The artificial enzymes would be more stable than their natural countertparts and also have other advantages.

The Columbia researchers said their artificial enzyme should destroy most cocaine in the bloodstream before it reaches the brain.

One of the pioneers in artificial enzyme research is chemist Ronald Breslow.

Synthetic molecules called artificial enzymes also display enzyme-like catalysis.

It seemed to be an oxygen activator - an artificial enzyme used to promote the effect of oxygen in the Monster system.

An artificial enzyme is a synthetic, organic molecule prepared to recreate the active site of an enzyme.

Since the artificial enzymes need to bind molecules, they are made based on a host-molecule such as a cyclodextrin, crown ethers or calixarene etc.

Mikael Bols (born July 28, 1961) is a synthetic organic chemist who is mainly known for his work on carbohydrates and artificial enzymes.

For more on non-protein molecular tools, see "Artificial Enzymes," by Ronald Breslow (Science, Vol.

New approaches based on amino acids or peptides as characteristic molecular moieties have led to a significant expansion of the field of artificial enzymes or enzyme mimics.

Myriad of Potential Uses For example, the work has raised the possibility of creating totally artificial enzymes that might have advantages over the natural substances that control the destinies of cells.

A number of artificial enzymes have been reported catalysing various reactions with rate increases up to 10; this is nevertheless substantially lower than natural enzymes that typically causes rate increases above 10.

Dr. Lehn's Nobel-winning work, in which he took the discoveries of so-called crown ethers and made them into artificial enzymes, was only one of a number of his outstanding results, chemists said.

Scientists say they have developed an artificial enzyme that reduces the addictive effect of cocaine in test tube studies, a development some experts say could eventually lead to a new weapon to treat cocaine abuse.

The discovery of isofagomine and related glycosidase inhibitors, the discovery of stereoelectronic substituent effects and superarmed glycosyl donors, the creation of artificial enzymes that cause large rate increases., and writing the book carbohydrate building blocks about using carbohydrates as a chirality source in synthesis.
