Abstract
Diabetes is a chronic metabolic disease caused by insufficient insulin secretion and insulin resistance. Natural product is one of the most important resources for anti-diabetic drug. However, due to the extremely complex composition, this research is facing great challenges. After the advent of ligand fishing technology based on enzyme immobilization, the efficiency of screening anti-diabetic components has been greatly improved. In order to provide critical knowledge for future research in this field, the application progress of immobilized enzyme in screening anti-diabetic components from complex natural extracts in recent years was reviewed comprehensively, including novel preparation technologies and strategies of immobilized enzyme and its outstanding application prospect in many aspects. The basic principles and preparation steps of immobilized enzyme were briefly described, including entrapment, physical adsorption, covalent binding, affinity immobilization, multienzyme system and carrier-free immobilization. New formatted immobilized enzymes with different carriers, hollow fibers, magnetic materials, microreactors, metal organic frameworks, etc., were widely used to screen anti-diabetic compositions from various natural products, such as Ginkgo biloba, Morus alba, lotus leaves, Pueraria lobata, Prunella vulgaris, and Magnolia cortex. Furthermore, the challenges and future prospects in this field were put forward in this review.

La Ferla B, D’Orazio G. Pyranoid Spirosugars as Enzyme Inhibitors. Curr Org Synth 2021; 18:3-22. [DOI: 10.2174/1570179417666200924152648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 08/25/2020] [Accepted: 08/31/2020] [Indexed: 11/22/2022]
Abstract
Background:
Pyranoid spirofused sugar derivatives represent a class of compounds with a significant
impact in the literature. From the structural point of view, the rigidity inferred by the spirofused entity has made
these compounds object of interest mainly as enzymatic inhibitors, in particular, carbohydrate processing enzymes.
Among them glycogen phosphorylase and sodium glucose co-transporter 2 are important target enzymes
for diverse pathological states. Most of the developed compounds present the spirofused entity at the C1 position
of the sugar moiety; nevertheless, spirofused entities can also be found at other sugar ring positions. The main
spirofused entities encountered are spiroacetals/thioacetals, spiro-hydantoin and derivatives, spiro-isoxazolines,
spiro-aminals, spiro-lactams, spiro-oxathiazole and spiro-oxazinanone, but also others are present.
Objectives:
The present review focuses on the most explored synthetic strategies for the preparation of this class
of compounds, classified according to the position and structure of the spirofused moiety on the pyranoid scaffold.
Moreover, the structures are correlated to their main biological activities or to their role as chiral auxiliaries.
Conclusion:
It is clear from the review that, among the different derivatives, the spirofused structures at position
C1 of the pyranoid scaffold are the most represented and possess the most relevant enzymatic inhibitor activities.
Nevertheless, great efforts have been devoted to the introduction of the spirofused entity also in the other positions,
mainly for the preparation of biologically active compounds but also for the synthesis of chiral auxiliaries
useful in asymmetric reactions; examples of such auxiliaries are the spirofused chiral 1,3-oxazolidin-2-ones and
1,3-oxazolidine-2-thiones.

Abstract
The flower of S. japonica is a favorite food and used as traditional medicine. In the present study, a facile and effective method based on the changes in the composition before and after the enzyme reaction was established to screen the active compounds from complex natural products. The separation of an active compound from the ethanolic extracts of Sophora japonica var. violacea, which exhibited the α-amylase inhibitory activity is presented as an example. The analysis of HPLC showed that one component was reduced by 25% after the enzyme reaction. The potential active compound was isolated via LH-20 gel permeation chromatography and identified as kaempferol 3-O-α-l-rhamnopyranosyl-(1 → 6)-β-d-galactopyranosyl-7-O-α-l-rhamnopyranoside by 1H and 13C NMR. The in vitro test indicated that the compound had the α-amylase inhibitory activity, and the IC50 was 88.56 ± 0.60 μg mL-1. The molecular docking study of this compound showed that the compound enfolded in the active sites of α-amylase completely and interacted with the amino acid residues through hydrogen bonds, van der Waals force and hydrophobic interactions.

Abstract
The α-Amylase and α-glucosidase are two main enzymes involved in carbohydrate metabolism. This study was aimed at detecting alpha-amylase inhibitory activity from edible mushroom mycelia. Oyster mushroom was collected from a natural source, from Indian Institute of Technology (Banaras Hindu University) campus and was maintained in vitro in mycelial form. Chloroform, acetone, methanol, and water were used separately for extraction of an active constituent from mycelial cells grown, for 7 days, in potato dextrose broth. The extracts were tested for alpha-amylase inhibitory activity. Chloroform, acetone, and methanol extracts were found to have alpha-amylase inhibitory activity, with IC50 values of 1.71, 224, and 383 μg/mL, respectively. Aqueous extract had no enzyme inhibitory activity. The acetone extract inhibited α-amylase non-competitively whereas chloroform extract showed competitive inhibition. Acetone extraction yielded highest total phenolic content (TPC) of 0.524 mM of gallic acid equivalent, whereas chloroform extraction resulted in lowest TPC of 0.006 mM. The HPLC and absorbance maxima of acetone and chloroform extracts suggest that the bioactive component responsible for enzyme inhibition could be glycoproteins in chloroform extract and catechins (flavonoids) in acetone extract. Thus, the mushroom mycelia under study may be exploited for production and purification of a lead compound for the development of the α-amylase inhibitory drug.

