Abstract
Cardiovascular diseases (CVDs) persist as the predominant cause of mortality, urging the exploration of innovative pharmaceuticals. Mitochondrial dysfunction stands as a pivotal contributor to CVDs development. Sirtuin 3 (SIRT3), a prominent mitochondrial deacetylase known for its crucial role in protecting mitochondria against damage and dysfunction, has emerged as a promising therapeutic target for CVDs treatment. Utilizing isosteviol, a natural ent-beyerene diterpenoid, 24 derivatives were synthesized and evaluated in vivo using a zebrafish model, establishing a deduced structure-activity relationship. Among these, derivative 5v exhibited significant efficacy in doxorubicin-induced cardiomyopathy in zebrafish and murine models. Subsequent investigations revealed that 5v selectively elevated SIRT3 expression, leading to the upregulation of SOD2 and OPA1 expression, effectively preventing mitochondrial dysfunction, mitigating oxidative stress, and preserving cardiomyocyte viability. As a novel structural class of SIRT3 activators with robust therapeutic effects, 5v emerges as a promising candidate for further drug development.

Ozsvár D, Bózsity N, Zupkó I, Szakonyi Z. Synthesis and Study of the Structure-Activity Relationship of Antiproliferative N-Substituted Isosteviol-Based 1,3-Aminoalcohols. Pharmaceuticals (Basel) 2024; 17:262. [PMID: 38399477 PMCID: PMC10893060 DOI: 10.3390/ph17020262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 02/15/2024] [Accepted: 02/17/2024] [Indexed: 02/25/2024] Open
Abstract
Starting from isosteviol, a series of diterpenoid 1,3-aminoalcohol derivatives were prepared via stereoselective transformations. The acid-catalysed hydrolysis and rearrangement of natural stevioside produced isosteviol, which was transformed into the key intermediate methyl ester. In the next step, an 1,3-aminoalcohol library was prepared by the reductive amination of the intermediate 3-hydroxyaldehyde obtained from isosteviol in a two-step synthesis. To study the effect of the carboxylate ester function at position 4, the free carboxylic acid, benzyl ester and acryloyl ester analogues were prepared as elongated derivatives in comparison with our earlier results in this field. The antiproliferative activity of compounds against human tumour cell lines (A2780, HeLa, MCF-7 and MDA-MB-231) was investigated. In our preliminary study, the 1,3-aminoalcohol function with N-benzyl or (1H-imidazol-1-yl)-propyl substitution and benzyl ester moiety seemed essential for the reliable antiproliferative activity. The results obtained could be a good starting point to further functionalisation towards more efficient antiproliferative diterpenes.

Abstract
Metal-organic frameworks are porous polymeric materials formed by linking metal ions with organic bridging ligands. Metal-organic frameworks are used as sensors, catalysts for organic transformations, biomass conversion, photovoltaics, electrochemical applications, gas storage and separation, and photocatalysis. Nonetheless, many actual metal-organic frameworks present limitations such as toxicity of preparation reagents and components, which make frameworks unusable for food and pharmaceutical applications. Here, we review the structure, synthesis and properties of cyclodextrin-based metal-organic frameworks that could be used in bioapplications. Synthetic methods include vapor diffusion, microwave-assisted, hydro/solvothermal, and ultrasound techniques. The vapor diffusion method can produce cyclodextrin-based metal-organic framework crystals with particle sizes ranging from 200 nm to 400 μm. Applications comprise food packaging, drug delivery, sensors, adsorbents, gas separation, and membranes. Cyclodextrin-based metal-organic frameworks showed loading efficacy of the bioactive compounds ranging from 3.29 to 97.80%.

Abstract
The immune system of active and inactive chronic hepatitis B, as prolonged forms of hepatitis B, is unable to eradicate hepatitis B virus (HBV) from the infected hepatocytes completely. Toll-like receptors (TLRs) play key roles in the viral recognition and promotion of appropriate immune responses. The molecules also participate in the alteration of the target cell functions and transformation. TLR2 is the unique molecule that makes either homodimer or heterodimer with TLR1 and 6 and shows variable roles against viral infections. Therefore, it has been hypothesized that TLR2 may participate in both immune response against HBV and induction of the virus-related hepatic complications. The studies confirm the hypothesis and revealed that TLR2 is not only one of the main molecules altering the course of HBV infection, but also plays key roles in induction of hepatocellular carcinoma (HCC) and liver cirrhosis. However, recent studies demonstrated that the molecule can fight against HCC and liver cirrhosis. Collectively, it appears that nutrition habits, TLR2 gene polymorphisms, gut microbiome, HBV antigens, and activation of other receptors may play key roles in the determination of TLR2 functions.

