They stop inflammation by blocking an enzyme called Cox-2 without also hitting a related enzyme called Cox-1.
Moreover, by focusing on one type of drug--the enzyme--Price thinks BioMarin can pump out one drug a year.
Like Vioxx, it is an arthritis drug that works by inhibiting the enzyme known as COX-2, without knocking out another enzyme called COX-1.
It is in a race with several companies that are taking aim at a novel target, a protein-chewing enzyme called DPP-4 (dipeptidylpeptidase 4) which plays a role in disrupting the production of insulin.
This prostaglandin-producing enzyme is called cyclo-oxygenase (COX).
Pigs or indeed potatoes can produce human proteins for medical use (though none has yet received authorisation), foot-and-mouth vaccine can come from alfalfa, genes from enzyme-making bacteria can do the same job in tobacco, and useful new enzymes can be found and put into old bacteria.
In 1998 Kandel's team injected aging mice with a failed antidepressant called Rolipram, which prevents the breakdown of cyclic-AMP by blocking an enzyme called phosphodiesterase-4.
Cox-2 inhibitors, developed with much hype in the mid-1990s, block an enzyme called cyclooxygenase-2, in so doing shutting off a wide-reaching cascade of biochemical signals that take the form of fats called prostaglandins.
But when the protein was attached to the mRNA for the Cox-2 enzyme, cancer cells could no longer make Cox-2, and they died, suggesting it plays a key role in tumour cell survival or death.
Previous research found that enzyme-modified milk could stop Streptococcus mutans from binding to tooth enamel.
Three other companies that Jenner and Markowitz own are working on a different class of enzyme-attacking drugs called polymerase inhibitors.
Shire research is aimed at developing an enzyme-replacement therapy, while the planned research at Nationwide Children's will focus on potential gene therapy.
Dr Rondelez has used his enzyme-based approach to build a molecular oscillator, which should be a useful addition to the molecular-computing toolbox.
Thus far the most promising new class of such enzyme-attacking drugs looks to be protease inhibitors, best known for combating the progress of HIV infections in the body.
It's when her acolytes start stalking her, desperate to have their skin healed by her soothing touch and her secret enzyme-and-zinc potion, which leaves skin baby-soft and plump.
The researchers think the high death rate from sepsis and shock may have its origin in the digestive system and that using enzyme-blocking drugs may help reduce the harmful effects.
The rats were also quicker to return to their everyday behaviours than the ones that did not get the enzyme-blocking drugs, shows the study, published in the journal Science Translational Medicine.
So the last step on the winding road was the creation of a bacterial strain without any restriction-enzyme genes, and thus without restriction enzymes, so that the team could have a purified reaction vessel in which the new genome could do its thing.
Inhibitors work by curbing the action of the angiotensin-converting enzyme (ACE), which governs the release of angiotensin-2.
They are often used alongside angiotensin-converting enzyme inhibitors, such as Accupril, Zestril and Prinivil.
Researchers noted that prolonged sitting can cause a 90 percent reduction in a heart-healthy enzyme, lipoprotein lipase, which could explain the results.
FORBES: Four hours on your computer doubles risk of heart disease
In 1999 he published results in the Proceedings of the National Academy of Sciences that pointed out how blocking the enzyme Cox-2 prevented the production of prostacyclin.
Ajinomoto switched to a soy-based enzyme, but not soon enough: its shares plummeted, and it had to recall thousands of tonnes of its products from Indonesian shelves.
ECONOMIST: How to cope with divine intrusions on Mammon��s turf
Merck says that its studies have not turned up this side effect, and that Januvia was designed to bind only to the DPP-4 enzyme, reducing the chances of these side effects.
Scientists aren't exactly sure why the Cox-2s could fight cancer, although it appears much of their action lies in the inhibition of the Cox-2 enzyme, which is also involved in swelling.
Adding a sweet substance solves the problem of liver and kidney toxicity, allowing him to deliver safely a far more potent dose of relief that he suspects may target the COX-3 enzyme.
Scientists had no hard evidence on how it works, but the recent discovery of the COX-3 enzyme by Daniel Simmons, a scientist at Brigham Young University, might hasten the arrival of the next Tylenol.
To be specific, Merck (MRK) will test a beta-amyloid precursor protein site-cleaving enzyme, or BACE, inhibitor, which the drugmaker notes is the first drug with this type of mechanism to advance to this stage of clinical research.
In one study of 1, 740 men with high cholesterol, Scottish researchers found that men with high levels of the Lp-PLA2 enzyme had twice the risk of heart attacks, an effect that was statistically independent of their cholesterol levels.
Once it's clear that broken heart syndrome is the cause of your symptoms, your doctor will likely prescribe heart medications for you to take while you're in the hospital, such as angiotensin-converting enzyme (ACE) inhibitors, beta blockers or diuretics.
