Abstract
Monoterpenes are secondary metabolites of plants belonging to the terpenoid class of natural products. They are the most abundant components of essential oils that are generally considered to have various pharmacological properties. These compounds are reported to have antidiabetic effects in recent years. Due to nature's complex biosynthetic machinery, they also exhibit a reasonable degree of structural complexity/diversity for further analysis in structure-activity studies. Therefore, monoterpenes as antidiabetic agents have been investigated by recent in vitro and in vivo studies extensively reported in the scientific literature and claimed by patent documents. The purpose of this survey is to provide a comprehensive and prospective review concerning the potential applications of monoterpenes in the treatment of diabetes. The data for this research were collected through the specialized databases PubMed, Scopus, Web of Science, and ScienceDirect between the years 2014 and 2022, as well as the patent databases EPO, WIPO, and USPTO. The research used 76 articles published in the leading journals in the field. The main effect observed was the antidiabetic activity of monoterpenes. This review showed that monoterpenes can be considered promising agents for prevention and/or treatment of diabetes as well as have a marked pharmaceutical potential for the development of bioproducts for therapeutics applications.

Anti-atherosclerotic Effects of Myrtenal in High-Fat Diet-Induced Atherosclerosis in Rats. Appl Biochem Biotechnol 2022; 194:5717-5733. [PMID: 35804285 DOI: 10.1007/s12010-022-04044-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/26/2022] [Indexed: 11/02/2022]
Abstract
The major cause of death worldwide is atherosclerosis-related cardiovascular disease (ACD). Myrtenal was studied to determine control rats were given standard diets and a high-fat diet was given to AS model groups. Atherosclerosis-related cardiovascular disease (ACD) is globally attributed to being a predominant cause of mortality. While the beneficial effects of Myrtenal, the monoterpene from natural compounds, are increasingly being acknowledged, its anti-atherosclerotic activity has not been demonstrated clearly. The present study is proposed to determine the anti-atherosclerotic activity of Myrtenal in high-fat diet-induced atherosclerosis (AS) rat models. Control groups were maintained with standard diets, the AS model rats were provided a high-fat diet, two of the experimental groups fed with a high-fat diet were treated with Myrtenal (50 mg/kg and 100 mg/kg), and one experimental group on high-fat diet was treated with simvastatin (10 mg/kg) for 30 days. The levels of inflammatory cytokines were analyzed using kits. The lipoproteins and the lipid profile were estimated using an auto-analyzer. The atherogenic index and marker enzyme activities were also determined. Serum concentrations of 6-keto-prostaglandin F1α (6-keto-PGF1α), thromboxaneB2 (TXB2), endothelin (ET), and nitric oxide (NO) were measured. The AS model groups indicated altered lipid profile, lipoprotein content, atherogenic index, calcium levels, HMG-CoA reductase activity, collagen level, and mild mineralization indicating atherosclerosis, while the AS-induced Myrtenal-treated groups demonstrated anti-atherogenic activity. The Myrtenal-treated groups exhibited a decreased TC, TG, and LDLc levels; increased HDLc levels; and a decline in the inflammatory cytokines such as CRP, IL-1β, IL-8, and IL-18 when compared to the untreated AS rats. Furthermore, Myrtenal decreased ET, TXB2, and 6-keto-PGF1α levels indicating its anti-atherosclerotic activity. The study results thus indicate that Myrtenal modulates the lipid metabolic pathway to exert its anti-atherosclerotic activity.

OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:1499510. [PMID: 35345832 PMCID: PMC8957427 DOI: 10.1155/2022/1499510] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 01/09/2022] [Accepted: 01/19/2022] [Indexed: 12/23/2022]
Abstract
The present research intended to assess the possible protective and hypoglycemic effect of Actinidia deliciosa fruit aqueous extract (ADAE) in diabetic rats. The scavenging antioxidant capabilities of ADAE were evaluated using GC-MS analysis. In addition, rats were divided into four groups: control, ADAE, streptozotocin-induced DM (STZ), and STZ-treated rats + ADAE in an in vivo investigation. GC-MS analysis of ADAE was shown to include major components with high total phenolic contents and high DPPH scavenging activity. In diabetic rats, significant elevation in blood glucose level, lipid peroxidation, bilirubin, and lactate dehydrogenase activity as well as a change in lipid profile was observed, while insulin, body and liver weights, enzymatic and nonenzymatic antioxidants, liver function biomarkers, and protein content were significantly decreased. Furthermore, changes in the expression of the peroxisome proliferator-activated receptor (PPAR-γ), apoptotic, and inflammation-related genes were found. In addition, histological differences in rat liver tissue architecture were discovered, corroborating the biochemical modifications. However, consuming ADAE alone reduced lipid peroxidation and improved antioxidant status. Furthermore, diabetic rats given ADAE showed significant reductions in oxidative stress indicators and biochemical parameters, as well as improved tissue structure, when compared to the diabetic rats' group. Also, ADAE supplementation protects diabetic rats' hepatic tissue by upregulating PPAR-γ and downregulating apoptotic and inflammatory-related gene expression. In conclusion, A. deliciosa has beneficial protective effects so, it might be used as a complementary therapy in diabetes mellitus.

