Abstract
Description
Technical Field
[0001] This invention relates to the application of a novel phytosterol in the field of biomedical technology, and particularly to the use of (24S)-3β-hydroxy-5α-stigmastan-6-one (PN06) in the treatment of benign prostatic hyperplasia, inflammation and tissue fibrosis. Prior Technology
[0002] Benign prostatic hyperplasia (BPH) is the most common benign tumor in older men, with an age-related incidence that accompanies the aging process. BPH is the most common cause of lower urinary tract symptoms (LUTS) in older men, such as increased urinary frequency and slow urine flow. For a long time, the most effective treatment was considered to be endoscopic prostatectomy via the urethra. However, this surgery also has known drawbacks, including bleeding and physiological stress, which can affect recovery in some patients. Furthermore, this surgery requires a high level of technical skill and typically necessitates a three- to five-day hospital stay. These factors have prompted the development of alternative therapies, including medication, minimally invasive surgical techniques, and other forms of endoscopic prostatectomy, aiming to achieve the same therapeutic effects as traditional surgery while reducing patient suffering and costs.
[0003] Furthermore, previously published literature indicates that acute and chronic inflammation is highly associated with LUTS and prostate hypertrophy, and is considered one of the causes of prostate fibrosis leading to bladder outlet obstruction. Inflammation can drive nociceptive signals as well as potential mechanisms for proliferative growth and tissue fibrosis.
[0004] Fibrosis is a pathological feature of most chronic inflammatory diseases. Fibrosis, also known as scarring, occurs when excessive extracellular matrix accumulates due to severe or repeated tissue damage. When fibrosis progresses significantly, it can eventually lead to organ dysfunction and even death. Fibrosis can affect almost every tissue in the body, including pulmonary fibrosis, cirrhosis, cardiac fibrosis, prostate fibrosis, and renal fibrosis. Although fibrosis is considered a major cause of high morbidity and mortality in most chronic inflammatory diseases, specific treatment strategies targeting the pathogenesis of fibrosis are currently extremely rare, if not nonexistent.
[0005] Lotus (Nelumbo nucifera Gaertn.), also known as water lily, belongs to the genus Nelumbo in the family Nelumbonaceae. It is a perennial aquatic plant widely distributed throughout Asia. Its green seed embryo, the lotus heart or lotus seed (Plumula nelumbinis, PN), has long been officially listed in several Chinese Pharmacopoes as a medicinal and food resource. On one hand, the lotus heart exhibits various pharmacological and clinical effects, such as antiarrhythmic, antihypertensive, anti-ischemic, diuretic, antipyretic, antiasthmatic, anti-restenosis, anti-neuropathic, antipsychotic, antidiabetic, anti-autoimmune, antiarrhythmic, anti-Alzheimer's, anticancer, hepatoprotective, anti-inflammatory, and anti-aging activities. However, since the presence of key compounds in PN with potential for treating benign prostatic hyperplasia and inhibiting tissue fibrosis has not yet been identified, the activities associated with these compounds remain to be verified.
[0006] In view of this, there is an urgent need in the field to identify active substances from PN that have the properties to treat benign prostatic hyperplasia, inflammation and tissue fibrosis. These active substances can serve as candidate compounds to develop treatments for diseases related to benign prostatic hyperplasia, inflammation and tissue fibrosis. Summary of the Invention

[0062] [2.] [Quantitative instantaneous reverse transcription polymerase reaction] [(Quantitative real-time RT-PCR)]
[0063] Total ribonucleic acid (RNA) was isolated using the RNeasy mini kit (Qiagen), followed by quantitative real-time reverse transcription polymerase reaction (qRT-PCR) to detect the expression of GAS6, AXL, IL-1, IL-6, TNF-α, and TGF-β. The TaqMan gene expression analysis reagent (Thermo Fisher Scientific) was used; GAPDH was used as an internal control gene.
[0064] [3.] [Enzyme-linked immunosorbent assay] [(Enzyme-Linked Immunosorbent Assay, ELISA)]
[0065] The concentrations of interleukin-1β (IL-1β), interleukin-6 (IL-6), transforming growth factor-β (TGF-β), and tumor necrosis factor-α (TNF-α) in the culture medium were determined using an ELISA kit (Nanjing Jiancheng, Nanjing, China) according to the manufacturer's instructions.
