Antiproliferative Activity and Apoptotic Mechanisms of β-Sitosterol and Its Derivatives as Anti-Breast Cancer Agents: In Silico and In Vitro

Introduction

Breast cancer has become the most frequently diagnosed cancer worldwide. Beta-sitosterol and its derivatives have been explored for its anticancer properties. Therefore, this study aims to analyze the testing procedure carried out on MCF7 and MDA-MB-231 breast cancer cells, as well as MCF 10A non-cancerous breast epithelial cells.

Methods

The compounds tested included β-sitosterol and its derivatives: 3β-galactose sitosterol, sitostenone, 3β-glucose sitosterol, poriferasta-5, 22E, 25-trien-3β-ol, and 22-dehydrocholesterol. Cytotoxicity assay was conducted using the PrestoBlue™ Cell Viability Reagent on MCF-7, MDA-MB-231, and MCF 10A cells. The compounds with the highest and lowest cytotoxicity were further analyzed for their mechanisms of action through cell morphology assessments and molecular docking studies. mRNA expression levels were also evaluated to confirm the findings.

Results

The results showed that 3β-glucose sitosterol exhibited the most promising cytotoxic activity with IC50 values against MCF7, MDA-MB-231 breast cancer cells, and MCF 10A non-cancerous cells of 265 µg/mL, 393.862 µg/mL, and 806.833 µg/mL, respectively. Molecular docking simulations showed that the compound is bound to estrogen receptor beta and caspase-3, suggesting a potential mechanism of action as evidenced by the best binding energy of -6.94 kcal/mol and inhibition constant values of 8.16 μM. Furthermore, gene expression analysis confirmed the induction of apoptosis through the upregulation of caspase-9 and caspase-3 mRNA expression.

Conclusion

Based on the results, β-sitosterol and its derivatives, particularly 3β-glucose sitosterol, show as the most promising potential adjuvant therapy for hormone-positive breast cancer.

Anti-proliferative effects of a polyherbal formulation on HL-60, HCT-116, and HeLa cell lines: a docking simulation and response surface design-aided study

Cancer is a complex global health challenge that requires novel and holistic approaches to treatment and prevention. Polyherbal medicines, composed of multiple plants with historical use in traditional medicine, have gained popularity due to their safety, cost-effectiveness, and accessibility. However, selecting the right plants and determining optimal combinations for enhanced biological effects remains challenging. To address this, a molecular docking study was conducted, targeting proteins implicated in cancer pathogenesis. The study identified bioactive compounds with strong binding energies, guiding the selection of polyherbal formulations for further experimentation. Using response surface methodology, various combinations of plant extracts were screened for their antioxidant properties and phytochemical content. Among the formulations tested, PHEE (Polyherbal Ethanolic Extract), comprising 70% soursop leaf, 5% jackfruit leaf, 5% orange peel, 15% citrus juice, and 5% apple fruit ethanolic extracts, exhibited the most potent biological activities, followed by SLEE (Soursop Leaf Ethanolic Extract), a 100% soursop leaf ethanolic extract. Design Expert Software predicted soursop leaf extract as a key contributor to desirable outcomes, attributed to its rich phytochemical composition. Cell-based assays revealed varying cytotoxic effects of the extracts on leukemia cells, with PHEE showing the highest potency (IC50 = 2.50 μg/mL), followed closely by SLEE (IC50 = 2.90 μg/mL). These effects are potentially due to the abundant acetogenins and flavonoids present in the extracts. However, caution is warranted regarding their cytotoxicity to normal cells. Apoptotic studies confirmed the ability of both PHEE and SLEE to induce programmed cell death, further supporting their potential as anticancer agents. This research underscores the importance of strategic plant combinations in polyherbal formulations and highlights PHEE as a promising candidate for further investigation in cancer treatment.

Elucidating the potential of Annona muricata L. grown in Sri Lanka to be used in developing an anticancer drug against colorectal and breast cancers

BACKGROUND

Since ancient times many traditional medicine systems around the world have been using different parts of Annona muricata L. (AM), to treat cancer. Indeed, numerous in vitro and in vivo studies also have shown anticancer properties of different solvent extracts of different parts of AM. Even the same part of the plant has shown different levels of anticancer properties based on geographical variations. Therefore, in the present study, the anticancer potential of the leaves, fruit pulp and the fruit peel of the AM that is grown in Sri Lanka was comparatively analyzed with the intention of identifying the most suitable part to be developed into a nutraceutical with anticancer effects.

