Abstract
The diversity of the biological activity of volatile organic compounds (VOCs), including unsaturated ketone β-ionone, promising pharmacological, biotechnological, and agricultural agent, has aroused considerable interest. However, the functional role and mechanisms of action of VOCs remain insufficiently studied. In this work, the response of bacterial cells to the action of β-ionone was studied using specific bioluminescent lux-biosensors containing stress-sensitive promoters. We determined that in Escherichia coli cells, β-ionone induces oxidative stress (PkatG and Pdps promoters) through a specific response mediated by the OxyR/OxyS regulon, but not SoxR/SoxS (PsoxS promoter). It has been shown that β-ionone at high concentrations (50 μM and above) causes a weak induction of the expression from the PibpA promoter and slightly induces the PcolD promoter in the E. coli biosensors; the observed effect is enhanced in the ΔoxyR mutants. This indicates the presence of some damage to proteins and DNA. β-Ionone was found to inhibit the bichaperone-dependent DnaKJE-ClpB refolding of heat-inactivated bacterial luciferase in E. coli wild-type and ΔibpB mutant strains. In the cells of the Gram-positive bacterium Bacillus subtilis 168 pNK-MrgA β-ionone does not cause oxidative stress. Thus, in this work, the specificity of bacterial cell stress responses to the action of β-ionone was shown.

Abstract
Photoaging is widely regarded as the most significant contributor to skin aging damage. It is triggered by prolonged exposure to ultraviolet (UV) light and typically manifests as dryness and the formation of wrinkles. Nutritional intervention is a viable strategy for preventing and treating skin photoaging. In previous studies, we demonstrated that α-ionone had ameliorating effects on photoaging in both epidermal keratinocytes and dermal fibroblasts. Here, we investigated the potential anti-photoaging effects of dietary α-ionone using a UVB-irradiated male C57BL/6N mouse model. Our findings provided compelling evidence that dietary α-ionone alleviates wrinkle formation, skin dryness, and epidermal thickening in chronic UVB-exposed mice. α-Ionone accumulated in mouse skin after 14 weeks of dietary intake of α-ionone. α-Ionone increased collagen density and boosted the expression of collagen genes, while attenuating the UVB-induced increase of matrix metalloproteinase genes in the skin tissues. Furthermore, α-ionone suppressed the expression of senescence-associated secretory phenotypes and reduced the expression of the senescence marker p21 and DNA damage marker p53 in the skin of UVB-irradiated mice. Transcriptome sequencing results showed that α-ionone modifies gene expression profiles of skin. Multiple pathway enrichment analyses on both the differential genes and the entire genes revealed that α-ionone significantly affects multiple physiological processes and signaling pathways associated with skin health and diseases, of which the p53 signaling pathway may be the key signaling pathway. Taken together, our findings reveal that dietary α-ionone intervention holds promise in reducing the risks of skin photoaging, offering a potential strategy to address skin aging concerns.

Liu Y, Jiang J. Preparation of β-ionone microcapsules by gelatin/pectin complex coacervation. Carbohydr Polym 2023; 312:120839.

Abstract
β-ionone has a unique violet odor and good biological activity, which is an essential fragrance component and potential anticancer drug. In this paper, β-ionone was encapsulated using complex coacervation of gelatin and pectin, followed by cross-linking with glutaraldehyde. The pH value, wall material concentration, core-wall ratio, homogenization conditions, and curing agent content were investigated in the single-factor experiments. For example, the encapsulation efficiency increased with the homogenization speed, which reached a relatively high value at 13000 r/min for 5 min. The gelatin/pectin ratio (3:1, w/w) and pH value (4.23) significantly affected the size, shape, and encapsulation efficiency of the microcapsule. The fluorescence microscope and SEM were used to characterize the morphology of the microcapsules, in which the microcapsule has a stable morphology, uniform size, and spherical multinuclear structure. FTIR measurements confirmed the electrostatic interactions between gelatin and pectin during complex coacervation. Thermogravimetric analysis (TGA) revealed that the microcapsules could maintain good thermal stability over 260 °C. The release rate of β-ionone microcapsule was only 20.6 % after 30 days at the low temperature of 4 °C. These findings provide an effective carrier to deliver flavors like β-ionone and could be useful in the fields of daily chemicals and textiles.