[0066] [4.] [Massen's trichrome staining method] [(Masson's Trichrome Staining)]
[0067] First, 5-micron-thick paraffin-embedded tissue sections (FFPE) were dewaxed and hydrated with distilled water. Next, using Bouin's fixative as a mordant, the sections were treated at 56°C for 1 hour. After cooling, the sections were washed with tap water until the yellow color disappeared. The samples were then stained with Weigert's hematoxylin stain for 10 minutes, followed by thorough washing with tap water for 10 minutes, then stained with acid fuchsin solution for 15 minutes, and then washed with distilled water for 3 minutes. After washing, the slides were treated with phosphomolybdic acid solution for 10 minutes, followed by washing with distilled water for 10 minutes. Finally, they were stained with a light green solution for 2 minutes and washed with distilled water. After dehydration with alcohol, the slides were mounted with coverslips.
[0068] [5.] [Mouse]
[0069] Male BALB / c mice aged 6 to 8 weeks (purchased from the National Laboratory Animal Center, Taipei, Taiwan) were housed in a pathogen-free environment with a 12-hour light / 12-hour dark light cycle and fed autoclaved standard feed and drinking water. Mice were bred at the Animal Center of Chang Gung Memorial Hospital International Medical Center in accordance with the National Institutes of Health (NIH) Regulations Governing the Establishment and Management of Laboratory Animal Care and Use Committees or Subcommittees. All research related to animal experiments was reviewed and approved by the Institutional Animal Care and Use Committee (IACUC) of Chang Gung Memorial Hospital International Medical Center.
[0070] [6.] Carbon tetrachloride [(CCL4)] [Induced mouse model of liver fibrosis]
[0071] The CCL4-induced liver fibrosis experiment in mice was conducted according to the experimental procedure of the mouse liver fibrosis model established in previously published literature (Fan, Xiaobao et al. “Attenuation of CCl4-induced hepatic fibrosis in mice by vaccinating against TGF-β1.”). Mice were intraperitoneally injected twice weekly with 2 µl / g CCL4 until death to induce liver fibrosis. The PN06 treatment group received intraperitoneal injections of 40 mg / kg PN06 three times weekly until death. Mice reached the experimental endpoint at 6 weeks of age and were sacrificed. Liver tissue was collected to observe liver fibrosis and inflammation. The control group received DMSO until death. Mouse body weight was measured weekly throughout the experiment, and weight changes were recorded.
[0072] [7.] [Immunohistochemistry]
[0073] Immunohistochemically stained slides were first incubated at 65°C for 30 minutes, then dewaxed with xylene and rehydrated with graded alcohols. They were then boiled in a microwave oven with Trilogy reagent (Cell Marque, Rocklin, CA) for 10 minutes to retrieval antigens. After washing, the slides were washed with 1x phosphate-buffered saline (PBS) and then immersed in 3% hydrogen peroxide solution for 10 minutes to inhibit endogenous peroxidase activity. After three washes with 1x PBS, the slides were incubated with primary antibody (Santa Cruz Biotechnology Inc., Santa Cruz, CA) at room temperature for 1 hour. After three more washes with 1x PBS, biotin-labeled secondary antibody (Dako, Glostrup, Denmark) was added and incubated for 25 minutes. After three more washes with 1x PBS, horseradish peroxidase-labeled streptavidin was added and incubated at room temperature for 25 minutes. Peroxidase activity was detected at room temperature using DAB substrate chromogen (Dako), and the slides were then counterstained with hematoxylin.
[0074] [8. THP-1] [Cell stimulation and cytokine analysis]
[0075] THP-1 mononuclear spheres (1 × 10⁶ cells per well) were seeded in 6-well culture dishes and induced to differentiate by treatment with 100 nM phorbol 12-myristate 13-acetate (PMA) for 24 hours. After differentiation, cells were pretreated with PN06 or β-sitosterol for 2 hours, followed by stimulation with lipopolysaccharide (LPS; final concentration 100 ng / mL) for 24 hours. The cell culture supernatant was collected by centrifugation (1,000 rpm, 4 °C, 5 min) for subsequent analysis. The concentrations of pro-inflammatory cytokines were quantified using an ELISA kit (BioLegend) according to the manufacturer's instructions.
[0076] [Example] [1] [Continuous updates] [PN06] [It can alleviate age-related prostate hypertrophy and maintain the integrity of abdominal organs in aged mice.]
