Microbial transformation of capsaicin by several human intestinal fungi and their inhibitory effects against lysine-specific demethylase 1. PHYTOCHEMISTRY 2022; 202:113365. [PMID: 35940425 DOI: 10.1016/j.phytochem.2022.113365] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/31/2022] [Accepted: 08/01/2022] [Indexed: 06/15/2023]
Abstract
Capsaicin widely exists in the Capsicum genus (e.g., hot peppers) and is commonly used as a food additive or medicinal material. In this work, microbial transformation of capsaicin was performed based on the three cultivated human intestinal fungi. Fourteen metabolites were obtained, and their chemical structures were elucidated by spectroscopic data analysis, including 13 compounds with undescribed structures. Hydroxylation, lactylation, succinylation, citric acylation, and acetylation were observed for these microbial metabolites derived from capsaicin, which indicated diverse catalytic characteristics of human intestinal fungi. In an in vitro bioassay, four metabolites and capsaicin inhibited the activity of lysine-specific demethylase 1 (LSD1) with a more than 70% inhibitory rate at 10 μM. In particular, 9,5'-dihydroxycapsaicin displayed the strongest inhibitory effect with an IC50 of 1.52 μM. Therefore, capsaicin analogs displayed potential application as LSD1 inhibitors against the invasion and migration of cancer cells.

Abstract
Crystal structures of the UDP glycosyltransferase PaGT3 in complex with various ligands are reported. This study sheds light on how the enzyme accommodates sugar acceptors of different shapes and sizes for successful glycosylation. Capsaicinoids are phenolic compounds that have health benefits. However, the pungency and poor water solubility of these compounds limit their exploitation. Glycosylation is a powerful method to improve water solubility and reduce pungency while preserving bioactivity. PaGT3, a uridine diphosphate glycosyltransferase (UGT) from Phytolacca americana, is known for its ability to glycosylate capsaicinoids and other phenolic compounds. While structural information on several UGTs is available, structures of UGTs that can glycosylate a range of phenolic compounds are rare. To fill this gap, crystal structures of PaGT3 with a sugar-donor analogue (UDP-2-fluoroglucose) and the acceptors capsaicin and kaempferol were determined. PaGT3 adopts a GT-B-fold structure that is highly conserved among UGTs. However, the acceptor-binding pocket in PaGT3 is hydrophobic and large, and is surrounded by longer loops. The larger acceptor-binding pocket in PaGT3 allows the enzyme to bind a range of compounds, while the flexibility of the longer loops possibly plays a role in accommodating the acceptors in the binding pocket according to their shape and size. This structural information provides insights into the acceptor-binding mechanism in UGTs that bind multiple substrates.

Abstract
BACKGROUND Plants are the prime source of vital secondary metabolites (SMs) which are medicinally important for drug development, and these secondary metabolites are often used by plants in the various important tasks like defense against herbivory, interspecies defenses and against different types of stresses. For humans, these secondary metabolites are important as medicines, pigments, flavorings and drugs. Because most of the pharmaceutical industries are highly dependent on medicinal plants and their extraction, these medicinal plants are getting endangered. MAIN BODY Plant cell culture technologies are introduced as a viable mechanism for producing and studying SMs of plants. Various types of in vitro strategies (elicitation, hairy root culture system, suspension culture system, etc.) have been considerably used for the improvement of the production of SMs of plants. For the enhancement of SM production, suspension culture and elicitation are mainly used, but hairy root culture and other organ cultures are proved to satisfy the demand of secondary metabolites. Now, it is easy to control and manipulate the pathways that produce the plant secondary metabolites. CONCLUSIONS Techniques like plant cell, tissue and organ cultures provide a valuable method for the production of medicinally significant SMs. In recent years, most of the in vitro strategies are used due to knowledge and regulation of SM pathway in commercially valuable plants. In future, these things will provide a valuable method to sustain the feasibility of medicinal plants as the renewable sources of medicinally important compounds, and these methods will provide successful production of desired, important, valuable and also unknown compounds.