Abstract
Cyclodextrin metal-organic framework (CD-MOF) as a highly porous supramolecular carrier could be one of the solutions to the insolubility of isosteviol (STV). The solubility of STV was lower than 20.00 ng/mL at pH 1.0 and pH 4.5, whilst its solubility increased to 20,074.30 ng/mL at pH 6.8 and 129.58 ng/mL in water with a significant pH-dependence. The in vitro release profiles of STV from STV@CD-MOF (0.5:1) were pH-independent in distinct pH media and closed to be thoroughly released but no such release profiles were observed for STV@CD-MOF (1:1) owing to nanoclusters formation. The bioavailability of STV@CD-MOF (1:1) in rats was 8.67-fold higher than that of STV, and was 1.32- and 1.27-fold higher than that of STV@CD and STV@CD-MOF (0.5:1). Our results indicated that the inclusion mechanism played a primary role when STV in CD-MOF was at a low loading ratio, while the increasement in bioavailability at a high loading ratio, which was attributed to the nanocluster mechanism. This was confirmed by molecular simulation. In conclusion, CD-MOF is a promising system for STV loading, overcoming the insolubility and to improve the bioavailability of this natural compound.

Abstract
NC-8 (ent-16-oxobeyeran-19-N-methylureido) is an isosteviol-derived analogue with multiple biological effects, including anti-inflammation and anti-bacterial activities and inhibition of HBV viral surface antigen gene expression. In this study, we explored the effects of NC-8 on the formation of osteoclasts from RAW 264.7 cells. We found that NC-8 exerts the novel effect of inhibiting osteoclast-like cell formation. Our experiments showed that RANKL-induced ERK, p38, and JNK phosphorylation were inhibited by NC-8. An ovariectomy-induced osteoporosis animal model was used to examine the protective effects of oral treatment with NC-8. Serum analysis was used to examine markers of osteoblasts, osteoclasts, and renal and hepatic function in rats. Micro CT scanning and histological analysis were used to measure bone loss in ovariectomized rats. Oral administration of NC-8 effectively decreased excess bone resorption and significantly antagonized trabecular bone loss in ovariectomized rats. Serum analysis of C-terminal telopeptide of type-I collagen, an osteoclast marker, also showed that NC-8 administration inhibited excess bone resorption. Furthermore, serum analysis showed that renal and liver function were not affected by these doses of NC-8 during long-term treatment. Our results demonstrate that NC-8 inhibits osteoclast differentiation and effectively ameliorates ovariectomy-induced osteoporosis.

Abstract
Compound 1 (ent-16-oxobeyeran-19-N-methylureido) is a semisynthetic isosteviol derivative that shows anti-hepatitis B virus activity in Huh7 cells by affecting viral DNA transcription and the Toll-like receptor 2/nuclear factor-κB signaling pathway. Thus, the pharmacokinetics and metabolite identification were studied as part of the discovery and development process of compound 1. The pharmacokinetics was evaluated after administration to rats at an intravenous dose of 2 mg/kg, and oral doses of 2, 5 and 10 mg/kg. Plasma concentrations were determined using LC-MS/MS. Moreover, urine samples from rats dosed at 10 mg/kg were scanned for metabolites using UPLC-QTOF-MS/MS. Results for the intravenously administered dose of 2 mg/kg showed that the area under the concentration-time curve was 65,223.31 ± 4269.80 ng min/mL, and the systemic clearance was 0.031 ± 0.0021 L/min. Oral pharmacokinetic parameters were dose-dependent, showing nonproportional increases in the oral AUCs with respective values of 4371.62 ± 3084.81, 22,472.75 ± 9103.33 and 135,141.83 ± 38,934.03 ng min/mL for 2, 5 and 10 mg/kg. The bioavailability was low at 1.5% for 2 mg/kg dose, and at 1.1% for both 5 and 10 mg/kg doses. Metabolites excreted in the urine indicate possible N-oxidation and glucuronide conjugation.

Abstract
ent-16-Oxobeyeran-19-N-methylureido (NC-8) is a recently synthesized derivative of iso-steviol that showed anti-hepatitis B virus (HBV) activity by disturbing replication and gene expression of the HBV and by inhibiting the host toll-like receptor 2/nuclear factor-κB signaling pathway. To study its pharmacokinetics as a part of the drug development process, a highly sensitive, rapid, and reliable liquid chromatography tandem mass spectrometry (LC–MS/MS) method was developed and validated for determining NC-8 in rat plasma. After protein precipitation extraction, the chromatographic separation of the analyte and internal standard (IS; diclofenac sodium) was performed on a reverse-phase Luna C18 column coupled with a Quattro Ultima triple quadruple mass spectrometer in the multiple-reaction monitoring mode using the transitions, m/z 347.31 → 75.09 for NC-8 and m/z 295.89 → 214.06 for the IS. The lower limit of quantitation was 0.5 ng/mL. The linear scope of the standard curve was between 0.5 and 500 ng/mL. Both the precision (coefficient of variation; %) and accuracy (relative error; %) were within acceptable criteria of <15%. Recoveries ranged from 104% to 113.4%, and the matrix effects (absolute) were nonsignificant (CV ≤ 6%). The validated method was successfully applied to investigate the pharmacokinetics of NC-8 in male Sprague–Dawley rats. The present methodology provides an analytical means to better understand the preliminary pharmacokinetics of NC-8 for investigations on further drug development.

