69-20.02±2.88 μM for BChE, respectively, Besides, IC50 values were also calculated. Best binding scores of -inhibitors against used enzymes were calculated as -12.095 kcal/mol, -12.775 kcal/mol, and -9.336 kcal/mol, respectively. While 5-oxo-triazole piperidine-4-carboxamide moieties have a critical role in the inhibition of AChE and GST enzymes, hydroxy benzyl moiety is important for BChE enzyme inhibition.

Abstract
Sulfonamide derivatives exhibit a wide biological activity and can function as potential medical molecules in the development of a drug. Studies have reported that the compounds have an effect on many enzymes. In this study, the derivatives of amine sulfonamide (1i-11i) were prepared with reduced imine compounds (1-11) with NaBH4 in methanol. The synthesized compounds were fully characterized by spectral data and analytical. The effect of the synthesized derivatives on acetylcholinesterase (AChE), glutathione S-transferase (GST) and α-glycosidase (α-GLY) enzymes were determined. For the AChE and α-GLY, the most powerful inhibition was observed on 10 and 10i series with KI value in the range 2.26 ± 0.45-3.57 ± 0.97 and 95.73 ± 13.67-102.45 ± 11.72 µM, respectively. KI values of the series for GST were found in the range of 22.76 ± 1.23-49.29 ± 4.49. Finally, the compounds have a stronger inhibitor in lower concentrations by the attachment of functional electronegative groups such as two halogens (-Br and -CI), -OH to the benzene ring and -SO2NH2. The crystal structures of AChE, α-GLY, and GST in complex with selected derivatives 4 and 10 show the importance of the functional moieties in the binding modes within the receptors.Communicated by Ramaswamy H.

Abstract
Many plant species have a large diversity of secondary metabolites with different biological activities. This study aims to assess the phenolic constituent, enzyme inhibitory and antioxidant activities of the aqueous (water) and methanol extracts of Inula discoidea. The enzyme assays showed effective enzyme inhibition of the methanol extract against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), glutathione S-transferase (GST), and α-glycosidase (α-Gly) enzymes. The IC50 values for AChE, BChE, GST, and α-Gly were found as 38.5 mg/mL, 34.65 mg/mL, 77.0 mg/mL, and 40.76 mg/mL, respectively. Antioxidant properties of the aqueous and methanol extracts of I. discoidea were determined by four well-known in vitro techniques (ABTS, CUPRAC, DPPH, and FRAP methods). The antioxidant values of both water and methanol extracts were found to be better than the standard antioxidants (BHA, BHT, ascorbic acid, and α-tocopherol) in ABTS and CUPRAC methods. According to an updated LC-MS/MS technique analysis, quinic acid (21.08 mg/g), protocatechuic acid (4.49 mg/g), and gallic acid (0.48 mg/g) were found as major phenolic compounds of the plant extract. The binding interactions of major phenolic compounds of I. discoidea with the AChE, BChE, GST, and α-Gly enzymes were investigated by the molecular docking studies.

Abstract
Benzimidazole, an anthelmintic used in the manufacture of human and veterinary drugs, is an important heterocyclic compound. In this work, I investigated the effect of drugs such as ricobendazole, thiabendazole, albendazole, and oxfendazole, on Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE) enzyme activity. As kinetic studies, Ki and IC50 values were calculated separately for each drug, respectively. Study findings have shown that benzimidazoles inhibit both AChE and BChE enzymes at the nanomolar level. The compound that best was inhibited the AChE enzyme ricobendazole, and it was that the best inhibited the BChE enzyme thiabendazole. IC50 and Ki values were calculated 123.02 nM, 28.68 ± 8.46 nM for AChE and 64.26 nM, 12.08 ± 2.18 nM for BChE respectively. The types of inhibition indicated by the drugs were investigated and they were found to show non-competitive inhibition.