In Vitro and In Vivo Antidiabetic Potential of Monoterpenoids: An Update. MOLECULES (BASEL, SWITZERLAND) 2021; 27:molecules27010182.

Abstract
Diabetes mellitus (DM) is a chronic metabolic condition characterized by persistent hyperglycemia due to insufficient insulin levels or insulin resistance. Despite the availability of several oral and injectable hypoglycemic agents, their use is associated with a wide range of side effects. Monoterpenes are compounds extracted from different plants including herbs, vegetables, and fruits and they contribute to their aroma and flavor. Based on their chemical structure, monoterpenes are classified into acyclic, monocyclic, and bicyclic monoterpenes. They have been found to exhibit numerous biological and medicinal effects such as antipruritic, antioxidant, anti-inflammatory, and analgesic activities. Therefore, monoterpenes emerged as promising molecules that can be used therapeutically to treat a vast range of diseases. Additionally, monoterpenes were found to modulate enzymes and proteins that contribute to insulin resistance and other pathological events caused by DM. In this review, we highlight the different mechanisms by which monoterpenes can be used in the pharmacological intervention of DM via the alteration of certain enzymes, proteins, and pathways involved in the pathophysiology of DM. Based on the fact that monoterpenes have multiple mechanisms of action on different targets in in vitro and in vivo studies, they can be considered as lead compounds for developing effective hypoglycemic agents. Incorporating these compounds in clinical trials is needed to investigate their actions in diabetic patients in order to confirm their ability in controlling hyperglycemia.

Abstract
Mono- and sesquiterpenoids are the main chemical constituents of essential oils. Essential oils and their constituents have received increasing attention for lipid-lowering properties in both cell and animal models. Despite the chemical diversity of essential oil compounds, the effects of many of these compounds on cholesterol metabolism are highly similar. In this report, we review the literature regarding the effects of essential oils and their terpenoid constituents on cholesterol homeostasis, and explore likely mechanisms using protein-ligand docking. We identified 98 experimental and seven clinical studies on essential oils, isolated compounds, and blends; 100 of these described improvements either in blood cholesterol levels or in sterol metabolic pathways. Our review and docking analysis confirmed two likely mechanisms common to many essential oil compounds: (1) direct agonism of peroxisome-proliferator-activated receptors, and (2) direct interaction with sterol-sensing domains, motifs found in key sterol regulatory proteins including sterol regulatory element binding protein cleavage activating protein and HMG-CoA reductase. Notably, these direct interactions lead to decreased transcription and accelerated degradation of HMG-CoA reductase. Our work suggests that terpene derivatives in essential oils have cholesterol-lowering activity and could potentially work synergistically with statins, however, further high quality studies are needed to establish their clinical efficacy.

Abstract
The present study was undertaken to evaluate the chemopreventive activity of myrtenal, a natural monoterpene, against bladder carcinoma in rats induced with N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN) and promoted with γ-ionizing radiation (γ-IRR) as well as to assess the involvement of inflammation, apoptosis and oxidative damage in tumor development. Histopathological examination of rat bladder revealed the presence of noninvasive papillary transitional cell carcinoma (Grade 2) in sections from BBN group indicating the credibility of the applied carcinogenesis model. Myrtenal treatment caused improvement in urinary bladder mucosa with cells more likely in Grade 1. Administration of myrtenal to BBN-treated rats exhibited downregulation in the expressions of COX-2, NF-kB and STAT-3 associated with suppression of inflammatory cytokines levels of TNF-α and IL-6 as well as biomarkers of oxidative damage (MDA & NO). In addition, myrtenal treatment caused a significant increase in caspase-3 activity and Bax/Bcl-2 ratio. Data obtained suggested that the anti-inflammatory effect and the induction of apoptosis contributed largely to the beneficial antitumor effects of myrtenal in rats with BBN/γ-IRR-induced bladder carcinoma. Present findings, in addition to benefits described in other pathologies, indicated myrtenal as a potential adjuvant natural compound for the prevention of tumor progression of bladder cancer.

Abstract
Atherosclerosis (AS) is a cardiovascular disease that arise due to dysfunction of lipid deposition and metabolism. AS is causes the mortality and morbidity worldwide. Sinomenine isolated from the Sinomenium acutum is used extensively against the various cardiac diseases in China. However, the anti-atherosclerosis effect of sinomenine still not explore. In this study, we explore the cardioprotective and anti-atherosclerosis effect of sinomenine against Vitamin D3 and High fat induced atherosclerosis in rats. Sprague Dawley (SD) rats were used in this study. The rats were received the vitamin D (60000) and High fat diet to induce the atherosclerosis and divided into groups and received the oral administration of sinomenine (2.5, 5 and 10 mg/kg) and simvastatin (5 mg/kg). Body weight, organ weight and biochemical parameters were estimated. The mRNA expression of MyD88, TLR4, NF-κB and IκB were estimated. Sinomenine treated rats significantly (p<0.001) suppressed the body weight and modulated the organ weight (hepatic, renal and heart). Sinomenine significantly (p<0.001) decreased the level of triacylglycerols (TG), low density lipoprotein cholesterol (LDL-c), total cholesterol (TC), very low-density lipoprotein cholesterol (VLDL-c) and augmented the level of high-density lipoprotein cholesterol (HDL-c). Sinomenine treatment also reduced the level of atherogenic index (TC/HDL-c and LDL-c/HDL-c). Sinomenine treatment decrease the ratio of HMG CoA/Mevalonate and level of collagen and total protein. Sinomenine significantly (p<0.001) altered the level of heart parameters, antioxidant parameters and inflammatory cytokines. Sinomenine significantly (p<0.001) reduced the expression of MyD88, TLR4, NF-κB and IκB. Taken together, sinomenine exhibited the protective effect against the atherosclerosis via alteration of TLR4/NF-κB signaling pathway.

