Ethnopharmacological relevance

Anthocephalus cadamba (Roxb.) Miq. (Family: Rubiaceae) is commonly known as “Kadamba” in Sanskrit and Hindi in India. Various parts of this plant have been used as a folk medicine for the treatment of tumor, wound healing, inflammation and as a hypoglycemic agent.

Aim of study

The purpose of this investigation was to evaluate the antitumor activity and antioxidant status of defatted methanol extract of A. cadamba (MEAC) on Ehrlich ascites carcinoma (EAC) treated mice.

Materials and methods

In vitro cytotoxicity assay has been evaluated by using the trypan blue method. The determination of in vivo antitumor activity was performed by using different EAC cells (2×10⁶ cells, i.p.) inoculated mice groups (n=12). The groups were treated for 9 consecutive days with MEAC at the doses of 200 and 400 mg/kg b.w. respectively. After 24 h of last dose and 18 h of fasting, half of the mice were sacrificed and the rest were kept alive for assessment of increase in life span. The antitumor potential of MEAC was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological parameters and biochemical estimations. Furthermore, antioxidant parameters were assayed by estimating liver and kidney tissue enzymes.

Results

MEAC showed direct cytotoxicity on EAC cell line in a dose dependant manner. MEAC exhibited significant (P<0.01) decrease in the tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice. The hematological profile, biochemical estimations and tissue antioxidant assay were reverted to normal level in MEAC treated mice.

Conclusion

Experimental results revealed that MEAC possesses potent antitumor and antioxidant properties. Further research is going on to find out the active principle(s) of MEAC for better understanding of mechanism of its antitumor and antioxidant activity.

Immunomodulatory and antitumor activity of Piper longum Linn. and piperine

Alcoholic extract of the fruits of the plant Piper longum and its component piperine was studied for their immunomodulatory and antitumor activity. Alcoholic extract of the fruits was 100% toxic at a concentration of 500 microg/ml to Dalton's lymphoma ascites (DLA) cells and 250 microg/ml to Ehrlich ascites carcinoma (EAC) cells. Piperine was found to be cytotoxic towards DLA and EAC cells at a concentration of 250 microg/ml. Alcoholic extract and piperine was also found to produce cytotoxicity towards L929 cells in culture at a concentration of 100 and 50 microg/ml, respectively. Administration of alcoholic extract of Piper longum (10 mg/dose/animal) as well as piperine (1.14 mg/dose/animal) could inhibit the solid tumor development in mice induced with DLA cells and increase the life span of mice bearing Ehrlich ascites carcinoma tumor to 37.3 and 58.8%, respectively. Administration of Piper longum extract and piperine increased the total WBC count to 142.8 and 138.9%, respectively, in Balb/c mice. The number of plaque forming cells also enhanced significantly by the administration of the extract (100.3%) and piperine (71.4%) on 5th day after immunization. Bone marrow cellularity and alpha-esterase positive cells were also increased by the administration of Piper longum extract and piperine.     

Study of the antitumor potential of Bidens pilosa (Asteraceae) used in Brazilian folk medicine

