  Abstract

Pancreatic cancer is an exceptionally aggressive disease, the
treatment of which has largely been unsuccessful due to higher
resistance offered by pancreatic cancer cells to conventional
approaches such as surgery, radiation and/or chemotherapy. The
aberration of Ras oncoprotein has been linked to the induction of
multiple signaling pathways and to the resistance offered by
pancreatic cancer cells to the apoptosis. Therefore, there is a need
for development of new and effective chemotherapeutic agents which can
target multiple pathways to induce responsiveness of pancreatic cancer
cells to death signals. In this study, human pancreatic adenocarcinoma
cells AsPC-1 were used to investigate the effect of Lupeol on cell
growth and its effects on the modulation of multiple Ras-induced
signaling pathways. Lupeol caused a dose-dependent inhibition of cell
growth as assessed by MTT assay and induction of apoptosis as assessed
by flow cytometry, fluorescence microscopy and western blotting.
Lupeol treatment to cells was found to significantly reduce the
expression of Ras oncoprotein and modulate the protein expression of
various signaling molecules involved in PKC/ODC, PI3K/Akt and MAPKs
pathways along with a significant reduction in the activation of NFB
signaling pathway. Our data suggests that Lupeol can adopt a multi-
prong strategy to target multiple signaling pathways leading to
induction of apoptosis and inhibition of growth of pancreatic cancer
cells. Lupeol could be a potential agent against pancreatic cancer
however, further in-depth in vivo studies are warranted.

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 treated with lupeol; its
effect on growth, proliferation, and apoptosis were evaluated. Further
athymic nude mice bearing 451Lu cell-originated tumors were
administered with lupeol thrice a week, and its effect on tumor growth
and surrogate biomarkers was evaluated.

Results: Lupeol significantly decreased the viability of 451Lu and
WM35 melanoma cells but had only a marginal effect on normal human
melanocyte cells at similar doses. Lupeol treatment of 451Lu cells
caused (a) G1-S phase cell cycle arrest and apoptosis; (b) down-
regulation of Bcl2 and up-regulation of Bax; (c) activation of
caspase-3 and induction of poly(ADP)ribose polymerase cleavage; (d)
decreased expression of cyclin D1, cyclin D2, and cdk2; and (e)
increased expression of p21 protein. Next, lupeol significantly
reduced 451Lu tumor growth in athymic nude mice and modulated the
expression of proliferation markers, apoptotic markers, and cell cycle
regulatory molecules in tumor xenografts.

Conclusion: Our findings showed the anticancer efficacy of lupeol with
mechanistic rationale against metastatic human melanoma cells. We
suggest that lupeol, alone or as an adjuvant to current therapies,
could be useful for the management of human melanoma.

"Lupeol enhanced cisplatin anti-tumour activity  by 40-fold."

HK experts reveals lupeol in fruits helps combat cancer

www.chinaview.cn  2007-10-16 16:34:22      Print

   HONG KONG, Oct. 16 (Xinhua) -- A study found that a substance
called "lupeol" contained in fruits may help beat head and neck
cancer, announced the University of Hong Kong which made the result
public here Tuesday.

   The study, conducted by the university's Faculty of Medicine,
revealed that lupeol, a compound rich in fruits, selectively targeted
and killed cancer cells. Using a mouse animal model, lupeol
dramatically decreased tumor volume and suppressed local metastasis
while bearing minimal effect on surrounding tissue and other vital
organs like liver and kidney.

   Interestingly, lupeol was found to be more effective and more
potent than conventionally used chemotherapeutic drug, cisplatin, by
approximately three-fold in terms of tumor volume and degree of
metastasis suppression.

   Besides, when lupeol was used in combination with cisplatin, the
anti-tumour activity of the chemotherapeutic drug could be enhanced by
40-fold.

   The above research result was published in the international
scientific journal Cancer Research in September, 2007.