[0077] In this embodiment, the effects of PN06 on the reproductive system of aged mice were assessed by measuring changes in the morphology and tissue weight of the testes and prostate in young mice (Y; 50 weeks), naturally aged mice (O; 130 weeks), and aged mice long-term supplemented with PN06 (O / PN06; 130 weeks). Aged mice long-term supplemented with PN06 (O / PN06; 130 weeks) were given the drug starting at 50 weeks of age by mixing PN06 into their diet and allowed free access to food. The prostate volume of aged mice (O) was significantly increased, exhibiting typical age-related prostate hypertrophy, while long-term PN06 treatment (O / PN06) effectively reduced prostate volume, with a morphology similar to that of the young group (Y) (Figure 1, (A)). Furthermore, prostate weight analysis showed a significant increase in prostate weight in the aged group (O), while long-term PN06 supplementation (O / PN06) significantly reduced prostate weight, indicating that PN06 can effectively inhibit age-related prostate hypertrophy (Figure 1, (B)). Observation of the abdominal visceral structure of mice showed that the aged group (O) had prostate hypertrophy and abnormal visceral tissue arrangement, while the PN06 group (O / PN06) exhibited a more compact and healthy visceral arrangement compared to the aged group (O), similar to that of young mice (Y) (Figure 1, (C)). In conclusion, PN06 can significantly inhibit age-related prostate hypertrophy and prevent the continued deterioration of the abdominal cavity in aged mice.
[0078] [Example] [2] [:] [PN06] [Compare] [β-] [Sitosterol inhibits more effectively] [THP-1] [In monocytes] [LPS] [Induced inflammatory response]
[0079] In this embodiment, to evaluate the anti-inflammatory potential of PN06 compared to the phytosterol β-sitosterol, THP-1 mononuclear globules were exposed to 200 ng / mL LPS, with or without a specified concentration of PN06 or β-sitosterol, and the concentration of the pro-inflammatory cytokine IL-6 was measured by ELISA. The results are shown in Figure 2.
[0080] As shown in the figure, compared with LPS-induced IL-6 secretion without PN06 or β-sitosterol, PN06 significantly inhibited LPS-induced IL-6 secretion in a dose-dependent manner, with 40 μM PN06 showing a significantly better inhibitory effect than 20 μM. Conversely, neither 20 μM nor 40 μM β-sitosterol could reduce IL-6 levels, and their effects were not significantly different from those of LPS alone. These results indicate that PN06 has superior anti-inflammatory activity compared to β-sitosterol and can effectively reduce the amount of IL-6 (Figure 2).
[0081] [Example] [3] [:] [PN06] [Can reduce inflammation]
[0082] [3.1] [Cytotoxicity] [ ]
[0083] In this embodiment, the human mononuclear cell line THP1 was used to evaluate the cytotoxicity of PN06 in normal cells. The survival rate of the aforementioned human normal cells was determined using MTT assay after 24 hours of treatment with increased PN06 concentration. The results showed that PN06 had no significant effect on cell survival rate below 40 μM; however, cell survival rate decreased slightly when the concentration exceeded 60 μM. Based on this, the present invention selected 10-40 μM as the applicable concentration range for subsequent experiments to ensure that it did not affect the survival rate of THP1 cells (Figure 3, (A)).
[0084] To determine the anti-inflammatory activity of PN06, this invention used the human mononuclear cell line THP1, pretreated with different concentrations of PN06 or empty vector (DMSO) for 2 hours, followed by the addition of 1 μg / mL LPS to induce an inflammatory response. After 24 hours of culture, the culture medium was collected, and cytokine concentrations were measured using ELISA. The results showed that PN06 significantly inhibited the secretion of pro-inflammatory cytokines IL-1β, IL-6, TNF-α, and TGF-β in THP1 cells, further confirming its anti-inflammatory activity (Figure 3, (B)-(E)). In summary, PN06 at concentrations below 40 μM is non-cytotoxic to normal human THP1 cells and exhibits anti-inflammatory activity.
[0085] [3.2 LPS] [Induced inflammatory response] [ ]
[0086] In this embodiment, LPS was used to induce an inflammatory response in mouse macrophage cell line (RAW 264.7 cells), followed by PN06 treatment, and the ability of PN06 to inhibit inflammatory factors was observed. The results are shown in Figure 4.