AIM OF THE STUDY: Bidens pilosa (L.) (Asteraceae) is a medicinal plant traditionally used in Brazil for treating conditions that can be related to cancer. Therefore the present study was carried out to evaluate the antitumor activity of extracts obtained from the aerial parts of this plant species. MATERIALS AND METHODS: The crude hydroalcoholic extract (HAE) (water:alcohol, 6:4) and solvent fractions (chloroform=CHCl3,ethyl acetate=EtOAc, methanol=MeOH) were assessed for cytotoxicity assay by the brine shrimp and hemolytic, MTT and NRU assays. The antiproliferative potential of the crude extract and fractions was investigated in vivo using the Ehrlich ascites carcinoma (EAC) in isogenic Balb/c mice that were administered intraperitoneally 150 and 300 mg/kg body weight per day for nine days beginning 24 h after tumor inoculation. RESULTS: In in vitro cytotoxicity using Ehrlich ascites carcinoma cell line assay CHCl3 extract proved to be more toxic than the crude HAE with an IC(50) of 97+/-7.2 and 83+/-5.2 microg/mL to NRU and MTT, respectively. Histomorphological evaluations indicated that the treatment with CHCl3 and HAE extracts significantly reduced (P<0.05) body weight, abdominal circumference, tumor volume, packed cell volume and viable cell count, when compared to EAC control group. Furthermore, nonviable tumor cell count increased significantly (P<0.01) only under treatment with CHCl3 or HAE, and this was accompanied by a marked percentage increase in life span (54.2 and 41.7%, respectively). Biochemical assays revealed that CHCl3 and HAE extracts were also able to decrease serum LDH activity (39.5 and 30.6%) and GSH concentration (94.6 and 50.7%) in ascitic fluid, respectively. CONCLUSION: The chloroform fraction showed the best and methanolic the worst antitumor activity.

Antitumour and anticarcinogenic activity of Phyllanthus amarus extract

Aqueous extract of Phyllanthus amarus (P. amarus) treatment exhibited potent anticarcinogenic activity against 20-methylcholanthrene (20-MC) induced sarcoma development and increased the survival of tumour harboring mice. The extract administration (p.o) was also found to prolong the life span of Dalton's Lymphoma Ascites (DLA) and Ehrlich Ascites Carcinoma (EAC) bearing mice and reduced the volume of transplanted solid tumours. The extract inhibited aniline hydroxylase, a P-450 enzyme. The concentration required for 50% inhibition (IC(50)) was found to be 540 microg/ml. The extract was found to inhibit DNA topoisomerase II of Saccharomyces cerevisiae mutant cell cultures and inhibited cell cycle regulatory enzyme cdc25 tyrosine phosphatase (IC(50-25) microg/ml). Antitumour and anticancer activity of P. amarus may be related with the inhibition of metabolic activation of carcinogen as well as the inhibition of cell cycle regulators and DNA repair.     

A p‐Menth‐1‐ene‐4,7‐diol (EC‐1) from Eucalyptus camaldulensis Dhnh. Triggers Apoptosis and Cell Cycle Changes in Ehrlich Ascites Carcinoma Cells

Anticancer activities of p‐menth‐1‐ene‐4,7‐diol (EC‐1) isolated from Eucalyptus camaldulensis Dhnh. were studied on Ehrlich ascites carcinoma (EAC) cells by MTT (3‐[4,5‐dimethylthiazol‐2‐yl]‐2,5 diphenyl tetrazolium bromide) assay. Anticancer activities also analyzed in EAC‐bearing mice by assessment of cancer growth inhibition, changes in cancer volume, changes in life span, and hematological parameters. Apoptosis was analyzed by fluorescence microscope, DNA fragmentation assay, and flow cytometry. The expression of apoptosis‐related genes, Bcl‐2, Bcl‐X, PARP‐1, p53, and Bax, were analyzed using polymerase chain reaction (PCR). EC‐1 significantly inhibited proliferation of EAC cells in vivo and restored the altered hematological parameters of EAC‐bearing mice. Cytological observation by fluorescence microscope showed apoptosis of EAC cells upon treatment with EC‐1. Also, DNA fragmentation assay revealed EAC cells' apoptosis following EC‐1 treatment. Increased mRNA expressions of p53 and Bax genes and negative expressions of Bcl‐2 and Bcl‐X were observed in cells treated with EC‐1. These findings confirmed the induction of apoptosis by EC‐1. In addition, MTT assay showed dose‐dependent anticancer activity of EC‐1 against EAC cell. Cell cycle analysis revealed that EC‐1 treatment caused suppression of EAC cells at S phase. To conclude, EC‐1 is a novel anticancer compound and showed antiproliferative and apoptotic activities in cellular and mice models. Copyright © 2015 John Wiley & Sons, Ltd.     