METHODS

Freeze-dried aqueous extracts of immature leaves (ILAM), mature leaves (MLAM), pulp (PAM) and peel (PLAM) of AM were analyzed for their antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and 2,2-azinobis-3-ethylbenzothiozoline-6-sulfonic acid (ABTS) cation decolorization assays. Their cytotoxicity on breast cancer (MCF-7) cells, colorectal adenocarcinoma (DLD-1) cells and normal human gingival fibroblasts (HGF-1) were determined by the 3-(4,5- dimethylthiazole-2-yl)-2,5-diphenyl-tetrazoliumbromide (MTT) assay. Their effect on mRNA expression of proapoptotic (Bax and caspase-7) and cell cycle arresting (p21) genes was analyzed by RT- qPCR in the same cell lines.

RESULTS

ILAM demonstrated the highest antioxidant activity in both DPPH and ABTS assays followed by MLAM, PLAM and PAM. In the MTT assay, both ILAM and MLAM demonstrated strong cytotoxic activity against MCF-7 and DLD-1 cell lines while there were no cytotoxic effects on the normal human cell line HGF-1. Both ILAM and MLAM demonstrated concentration-dependent upregulation of mRNA expression of cell cycle arresting gene p21 and apoptosis inducing genes Bax and caspase-7 in MCF-7 and DLD-1 cells.

CONCLUSION

The AEAM leaves grown in Sri Lanka has significantly higher antioxidant activity as well as selective cytotoxic effects on MCF-7 and DLD-1 cancer cells compared to its PL and P counterparts. Further, the AEAM leaves induced mRNA expression of the anticancer genes p21, Bax and caspase-7, indicating its potential to be developed into an anticancer drug against breast and colorectal cancer.

Investigating the Medicinal Potential of Lavatera cashmeriana Leaf Extract: Phytochemical Profiling and In Vitro Evaluation of Antimicrobial, Antioxidant, and Anticancer Activities

This study investigated the medicinal potential of Lavatera cashmeriana, a plant traditionally known for its therapeutic properties. The aim was to identify the phytocompounds in L. cashmeriana leaf extract and evaluate its antibacterial, antioxidant, and anticancer effects. Gas chromatography-mass spectrometry analysis was employed to characterize the phytochemical composition of the ethanol extract derived from L. cashmeriana leaves. The antimicrobial potential was assessed through the well diffusion technique, targeting Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans. The 2,2-diphenyl-1-picrylhydrazyl assay was conducted to assess antioxidant capabilities, while cytotoxicity against the A549 cancer cell line was determined via the MTT assay. GC-MS analysis identified ten different compounds, with phytol, 1-Eicosanol, and 2,6,10-trimethyl,14-ethylene-14-pentadecne being the most prevalent. The extract exhibited notable antimicrobial efficacy against all bacteria with MIC values ranging from 62.5 to 250 µg/mL. However, C. albicans did not respond. The extract exhibited antioxidative properties with an IC50 value of 86 µg/mL and cytotoxicity with an IC50 value of 69.95 µg/mL against the A549 cancer cell line. The results derived from this study supported the historical use of L. cashmeriana as a medicinal plant and suggested that it can potentially treat a wide range of medical ailments. The identified phytocompounds and the demonstrated antibacterial, antioxidant, and anticancer effects provide scientific evidence for its medicinal properties. However, further investigations are needed to fully understand its safety profile, efficacy, and mechanism of action before recommending it for therapeutic purposes.

Untargeted metabolomics using UHPLC-Q-Orbitrap HRMS for identifying cytotoxic compounds on MCF-7 breast cancer cells from Annona muricata Linn leaf extracts as potential anticancer agents

INTRODUCTION

The leaves of Annona muricata L., known as "soursop" or "sirsak" in Indonesia, are used traditionally for cancer treatment. However, the bioactive components remain largely unidentified.

OBJECTIVE

This study used untargeted liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based metabolomics to identify potential cytotoxic compounds in A. muricata leaf extracts on MCF-7 breast cancer cells in vitro.

