Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Calotropis gigantea (L.) Dryand. (C. gigantea) is a traditional medicinal plant, recognized for its effectiveness in managing diabetes, along with its notable antioxidant, anti-inflammatory, and anticancer properties. Type II diabetes mellitus (T2DM) is characterized by chronic metabolic disorders associated with an elevated risk of hepatocellular carcinoma (HCC) due to hyperglycemia and impaired insulin response. The scientific validation of C. gigantea's ethnopharmacological efficacy offers advantages in alleviating cancer progression in T2DM complications, enriching existing knowledge and potentially aiding future clinical cancer treatments. AIM This study aimed to investigate the preventive potential of the dichloromethane fraction of C. gigantea stem bark extract (CGDCM) against diethylnitrosamine (DEN)-induced HCC in T2DM rats, aiming to reduce cancer incidence associated with diabetes while validating C. gigantea's ethnopharmacological efficacy. MATERIALS AND METHODS Spontaneously Diabetic Torii (SDT) rats were administered DEN to induce HCC (SDT-DEN-VEH), followed by treatment with CGDCM. Metformin was used as a positive control (SDT-DEN-MET). All the treatments were administered for 10 weeks after the initial DEN injection. Diabetes-related parameters, including serum levels of glucose, insulin, and glycosylated hemoglobin (HbA1c), as well as liver function enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase), were quantified. Serum inflammation biomarkers interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were evaluated. Liver tissue samples were analyzed for inflammation protein expression (IL-6, TNF-α, transforming growth factor-β1 (TGF-β1), and α-smooth muscle actin (α-SMA)). Histopathological evaluation was performed to assess hepatic necrosis, inflammation, and fibrosis. Liver cell proliferation was determined using immunohistochemistry for Ki-67 expression. RESULTS Rats with SDT-DEN-induced HCC treated with CGDCM exhibited reduced serum glucose levels, elevated insulin levels, and decreased HbA1c levels. CGDCM treatment also reduced elevated hepatic IL-6, TNF-α, TGF-β1, and α-SMA levels in SDT-DEN-VEH rats. Additionally, CGDCM treatment prevented hepatocyte damage, fibrosis, and cell proliferation. No adverse effects on normal organs were observed with CGDCM treatment, suggesting its safety for the treatment of HCC complications associated with diabetes. Additionally, the absence of adverse effects in SD rats treated with CGDCM at 2.5 mg/kg further supports the notion of its safe usage. CONCLUSIONS These findings suggest that C. gigantea stem bark extract exerts preventive effects against the development of HCC complications in patients with T2DM, expanding the potential benefits of its ethnopharmacological advantages.

Calotropis procera: A double edged sword against glioblastoma, inhibiting glioblastoma cell line growth by targeting histone deacetylases (HDAC) and angiogenesis. Heliyon 2024; 10:e24406. [PMID: 38304784 PMCID: PMC10831610 DOI: 10.1016/j.heliyon.2024.e24406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 12/16/2023] [Accepted: 01/08/2024] [Indexed: 02/03/2024] Open
Abstract
Despite substantial investments in anti-glioblastoma (GBM) drug discovery over the last decade, progress is limited to preclinical stages, with clinical studies frequently encountering obstacles. Angiogenic and histone deacetylase inhibitors (HDACi) have shown profound results in pre-clinical studies. Investigating a multicomponent anti-cancer remedy that disrupts the tumor angiogenic blood vessels and simultaneously disrupts HDACs, while inducing minimal side effects, is critically needed. The crude extracts derived from medicinal plants serve as a renewable reservoir of anti-tumor drugs, exhibiting reduced toxicity compared to chemically synthesized formulations. Calotropis procera is a traditional medicinal plant, and its anticancer potential against many cancer cell lines has been reported, however its antiangiogenic and HDAC inhibitory action is largely unknown. The anticancer activity of methanol leaf extract of C. procera was tested in three types of human glioblastoma cell lines. Wild-type and transgenic zebrafish embryos were used to evaluate developmental toxicity and angiogenic activity. A human angiogenic antibody array was used to profile angiogenic proteins in the U251 GM cell line. A real-time reverse transcriptase polymerase chain reaction (RT PCR) assay was used to detect the differential expression of eleven HDAC genes in U251 cells treated with C. procera extract. The extract significantly reduced the proliferation of all three types of GBM cell lines and the cytotoxicity was found to be more pronounced in U251 GM cells, with an IC50 value of 2.63 ± 0.23 μg/ml, possibly by arresting the cell cycle at the G2/M transition. The extract did not exhibit toxic effects in zebrafish embryos, even at concentrations as high as 1000 μg/ml. The extract also inhibited angiogenic blood vessel formation in the transgenic zebrafish model in a dose-dependent manner. The results from the angiogenic antibody array have suggested novel angiogenesis targets that can be utilized to treat GBM. Real-time RT PCR analysis has shown that C. procrea extract caused an upregulation of HDAC5, 7, and 10, while the mRNA of HDAC1, 2, 3 and 8 (Class I HDACs), and HDAC4, 6, and 9 (Class II) were downregulated in U251 GM cells. The cytotoxicity of the C. procera extract on GBM cell lines could be due to its dual action by regulation of both tumor angiogenesis and histone deacetylases enzymes. Through this study, the C. procera leaf extract has been suggested as an effective remedy to treat GBM with minimal toxicity. In addition, various novel angiogenic and HDAC targets has been identified which could be helpful in designing better therapeutic strategies to manage glioblastoma multiforme in human patients.