Abstract
Whether testicular toxicity is mediated by matrix metalloproteinases (MMPs) is an important question that has not been examined. This study investigated the suppressive effect of curcumin and caffeic acid phenethyl ester (CAPE) on oxidative stress, apoptosis, and whether MMPs mediate doxorubicin (DOX)-induced testicular injury. Male rats were randomly divided into eight groups (n = 8 per group). The groups were as follows: sham, dimethyl sulphoxide (100 µL), DOX (3 mg/kg), CAPE (2.68 mg/kg), curcumin (30 mg/kg), DOX+CAPE (3 mg/kg DOX and 2.68 mg/kg CAPE), DOX+curcumin (3 mg/kg DOX and 30 mg/kg curcumin) and DOX+CAPE+curcumin (3 mg/kg DOX, 2.68 mg/kg CAPE and 30 mg/kg curcumin). Injections were administered daily for 21 days. The oxidative stress, MMPs, proinflammatory cytokines and apoptotic markers in the DOX group were higher than the sham group (p < .05); these measures were lower in the groups treated with CAPE and curcumin together with DOX compared with the DOX group (p < .05). The results showed that MMPs mediated DOX-induced testicular injury, but CAPE and especially curcumin suppressed testis injury and cell apoptosis by suppressing DOX-induced increases in MMPs, oxidative stress and proinflammatory cytokines. However, curcumin exhibited more pronounced effects than CAPE in terms of all studied parameters.

Abstract
The compounds (3-6) used in this study were re-synthesized in accordance with our previous study. The inhibitory effect of the complexes on some metabolic enzymes was examined and it was demonstrated that the enzymes inhibited by ligands and their complex molecules at micromolar level. The best Ki value for α-glycosidase enzyme was absorved 1.01±0.08 µM for compound 6. The biological activity of ligand and metal complexes against enzymes was compared with molecular docking method. The enzymes used against ligand and metal complexes respectively: Achethylcholinesterase for ID 4M0E (AChE), butyrylcholinesterase for ID 5NN0 (BChE), α-glycosidase for ID 1XSI (α-Gly). ADME analysis was performed to examine the drug properties of the compounds (3-6). Besides, the anticancer properties of the complexes were studied. The doses of all compounds caused significant reductions in MCF-7 cell viability. The 3 and 5 compounds administered to PC-3 cells exhibited a more pronounced cytotoxic effect than the other two compounds (4 and 6). Furthermore, antibacterial activities of these compounds against Escherichia coli and Staphylococcus aureus were examined.Communicated by Ramaswamy H. Sarma.

Abstract
Nowadays, inhibition of acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and glutathione S-transferases (GSTs) have been a very crucial issue for pharmacological treatments of several disasters. Herein, we investigated inhibition effects of Tamoxifen (TAM), Isoprenaline (ISO), Chlorpromazines (CPZ) and Carbamazepine (CBZ) on GST, AChE, BChE and then molecular structures and active sides of the tested drugs by molecular docking process. The enzyme activity results showed that nearly the whole tested drugs inhibited GST, BChE, AChE efficiently. Chlorpromazine was found to be the best inhibitor for the GST enzyme and the Ki value of this drug was found to be 42.83 ± 8.52 nM. Besides, Isoproterenol drug with the Ki value of 51.80 ± 9.44 nM was found to be the most effective inhibitor on the AChE enzyme. Molecular docking studies showed that the receptor-binding sites of GST, AChE, and BChE were found to 1.069, 1.090, and 1.15 of Sitecore and 0.992, 1.113, and 1.217 of Dscore, respectively. The method was validated by doing validation studies and these validations revealed that re-docked ligands located a very closed position with co-crystallized ligand into the active site for all receptors. Calculation studies for determining the possible enzyme inhibition mechanism with the used drugs revealed that amino and aromatic ring in the structure of the drugs used are effective in inhibition reactions.Communicated by Ramaswamy H.