Abstract
PURPOSE We purified and characterized a novel ene-reductase (KaDBR1) from Kazachstania exigua HSC6 for the synthesis of dihydro-β-ionone from β-ionone. METHODS KaDBR1 was purified to homogeneity by ammonium sulfate precipitation and phenyl-Sepharose Fast Flow and Q-Sepharose chromatography. The purified enzyme was characterized by measuring the amount of dihydro-β-ionone from β-ionone with LC-MS analysis method. RESULTS The molecular mass of KaDBR1 was estimated to be 45 kDa by SDS-PAGE. The purified KaDBR1 enzyme had optimal activity at 60 °C and pH 6.0. The addition of 5 mM Mg2+, Ca2+, Al3+, Na+, and dithiothreitol increased the activity of KaDBR1 by 25%, 18%, 34%, 20%, and 23%, respectively. KaDBR1 favored NADH over NADPH as a cofactor, and its catalytic efficiency (kcat/Km) toward β-ionone using NADH was 8.1-fold greater than when using NADPH. CONCLUSION Owing to its unique properties, KaDBR1 is a potential candidate for the enzymatic biotransformation of β-ionone to dihydro-β-ionone in biotechnology applications.

Microorganisms 2023; 11:microorganisms11040872. [PMID: 37110295 PMCID: PMC10146173 DOI: 10.3390/microorganisms11040872] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 03/23/2023] [Accepted: 03/24/2023] [Indexed: 03/31/2023] Open
Abstract
Cyanobacteria commonly form large blooms in waterbodies; they can produce cyanotoxins, with toxic effects on humans and animals, and volatile compounds, causing bad tastes and odors (T&O) at naturally occurring low concentrations. Notwithstanding the large amount of literature on either cyanotoxins or T&O, no review has focused on them at the same time. The present review critically evaluates the recent literature on cyanotoxins and T&O compounds (geosmin, 2-methylisoborneol, β-ionone and β-cyclocitral) to identify research gaps on harmful exposure of humans and animals to both metabolite classes. T&O and cyanotoxins production can be due to the same or common to different cyanobacterial species/strains, with the additional possibility of T&O production by non-cyanobacterial species. The few environmental studies on the co-occurrence of these two groups of metabolites are not sufficient to understand if and how they can co-vary, or influence each other, perhaps stimulating cyanotoxin production. Therefore, T&Os cannot reliably serve as early warning surrogates for cyanotoxins. The scarce data on T&O toxicity seem to indicate a low health risk (but the inhalation of β-cyclocitral deserves more study). However, no data are available on the effects of combined exposure to mixtures of cyanotoxins and T&O compounds and to combinations of T&O compounds; therefore, whether the co-occurrence of cyanotoxins and T&O compounds is a health issue remains an open question.

Abstract
In nature, the odorous substance β-ionone has been widely detected in aquatic ecosystems. However, little is known about its ecotoxicological effects on freshwater vertebrates. In this study, we aimed to assess the acute toxicity of β-ionone in zebrafish (Danio rerio) embryos from 2 to 120 h post fertilization (hpf) and investigate embryo development, locomotor behavior and pigmentation under different concentrations. The results showed that exposure to β-ionone had an acute toxicity to early life stages of zebrafish and induced a decrease in hatching rate and an increase in the mortality and malformation rate. The median lethal concentration (LC50) of β-ionone at 96 h was observed as 1321 μg/L. In addition, β-ionone not only affected the body length of zebrafish larvae but also regulated the transcription of genes and the levels of hormones involved in the growth hormone/insulin-like growth factor (GH/IGF) and the hypothalamic-pituitary-thyroid (HPT) axes. Moreover, exposure to β-ionone induced significant decreases in locomotor activity and catecholamine neurotransmitters levels. Furthermore, β-ionone stimulated pigmentation via regulation of tyrosinase activity and melanin-related gene expression. Overall, this research could provide new insights into the potential risk of odorants to aquatic organisms.

Abstract
Due to the increase in fungal resistance to existing drugs, a need exists to search for new antifungals. This study aimed to evaluate the antifungal activity of α, β, and δ-damascone and inclusion complexes with β-cyclodextrin against different Candida spp. The inclusion complex of β-damascone was prepared by the co-evaporation method using three molar proportions (1:1; 2:1; 3:1 (βDA-βCD)) and analyzed using Fourier transform infrared spectroscopy (FTIR). Standard Candida albicans (CA INCQS 40,006), Candida krusei (CK INCQS 40,095), and Candida tropicalis (CT INCQS 40,042) strains were used to evaluate antifungal activity. The substances were tested individually or in association with fluconazole (FCZ). The IC50 and cell viability curve constructions were performed using the microdilution method. The minimum fungicidal concentration (MFC) was determined by the subculture method in a solid medium. The α, β, and δ-DA isolated or in combination with fluconazole (FCZ) showed significant antifungal activity. β-damascone showed effective complexation in the three molar proportions assayed; however, none of the inclusion complexes was demonstrated clinically significant effects against the fungal tested. Then, all compounds have shown promising antifungal activities; however, in vivo assays are necessary to have therapeutical application in the future.