[0087] Compared to the empty vector (DMSO) treatment group, the concentrations of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α were significantly decreased in the PN06 treatment group, and the concentrations of pro-inflammatory cytokines decreased with increasing PN06 concentration (Figure 4, (A)-(C)). Furthermore, immunospot analysis revealed that, under LPS-induced inflammatory conditions, the expression levels of key regulators of liver inflammation and fibrosis, iNOS and COX2 proteins, were significantly reduced in the PN06 treatment group compared to the empty vector (DMSO) treatment group, and these protein expression levels decreased with increasing PN06 concentration (Figure 4, DE). These results indicate that PN06 significantly inhibits the expression of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α in a dose-dependent manner, and may regulate their anti-inflammatory response by inhibiting the expression of iNOS and COX2.
[0088] [3.3 LPS] [Induced] [MAPK] [Signaling pathways and downstream pro-inflammatory cytokine genes] [ ]
[0089] In this embodiment, the effects of PN06 on LPS-induced MAPK signaling pathways and the expression of downstream pro-inflammatory cytokine genes were investigated. Accordingly, THP1 cells were treated with PN06 and LPS, and cell samples were collected at different time points. Immunomodulation and real-time quantitative PCR were performed to assess the activation status of the MAPK signaling pathways (ERK, JNK, and p38) and the mRNA expression of downstream pro-inflammatory cytokine genes IL-1β, IL-6, TNF-α, and TGF-β. The results are shown in Figure 5.
[0090] Immunomodulation analysis showed that, compared to the untreated group, the PN06-treated group exhibited significantly reduced levels of phosphorylated ERK, JNK, and p-p38, as well as a significant decrease in t-ERK, t-JNK, and t-p38 (Figure 5, (A)). Further analysis using real-time quantitative PCR revealed that, compared to the empty vector (DMSO)-treated group, the PN06-treated group showed a significant decrease in the mRNA expression of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α (Figure 5, BE).
[0091] In summary, PN06 can significantly inhibit LPS-induced MAPK phosphorylation and reduce the expression of downstream pro-inflammatory cytokine genes, further confirming that PN06 has anti-inflammatory activity.
[0092] [Example] [4] [:] [PN06] [Reduce carbon tetrachloride] [(CCL4)] [Induced symptoms of liver fibrosis]
[0093] In this embodiment, the efficacy of compound PN06 on liver fibrosis was investigated. Following the steps described in the Materials and Methods section, experimental animals were induced to develop liver fibrosis with CCL4 (2 µl / g CCL4 injected intraperitoneally twice weekly), and then treated with PN06.
[0094] The results showed no significant difference in body weight between the PN06 treatment group and the DMSO-treated and CCL4-treated liver fibrosis groups (Figure 6, (B)). When the mice reached the experimental endpoint at 6 weeks of age, they were sacrificed, and their liver tissue was collected to observe liver fibrosis and inflammation. The appearance of the mouse liver tissue showed that, compared to the DMSO-treated group, the liver treated with CCL4 exhibited significant fibrosis; however, after PN06 treatment, liver fibrosis was significantly reduced (Figure 6, (C)-(D)). Further sectioning and staining of the liver tissue with Massen's trichrome staining revealed that, compared to the DMSO-treated group, the liver tissue sections treated with CCL4 showed significant inflammation and fibrosis; however, after PN06 treatment, the morphology was similar to that of the DMSO-treated group (Figure 6, (E)).
[0095] Regarding liver function indicators AST and ALT, the results showed that, compared with the DMSO control group, CCL4 induction led to a 1.72-fold and 2.12-fold increase in serum AST and ALT levels in mice, respectively. However, after PN06 treatment, AST decreased to 66% and ALT decreased to 53%, indicating that PN06 can effectively improve liver function (Figure 6, (F)).
[0096] In conclusion, PN06 can significantly reduce pathological changes such as inflammation and fibrosis in liver tissue, has the potential to inhibit the process of liver fibrosis, and effectively improve liver function.
[0097] [Example] [5] [:] [PN06] [Anti-inflammatory mechanism]
[0098] [5.1] [Whole Transcriptosome Sequencing Analysis] [(whole-transcriptome sequencing) ]
[0099] In this embodiment, whole transcriptomic sequencing analysis was used to investigate the effect of PN06 on gene expression. The results showed that in the PN06 group, the expression of 162 genes changed more than 2-fold compared with the control group (DMSO treatment) (Figure 7, (A)). Further bioinformatics analysis showed that these differentially expressed genes are mainly involved in key pathways such as the structure and remodeling of the extracellular matrix (ECM) and cytokine activation, indicating that PN06 can regulate the expression of pro-inflammatory cytokines and ECM formation, consistent with the in vitro and in vivo experimental results of other embodiments disclosed herein (Figure 7, (B)).