METHODS

A. muricata leaves were macerated with water, 99% ethanol, and aqueous mixtures containing 30%, 50%, and 80% ethanol. Cytotoxic activity of the extracts against MCF-7 breast cancer cells was determined using the MTT assay. Ultra-high-performance liquid chromatography-Q-Orbitrap high-resolution mass spectroscopy (UHPLC-Q-Orbitrap-HRMS) was used to characterize the metabolite composition of each extract. The correlations between metabolite profile and cytotoxic activities were evaluated using orthogonal partial least square discriminant analysis (OPLS-DA). The binding of these bioactive compounds to the tumorigenic alpha-estrogen receptor (3ERT) was then evaluated by in silico docking simulations.

RESULTS

Ninety-nine percent ethanol extracts demonstrated the greatest potency for reducing MCF-7 cell viability (IC50 = 22 μg/ml). We detected 35 metabolites in ethanol extracts, including alkaloids, flavonoids, and acetogenins. OPLS-DA predicted that annoreticuin, squadiolin C, and xylopine, and six unknown acetogenin metabolites, might reduce MCF-7 cell viability. In silico analysis predicted that annoreticuin, squadiolin C, and xylopine bind to 3ERT with an affinity comparable to doxorubicin.

CONCLUSION

Untargeted metabolomics and in silico modeling identified cytotoxic compounds on MCF-7 cells and binding affinity to 3ERT in A. muricata leaf extracts. The findings need to be further verified to prove the screening results.

Cytotoxic potential of Curcuma caesia rhizome extract and derived gold nanoparticles in targeting breast cancer cell lines

Among all types of cancer, breast cancer is the most aggressive, as it is responsible for most of the cancer related death of women. Though several medical therapies are available, the scenario of curing such disease is not favorable. Therefore, there is an urgent need to find alternatives to deal with it. The knowledge of ethnopharmacy might give some better solution to mitigate such deadly diseases. Here, we are using the rhizome of Curcuma caesia Roxb. (Black turmeric), as well as gold nanoparticles (GNPs) synthesized with it to check their specific cytotoxic potentiality against breast cancer cell lines. In our study, ethanolic extract was used to evaluate the cytotoxic effect of the rhizome. GNPs were synthesized by using the same extract and characterized by UV-Vis spectroscopy (UV-Vis), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Thermo gravimetric analysis (TGA). The TEM, XRD, FTIR and TGA results revealed the successful synthesis and capping of GNPs. The UV-Vis Spectrum showed a sharp and narrow absorption peak at 550 nm and HRTEM confirmed both the stability and successful synthesis of the nanoparticles. The MTT assay of the crude extract revealed strong cytotoxicity against breast cancer cell lines viz. MCF-7 (ER+) and MDA MB-231 (Triple Negative Breast Cancer, TNBC) by showing IC50 values as 15.70 ± 0.029 and 21.57 ± 0.031 μg/mL respectively. For extract mediated GNPs, the IC50 values were found to be 6.44 ± 0.045 and 5.87 ± 0.031μg/mL respectively in both breast cancer cell lines. As the IC50 value for GNPs was found to be much lower than that of crude extract, it indicates a higher efficiency of the GNP. However, both the rhizome extract and its mediated GNPs showed more toxicity towards MDA MB-231 (TNBC) cell lines. It was also observed that the GNPs showed more toxicity towards TNBC cell lines compared to the rhizome extract. No toxicity was found in case of other cell lines such as L 929 and HeLa for both crude extract as well as for GNPs. These observations suggests that both the crude rhizome extract and its derived GNPs exhibit selective cytotoxic potential against breast cancer cell lines, which might be exploited for target specific treatment. Moreover, with an understanding of the mechanism behind the GNPs therapeutic efficiency, it can be developed as a personalized therapy to treat such type of cancers.

