From carnivorous plants to the medicine cabinet?
Date:2/18/2010

s is originally found in India but is also being reared in Tel Aviv University greenhouses.

Currently there is a need for additional broadly effective anti-fungal drugs. Even mildly severe forms of athlete's foot or other skin fungal infections lack effective treatments. The problem becomes more dire at hospitals, where thousands of Americans die each year from secondary fungal infections they acquire during their stay as patients.

Forging a "wild" pathway in drug discovery

The collaborating team has determined plant secondary metabolites that function as anti-fungal agents. "The pitcher of the carnivorous plant produces these compounds in a gland," says Prof. Zilberstein. Until now, no one has published or discussed the anti-fungal metabolites found in the trap liquid of this plant, she says.

"We're hoping that these metabolites are working together to keep fungus at bay. Our aim now is to get funding for pre-clinical tests of these compounds in an animal model, so we can investigate their effectiveness against the two very acute fungal pathogens found in hospitals worldwide," she says.

The idea that liquid from a plant pitcher could stave off infection has been documented in the folk literature of India, where people drink carnivorous plant pitcher juice as a general elixir. "There is a lot of room for developing compounds from nature into new drugs," says Prof. Zilberstein. "The one we are working on is not toxic to humans. Now we hope to show how this very natural product can be further developed as a means to overcome some basic problems in hospitals all over the world."