Abstract
Capsaicinoids are the compounds responsible for the pungency of chili peppers. These substances have attracted the attention of many research groups in recent decades because of their antinociceptive, analgesic, anti-inflammatory, and anti-obesity properties, among others. There are nearly 160 capsaicinoids reported in the literature. Approximately 25 of them are natural products, while the rest are synthetic or semi-synthetic products. A large amount of NMR data for the capsaicinoids is dispersed throughout literature. Therefore, there is a need to organize all this NMR data in a systematic and orderly way. This review summarizes the (1) H and (13) C NMR data on 159 natural and synthetic capsaicinoids, with a brief discussion of some typical and relevant aspects of these NMR data.

Abstract
The development of plant tissue (including organ and cell) cultures for the production of secondary metabolites has been underway for more than three decades. Plant cell cultures with the production of high-value secondary metabolites are promising potential alternative sources for the production of pharmaceutical agents of industrial importance. Medicinal plant cell suspension cultures (MPCSC), which are characterized with the feature of fermentation with plant cell totipotency, could be a promising alternative "chemical factory". However, low productivity becomes an inevitable obstacle limiting further commercialization of MPCSC and the application to large-scale production is still limited to a few processes. This review generalizes and analyzes the recent progress of this bioproduction platform for the provision of medicinal chemicals and outlines a range of trials taken or underway to increase product yields from MPCSC. The scale-up of MPCSC, which could lead to an unlimited supply of pharmaceuticals, including strategies to overcome and solution of the associated challenges, is discussed.

Abstract
Capsaicin β-glucoside was isolated from the feces of Helicoverpa armigera, Helicoverpa assulta, and Helicoverpa zea that fed on capsaicin-supplemented artificial diet. The chemical structure was identified by NMR spectroscopic analysis as well as by enzymatic hydrolysis. The excretion rates of the glucoside were different among the three species; those in the two generalists, H. armigera and H. zea, were higher than in a specialist, H. assulta. UDP-glycosyltransferases (UGT) enzyme activities measured from the whole larval homogenate of the three species with capsaicin and UDP-glucose as substrates were also higher in the two generalists. Compared among five different larval tissues (labial glands, testes from male larvae, midgut, the Malpighian tubules (MT), and fat body) from the three species, the formation of the capsaicin glucoside by one or more UGT is high in the fat body of all the three species as expected, as well as in H. assulta MT. Optimization of the enzyme assay method is also described in detail. Although the lower excretion rate of the unaltered capsaicin in H. assulta indicates higher metabolic capacity toward capsacin than in the other two generalists, the glucosylation per se seems to be insufficient to explain the decrease in capsaicin in the specialist, suggesting that H. assulta might have another important mechanism to deal with capsaicin more specifically.

Abstract
Plant secondary compounds not only play an important role in plant defense, but have been a driving force for host adaptation by herbivores. Capsaicin (8-methyl-N-vanillyl-6-nonenamide), an alkaloid found in the fruit of Capsicum spp. (Solanaceae), is responsible for the pungency of hot pepper fruits and is unique to the genus. The oriental tobacco budworm, Helicoverpa assulta (Lepidoptera: Noctuidae), is a specialist herbivore feeding on solanaceous plants including Capsicum annuum, and is one of a very few insect herbivores worldwide capable of feeding on hot pepper fruits. To determine whether this is due in part to an increased physiological tolerance of capsaicin, we compared H. assulta with another specialist on Solanaceae, Heliothis subflexa, and four generalist species, Spodoptera frugiperda, Heliothis virescens, Helicoverpa armigera, and Helicoverpa zea, all belonging to the family Noctuidae. When larvae were fed capsaicin-spiked artificial diet for the entire larval period, larval mortality increased in H. subflexa and H. zea but decreased in H. assulta. Larval growth decreased on the capsaicin-spiked diet in four of the species, was unaffected in H. armigera and increased in H. assulta. Food consumption and utilization experiments showed that capsaicin decreased relative consumption rate (RCR), relative growth rate (RGR) and approximate digestibility (AD) in H. zea, and increased AD and the efficiency of conversion of ingested food (ECI) in H. armigera; whereas it did not significantly change any of these nutritional indices in H. assulta. The acute toxicity of capsaicin measured by injection into early fifth instar larvae was less in H. assulta than in H. armigera and H. zea. Injection of high concentrations produced abdominal paralysis and self-cannibalism. Injection of sub-lethal doses of capsaicin resulted in reduced pupal weights in H. armigera and H. zea, but not in H. assulta. The results indicate that H. assulta is more tolerant to capsaicin than the other insects tested, suggesting that this has facilitated expansion of its host range within Solanaceae to Capsicum after introduction of the latter to the Old World about 500 years ago. The increased larval survival and growth due to chronic dietary exposure to capsaicin suggests further adaptation of H. assulta to that compound, the mechanisms of which remain to be investigated.