Abstract
β-Ionone is a natural plant volatile compound, and it is the 9,10 and 9′,10′ cleavage product of β-carotene by the carotenoid cleavage dioxygenase. β-Ionone is widely distributed in flowers, fruits, and vegetables. β-Ionone and other apocarotenoids comprise flavors, aromas, pigments, growth regulators, and defense compounds; serve as ecological cues; have roles as insect attractants or repellants, and have antibacterial and fungicidal properties. In recent years, β-ionone has also received increased attention from the biomedical community for its potential as an anticancer treatment and for other human health benefits. However, β-ionone is typically produced at relatively low levels in plants. Thus, expressing plant biosynthetic pathway genes in microbial hosts and engineering the metabolic pathway/host to increase metabolite production is an appealing alternative. In the present review, we discuss β-ionone occurrence, the biological activities of β-ionone, emphasizing insect attractant/repellant activities, and the current strategies and achievements used to reconstruct enzyme pathways in microorganisms in an effort to to attain higher amounts of the desired β-ionone.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 268:113676. [PMID: 33301915 DOI: 10.1016/j.jep.2020.113676] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 11/28/2020] [Accepted: 12/04/2020] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Albizia lebbeck and Albizia zygia are used in Nigeria, South Africa and other countries for the treatment of flu, fever, pain, epilepsy, and inflammation. AIM OF THE STUDY Application of plant essence for treating ailments is common among local communities. This research was designed to characterize the volatile compounds and evaluate the toxicity, anti-inflammatory and anti-nociceptive properties of this plant species. MATERIALS AND METHODS The volatile oils were analysed comprehensively utilizing gas chromatography-flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS) using the HP-5 column. The toxicity was evaluated using the toxicity assay. The anti-nociceptive and anti-inflammatory assays were analysed by a hot plate, Formalin, and carrageenan-induced edema assays, respectively. RESULTS The essential oils were obtained in a yield of 0.1% (v/w) calculated on a dry weight basis for both oils. The main compounds of A. lebbeck were 2-pentylfuran (16.4%), (E)-geranyl acetone (15.46%), (E)-α-ionone (15.45%) and 3-Octanone (11.61%), while the oil of A. zygia is mainly hexahydrofarnesyl acetone (33.14%), (E)-methyl isoeugenol (11.7%) and 2-methyl tetradecane (6.64%). The volatile oils are non-toxic to about 5000 mg/kg dose. Albizia zygia significantly (P < 0.001) suppressed the nociceptive afferent fibres in a non-dose dependent manner in comparison to A. lebbeck in the hot plate model. Both oils inhibited nociceptive mediators at both phases of the formalin-induced assay, with a maximum inhibition (100%) at the inflammatory stage. The volatile oils inhibited the Carrageenan-induced inflammation at all phases ranging from P < 0.05 to P < 0.001. The probable pro-inflammatory inhibitory mechanism might be the suppression of some pain biomarkers such as histamine, serotonin, bradykinin, and the Interleukins (ILs) induced by the edema. Volatile constituents such as ionones, eugenol derivatives and other compounds cause the anti-nociceptive and anti-inflammatory activities reported. CONCLUSION This is the first report of the volatile oils and bioassays of Albizia zygia, while the study also confirms previous studies of A. lebbeck. Generally, the findings further prove the use of the plants as pain ameliorating agents.

