Lupeol, a triterpene, possesses beneficial effects like anti-inflammatory and anti-cancer properties. Binding of lupeol and its derivative (phytochemicals) to plasma proteins such as human serum albumin (HSA) and α-1-acid glycoprotein (AGP) is a major determinant in the disposition of drugs. Cytotoxic studies with mouse macrophages (RAW 246.7) and HeLa cell lines revealed anti-inflammatory and ...

Overexpression of cellular FLICE-like inhibitory protein (cFLIP) is reported to confer chemoresistance in pancreatic cancer (PaC) cells. This study was designed to investigate the effect of lupeol, a dietary triterpene, on (a) apoptosis of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) therapy-resistant PaC cells overexpressing cFLIP and (b) growth of human pancreatic tumor xen...

The present study investigates the antinociceptive properties of lupeol in models of inflammatory and post-operative pain, as well as its mechanisms of action. The effects of lupeol were tested against acetic acid-induced writhing, formalin test, carrageenan-induced hyperalgesia, and post-operative pain model. Cytokine levels were determined by ELISA. Mice motor performance was evaluated in the...

PURPOSE Conventional therapies to treat prostate cancer (CaP) of androgen-dependent phenotype (ADPC) and castration-resistant phenotype (CRPC) are deficient in outcome which has necessitated a need to identify those agents that could target AR for both disease types. We provide mechanism-based evidence that lupeol (Lup-20(29)-en-3b-ol) is a potent inhibitor of androgen receptor (AR) in vitro an...

PURPOSE Poor prognosis of metastatic melanoma mandates the development of novel strategies for its treatment and prevention. In this study, the effect of lupeol, a diet-based triterpene, was determined on the growth and tumorigenicity of human melanoma cells in vitro and in vivo. EXPERIMENTAL DESIGN Normal human melanocytes, and human metastatic (451Lu) and nonmetastatic (WM35) cells were tre...

Canine melanoma is the most common oral malignant tumor reported in the field of veterinary medicine. We found that lupeol, a lupine triterpene, inhibited mouse melanoma cell growth in vitro and in vivo by inducing cell differentiation. In the present study, we examined the differentiation-inducing activities of lupeol on 4 canine melanoma cells in vitro and in vivo. The induction of canine mel...

Recently, one third of the world’s population is infected with Mycobacterium tuberculosis and 8 million new and relapse cases of tuberculosis are reported every year. The emergence of new cases, the increased incidence of multidrug resistant strains of M. tuberculosis, and the adverse effects of first and second-line antituberculosis drugs have led to renewed research interest in natural produc...

In prostate cancer, a fine balance between cell proliferation and apoptotic death is lost, resulting in increased cellular mass and tumor progression. One approach to redress this imbalance and control this malignancy is its preventive intervention through the use of dietary natural agents. Here, we investigated the growth-inhibitory effect and associated mechanisms of Lupeol, a triterpene pres...

Asthma is a chronic inflammatory disease of the airways associated with a Th2 immune response. Despite their side effects, corticosteroids are the most used and effective drugs for treatment of asthma. In this work we investigated the efficacy of lupeol, a triterpenoid isolated from Lonchocarpus araripensis [corrected] Benth. (Fabaceae), in the treatment of bronchial asthma in BALB/c mice immun...

Two new long-chain alkanoic acid esters of lupeol were isolated together with known triterpenoids, alpha-amyrin, beta-amyrin, cycloartenol, lanosta-7,24-diene-3beta-ol and lupeol from Alecrim-propolis collected in Brazil. The structures were characterized by spectroscopic means.
