triterpene/sarcoma

Betulinic acid (BA) is a naturally occurring lupane-type triterpene which exhibits a variety of biological activities including potent cytotoxic properties. On the basis of the structural similarity to BA, two lupane derivatives namely lup-20(29)-ene-3beta,30-diol (1) and

BACKGROUND In Brazil, latex of Himatanthus drasticus is used to treat inflammation, wound healing and cancer. The present study evaluated the antitumoral potential of H. drasticus latex (HdCL) in Sarcoma 180-bearing mice (S180). METHODS HdCL was obtained in Crato-CE, Brazil. Qualitative

Triterpene acids (TAs) are the major bioactive constituents in the medicinal fungus Ganoderma lingzhi. However, fermentative production of TAs has not been optimized for commercial use, and whether the TAs isolated from G. lingzhi submerged culture mycelia possess antitumor activity needs to be

BACKGROUND The hydrophobic triterpenes, oleanolic and betulinic acid as well as the hydrophilic mistletoe lectins and viscotoxins possess anticancer properties. They do all occur in combination in European mistletoe (Viscum album L.). Commercial Viscum album L. extracts are aqueous, excluding the

Ewing sarcoma is the second most common bone cancer in children and adolescents, with poor prognosis and outcome in ~70% of initial diagnoses and 10-15% of relapses. Hydrophobic triterpene acids and hydrophilic lectins and viscotoxins from European mistletoe (Viscum album L.) demonstrate anticancer

Three new triterpene glycosides, intercedensides A (1), B (2), and C (3), were isolated from the sea cucumber Mensamria intercedens Lampert, which is found in the South China Sea, and their structures have been elucidated by spectroscopic analysis (NMR and ESIMS) and chemical transformations.

Bioassay-guided methods were used to test the antitumor activity of methanol extract of the whole plant of Bacopa monniera (L.) Wettst. and four different fractions (petroleum ether, CHCl(3), EtOAc, and n-BuOH fractions) of the methanol extract. Among the five crude samples, n-BuOH fraction was

The effect of the increased levels of cholesterol in ascites tumor cells of mouse sarcoma 37 on the cytochemical activity of 4 triterpene glycosides was studied. A definite correlation between the increase in the cholesterol level in the cells and the glycoside activity was noted. The effect

Three new lanostante-type triterpene aldehydes, named lucialdehydes A-C (1-3), were isolated from the fruiting bodies of Ganoderma lucidum, together with ganodermanonol (4), ganodermadiol (5), ganodermanondiol (6), ganodermanontriol (7), ganoderic acid A (8), ganoderic acid B8 (9), and ganoderic

OBJECTIVE To study the antitumor activities of the triterpene glycoside colochiroside A (CA) from the sea cucumber Colochirus anceps. METHODS The tests of antitumor activities in vitro and in vivo were applied to demonstrate the effect of CA. RESULTS The preliminary cytotoxic assay of CA exhibited

Several important biological activities have been attributed to the pentacyclic triterpene ursolic acid (UA), being its antitumoral effect extensively studied in human adenocarcinomas. In this work, we focused on the efficacy and molecular mechanisms involved in the antitumoral effects of UA, as

The pentacyclic triterpenes oleanolic acid (OLA) and maslinic acid (MLA) are natural compounds present in many plants and dietary products consumed in the Mediterranean diet (e.g., pomace and virgin olive oils). Several nutraceutical activities have been attributed to OLA and MLA, whose antitumoral

It has been reported that pisosterol was active against cancer cells but lacked activity on the development of sea urchin eggs. Recently, it was reported that pisosterol induces differentiation in leukemia cell line. The present study evaluated the in vivo antitumor activity of pisosterol a

Phytochemical and pharmacological studies of Croton cajucara were oriented by traditional medicine. The stem bark of the mature plant is a rich source of clerodane-type diterpenes: trans-dehydrocrotonin (DCTN), trans-crotonin (CTN), cis-cajucarin B, cajucarin A, cajucarinolide and two novel

ETHNOPHARMACOLOGICAL REVELANCE: Pulsatilla chinensis (Bunge)Regel has been used as adjuvant in chemotherapy in traditional Chinese medicine. 23-Hydroxybetulinic acid, an isolated pentacyclic triterpene, is the major active constituent of Pulsatilla chinensis (Bunge) Regel. OBJECTIVE To evaluate the