Abstract
Background Cinnamyl alcohol is not only a kind of flavoring agent and fragrance, but also a versatile chemical applied in the production of various compounds. At present, the preparation of cinnamyl alcohol depends on plant extraction and chemical synthesis, which have several drawbacks, including limited scalability, productivity and environmental impact. It is therefore necessary to develop an efficient, green and sustainable biosynthesis method. Results Herein, we constructed a recombinant Escherichia coli BLCS coexpressing carboxylic acid reductase from Nocardia iowensis and phosphopantetheine transferase from Bacillus subtilis. The strain could convert cinnamic acid into cinnamyl alcohol without overexpressing alcohol dehydrogenase or aldo–keto reductase. Severe product inhibition was found to be the key limiting factor for cinnamyl alcohol biosynthesis. Thus, a biphasic system was proposed to overcome the inhibition of cinnamyl alcohol via in situ product removal. With the use of a dibutyl phthalate/water biphasic system, not only was product inhibition removed, but also the simultaneous separation and concentration of cinnamyl alcohol was achieved. Up to 17.4 mM cinnamic acid in the aqueous phase was totally reduced to cinnamyl alcohol with a yield of 88.2%, and the synthesized cinnamyl alcohol was concentrated to 37.4 mM in the organic phase. This process also demonstrated robust performance when it was integrated with the production of cinnamic acid from l-phenylalanine. Conclusion We developed an efficient one-pot two-step biosynthesis system for cinnamyl alcohol production, which opens up possibilities for the practical biosynthesis of natural cinnamyl alcohol at an industrial scale.![]()

Abstract
Skeletal muscle atrophy is a common and debilitating condition that lacks a pharmacological therapy. Our aim was to investigate the potential of α-ionone, a naturally occurring flavoring agent, in preventing muscle atrophy and to delineate the mechanisms involved. We found that α-ionone not only stimulated myogenesis but also attenuated palmitic-acid-induced atrophy of cultured skeletal myotubes, as evidenced by an increased myotube diameter and length, fusion index, and cellular protein content. These beneficial actions of α-ionone were abrogated by cAMP inhibitor. The antiatrophic effects of α-ionone on cultured myotubes were confirmed in a corresponding mouse model. The skeletal muscle mass, muscle protein content, myofiber diameter, and muscle strength were greater in α-ionone-treated mice than in untreated animals fed high-fat diet. Furthermore, α-ionone increased cAMP concentration and enhanced its downstream PKA-CREB signaling in skeletal muscle of mice fed high-fat diet. Thus, α-ionone is a promising agent that may enhance skeletal muscle mass and strength.

α-Ionone Protects Against UVB-Induced Photoaging in Human Dermal Fibroblasts. Molecules 2019; 24:molecules24091804.

Abstract
Ultraviolet (UV) light-induced wrinkle formation is a major dermatological problem and is associated with alteration in collagen. Here, we investigated the potential of α-ionone, a naturally occurring aromatic compound, in regulation of UVB-induced photoaging in human Hs68 dermal fibroblasts and identified the mechanisms involved. We found that in human dermal fibroblasts, α-ionone inhibited UVB-induced loss of collagen. α-Ionone upregulated the molecules participating in the TGF-β–SMAD pathway (TGF-β1, phospho-SMAD2/3, Col1A1, and Col1A2), but downregulated the molecules involved in the MAPK–AP-1 signaling pathway (phospho-p38, phospho-JNK, phospho-ERK, phospho-c-Fos, phospho-c-Jun, MMP1, MMP3, and MMP9), in human dermal fibroblasts. α-Ionone treatment also increased hyaluronic acid contents, and this effect was accompanied by an upregulation of mRNA expression of genes (HAS1 and HAS2) involved in hyaluronic acid synthesis. Thus, α-ionone is effective in the prevention of UVB-induced decrease of collagen and hyaluronic acid in human dermal fibroblasts. We propose that α-ionone may prove beneficial for the prevention of UV-induced wrinkle formation and skin damage.

Abstract
Red pepper (Capsicum annuum L.) has been used as one of key ingredients in certain fermented foods due to it providing a unique hot and spicy sensation. In this study, volatile compounds-including degradation compounds of carotenoids-in fermented red pepper inoculated with Lactobacillus parabuchneri were investigated. In total, the contents of certain alcohols, benzene and its derivatives, esters, hydrocarbons, lactones, pyrazines, and terpenes were increased in red pepper inoculated with L. parabuchneri, while those of aldehydes, sulfur-containing compounds, and ketones decreased during the fermentation period. The contents of some degradation compounds of carotenoids (β-ionone, β-cyclocitral, α-ionone, and β-damascenone) increased significantly with the fermentation period. In particular, the content of β-damascenone-which could form by the degradation of neoxanthin-increased gradually during fermentation, but this compound was not detected in 0-day samples. These findings indicate that the contents of certain volatiles-including degradation compounds of carotenoids-in fermented red pepper inoculated with L. parabuchneri can change markedly during the fermentation process. PRACTICAL APPLICATION This study investigated the changes of volatiles and carotenoids degradation compounds in fermented red pepper inoculated with Lactobacillus parabuchneri during fermentation. These results could be used to improve the quality of red pepper-based products and in the development of certain fermented foods, including Gochujang (fermented red pepper paste) and kimchi.