Abstract
α-Amylase inhibitors play an important role in management of diabetes and obesity. In order to rapidly discover potent α-amylase inhibitors from medicinal plants, a ligands-screening method based on enzyme-immobilized magnetic nanoparticles integrated with HPLC was developed. Amine-terminated magnetic nanoparticles were prepared for the immobilization of α-amylase. Based on the affinity theory, the α-amylase-coated magnetic nanoparticles were employed to fish out the ligands from the extracts of Garcinia xanthochymus, and the elutes were examined by HPLC. As a result, three ligands were screened out. Isolation and identification were carried out subsequently. By analyzing the UV, MS and NMR spectra, they were identified as three biflavonoids including GB2a glucoside (2), GB2a (3) and fukugetin (4). The IC50 values of the three compounds were also determined. The results suggest the proposed approach is efficient and accurate, and has great potential in rapid discovery of drug candidates from medical plants.

Abstract
Key to the development of a useful clinical therapy is the minimization of side effects. Routine safety testing, however, does not provide information about the physiological status of many potentially useful gene transfer target sites. In this study, we evaluated the longitudinal effects of intrasalivary duct delivery of recombinant serotype 5 adenoviral (rAd5; 10(9)-10(10) particles/gland in rats) and recombinant serotype 2 adeno-associated viral (rAAV2; 10(8)-10(9) particles/gland in mice) vectors on salivary composition. Both vectors led to modest, transient alterations in several salivary components that thereafter returned to normal. The changes suggested two initial specific consequences of rAd5 and rAAV2 vector administration: (1) a modest breach of the mucosal barrier in the targeted glands, indicated by elevations in salivary albumin, total protein, and Na+ levels, and (2) an innate host response, indicated by transient elevations in either salivary lactoferrin and IgA levels (rAd5) or mucin (rAAV2). These studies are consistent with the notion that administration of modest doses of rAd5 and rAAV2 vectors to salivary glands for a therapeutic purpose can be accomplished without severe or permanent injury to the target tissue, or compromise to its essential exocrine physiological function.

Abstract
Conidia of Trichoderma harzianum F-340, an active producer of fungal mutanase, were mutagenized with physical and chemical mutagens used separately or in combination. After mutagenesis, the drop in conidia viability ranged from 0.004% to 71%. Among the applied mutagens, nitrosoguanidine gave the highest frequency of cultures with enhanced mutanase activity (98%). In total, 400 clones were isolated, and preliminarily evaluated for mutanase activity in flask microcultures. Eight most productive mutants were then quantified for mutanase production in shake flask cultures. The obtained results fully confirmed a great propensity of all the tested mutants to synthesize mutanase, the activity of which increased from 59 to 107% in relation to the parental T. harzianum culture. The best mutanase-overproducing mutant (T. harzianumn F-340-48), obtained with nitrosoguanidine, produced the enzyme activity of 1.36 U/ml (4.5 U/mg protein) after 4 days of incubation in shake flask culture. This productivity was almost twices higher than that achieved by the initial strain F-340, and, at present, is the best reported in the literature. The potential application of mutanase in dentistry is also discussed.

Abstract
This study is the first report on the effectiveness and specificity of alpha-acarviosinyl-(1-->4)-alpha-D-glucopyranosyl-(1-->6)-D-glucopyranosylidene-spiro-thiohydantoin (PTS-G-TH) inhibitor on the 2-chloro-4-nitrophenyl-4-O-beta-D-galactopyranosyl-maltoside (GalG2CNP) and amylose hydrolysis catalysed by human salivary alpha-amylase (HSA). Synthesis of PTS-G-TH was carried out by transglycosylation using acarbose as donor and glucopyranosylidene-spiro-thiohydantoin (G-TH) as acceptor. This new compound was found to be a much more efficient HSA inhibitor than G-TH. The inhibition is a mixed-noncompetitive type on both substrates and only one molecule of inhibitor binds to the enzyme. Kinetic constants calculated from secondary plots are in micromolar range. Values of K(EI) and K(ESI) are very similar in the presence of GalG2CNP substrate; 0.19 and 0.24 microM, respectively. Significant difference can be found for K(EI) and K(ESI) using amylose as substrate; 8.45 and 0.5 microM, respectively. These values indicate that inhibition is rather uncompetitive than competitive related to amylose hydrolysis.

Abstract
Synthesis of acarviosinyl-isomaltosyl-spiro-thiohydantoin in yields up to 20%, has been achieved by Bacillus stearothermophilus maltogenic amylase (BSMA). BSMA is capable of transferring the acarviosine-glucose residue from an acarbose donor onto glucopyranosylidene-spiro-thiohydantoin. Reactions were followed using HPLC and MALDI-TOF MS. 1H and 13C NMR studies revealed that the enzyme reserved its stereoselectivity. Glycosylation took place mainly at C-6 resulting in alpha-acarviosinyl-(1-->4)-alpha-D-glucopyranosyl-(1-->6)-D-glucopyranosylidene-spiro-thiohydantoin. This compound was found to be a much more efficient salivary amylase inhibitor than glucopyranosylidene-spiro-thiohydantoin with kinetic constants of K(EI)=0.19 microM and K(ESI)=0.24 microM.