Abstract
The biocatalytic synthesis of xylooligosaccharides of daidzein was investigated using cultured cells of Catharanthus roseus and Aspergillus sp. β-xylosidase. The cultured cells of C. roseus converted daidzein into its 4′-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside, which was a new compound. The 7-O-β-primeveroside of daidzein was further xylosylated by Aspergillus sp. β-xylosidase to daidzein trisaccharide, i.e., 7-O-[6-O-(4-O-(β-d-xylopyranosyl))-β-d-xylopyranosyl]-β-d-glucopyranoside, which was a new compound. The 4′-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside of daidzein exerted DPPH free-radical scavenging and superoxide radical scavenging activity. On the other hand, 7-O-β-glucoside and 7-O-β-primeveroside of daidzein showed inhibitory effects on IgE antibody production.

Their structures were elucidated as 2α,3α,19α-trihydroxy-ursolic acid-28-O-β-d-glucopyranoside (2), 2α,3β,19α-trihydroxy-ursolic acid-28-O-β-d-glucopyranoside (3), oleanolic acid 28-O-β-d-glucopyranosyl ester (4), oleanolic acid-3-O-β-d-glucopyranoside (5), 3-O-(β-d-glucopyranosyl)-oleanolic acid-28-O-β-d-glucopyranoside (6), 2α,3β,19a-trihydroxy-oleanolic acid-28-O-β-d-glucopyranoside (7), 21β-hydroxyl oleanolic acid-28-O-β-d-glucopyranoside (8), 21β-hydroxyl oleanolic acid (9), and 7α,21β-dihydroxyl oleanolic acid (10) based on the extensive NMR studies. Among them, 10 was a new compound and compounds 5 and 8-10 had stronger cytotoxic activities against Hela cell lines than the substrate. At the same time, it was reported for the first time in this paper that the skeletons of compounds 2 and 3 were changed from oleanane to uranane and seven glycosidation products were obtained by biotransformation.

Abstract
Curcumin 4‘- O-glucooligosaccharides were synthesized by a two step-enzymatic method using almond β-glucosidase and cyclodextrin glucanotransferase (CGTase). Curcumin was glucosylated to curcumin 4‘- O-β-D-glucopyranoside by almond β-glucosidase in 19% yield. Curcumin 4‘- O-β-D-glucopyranoside was converted into curcumin 4‘- O-β-glucooligosaccharides, i.e. 4‘- O-β-maltoside (51%) and 4‘- O-β-maltotrioside (25%), by further CGTase-catalyzed glycosylation. Curcumin 4‘- O-β-glycosides showed suppressive action on IgE antibody formation and inhibitory effects on histamine release from rat peritoneal mast cells.

Abstract
Cultured cells of Pavlova sp. glycosylated bisphenol A to its mono-glucoside, 2-(4-beta-D-glucopyranosyloxyphenyl)-2-hydroxyphenylpropane (9%). Use of immobilized Pavlova cells in sodium alginate gel improved yield of the product (17%). On the other hand, Pavlova cell cultures converted benzophenone into diphenylmethanol (49%) and diphenylmethyl beta-D-glucopyranoside (6%). Incubation of benzophenone with immobilized Pavlova cells gave products in higher yields; the yields of diphenylmethanol and diphenylmethyl beta-D-glucopyranoside were 85 and 15%, respectively.