Abstract
β-ionone (BIO) is used in fragrances, toiletries and non-cosmetic products, and as a flavor food additive. Notwithstanding the widespread human exposure, there are limited data on the reproductive toxicity of BIO. This study evaluated the developmental toxicity of BIO (0, 125, 250, 500 and 1000 mg/kg body weight/day) given orally to rats on days 6-15 of gestation (GD6-15). C-section was on GD21 and implantations, living and dead fetuses and resorptions were recorded. Fetuses were weighed, and examined for external abnormalities and skeleton and visceral anomalies. The embryotoxicity of a single oral dose of BIO (1000 mg/kg body wt) given on GD11 was evaluated as well. At the highest dose, BIO reduced weight gain and produced chromodacryorrhea and other signs of toxicity. BIO did not increase the frequency of malformations nor did it retard fetal growth. Nonetheless, BIO decreased the pregnancy rate in the group of females exposed on GD6-15, and increased the resorption rate in those treated on GD11 only. In conclusion, except for a higher embryolethality at a maternally toxic dose, BIO caused no embryotoxic effect over the dose range tested and the study NOAEL for maternal and developmental toxicity was 500 mg of BIO/ kg of body weight/day.

Abstract
The odorant receptor 51E2 (OR51E2), which is well-characterized in prostate cancer cells and epidermal pigment cells, was identified for the first time as the most highly expressed OR in human fetal and adult retinal pigment epithelial (RPE) cells. Immunofluorescence staining and Western blot analysis revealed OR51E2 localization throughout the cytosol and in the plasma membrane. Additionally, immunohistochemical staining of diverse layers of the eye showed that the expression of OR51E2 is restricted to the pigment cells of the RPE and choroid. The results of Ca2+-imaging experiments demonstrate that activation of OR51E2 triggers a Ca2+ dependent signal pathway in RPE cells. Downstream signaling of OR51E2 involves the activation of adenylyl cyclase, ERK1/2 and AKT. The activity of these protein kinases likely accounts for the demonstrated increase in the migration and proliferation of RPE cells upon stimulation with the OR51E2 ligand β-ionone. These findings suggest that OR51E2 is involved in the regulation of RPE cell growth. Thus, OR51E2 represents a potential target for the treatment of proliferative disorders.

Abstract
β-Ionone is an end-ring analog of β-carotenoids which widely distributed in fruit and vegetables. Recent studies have demonstrated anti-proliferative, anti-metastatic and apoptosis induction properties of β-ionone in vitro and in vivo. Also, the studies have focused on investigating the β-ionone action on different types of malignant cells and the possible mechanisms of action. Moreover, the quest of new synthetic β-ionone-based compounds possessing anti-proliferative, anti-metastatic and apoptosis induction activities may enable the discovery of compounds which can be used in combination regimes thus overcoming tumor resistance to conventional anticancer agents. These new agents will also be useful for targeting distinct signaling pathways, to activate selectively mechanisms for apoptosis in cancer cells but devoid of undesirable side effects. In this paper, we reviewed the potentialities of β-ionone and related compounds in cancer prevention and chemotherapy.

Abstract
Alpha-iso-methylionone (AIM), a fragrance ingredient, was evaluated for systemic toxicity in rats. Male and female Sprague Dawley rats were administered 0, 5, 30, or 500 mg/kg/d AIM via gavage for 90 days. Statistically significant changes in blood chemistry parameters (reduced aspartate aminotransferase [AST], and increased cholesterol, creatinine, and total protein) were observed in both sexes at 500 mg/kg/d. There were statistically significant increases in liver and kidney weights in both sexes and in spleen weights in males at 500 mg/kg/d. Adaptive hepatocyte enlargement was observed in both sexes at 500 mg/kg/d. Globular accumulations of eosinophilic material were observed in the renal tubular epithelium in males at ≥30 mg/kg/d. Thyroid and bone marrow histopathological changes were observed in males at 500 mg/kg/d. The no-observed-effect level was 5 mg/kg/d for males and 30 mg/kg/d for females. Based on histopathological changes in the kidney in males, the no-observed-adverse-effect level was 30 mg/kg/d.