Anti-cancer effects of green synthesized gold nanoparticles using leaf extract of Annona muricata. L against squamous cell carcinoma cell line 15 through apoptotic pathway

Background

Oral cancer remains one of the most dreadful diseases in developing nations. Currently, there has been a rise in the prevalence of tongue squamous cell carcinoma (SCC), with a poor prognosis. The use of standard treatment approaches against oral cancer patients brings about several side effects. In recent years, nanomedicine has provided a versatile platform for developing new targeted therapeutic modalities. However, safety remains a concern in the synthesis of nanoparticles (NPs). Therefore, the present study aims to synthesize safer phytoconstituent-mediated gold NPs (AuNPs) utilizing leaf extracts of Annona muricata, where the biochemical components of the plant leaf act as the reducing and capping agents in the synthesis of NPs, and to evaluate its anti-cancer activity against SCC.

Materials and Methods

In this in vitro experimental study, AuNPs were synthesized through an effective, simple, and ecologically sound green synthesis method. After characterization of these synthesized AuNPs, in vitro assays such as 3-(4, 5-dimethylthiazole2-yl)-2, 5-biphenyl tetrazolium bromide, wound healing, and clonogenic assays were carried out to investigate the anti-cancer potential of green synthesized AuNPs in the human tongue SCC cell line (SCC-15), and the possible mechanism of action was evaluated through gene and protein expression analysis of Bax, Bcl-2, and p53 genes. The results were expressed as mean ± standard deviation using Statistical Package for Social Sciences (SPSS) 20.0 software and Student's t-test was performed for experimental data. P ≤0.05 were considered statistically significant.

Results

The in vitro assays demonstrated that the synthesized AuNPs are exhibiting anti-cancer activity by apoptosis of SCC-15 cells in a dose-dependent manner. Further, it also revealed a highly significant decrease in anti-apoptotic Bcl-2 gene expression, whereas pro-apoptotic genes p53 and Bax revealed a highly significant increase, which is statistically significant compared to the control (P < 0.05).

Conclusion

Our findings demonstrated that the AuNPs synthesized from A. muricata leaf extract could act as a novel anticancer agent, particularly against SCC, after further scrutiny.

Anti-cancer Application of Nat-ZnFe2O4 Nanoparticles on 2D Tumor Models

Metal/Metal Oxide nanoparticles (M/MO NPs) exhibit potential biomedical applications due to their tunable physicochemical properties. Recently, the biogenic synthesis of M/MO NPs has gained massive attention due to their economical and eco-friendly nature. In the present study, Nyctanthes arbor-tristis (Nat) flower extract-derived Zinc Ferrite NPs (Nat-ZnFe2O4 NPs) were synthesized and physicochemically characterized by FTIR, XRD, FE-SEM, DLS, and other instruments to study their crystallinity, size, shape, net charge, presence of phytocompounds on NP's surface and several other features. The average particle size of Nat-ZnFe2O4 NPs was approx. 25.87 ± 5.67 nm. XRD results showed the crystalline nature of Nat-ZnFe2O4 NPs. The net surface charge on NPs was -13.28 ± 7.18 mV. When tested on mouse fibroblasts and human RBCs, these NPs were biocompatible and hemocompatible. Later, these Nat-ZnFe2O4 NPs exhibited potent anti-neoplastic activity against pancreatic, lung, and cervical cancer cells. In addition, NPs induced apoptosis in tested cancer cells through ROS generation. These in vitro studies confirmed that Nat-ZnFe2O4 NPs could be used for cancer therapy. Moreover, further studies are recommended on ex vivo platforms for future clinical applications.

LCMS/MS Phytochemical Profiling, Molecular, Pathological, and Immune-Histochemical Studies on the Anticancer Properties of Annona muricata

Annona muricate is a tropical plant that is well-known for its edible fruit of therapeutic interest. LCMS/MS analyses were applied to identify phytoconstituents of the ethanolic extract of the whole fruits and the aqueous extract of the edible fruit part, in addition to the investigation of their anticancer properties against Ehrlich ascites carcinoma (EAC) in male albino mice. LCMS/MS analyses resulted in the identification of 388 components, representing a wide array of classes of compounds, including acetogenins as the major constituents, alkaloids, flavonoids, and phenolics. Among them, four compounds were tentatively characterized as new compounds (1-4), including an acid derivative, protocatechuic-coumaroyl-quinic acid (1), and three flavonoid derivatives, dihydromyricetin galloyl hexoside (2), apigenin gallate (3), and dihydromyricetin hexouronic acid hexoside (4). Induction with EAC cells resulted in abnormalities in the gene expression of pro-apoptotic genes (Bax and caspase-3) and anti-apoptotic gene (Bcl-2) in the tumor mass. Moreover, microscopic, histopathological, and immune-histochemical examinations of the tumor mass and liver tissues exhibited extensive growth of malignant Ehrlich carcinoma cells and marked hydropic degeneration of hepatocytes and infiltration by tumor cells to liver tissue with marked inflammatory reaction. These abnormalities were markedly ameliorated aftertreatment of EAC mice with A. muricata extracts.