Abstract
Achillea schischkinii Sosn. is an endemic plant species and it belongs to Asteraceae family. It is distributed widely in the Central and East Anatolia. This study was carried out for evaluation of the antioxidant activity, enzyme inhibition effect, elemental and phenolic content of A. schischkinii. Briefly, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-glycosidase (α-Gly), and glutathione S-transferase (GST) enzymes were strongly inhibited by A. schischkinii. IC50 values for AChE, BChE, α-Gly, and GST enzymes were found as 19.3 mg/mL, 15.4 mg/mL, 69.3 mg/mL, and 34.7 mg/mL respectively. The antioxidant activity of the sample was evaluated by four different in vitro bioanalytical methods. Besides, the concentrations of twelve elements in A. schischkinii were analyzed by ICP-MS technique. Zn (50.6 ppm), Mn (23.0 ppm), and Cu (12.7 ppm) were found as major elements. Furthermore, catechin (20.8 µg/mg extract), trans-ferulic acid (18.3 µg/mg extract), and gallic acid (11.2 µg/mg extract) were characterized as major phenolic compounds by using HPLC. PRACTICAL APPLICATIONS: Acetylcholinesterase, butyrylcholinesterase, α-glycosidase, and glutathione s-transferase enzymes have crucial functions on metabolism. Enzyme inhibition or activation mostly attributed to some health disorders such as Alzheimer's disease, Diabetes mellitus, cancer and hyperglycemia. Phenolic contents are responsible for effective biological activity. This study evaluated the phenolic content and antioxidant activity of Achillea schischkinii as well as the inhibition effect against four metabolic enzymes. The results would be beneficial for using the plant in the food industry and pharmacological process.

Abstract
OBJECTIVES The aim of this study was to investigate whether some of the cephalosporin group antibiotics have inhibition effects on GR and GST enzymes with important functions in the metabolic pathway. METHODS In this study, some selected cephalosporin group antibiotics on GST and GR enzyme was carried out using 96 rats. 16 groups (16 × 6) were created from these rats, divided to another 4 groups (4 × 24). The resulting groups were named as sham groups, cefazolin groups, cefuroxime groups and cefoperazone groups, respectively. The antibiotics used were injected to cefazolin, cefuroxime and cefoperazone groups. The inhibition effects of the antibiotics were measured in the different time intervals (1st, 3th, 5th, 7th). The statistical investigation of the results was performed using the SPSS software program. RESULTS Results revealed the complex effects of the tested substances on GR and GST activity at different time intervals and in different tissues (p < 0.05). This indicated that the tested substances could be exposed to different interactions in vivo. CONCLUSION The tested antibiotics showed some significant inhibition effects on the GST and GR enzyme activity in some tissues of brain, eye and muscle. The interaction of enzyme - the drug is a key factor to highlight the toxicological mechanism. For this reason, the results obtained from in vivo experiments are crucial to explane the physiological properties of the enzymes.

Abstract
BACKGROUND Glutathione S-transferase (GST) and acetylcholinesterase (AChE) are important enzymes in the metabolism. GSTs are primarily available in phase II metabolism. AChE is vital for neurodegenerative disorders. SUBJECTS AND METHODS The in vitro and in vivo effects of cefoperazone sodium (CFP), cefuroxime (CXM), and cefazolin (CZO) were investigated on GST and AChE activity in the present study. GST was purified using Glutathione-Agarose affinity chromatography. RESULTS Ki constants of CFP, CXM, and CZO were 0.1392 ± 0.02, 1.5179 ± 0.33, and 1.006 ± 0.11 mM for GST and 0.3010 ± 0.07, 0.3561 ± 0.09, and 0.3844 ± 0.04 mM, for AChE, respectively. The most effective inhibitor was CFP for both enzymes in in vitro. CZO (50 mg/kg), CXM (25 mg/kg), and CFP (100 mg/kg) inhibit in vivo GST and AChE activities. CXM had the most effective in vivo inhibition on AChE and GST. CONCLUSIONS CZO, CXM, and CFP are effective AChE and GST inhibitors in both in vitro and in vivo.

