The search for improved cytotoxic agents continues to be an important line in the discovery of modern anticancer drugs. Sarcopoterium spinosum (L.) Spach is mentioned in ethnobotanical surveys as a medicinal plant used for the treatment of cancer. The aim of this study is to investigate and to
Tormentic acid has been shown to exert remarkable anti-cancer potential against different cancer cell types. In this study, the anti-cancer potential of tormentic acid was examined in cisplatin-resistant cervical cancer cells (HeLa cells). Further, the effects of tormentic acid on cell ABC transporter overexpression is an important mechanism of multidrug resistance (MDR) and one of the main obstacles to successful cancer treatment. As these proteins actively remove chemotherapeutics from the tumor cells, the pharmacological inhibition of their activity is a possible strategy to
Tormentic acid (TA) is a triterpene isolated from the stem bark of the plant Vochysia divergens and has been reported to exhibit anticancer, anti‑inflammatory and anti‑atherogenic properties. However, the functions of TA in hydrogen peroxide (H2O2)‑induced oxidative stress and inflammation in rat
Anti-inflammatory effects of tormentic acid (TA) were investigated ex vivo and in vivo. TA decreased the paw edema at the 4th and 5thhour after λ-carrageenin (Carr) administration, and increased the activities of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) in the
Chronic myeloid leukemia (CML) is a potentially fatal stem-cell cancer. P-glycoprotein (P-gp/ABCB1) activity has been described as a relevant factor in the chemotherapeutic failure and correlated to a poor prognosis in these malignancies. In the present study, we investigated the mechanism of the
We previously reported that extract of Rosa rugosa root and its active triterpenoids constituents exhibit anti-nociceptive and anti-inflammatory effects in animal models. However, little is known about the effects and the molecular mechanism of the 19α-hydroxyursane-type triterpenoids. Among the
To explore the anticancer compounds from tormentic acid derivatives, a quantitative structure-activity relationship (QSAR) model was developed by the multiple linear regression methods. The developed QSAR model yielded a high activity-descriptors relationship accuracy of 94% referred by regression
An acetaminophen (APAP) overdose can cause hepatotoxicity and lead to fatal liver damage. The hepatoprotective effects of tormentic acid (TA) on acetaminophen (APAP)-induced liver damage were investigated in mice. TA was intraperitoneally (i.p.) administered for six days prior to APAP
Tormentic acid (TA) has been reported to have anticancer, anti-inflammatory and anti-atherogenic properties. However, the effects of TA on neuroinflammation have not been reported. In this study, we investigated whether TA inhibited lipopolysaccharide (LPS)-induced inflammatory response in BV2
BACKGROUND
Rubus niveus Thunb. plant belongs to Rosaceae family and have been used traditionally to treat wounds, burns, inflammation, dysentery, diarrhea and for curing excessive bleeding during menstrual cycle. The present study was undertaken to investigate the in vivo genotoxicity of Rubus
Investigation of the chemical constituents of Salvia judaica growing wild in Jordan led to the isolation and identification of 15 known compounds. These included: luteolin-3'-methyl ether (1), indole-3-carboxyaldehyde (2), p-hydroxybenzaldehyde (3), tricin
Two anti-inflammatory triterpenoids, tormentic acid (TA) and euscaphic acid (EA), were found from the plant Rubus sieboldii. These triterpenoids showed an inhibitory effect against enzymes involved in replication, such as calf DNA polymerase alpha (pol alpha) and rat DNA polymerase beta (pol beta).
Nine triterpene acids, viz., six of the ursane type, ursolic acid (1), corosolic acid (2), 3-epicorosolic acid (3), pomolic acid (4), tormentic acid (5) and hyptadienic acid (6), and three of the oleanane type, oleanolic acid (7), augustic acid (8) and 3-epimaslinic acid (9), among which 1
Rubus chingii Hu, namely "Fu-pen-zi" in Chinese, has been used as a functional food in China for a long time. This study aims to identify its bioactive constituents with antioxidant and anti-tumor properties. R. chingii was extracted with 95% ethanol and then partitioned into four fractions:
