In an attempt to develop potent and selective antitumor agents, a series of novel thiosemicarbazones derived from a natural monoterpene R-(+)-limonene was synthesized and their antitumor activity was evaluated. Overall, the majority of tested compounds exhibited considerable inhibitory effects on
The monoterpene d-limonene is a naturally occurring chemical which is the major component in oil of orange. Currently, d-limonene is widely used as a flavor and fragrance and is listed to be generally recognized as safe (GRAS) in food by the Food and Drug Administration (21 CFR 182.60 in the Code of
OBJECTIVE
To investigate the effects and mechanism of d-limonene on the growth and metastasis of gastric cancer in vivo.
METHODS
Metastatic model simulating human gastric cancer was established by orthotopic implantation of histologically intact human tumor tissue into gastric wall of nude mice. One
OBJECTIVE
To identify the chemical constituents of volatile oil from blood orange (Citrus sinensis (L) Osbeck) and understand the possible mechanisms of inhibition of colon cancer cell proliferation.
METHODS
Volatile oil was obtained from blood oranges by hydro-distillation. Nineteen compounds were
D-limonene is recognized as a potential chemotherapeutic agent, however, the details of this mechanism remain unclear. In this study, we investigated the effects of d-limonene on colon cancer cell viability and its potential mechanism of action in vitro. After 48 h of treatment, d-limonene
Perillyl alcohol is a natural product from cherries and other edible plants. Perillyl alcohol and d-limonene, a closely related dietary monoterpene, have chemotherapeutic activity against pancreatic, mammary, and prostatic tumors. In addition, perillyl alcohol, limonene, and other dietary
Limonene is a farnesyl transferase inhibitor that has shown antitumor properties. The drug had been given orally to cancer patients. Plasma and urine samples collected from the patients were examined by reversed-phase HPLC-atmospheric pressure chemical ionization and electrospray ionization MS. The
BACKGROUND
Citrus bioactive compounds, as active anticancer agents, have been under focus by several studies worldwide. However, the underlying genes responsible for the anticancer potential have not been sufficiently highlighted.
OBJECTIVE
The current study investigated the gene expression profile
In a 2-year carcinogenesis bioassay, d-limonene (dL) induced kidney tumors in male F344 rats, but not in female F344 rats or either sex of mice, d-Limonene-1,2-oxide, a metabolite of dL, has been shown to bind reversibly the male rat-specific urinary protein, alpha2u-globulin (alpha 2u-G), lysosomal
Limonene, a monocyclic monoterpene, occurs naturally in orange peel oil. It has been shown to exhibit both chemopreventive and chemotherapeutic activity without toxicity in rodent models. In this study we examined the effect of limonene both at maximally optimal and suboptimal doses and in
Limonene is a lipophilic monoterpene found in high levels in citrus peel. Limonene demonstrates anticancer properties in preclinical models with effects on multiple cellular targets at varying potency. While of interest as a cancer chemopreventive, the biologic activity of limonene in humans is
d-Limonene has efficacy in preclinical models of breast cancer, causing > 80% of carcinomas to regress with little host toxicity. We performed a pilot study on healthy human volunteers to identify plasma metabolites of limonene and to assess the toxicity of supradietary quantities of d-limonene.
The primary purpose of the current study was to investigate the antitumor activity of limonene which is a plant monoterpene along with evaluating its effects on cell apoptosis, cell cycle phase distribution, cell migration and invasion.The cell BACKGROUND
Clinical trials have shown that docetaxel combined with other novel agents can improve the survival of androgen-independent prostate cancer patients. d -Limonene, a non-nutrient dietary component, has been found to inhibit various cancer cell growths without toxicity. We sought to
UNASSIGNED
d-limonene is a plant extract with widespread application, and it has been recently reported to have antiproliferative and proapoptotic effects on cancer cells. However, the mechanisms by which d-limonene achieves these effects, especially in lung cancer, are not entirely clear.