Background

Oral cancer still represents the leading cause of mortality in India. Due to the drawbacks of current treatment options, a safe, low-cost therapy is the need of the hour. Recently, novel plant extracts with anti-cancer properties have gained greater attention. One among them is Annona muricata and its leaf extract, which has been studied for its anti-cancer effect against various cancers. However, studies on oral cancer cells are very much limited and hence the study.

Aims

To evaluate the cytotoxic, anti-proliferative, anti-metastatic and pro-apoptotic effect of aqueous leaf extract of Annona muricata (ALEAM) against SCC-15 cell lines through in vitro assays.

Materials and Methods

In vitro assays such as MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide], colony formation and wound healing assays were performed. Furthermore, to evaluate the underlying mechanism, gene and protein expression analysis of apoptotic/anti-apoptotic marker genes Bax, P53 and Bcl2, were done using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analysis. Student's t-test has been performed for analysis of experimental data.

Results

The results showed that ALEAM exhibited significant cytotoxic activity in a dose-dependent manner as well as inhibited colony formation and cell migration. The pro-apoptotic properties were affirmed by a highly significant drop in Bcl-2 gene expression and a highly significant rise in P53 and Bax genes in the study group compared to the control (P < 0.05).

Conclusion

The current study provides evidence that ALEAM has the potential to be developed as a novel anti-cancer drug for the treatment of SCC after further clinical studies.

The use of African medicinal plants in cancer management

Cancer is the third leading cause of premature death in sub-Saharan Africa. Cervical cancer has the highest number of incidences in sub-Saharan Africa due to high HIV prevalence (70% of global cases) in African countries which is linked to increasing the risk of developing cervical cancer, and the continuous high risk of being infected with Human papillomavirus In 2020, the risk of dying from cancer amongst women was higher in Eastern Africa (11%) than it was in Northern America (7.4%). Plants continue to provide unlimited pharmacological bioactive compounds that are used to manage various illnesses, including cancer. By reviewing the literature, we provide an inventory of African plants with reported anticancer activity and evidence supporting their use in cancer management. In this review, we report 23 plants that have been used for cancer management in Africa, where the anticancer extracts are usually prepared from barks, fruits, leaves, roots, and stems of these plants. Extensive information is reported about the bioactive compounds present in these plants as well as their potential activities against various forms of cancer. However, information on the anticancer properties of other African medicinal plants is insufficient. Therefore, there is a need to isolate and evaluate the anticancer potential of bioactive compounds from other African medicinal plants. Further studies on these plants will allow the elucidation of their anticancer mechanisms of action and allow the identification of phytochemicals that are responsible for their anticancer properties. Overall, this review provides consolidated and extensive information not only on diverse medicinal plants of Africa but on the different types of cancer that these plants are used to manage and the diverse mechanisms and pathways that are involved during cancer alleviation.

Natural biomolecules and derivatives as anticancer immunomodulatory agents

Despite advancements in chemotherapy, the issue of resistance and non-responsiveness to many chemotherapeutic drugs that are currently in clinical use still remains. Recently, cancer immunotherapy has gathered attention as a novel treatment against select cancers. Immunomodulation is also emerging as an effective strategy to improve efficacy. Natural phytochemicals, with known anticancer properties, been reported to mediate their effects by modulating both traditional cancer pathways and immunity. The mechanism of phytochemical mediated-immunomodulatory activity may be attributed to the remodeling of the tumor immunosuppressive microenvironment and the sensitization of the immune system. This allows for improved recognition and targeting of cancer cells by the immune system and synergy with chemotherapeutics. In this review, we will discuss several well-known plant-derived biomolecules and examine their potential as immunomodulators, and therefore, as novel immunotherapies for cancer treatment.