Antarth, a polyherbal preparation protects against the doxorubicin-induced toxicity without compromising its Antineoplastic activity

Doxorubicin (DOX), an anthracycline drug widely used for the treatment of various cancers, causes a cumulative dose-dependent cardiotoxicity that is characterized by an irreversible dilated cardiomyopathy and congestive heart failure. Antarth (ANT) a polyherbal preparation was evaluated for its cardioprotective properties against doxorubicin-induced cardiotoxicity in mice. Mice were treated with 25 mg/kg ANT orally once daily for 5 consecutive days before a single intraperitoneal injection of 15 mg/kg doxorubicin. The animals were killed 30 h after DOX treatment. DOX induced a significant elevation in the serum levels of glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), creatine kinase (CK-MB) and lactate dehydrogenase (LDH), indicating its acute cardiotoxicity. The treatment of mice with ANT before DOX administration significantly reduced the serum levels of GPT, GOT, CK-MB and LDH indicating that ANT protected against the DOX-induced cardiotoxicity. Pretreatment of mice with 25 mg/kg ANT inhibited the DOX-induced decline in the antioxidant status. Intraperitoneal injection of 1.25 mg/kg DOX once daily for 9 consecutive days significantly improved the survival of mice bearing Ehrlich ascites carcinoma (EAC). Treatment of EAC with 25 mg/kg ANT alone did not affect the anticancer activity of DOX since ANT did not alter the tumor cell growth, the median survival time and average survival time of tumor bearing mice. The present study demonstrates that ANT protects mice against DOX-induced cardiotoxicity, without compromising the antineoplastic activity of DOX.     

In vitro cytotoxic and antitumor property of Emilia sonchifolia (L.) DC in mice

Methanolic extract of Emilia sonchifolia (Compositae), a folklore medicinal plant, was found to be cytotoxic to Daltons lymphoma (DL), Ehrlich ascites carcinoma (EAC) and mouse lung fibroblast (L-929) cells, but not toxic to normal human lymphocytes, under in vitro conditions. Oral administration of the extract (100 mg/kg, b. wt) to mice reduced the development of both solid and ascites tumors and increased the life span of these tumor bearing mice. Further, the extract inhibited DNA synthesis as judged from a reduction in tritiated thymidine incorporation into DL cells under in vitro conditions.

Preliminary investigation of the radiosensitizing activity of guduchi (Tinospora cordifolia) in tumor-bearing mice

The radiosensitizing activity of dichloromethane extract of guduchi [Tinospora cordifolia (WILLD.) MIERS ex HOOK. F. & THOMS. Family: Menispermaceae (TCE)] in the mice transplanted with Ehrlich ascites carcinoma (EAC) was investigated. The EAC mice received 0, 25, 30, 40, 50 or 100 mg/kg b.wt. TCE 1 h before exposure to 6 Gy hemi-body gamma-radiation and then once daily for another eight consecutive days after irradiation. The EAC mice receiving TCE for the above regimen showed a dose-dependent elevation in tumor-free survival; the highest radiosensitizing activity was observed at 30 mg/kg b. wt. TCE. Treatment of animals with 30 mg/kg b. wt. TCE, 1 h before exposure to 6 Gy of hemi-body gamma irradiation and subsequently once daily for another six consecutive days post-irradiation increased the life span of EAC mice. This is evident by more number of long-term survivors (LTS) as well as survivors beyond 120 days when compared to the group of animals that received TCE after irradiation for six consecutive days. Treatment modality was also altered to assess the radiosensitizing effect of TCE before and after irradiation. Evaluation of glutathione (GSH), glutathione S-transferase (GST) and lipid peroxidation (LPx) in mice treated with TCE 1 h before irradiation and subsequently once daily for another six days showed a significant decline in GSH up to 14 h and GST up to 24 h accompanied by a significant elevation in LPx at 12 h post-irradiation. The radiosensitization of TCE may be due to depletion of glutathione and glutathione-S-transferase, accompanied by elevated levels of lipid peroxidation and DNA damage of tumor cells. Since Tinospora cordifolia is being used in India for treatment of various ailments, it may offer an alternative treatment strategy for cancer in combination with gamma radiation.     