   Head and neck cancer includes cancers of the nose, oral cavity,
salivary gland, etc. In the year 2004, 2,087 new cases were diagnosed
in Hong Kong, with the number of new cases increasing steadily every
year.

   Human papilloma virus infection, alcohol and tobacco consumption
and low fruits and vegetables intake all contribute to the increased
risk of head and neck cancer development.

   The university was in the hope that the findings will also show
people that only a slight change in their everyday meal or a small
change in their choice of food intake may have an astounding impact on
cancer prevention and therapy.

Résumé / Abstract
Adult male Wistar rats were made arthritic by the subplantar injection
of complete Freund's adjuvant. Oral treatment with the triterpenes
lupeol, luepol palmitate, or lupeol linoleate (66 mg/kg BW every 2
days) from days 24 to 32 reduced synovial granulomatous growth
(proximal interphalangeal foot joints) and its invasion of the
synovial cavity and reduced the destruction of articular cartilage and
subchondral bone (lupeol linoleate > lupeol palmitate > lupeol). Rats
treated with the lupeol esters showed reduced periosteal bone erosion
with bone repair in the form of periosteal new bone formation.
Arthritic rat blood lymphocytes and serum levels of the joint
degradative product, hyaluronate, which increased by 73% and 51%,
respectively, were reduced by the triterpenes (lupeol linoleate >
lupeol palmitate > lupeol) with lupeol linoleate restoring them to
normal values. The antiarthritic effectiveness of lupeol was therefore
increased by esterification with the long-chain fatty acids.

"Birch bark"

Science: The glue that held the Roman empire together
06 March 1993

Tools
  When people in Roman Britain broke their clay pots, they glued them
back together with a tar made from birch bark, according to
archaeologists. The evidence comes from a ceramic jar found among
Roman artefacts unearthed at the West Cotton site in the Rounds area
of Northamptonshire.

The jar had been repaired with a black tarry adhesive. When scientists
at the Universities of Bradford and Liverpool analysed the tar, they
found that it contained betulin, lupeol, lupenone, allobetul-2-ene and
other pentacyclic triterpenoid (Archaeometry, vol 35, p 91). This
composition was similar to both fresh birch bark and a freshly made
tar from birch bark.

The researchers tried to make their own glue by drying fresh birch
bark at room temperature and then heating it to a high temperature in
a covered vessel. The result was a charred material sticky enough to
be an adhesive. The researchers claim that the pot repairers might
have made their glue in a similar way.

Archaeologists knew about the use of birch bark tar but this is the
first time that they have found it in ancient Britain. In mainland
Europe in Neolithic times - several thousand years before the Romans -
birch bark tar was also used as a chewing gum for cleansing teeth,
presumably because chewing released some of its constituent
compounds.

Further Research On Resveratrol Shows Promise For Treatment Of
Pancreatic Cancer
Main Category: Cancer / Oncology
Also Included In: Nutrition / Diet
Article Date: 14 Apr 2008 - 2:00 PDT

Baywood International, Inc. (OTCBB:BAYW) ("Company") announced that
resveratrol, the antioxidant found in grape skins and red wine, can
cripple the function of pancreatic cancer cells while sensitizing them
to chemotherapy, says new research. This study, published in March
2008 in Advances in Experimental Medicine and Biology, looked at the
way the antioxidant may aid pancreatic cancer treatment and how it
also contributes to the growing knowledge on the health benefits
arising from ingredients of red wine.

While disabling the function of the cancer cells by reaching and
reacting with the mitochondria (the cell's energy source), researchers
found that when they were pre-treated with resveratrol before being
irradiated, it resulted in a type of cell death called apoptosis. This
is an important goal of cancer therapy.

According to Paul Okunieff, chief of radiation oncology at the
University of Rochester Medical Centre, "Antioxidant research is very
active and very seductive right now [and] the challenge lies in
finding the right concentration and how it works inside the cell.
Resveratrol seems to have a therapeutic gain by making tumor cells
more sensitive to radiation and making normal tissue less sensitive."