Abstract
A bioactivity-guided isolation from the aerial parts of Phyllanthus rheophyticus obtained 17 undescribed ent-cleistanthane-type diterpenoids, namely phyllarheophols A-Q, as well as 12 known analogs. Their structures were characterized by a combination of spectroscopic data interpretation, single-crystal X-ray diffraction and ECD analysis. The anti-inflammatory activities of these compounds were evaluated by measuring their inhibitory effects on NO production in LPS-stimulated RAW264.7 macrophages, and their preliminary structure-activity relationships were also discussed. Further study showed that promising compounds phyllarheophol D and phyacioid B significantly suppressed the expressions of cytokines and nitric oxide synthase through the NF-κB signaling pathway.

An updated pharmacological insight into calotropin as a potential therapeutic agent in cancer. Front Pharmacol 2023; 14:1160616. [PMID: 37138852 PMCID: PMC10149670 DOI: 10.3389/fphar.2023.1160616] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 04/05/2023] [Indexed: 05/05/2023] Open
Abstract
Calotropin is a pharmacologically active compound isolated from milkweed plants like Calotropis procera, Calotropis gigantea, and Asclepias currasavica that belong to the Asclepiadaceae family. All of these plants are recognised as medical traditional plants used in Asian countries. Calotropin is identified as a highly potent cardenolide that has a similar chemical structure to cardiac glycosides (such as digoxin and digitoxin). During the last few years, cytotoxic and antitumor effects of cardenolides glycosides have been reported more frequently. Among cardenolides, calotropin is identified as the most promising agent. In this updated and comprehensive review, we aimed to analyze and discuss the specific mechanisms and molecular targets of calotropin in cancer treatment to open new perspectives for the adjuvant treatment of different types of cancer. The effects of calotropin on cancer have been extensively studied in preclinical pharmacological studies in vitro using cancer cell lines and in vivo in experimental animal models that have targeted antitumor mechanisms and anticancer signaling pathways. The analyzed information from the specialized literature was obtained from scientific databases until December 2022, mainly from PubMed/MedLine, Google Scholar, Scopus, Web of Science, and Science Direct databases using specific MeSH search terms. The results of our analysis demonstrate that calotropin can be a potential chemotherapeutic/chemopreventive adjunctive agent in cancer pharmacotherapeutic management.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Preparations derived from the plant Calotropis procera, have been used for medicinal purpose though the plant is known for its toxic effects. The aerial parts of the plant contain latex in plenty and have been found effective in treating disorders of gastrointestinal system and cancer. AIM OF THE STUDY This study evaluated the efficacy of C. procera dried latex extract prepared in methanol (MeDL) against inflammation and oxidative stress in experimental model of colorectal carcinoma (CRC). MATERIALS AND METHODS Two subcutaneous injections of chemical carcinogen, 1,2-dimethylhydrazine (DMH; 150 mg/kg) were given at an interval of one week to induce CRC in rats. The MeDL (50 and 150 mg/kg) and aspirin (60 mg/kg) were given daily and their effect was evaluated on markers of oxidative stress and inflammation after completion of 8 weeks following second injection of carcinogen. A comparison was made with normal and experimental control groups. The colon tissue levels of glutathione (GSH), thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), nitrite and myeloperoxidase (MPO) were determined. Enzyme-linked immunosorbent assay was performed to determine the levels of prostaglandin E2 (PGE2) and tumor necrosis factor-alpha (TNF-α) and immunohistochemical analysis was performed for IL-1β. RESULTS Induction of cancerous changes in the colon resulted in altered oxidative homeostasis as evident from a reduction in GSH level and SOD activity and rise in TBARS level when compared with normal rats. Elevated levels of nitrite, MPO, TNF-α, PGE2 and immunoreactivity of IL-1β were also observed in these rats. The levels of these markers were normalized when the rats were treated with MeDL or anti-inflammatory drug, aspirin. CONCLUSION This study demonstrates that suppression of oxidative stress and inflammation contributes to the beneficial effect of MeDL in rat model of colon carcinogenesis.

Abstract
Cardiac glycosides (CGs) are good candidates as drug leads in the treatment of cancer because of their structural diversities and potent biological activities. In this study, fifteen CGs including three new ones (1–3) were isolated from Digitalis lanata Ehrh. Their structures were elucidated by HRESIMS, NMR spectroscopic methods, including homonuclear and heteronuclear coupling constant analysis, and acid-catalyzed hydrolysis and derivatization analysis of the sugar chain. The cytotoxic activities of these CGs were evaluated against three human cancer cell lines (A549, HeLa and MCF-7 cell lines), and all of them showed strong activities at nanomolar scale. The flow cytometric analysis indicated that compound 1 induced cell cycle arrest in the G2/M phase. Transcriptome analysis revealed a panel of possible targets for compound 1. RT-PCR and western blot experiments showed that 1 significantly inhibited the expression of vasohibin-2 (VASH2). Moreover, compound 1 restrained angiogenesis in a concentration-dependent manner in the chick embryo chorioallantoic membrane (CAM) model. Cardiac glycosides (CGs) are good candidates as drug leads in the treatment of cancer because of their structural diversities and potent biological activities.![]()