Pretreatment with neem (Azadirachta indica) leaf preparation in Swiss mice diminishes leukopenia and enhances the antitumor activity of cyclophosphamide

Cancer chemotherapy is associated with several life threatening complications, including bone marrow suppression and leucopenia. To overcome this problem, colony stimulating factor (CSF), granulocyte colony stimulating factor (GCSF) and granulocyte macrophage colony stimulating factor (GMCSF), can be used, however, these therapeutics are expensive and have several disadvantages, including tumor growth promoting activities. This study attempted to use an immunostimulatory neem (Azadirachta indica) leaf preparation (NLP) to prevent the cyclophosphamide (CYP) induced reduction in the WBC count. Pretreatment of mice with NLP reduced the extent of leucopenia and neutropenia in normal and tumor bearing CYP treated mice. NLP pretreatment enhanced in vitro tumor cell cytotoxicity by peripheral blood mononuclear cells (PBMC) from CYP treated mice in either normal or tumor bearing conditions. Similarly, NLP pretreatment of mice enhanced the CYP mediated in vivo tumor growth inhibition and survivability of the host. Based on these observations, it is concluded that NLP would be an effective tool to reduce CYP-induced hematological complications.

Ethnopharmacological relevance

India is a rich source of medicinal plants and a number of plant extracts are used against diseases in various systems of medicine such as Ayurveda, Unani and Siddha. Only a few of them have been scientifically explored. One of such plants is Ammannia baccifera L., traditionally used as an antitumor agent.

Aim of the study

The objective of the present study was to explore the anticancer activity of the methanol extract of A. baccifera against Dalton's ascites lymphoma (DAL)-bearing Swiss albino mice and in vitro cytotoxicity against human cervical cancer cell line (HeLa).

Materials and methods

In vitro cytotoxic effects of A. baccifera was evaluated against HeLa and NIH 3T3 cells using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] method. Anticancer activity of the extract was evaluated in Swiss albino mice against DAL cell line at the doses of 100 and 200 mg/kg p.o. The extract was administered to animals for 14 consecutive days. After 12 h fasting from last dose, the mice were sacrificed and the anticancer effect of A. baccifera was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological parameters and certain antioxidant biochemical parameters against DAL bearing control group.

Results

The extract of A. baccifera was cytotoxic to the HeLa cancer cell line but relatively non-toxic to the normal cell line NIH 3T3. A. baccifera extract treatment resulted in significant decreases in tumor volume, viable cell count and tumor weight and enhanced the life span of DAL bearing mice. Hematological parameters such as RBC, hemoglobin and lymphocyte count reverted to normal level in A. baccifera treated mice. The extract also significantly (p<0.05) decreased the levels of lipid peroxidation and increased the activities of GSH, GPx, SOD and CAT. The anticancer effects of the A. baccifera extract is comparable with that of the standard drug 5-Fluorouracil.

Conclusion

The results showed that the methanol extract of A. baccifera is effective in inhibiting the tumor growth in ascetic models that is comparable to 5-fluorouracil. This plant has potential in the development of anticancer therapy and this study scientifically validated the folklore use of this plant.

Antitumor activity of total alkaloid fraction of solanum pseudocapsicum leaves

The total alkaloid fraction of the methanolic extract of Solanum pseudocapsicum leaves was tested for its in-vivo antitumor activity against Dalton's Lymphoma Ascites model in mice. The total alkaloid fraction at 2.5 and 5.0 mg/kg body weight doses exhibited antitumor activity as revealed by the significant increase in the mean survival time and the percentage increase in life span of tumor bearing mice. The antitumor activity observed may be due to its cytotoxic properties. However the treatment caused a significant decrease in the body weight below the normal indicating the toxicity of the treatment.