Okunieff began studying resveratrol as a tumor sensitizer, which is
when the link to the mitochondria was uncovered. Researchers divided
pancreatic cancer cells into two groups: cells treated without
resveratrol then iodized, and ones treated with resveratrol at a
relatively high dose of 50mg per ml before being iodized. The amount
of resveratrol in red wine can vary between types of grapes and
growing seasons, and ranges can be as high as 30 mg per ml. But the
researchers said higher doses are expected to be safe as long as a
physician monitors the patient. The study found that resveratrol
reduced the function of proteins in the pancreatic cancer cell
membranes responsible for pumping chemotherapy out of the cell,
therefore making them more sensitive to the treatment. Additionally,
the antioxidant triggered the production of reactive oxygen species
(ROS), causing apoptosis, and depolarized the mitochondrial membranes,
indicating a decrease in the cell's potential to function. The
researchers said the discovery is important because the mitochondria
contains its own DNA and can continuously supply the cell with energy
when functioning fully. Stopping the energy flow can therefore help
stop cancer.

Okunieff further stated that, "While additional studies are needed,
this research indicated that resveratrol has a promising future as
part of the treatment for cancer."

The Company's wholly-owned subsidiary, Nutritional Specialties, Inc./
dba LifeTime(R), launched Resveratrol Life Tonic(tm) in liquid form for
enhanced bioavailability. The product's powerful antioxidant
properties include 300 mg of resveratrol extract in each one ounce
serving, which is equivalent to 1,300 glasses of red wine.(a)

Abstract

Direct detection of saponins in medicinal plants using Fourier
Transform Infrared (FTIR) spectroscopy is reported in this paper.
Crude dry plant powders were mixed with potassium bromide (KBr) powder
and compressed to a thin pellet for infrared examination. FTIR spectra
of the test samples showed -OH, -C=O, C-H, and C=C absorptions
characteristic of oleanane triterpenoid saponins. The C-O-C
absorptions indicated glycoside linkages to the sapogenins.
Phytochemical analysis confirmed the presence of saponins in the
tested specimens. Entada leptostachya    was used as a reference
sample. Dry plant powder was extracted sequentially with hexane,
dichloromethane, ethyl acetate and methanol. FTIR spectra of the
reference sample powder and its organic solvent extracts showed
characteristic saponin absorption peaks. These results indicated that
direct detection of saponins in medicinal plants was possible by
infrared analysis. Lengthy exhaustive chemical analyses necessary for
detection of saponins could be avoided.

70950  Celastrol
(CAS 34157-83-0)

A variety of natural products from plant sources, particularly
flavonoids, have long been observed to have antioxidant activity with
potential benefits for human health.
Antioxidant triterpenes are less common.
Celastrol is a triterpenoid antioxidant compound isolated from the
Chinese Thunder of God vine (T. wilfordii).
In an isolated rat liver assay of lipid peroxidation, celastrol had an
IC50 value of 7 µM, equivalent to about 15 times the antioxidant
potency of α-tocopherol.

Sooo .. in theory .. the use of effective herbicides 'may' not be all
that good due to the fact these triterpenes seem to be created BECAUSE
of the insult FROM a pathogen .. they are the antibiotics of the
plant .. ?

Sooo .. again theoretically one could assault one's broccoli in the
garden with certain pathogens and it just might raise MORE than the
sulphur content of the broccoli .. ?

If the broccoli has the ability to create the triterpenes and not JUST
sulphur.

Somewhat like when yeast creates substances bacteriocidal
properties .. WHEN presented with a pathogen.

Sulphur is created as the plant's antibiotic.

New study shows Dermytol produces pronounced decrease in malignant
melanoma tumor volume

A new study presented at the Experimental Biology Annual Meeting, held
April 5-9, 2008, in San Diego, California, USA showed that a
proprietary blend extracted from canola, Dermytol™, produces a
pronounced reduction of malignant melanoma cell growth. Dermytol™, a
proprietary compound developed by KGK Synergize Inc., a biotechnology
company in Ontario Canada, is designed to protect skin cells from
damage that may lead to skin cancer.

