Anti-Cancer Flower Power

August 26, 2008

Could a substance from the jasmine flower hold the key to an effective new therapy to treat cancer?

Prof. Eliezer Flescher of The Sackler Faculty of Medicine, Tel Aviv University thinks so. He and his colleagues have developed an anti-cancer drug based on a decade of research into the commercial applications of the compound Jasmonate, a synthetic compound derived from the flower itself. Prof. Flescher began to research the compound about a decade ago, and with his recent development of the drug, his studies have now begun to bear meaningful fruit.




"Acetylsalicylic acid (aspirin) is based on a plant stress hormone," says Prof. Flescher. "I asked myself, 'Could there be other plant stress hormones that have clinical efficacy?' While various studies have suggested that aspirin can prevent cancer, especially colon cancer, I realized that there could be a chance to find a potent plant hormone that could fight cancer even better. I pinpointed jasmonate."

A Natural Leap to the Drugstore Shelf

Both blood cancers and solid tumors seem to be responsive to the jasmonate compound, known also as methyl jasmonate. Prof. Flescher refers to it as the "jasmonate scaffold," a basis for developing a series of chemical derivatives. In terms of bioavailability and safety, early first-in-man studies have proven successful, and Prof. Flescher is hopeful that an anti-cancer drug based on jasmonate could be on the shelf in America within four years through the activity of Sepal-Pharma which licensed his research from Ramot, the technology transfer arm of Tel Aviv University.

Normally drug development takes much longer. "The jasmonate compound is used widely in agriculture and in cosmetics," says Prof. Flescher. "Proven to be non-toxic, it has the same regulatory status as table salt. That and the fact we are working on a natural chemical gives us a good starting point for launching a new drug."

Optimistic Responses from Peer Researchers

Other research groups are taking notice. Since Prof. Flescher started publishing papers on jasmonate (most recently in the academic journal Oncogene), six new research groups around the world have initiated research on the subject.

Peer commentary in Oncogene is positive about Prof. Flescher's promising research. "Methyl jasmonate," says the commentary, "has already been shown to have selective anticancer activity in preclinical studies, and this finding may stimulate the development of a novel class of small anticancer compounds."

Prof. Flescher's research is the foundation of a promising new biotech company, Sepal-Pharma, where Prof. Flescher serves on the scientific advisory board. Sepal-Pharma is developing new compounds based on the Jasmonate Scaffold. Sepal-Pharma has also been actively funding research done at Prof. Flescher's lab.

Understanding natural crop defenses
Ever since insects developed a taste for vegetation, plants have faced the same dilemma: use limited resources to out-compete their neighbors for light to grow, or, invest directly in defense against hungry insects.

The bonsai effect: Wounded plants make jasmonates, inhibiting cell division, stunting growth
It is well known that plants growing under unfavourable conditions are generally smaller than those growing in stress-free conditions: indeed it is estimated that in the US, abiotic stress reduces the yield of agricultural crops by an average of 22%.

Biochemists manipulate fruit flavor enzymes
Would you like a lemony watermelon? How about a strawberry-flavored banana? Biochemists at The University of Texas Medical School at Houston say the day may be coming when scientists will be able to fine tune enzymes responsible for flavors in fruits and vegetables. In addition, it could lead to environmentally-friendly pest control.

New crop of technology reveals plant health
Scientists have developed a system that picks up the subtle cues of plant communication helping plant growers to monitor the crop's state of health and will result in optimal environmentally-friendly growing conditions.

Crossing paths in plants
On Monday 31 March ecologists will meet with molecular biologists at the University of Southampton for the most novel and broad-ranging scientific session of its kind. They will present findings in Session C5/P3 which show that the biochemical pathways which influence a plant's response to stimuli such as attack, disease or other stresses are not mutually exclusive as previously thought. For example, up until recently the two separate signalling pathways in plants which respond independently to disease (caused by microorganisms and pathogens) and to wounding (by herbivores) were believed to be completely separate. Now biologists know that these pathways talk to each other in a process known

Jasmonate: Webster's Timeline History, 1990 - 2007
by Icon Group International (Author)

Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on "Jasmonate," including when used in literature (e.g. all authors that might have Jasmonate in their name). As such, this book represents the largest compilation of timeline events associated with Jasmonate when it is used in proper noun form. Webster's timelines cover bibliographic citations, patented inventions, as well as non-conventional and alternative meanings which capture ambiguities in usage. These furthermore cover all parts of speech (possessive, institutional usage, geographic usage) and contexts, including pop culture, the arts, social sciences...

Description:
We have presented changes in the photosynthetic apparatus activity of Arabidopsis thaliana plants occurring within 15-144h of 100@mM Cu or Cd action with regard to jasmonate (JA) as well as expression of the oxidative stress and non-enzymic defense mechanisms. The inhibitory effect of both heavy metals related to developing dissipative processes and lipid peroxide formation was expressed in dark-adapted state after the longest time as a decrease in potential quantum yield of PSII. In dark- and light-adapted state the...