Abstract
ent-13-Hydroxykaur-16-ene-19-N-butylureide (6) was one of 33 synthesized C-4-substituted steviol derivatives that were evaluated for their effects on hepatitis B virus (HBV) surface antigen (HBsAg) secretion. The IC50 (16.9 μM) and SI (57.7) values for inhibiting HBV DNA replication of compound 6 were greater than those of the reference compound, lamivudine (3-TC; IC50: 107.5 μM; SI: 22.0). Thus, the anti-HBV mechanism of 6 was investigated, and it specifically inhibited viral gene expression and reduced viral DNA levels, as well as potently attenuated all of the viral promoter activity of HBV-expressing Huh7 cells. Examination of cellular signaling pathways found that 6 inhibited the activities of the nuclear factor (NF)-κB- and activator protein (AP)-1 element-containing promoters, but had no effects on AP-2 or interferon-stimulated response element (ISRE)-containing promoters in HBV-expressing cells. Meanwhile, it significantly eliminated NF-κB and extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) signaling-related protein levels and inhibited their phosphorylation in HBV-transfected Huh7 cells. The inhibitory potency of 6 against HBV DNA replication was reversed by cotransfecting the NF-κB p65 expression plasmid. Using the MAPK-specific activator anisomycin also reversed the inhibitory effect of 6 on viral DNA replication. The present findings suggest that the anti-HBV mechanism of 6 is partly mediated through the NF-κB and MAPK signaling pathways.

Synthesis and anti-hepatitis B virus activity of C4 amide-substituted isosteviol derivatives. Bioorg Med Chem 2015; 23:720-8.

Abstract
A series of novel isosteviol derivatives having C4-amide substituents were synthesized in order to test for antiviral effects against the hepatitis B virus (HBV) in vitro. Among them, IN-4 [N-(propylcarbonyl)-4α-amino-19-nor-ent-16-ketobeyeran] (5) exhibited inhibitory activity against secretion of HBsAg and HBeAg as well as inhibition of HBV DNA replication. Therefore, the mechanism of its antiviral activity was further analyzed using HBV-transfected Huh7 cells. Exposure to IN-4 produced minimal inhibitory effects on viral precore/pregenomic RNA expression. However, expression levels of the 2.4/2.1-kb preS/major S RNA of the viral surface gene significantly decreased, along with intracellular levels of HBV DNA. A promoter activity analysis demonstrated that IN-4 significantly inhibited viral X, S, and preS expression levels but not viral core promoter activities. In particular, IN-4 was observed to significantly inhibit HBV gene regulation by disrupting nuclear factor (NF)-κB-associated promoter activity. In addition, the nuclear expression of p65/p50 NF-κB member proteins was attenuated following IN-4 treatment, while cytoplasmic IκBα protein levels were enhanced. Meanwhile, IN-4 was observed to inhibit the binding activity of NF-κB to putative DNA elements. Furthermore, transfection of a p65 expression plasmid into Huh7 cells significantly reversed the inhibitory effect of IN-4 on HBV DNA levels, providing further evidence of the central role of NF-κB in its antiviral mechanism. It is therefore suggested that IN-4 inhibits HBV by interfering with the NF-κB signaling pathway, resulting in downregulation of viral gene expression and DNA replication.

Anti-viral effect of a compound isolated from Liriope platyphylla against hepatitis B virus in vitro. Virus Res 2014; 192:16-24.

Abstract
The compound LPRP-Et-97543 was isolated from Liriope platyphylla roots and was observed to have potential anti-viral effects in HepG2.2.15 cells against hepatitis B virus (HBV). The antiviral mode was further clarified, and the HBV-transfected Huh7 cells were used as the platform. During viral gene expression, LPRP-Et-97543 treatment had apparent effects on the viral precore/pregenomic and S/preS RNA. Promoter activity analysis demonstrated that LPRP-Et-97543 significantly reduced Core, S, and preS but not X promoter activities. Further examination showed that putative signaling pathways were involved in this inhibitory effect, indicating that NF-κB may serve a putative mediator of HBV gene regulation with LPRP-Et-97543. In addition, the nuclear expression of p65/p50 NF-κB member proteins was attenuated with LPRP-Et-97543 and augmented cytoplasmic IκBα protein levels but without affecting the expression of these proteins in HBV non-transfected cells during treatment. Moreover, LPRP-Et-97543 reduced the binding activity of NF-κB protein to CS1 element of HBV surface gene in a gel retardation analysis and inhibited CS1 containing promoter activity in HBV expressed cells. However, HBV transfection significantly enhances CS1 containing promoter activity without compound treatment in cells. Finally, transfection of the p65 expression plasmid significantly reversed the inhibitory effect of LPRP-Et-97543 on the replicated HBV DNA level in HBV positive cells. In conclusion, this study suggests that the mechanism of HBV inhibition by LPRP-Et-97543 may involve the feedback regulation of viral gene expression and viral DNA replication by HBV viral proteins, which interferes with the NF-κB signaling pathway.