Abstract
Myrtenal is a natural monoterpene isolated from essential oils of several plants and their derivates have shown to have several biological properties including cytotoxicity. The cytotoxic activity of these derivates are being investigated for their antitumor effect leading to the development of potential anticancer agents. In this study, novels Myrtenyl grafted pseudo-peptides were designed, synthesized and functionally characterized as possible therapeutic agents for cancer treatment. Thirteen novel Myrtenyl grafted pseudo-peptides were prepared in high atom economy and efficiency by a classic Ugi-4CR and sequential post-modification. Their structures were confirmed by NMR, and ESI-MS, and its cytotoxic activity was evaluated in three cancer cell lines and primary CD4+ T cells at different proliferative cycles. Our results revealed that some of these compounds showed significant cytotoxicity against human gastric, breast and colon adenocarcinoma cells lines, but not against human dermal fibroblast cell line. Moreover, from the thirteen novel myrtenyl synthesized the compound (1R,5S)-N-{[1-(3-chlorophenyl)-1H-1,2,3-triazol-4-yl]methyl}-N-[2-(cyclohexylamino)-2–oxoethyl]-6,6-dimethylbicyclo[3.1.1]hept-2-ene-2-carboxamide (3b) proved to be the best candidate in terms of acceptable EC50, and Emax values in cancer cell lines and at inducing cytotoxicity in CD4+ T cells undergoing active proliferation, without affecting non-proliferating T cells. Overall, the synthesis and characterization of our Myrtenyl derivates revealed novel potential anticancer candidates with selective cytotoxic activity.

Abstract
Background Type 1 diabetes mellitus (T1DM) is characterized by insulin-deficient production leading to hyperglycemia, which is associated with diabetic complications such as cardiovascular diseases. Antioxidants have been proving a good alternative to diabetic complications, with N-acetylcysteine (NAC) having antioxidant characteristics. The aim of this study was to assess the effect of NAC on the lipid profile and the atherogenic index (AI) in streptozotocin- (STZ-) induced diabetic rats. Method 32 male Wistar rats (60 days of age) weighting ±250 g were randomly distributed into four groups (n = 8): CTRL: control rats; CTRL+NAC: control rats treated with NAC; DM: diabetic rats; DM+NAC: diabetic rats treated with NAC. T1DM was induced using STZ (60 mg/kg, ip; single dose), and NAC (25 mg/kg/day) was administrated by gavage, for 37 days. The animals received chow and water ad libitum. After the experimental period, blood and cardiac tissue samples were collected to analyze energetic metabolism, lipid profile, and AI. Results NAC decreased (p < 0.01) glycemia, energy intake, carbohydrate, and protein consumption in diabetic rats (DM+NAC), when compared with DM, while the alimentary efficiency was improved (p < 0.01) in treated diabetic rats (DM+NAC). Diabetic rats treated with NAC decreased (p < 0.01) lipid profile and AI in diabetic rats (DM+NAC) when compared to DM. Conclusion NAC improves lipid profile and decreases AI in STZ-induced diabetic rats.

Abstract
Monoterpenes belong to the terpenoids class of natural products and are bio-synthesized through the mevalonic acid pathway. Their small molecular weight coupled with high non-polar nature make them the most abundant components of essential oils which are often considered to have some general antioxidant and antimicrobial effects at fairly high concentrations. These compounds are however reported to have antidiabetic effects in recent years. Thanks to the ingenious biosynthetic machinery of nature, they also display a fair degree of structural complexity/diversity for further consideration in structure-activity studies. In the present communication, the merit of monoterpenes as antidiabetic agents is scrutinized by assessing recent in vitro and in vivo studies reported in the scientific literature. Both the aglycones and glycosides of these compounds of rather small structural size appear to display antidiabetic along with antiobesity and lipid lowering effects. The diversity of these effects vis-à-vis their structures and mechanisms of actions are discussed. Some key pharmacological targets include the insulin signaling pathways and/or the associated PI3K-AKT (protein kinase B), peroxisome proliferator activated receptor-γ (PPARγ), glucose transporter-4 (GLUT4) and adenosine monophosphate-activated protein kinase (AMPK) pathways; proinflammatory cytokines and the NF-κB pathway; glycogenolysis and gluconeogenesis in the liver; glucagon-like-1 receptor (GLP-1R); among others.
