Bioactive derivatives from the camphor laurel tree, Cinnamomum camphora, are posited to exhibit chemopreventive properties but the efficacy and mechanism of these natural products are not fully understood. We tested an essential-oil derivative, camphor white oil (CWO), for anti-tumor activity in a
Drug resistance is a major cause of cancer treatment failure. Most cancer therapies involve multiple agents, to overcome it. Compounds that exhibit strong anti-tumor effect without damaging normal cells are more and more in the focus of research. Chemotherapeutic drugs, combining Five silver camphor complexes of formulae [Ag2(L)(L')2] (1,3,5) or [Ag(L)2(L')] (2,4) were synthesized from silver nitrate and the suitable camphor carboxylate (L1) or camphor carboxamides (L3, L4). The complexes were characterized by elemental analysis and spectroscopic techniques (NMR, FTIR, XPS).
A variety of beta-diketones were evaluated for their cytotoxic profiles against oral human normal and tumor cells. Among 22 compounds (BD1-22) tested, the cytotoxicity of 3-formylchromone (BD17) (CC50=7.8 microg/mL) against human oral squamous cell carcinoma (HSC-2) cells was higher than that of
Camphor has been found to decrease the rate of oxygen consumption by rat kidney mitochondria. The rate of oxygen consumption is nearly halved by the addition of 8 X 10(-3) M camphor. It is suggested that camphor may be of use in oxygenating tumours prior to radiotherapy.
Both sonochemical and classical methodologies have been employed to convert camphor, 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one, C₉H16C=O, into a number of derivatives including hydrazones, C₉H16C=N-NHAr 3, imines, C₉H16C=N-R 7, and the key intermediate nitroimine, C₉H16C=N-NO₂ 6. Reactions of
Consumption of camphor infusions is widely used as an aphrodisiac in preparation for sexual intercourse, to boost performance. There is dearth of information associating or relating its consumption to liver or lung inflammation. Therefore, we investigated the effect of various doses of camphor in an
Rhazya stricta is a medicinal plant that is widely used in Saudi folklore medicine for treatment of various diseases. R. stricta fruit powder was sequentially extracted with n-hexane, chloroform, ethyl acetate, and methanol using a Soxhlet extractor. The cytotoxic effects of
The comparative radiosensitizing effects of camphor and metronidazole on murine transplantable mammary adenocarcinoma are reported. Male C3H/Jax mice bearing transplanted mammary tumours were treated with camphor (0.5 microM/body wt) or metronidazole (0.5 microM/g body wt) 45 min before subjecting
In this study we found that the ultraviolet sunscreen component 3-(4-methylbenzylidine)camphor (4MBC) is uterotrophic in immature rats when administered by either subcutaneous injection or oral gavage. These data confirm earlier reports of uterotrophic activity for this agent when administered to
Background/aim: The aim of this study was to determine the specific component of Rosmarinus officinalis (RO) responsible for increased flap survival and how RO displays its efficacy. Materials and methods: Rectangular random-pattern flaps were elevated from the back of each rat. Group I was the
This study examines the chemical composition and in vitro anticancer activity of the essential oil from Ocimum basilicum Linn. (Lamiaceae), cultivated in the Western Ghats of South India. The chemical compositions of basil fresh leaves were identified by GC-MS: 11 components were identified. The
OBJECTIVE
To analyze the chemical composition of essential oil from Thymus citriodorus and its toxic effect on liver cancer cells.
METHODS
The essential oil from Thymus citriodorus leaves was extracted by steam distillation, and GC-MS was used for analyzing chemical composition. 35 components were
Antroquinonol is isolated from Antrodia camphorata, a camphor tree mushroom, and is a valuable traditional Chinese herbal medicine that exhibits pharmacological activities against several diseases, including cancer. This first-in-human phase I study of antroquinonol included patients with metastatic
The medicinal herb feverfew [Tanacetum parthenium (L.) Schultz-Bip.] has long been used as a folk remedy for the treatment of migraine and arthritis. Parthenolide, a sesquiterpene lactone, is considered to be the primary bioactive compound in feverfew having anti-migraine, anti-tumor, and