[0100] Furthermore, the expression levels of AXL receptor tyrosine kinase and its ligand GAS6 in the PN06 treatment group were reduced by 42% and 37%, respectively, compared to the control group (DMSO). Since the AXL-GAS6 axis is known to be closely related to the activation of human hepatic stellate cells (HSCs), these results suggest that PN06 may participate in the anti-fibrotic mechanism by regulating AXL-GAS6 signaling. To verify the results of the whole transcriptome analysis, HSCs induced by THLE-3 and TGF-β were further treated with PN06 or DMSO for 24 hours, and real-time quantitative PCR analysis was performed. The results showed that PN06 significantly reduced the expression of AXL and GAS6, further supporting its potential regulatory mechanism in anti-hepatic fibrosis (Figure 7C). In summary, PN06 has the ability to regulate inflammation-related genes and the AXL-GAS6 signaling axis, suggesting that it may exert its potential anti-hepatic fibrosis therapeutic effect by inhibiting inflammation- and fibrosis-related pathways.
[0101] [5.2] [Human hepatic stellate cells] [(HSC)] [System activation and extracellular matrix] [(ECM)] [Express]
[0102] Example 5.1 above has demonstrated that GAS6 / AXL signaling is closely related to HSC cell activation. Therefore, PN06 may inhibit HSC activation by reducing the expression of AXL and its ligand GAS6, thereby slowing down liver fibrosis. To verify this hypothesis, this example analyzed the protein expression levels of α-smooth muscle actin (α-SMA) and type I procollagen α1 (COL1A1), both of which are key markers of HSC activation. After 24 hours of PN06 treatment, the immunoblotting results of the HSC cell line showed that the expression levels of α-SMA and COL1A1 were significantly lower than those in the control group, indicating that PN06 can effectively inhibit HSC activation (Figure 8, (A)(B)). In addition, we found that PN06 treatment also significantly inhibited the activation of PI3K / AKT signaling, which is known to regulate the expression of α-SMA and COL1A1 (Figure 8, A and C).
[0103] Overall, these results show that PN06 inhibits the downstream PI3K / AKT signaling pathway by downregulating the expression of GAS6 and AXL, thereby suppressing the activation of HSCs and the expression of ECM-related genes, demonstrating its potential anti-fibrotic effect.
[0104] [5.3] [Human liver stellate cells] [(HHSteC)] [Cell cycle and apoptosis]
[0105] To further evaluate the effects of PN06 on the physiological function of HSCs, this study treated HHSteCs with different concentrations of PN06 for 24 hours, then collected the cells and performed flow cytometry analysis to assess cell cycle distribution and apoptosis rate.
[0106] The results showed that, compared with the control group, the cells in the 40 μM PN06 treatment group were mainly arrested in the S phase, and the number of cells in the sub-G1 phase was significantly increased, indicating that PN06 can inhibit the cell cycle process and induce apoptosis (Figure 9, (A)).
[0107] Furthermore, apoptosis analysis confirmed that the number of apoptotic cells in PN06 was significantly increased compared to the control group, supporting the fact that PN06 can promote HSC apoptosis (Figure 9, (B)). In summary, PN06 can effectively inhibit the survival and activation of human liver stellate cells (HHSteC) by arresting the cell cycle and inducing apoptosis, revealing its potential in the treatment of liver fibrosis.
[0108] [5.4 HSC] [activation and] [ECM] [form]
[0109] To verify whether PN06 inhibits HSC activation and delays liver fibrosis by suppressing GAS6 / AXL signaling, this study used immunohistochemical (IHC) staining to analyze the expression of marker proteins for HSC activation in the liver tissue of CCL4-treated mice. The results showed that, compared to the DMSO control group, the expression levels of α-SMA and COL1A1 in the liver tissue of mice treated with CCL4 were significantly increased. However, in the PN06 group, the expression levels of these proteins were significantly decreased (Figure 10, (A)). This indicates that PN06 effectively inhibits HSC activation and further slows down the liver fibrosis process by inhibiting AXL phosphorylation (Figure 10, (B)).
