Structure-Activity Relationship of Methyl 4-Aminobenzoate Derivatives as Being Drug Candidate Targeting Glutathione Related Enzymes: in Vitro and in Silico Approaches.

A thiol compound, glutathione, is essential for healthy cell defence against xenobiotics and oxidative stress. Glutathione reductase (GR) and glutathione S-transferase (GST) are two glutathione-related enzymes that function in the antioxidant and the detoxification systems. In this study, potential inhibitory effects of methyl 4-aminobenzoate derivatives on GR and GST were examined in vitro.

Affinity-based and in a single step purification of recombinant horseradish peroxidase A2A isoenzyme produced by Pichia pastoris.

Horseradish peroxidase (HRP) is an oxidoreductase enzyme and oxidizes various inorganic and organic compounds. It has wide application areas such as immunological tests, probe-based test techniques, removal of phenolic pollutants from wastewater and organic synthesis. HRP is found in the root of the horseradish plant as a mixture of different isoenzymes, and it is very difficult to separate these enzymes from each other.

Inhibition Profiles and Molecular Docking Analysis of Benzohydrazide Derivatives on Red Blood Cell Carbonic Anhydrases Isozymes.

Background: Carbonic anhydrases (CAs, EC 4.2.1.

Methyl benzoate derivatives as inhibitors of pentose phosphate pathway, which promotes cancer progression and drug resistance: An in silico study supported by in vitro results.

The pentose phosphate pathway (PPP), whose products are vital in biosynthetic events, is targeted in the treatment of many diseases such as cancer and malaria. The objective of this study was to identify new PPP inhibitors. The inhibition effects of methyl 4-amino benzoates on glucose 6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD) were analyzed through in vitro experiments and molecular docking studies were used to estimate inhibition mechanisms.

Molecular docking and inhibition profiles of some antibiotics on lactoperoxidase enzyme purified from bovine milk.

Antibiotics are generally used for human and veterinary applications to preserve and to control microbial diseases. Milk has a biologically significant enzyme known as lactoperoxidase (LPO) that is a member of peroxidase family. In metabolism, LPO has ability to catalyze the transformation of thiocyanate (SCN) to hypothiocyanite (OSCN) that is an antibacterial agent and the reaction occurs with hydrogen peroxide.

Lactoperoxidase inhibition of some natural phenolic compounds: Kinetics and molecular docking studies.

The inhibition effects of some phenolic compounds from natural products such as taxifolin, resveratrol, olivetol, cynarine, and phloretin on bovine milk lactoperoxidase (LPO) enzyme were examined. For this aim, LPO was purified by the affinity chromatography technique with a yield of 77.68% in 421.

In vitro effects of standard antioxidants on lactoperoxidase enzyme-A molecular docking approach.

Lactoperoxidase (LPO), an antioxidant enzyme, is a natural antimicrobial system that eliminates the harmful effects of microorganisms in milk. It has a wide range of applications and is also preferred in cosmetic and clinical applications, as well as used in foods. The use of antioxidants is well recognized in the food and feed industries to improve the shelf life of products.

The inhibition effects of some natural products on lactoperoxidase purified from bovine milk.

In this study, inhibition profiles of some natural products, which are digoxin, L-Dopa, dopamine, isoliquiritigenin, and 1,1,2,2-tetrakis(p-hydroxyphenyl)ethane (Tetrakis), were investigated against bovine lactoperoxidase (LPO) enzyme. Digoxin, L-Dopa, and dopamine are active ingredients of some drugs, which have important functions in our body, especially in cases of heart failure. Isoliquiritigenin and tetrakis are types of natural phenolic compounds, which play an important role in cancer prevention and treatment.

Secondary Sulfonamides as Effective Lactoperoxidase Inhibitors.

Secondary sulfonamides (-) incorporating acetoxybenzamide, triacetoxybenzamide, hydroxybenzamide, and trihydroxybenzamide and possessing thiazole, pyrimidine, pyridine, isoxazole and thiadiazole groups were synthesized. Lactoperoxidase (LPO, E.C.

A hierarchical assembly of flower-like hybrid Turkish black radish peroxidase-Cu nanobiocatalyst and its effective use in dye decolorization.

Effective dye decolorization in wastewater still shows a big challenge. Although the biological methods, especially using enzymes, offer alternative and effective process for dye degradation and overcome the limitations of chemical and physical methods such as the instability, lack of reusability and high cost of free enzymes strictly, which limit their use in many scientific and technical applications. Enzymes rapidly lose their activities in aqueous solutions and against environmental changes due to their very susceptibility and unfavorable conformations.

Discovery of Potent Carbonic Anhydrase and Acetylcholinesterase Inhibitors: 2-Aminoindan β-Lactam Derivatives.

β-Lactams are pharmacologically important compounds because of their various biological uses, including antibiotic and so on. β-Lactams were synthesized from benzylidene-inden derivatives and acetoxyacetyl chloride. The inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and acetylcholinesterase (AChE).

Purification of peroxidase from red cabbage (Brassica oleracea var. capitata f. rubra) by affinity chromatography.

Peroxidase was purified in a single step using 4-amino benzohydrazide affinity chromatography from red cabbage (Brassica oleracea var. capitata f. rubra), and some important biochemical characteristics of the purified enzyme were determined.

Single-step purification of peroxidase by 4-aminobenzohydrazide from Turkish blackradish and Turnip roots.

Peroxidases (PODs) were purified from the Turkish blackradish (Raphanus sativus L.) (TBR) and Turnip (Brassica rapa L.) using a simple and effective single-step method.