Abstract
Sugar-sugar glycosyltransferases play an important role in structural diversity of small molecule glycosides in higher plants. We isolated a cDNA clone encoding a sugar-sugar glucosyltransferase (CaUGT3) catalyzing 1,6-glucosylation of flavonol and flavone glucosides for the first time from Catharanthus roseus. CaUGT3 exhibited a unique glucosyl chain elongation activity forming not only gentiobioside but also gentiotrioside and gentiotetroside in a sequential manner. We investigated the functional properties of CaUGT3 using homology modeling and site-directed mutagenesis, and identified amino acids positioned in the acceptor-binding pocket as crucial for providing enough space to accommodate flavonoid glucosides instead of flavonoid aglycones. These results provide basic information for understanding and engineering the catalytic functions of sugar-sugar glycosyltransferases involved in biosynthesis of plant glycosides.

Abstract
Fluoroaromatic compounds are used as agrochemicals and released into environment as pollutants. Glycosylation of 2-, 3-, and 4-fluorophenols using plant cell cultures of Nicotiana tabacum was investigated to elucidate their potential to metabolize these compounds. Cultured N. tabacum cells converted 2-fluorophenol into its beta-glucoside (60%) and beta-gentiobioside (10%). 4-Fluorophenol was also glycosylated to its beta-glucoside (32%) and beta-gentiobioside (6%) by N. tabacum cells. On the other hand, N. tabacum glycosylated 3-fluorophenol to beta-glucoside (17%).

Abstract
The sequential glycosylation of a soybean isoflavone, daidzein, with cultured suspension cells of Eucalyptus perriniana and cyclodextrin glucanotransferase was studied. Daidzein was converted into two glycosylation products, daidzein 7-O-beta-D-glucopyranoside (39%) and daidzein 7-O-[6-O-(beta-D-glucopyranosyl)]-beta-D-glucopyranoside (beta-gentiobioside, 6%), by cultured E. perriniana cells. Further glycosylation of daidzein 7-O-beta-glucoside with cyclodextrin glucanotransferase gave daidzein 7-O-[4-O-(alpha-D-glucopyranosyl)]-beta-D-glucopyranoside (beta-maltoside, 26%), daidzein 7-O-beta-maltotrioside (15%), and daidzein 7-O-beta-maltotetraoside (7%).

Abstract
The biotransformation of hesperetin by cultured cells of Ipomoea batatas and Eucalyptus perriniana was investigated. Three glycosides, hesperetin 3'-O-beta-D-glucopyranoside (33 microg/g fr. wt of cells), hesperetin 3',7-O-beta-D-diglucopyranoside (217 microg/g fr. wt of cells), and hesperetin 7-O-[6-O-(beta-D-glucopyranosyl)]-beta-d-glucopyranoside (beta-gentiobioside, 22 microg/g fr. wt of cells), together with three hitherto known glycosides, hesperetin 5-O-beta-d-glucopyranoside (23 microg/g fr. wt of cells), hesperetin 7-O-beta-D-glucopyranoside (57 microg/g fr. wt of cells), and hesperetin 7-O-[6-O-(alpha-L-rhamnopyranosyl)]-beta-D-glucopyranoside (beta-rutinoside, hesperidin, 13 microg/g fr. wt of cells), were isolated from cultured suspension cells of E. perriniana that had been treated with hesperetin. Oligosaccharide chains were regioselectively formed at the C-7 position of hesperetin to afford beta-gentiobioside and beta-rutinoside. On the other hand, cultured I. batatas cells converted hesperetin into hesperetin 3'-O-beta-D-glucopyranoside (60 microg/g fr. wt of cells), hesperetin 5-O-beta-D-glucopyranoside (23 microg/g fr. wt of cells), and hesperetin 7-O-beta-D-glucopyranoside (110 microg/g fr. wt of cells).