Abstract
Antioxidant enzymes play an important role in body defense and free radical removal. Cephalosporins are β-lactam antibiotics. In this work, the effects of cefazolin, cefuroxime and cefoperazone which are cephalosporins on some selected antioxidant enzyme and levels of malondialdehyde (MDA) as lipid peroxidation product were investigated in kidney, liver, and brain tissues of albino female rats. Ninety-six albino rats were randomly divided into 16 groups of equal number (n = 6). 50 mg/kg cefazolin, 25 mg/kg cefuroxime, and 100 mg/kg cefoperazone were injected intraperitoneally to the groups (5th-8th and 9th-12th, and 13th-16th groups), respectively. The changes in glutathione reductase (GR), glutathione S-transferase (GST), superoxide dismutase (SOD), peroxidase (POD), and glutathione peroxidase (GSH-Px) levels were studied in each time point group and a time-dependent manner (at the 1st, 3rd, 5th and 7th hour). In addition, MDA levels were examined in all the tissues. The drugs evaluated in this study had different effects on the same enzyme in different tissues depending on time. MDA levels especially in cefazolin and cefoperazone experiments were lower in all the tissues; however, MDA levels were higher in brain and kidney tissues in the cefuroxime groups in a time-dependent manner (p < 0.05). These results revealed the complex effects of the tested drugs on different tissues at different time points. Therefore, the dose and use of these drugs should be adjusted correctly.

Abstract
Multiple studies have been recorded on the synthesis and design of multi-aim anti-Alzheimer molecules. Using dual butyrylcholinesterase/acetylcholinesterase inhibitor molecules has attracted more interest in the therapy for Alzheimer's disease. In this study, a tannic acid compound showed excellent inhibitory effects against acetylcholine esterase (AChE), α-glycosidase, α-amylase, and butyrylcholinesterase (BChE). IC50 values of tannic acid obtained 11.9 nM against α-glycosidase and 3.3 nM against α-amylase, respectively. In contrast, Ki values were found of 50.96 ± 2.18 µM against AChE and 53.17 ± 4.47 µM against BChE. α-Glycosidase inhibitor compounds can be utilized as a novel group of antidiabetic drugs. By competitively decreasing glycosidase activity, these inhibitor molecules help to hamper the fast breakdown of sugar molecules and thereby control the blood sugar level.

Abstract
Pesticides cause pollution by remaining in water, soil, fruits and vegetables for a long time and also reach human through the food chain. It was thought that some pesticides used in agriculture could adversely affect the antioxidant enzyme system and the minimum inhibition values were studied. glutathione s-transferase (GST), an important antioxidant enzyme, catalyzes the conjugation of glutathione with toxic metabolites. It was purified from the blueberry fruits. The purification of the enzyme was performed separately by affinity and gel filtration chromatography. The purity of the enzyme was determined by SDS-PAGE electrophoresis. Characterization studies were done for the enzyme. For this purpose, optimal pH, temperature, Km and Vmax values for GSH and CDNB were also determined for the enzyme as 7.2 in K-phosphate buffer, 50 °C, 1.0 M, 7.0 in K-phosphate buffer, 1.57 mM; 0.17 mM and 0.048 EU/mL, 0.0159 EU/mL, respectively. Additionally, inhibitory effects of some pesticides; dichlorvos, acetamiprid, cyhalothrin, haloxyfop-p-Methyl, 2,4 dichlorophenoxy acetic acid, cypermethrin, imidacloprid, fenoxaprop-p-ethyl, glyphosate isopropylamine salt were examined the enzyme activity in vitro by performing Lineweaver–Burk graphs and plotting activity % IC50 and Ki values were calculated for each of pesticides. All of the pesticides inhibited the GST enzyme at millimolar level. Pesticide showing the best inhibitory effect was found as dichlorvos. The Ki value which is the inhibition constant of this pesticide was 0.0175 ± 0.005.