Mal Evans, scientific director of KGK Synergize Inc., said, "Skin
cancer rates have been rising, and we are likely to see that continue
as the population ages. The National Cancer Institute (NCI) estimates
that more than 62,000 Americans will be diagnosed with melanoma and
one million Americans will be diagnosed with nonmelanoma skin cancer
this year. NCI expects more than 8,000 deaths from melanoma and less
than 1,000 deaths from nonmelanoma cancers this year.

"Dermytol has the potential to be used in anti-aging and sun-
protection products to reduce damage to skin. Results of preclinical
trials in animals have been promising leading to human trials now
running in both Canada and the United States."

In the most recent study, male mice were fed either a Dermytol-canola
oil mixture or just canola oil. In a separate part of the study,
researchers applied either a Dermytol cream or a placebo cream onto
the shaved skin of a different group of mice. After seven days of
treatment, all of the mice were injected with malignant melanoma tumor
cells. Dermytol or placebo treatments continued for 25 days.

The mice in both Dermytol groups benefited from their treatments.
Compared wth the controls, the orally treated mice showed an average
decrease in tumor size by about 45%. The mice receiving the topical
treatment benefited even more with a 61% decrease in tumor volume.

In this study and previous preclinical studies, Dermytol produced no
adverse effects.

In a laboratory cell culture study, Dermytol inhibited the
proliferation of human cancer cells.

In another study, dietary supplementation with Dermytol moderately
delayed the onset of skin tumors and significantly reduced tumor
growth rate in mice treated to induce nonmelanoma skin cancers.

A trial involving 45 subjects with actinic keratoses--precancerous
skin lesions--is under way. "The current treatment for actinic
keratoses is removal by freezing, which can be painful, or the
application of a cream that causes inflammation and blistering of the
skin," said Evans. "We expect Dermytol to be a welcome option."

Changes in anatomy and terpene chemistry in roots of Douglas-fir
seedlings following treatment with methyl jasmonate.

[My paper] Dezene P W Huber, Ryan N Philippe, Lufiani L Madilao, Rona
N Sturrock, Jörg Bohlmann
Michael Smith Laboratories and Departments of Botany and Forest
Sciences, University of British Columbia, 237 - 6174 University Blvd.,
Vancouver, BC V6T 1Z4, Canada.
Replicated trials were conducted on two full-sibling families of
Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings. In
response to the application of a 0.01% solution of methyl jasmonate
(MeJA) to the soil of potted seedlings, numerous anatomical and
chemical changes were observed in the roots, stem and foliage. These
changes were, for the most part, similar for both sib groups. Methyl
jasmonate induced traumatic resin duct formation in roots and stems.
Chemical differences between MeJA-treated and control seedlings were
mainly limited to the roots and stem, though some changes also
occurred in the foliage. A total of 35 terpenoids were observed in the
P. menziesii seedlings. In response to MeJA treatment, several of the
22 detected monoterpenoids (linalool, bornyl acetate, camphene,
myrcene, alpha- and beta-pinene, tricyclene and beta-phellandrene)
increased significantly in roots and stems, whereas (E)-beta-ocimene
decreased significantly in the foliage. Four of the five detected
sesquiterpenoids (alpha-humulene, germacrene D, longifolene and (E)-
caryophyllene) increased significantly following MeJA application,
mainly in the root and stem. Four of the eight detected diterpenoids
(abietate, levopimarate, palustrate and sandaracopimarate) increased
in response to MeJA treatment, but only in root and stem tissue. This
study provides the first description of the effects of MeJA applied to
roots through the soil on the anatomy and terpene chemistry of a
gymnosperm. This comprehensive inventory of terpenoids in P.
menziesii, with and without MeJA treatment, may facilitate
identification of terpenoid-related resistance traits. Potential
practical applications of MeJA treatment of conifer roots as a pest
management strategy are discussed.
