New method developed to synthesise a set of potential glycosidase inhibitors

In many biological and pathological processes, glycosidase enzymes attack glycosidic bonds in carbohydrates, glycoproteins, and glycolipids. The ability to modify or block these processes by specific glycosidase inhibitors forms the basis for their potential use in the treatment of viral infections, cancer, and genetic disorders.

Synthetic drugs treat Crohn's disease in mice

A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists managed to trick the immune systems of mice into targeting one of the body's players in autoimmune processes, an enzyme known as MMP9.

Researchers develop CAD-type tools to engineer RNA control systems

The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or "RNA devices" for controlling genetic expression in microbes.

New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

TU Darmstadt chemists develop new method to diagnose Alzheimer's

Chemists at the Technische Universität Darmstadt have developed a new method for diagnosing Alzheimer's disease. The method involves making protein deposits on mucous nasal membranes that are detectable years before the disease erupts visible.

Scientists achieve major step toward goal of producing synthetic Taxol

Taxanes are a family of compounds that includes one of the most important cancer drugs ever discovered, Taxol, among other cancer treatments. But the difficulty producing these complex molecules in the lab has hampered or blocked exploration of the family for further drug leads. Now, a group of Scripps Research Institute scientists has successfully achieved a major step toward the goal of synthetically producing Taxol and other complex taxanes on a quest to harness chemical reactions that could enable research on previously unavailable potential drugs.

Chemical biology researchers to meet at Scientific Oktoberfest in München

The "Scientific Oktoberfest" will be this year's meeting point for some of the internationally most distinguished researchers in the field of Chemical Biology. The so-called "CIPSM Fest of Chemical Biology" will be held from the 15th to the 16th of September in the Department of Chemistry of the Ludwig-Maximilians-Universität (LMU) München.

Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

DNA sequencing pioneer, two pharmaceutical researchers recognized as ACS 'Heroes of Chemistry'

Two scientists developed a new drug that helped pioneer the era of "personalized medicine" for cancer patients, an approach in which one-size-fits-all drugs yield to medicines customized to the genetic endowment of individual patients. Another scientist invented today's predominant technology for genetic sequencing, deciphering the genetic blueprint in the DNA that makes up the genes of living things.

Targeted therapies that attack stem cell-like cancer cells can prevent spread of prostate cancer

A successful interdisciplinary project is underway between two research groups, in which senior researcher Rebecka Hellsten and Professor Anders Bjartell at the Faculty of Medicine's division for Urological Cancer Research, Sk-ne University Hospital in Malm-, and Professor Olov Sterner and Assistant Professor Martin Johansson at the Lund University division of Organic Chemistry recently published their latest research findings in the scientific online journal PLoS ONE.

Researchers to develop new prostate cancer therapy

Prostate cancer that has become resistant to hormone treatment and that does not respond to radiation or chemotherapy requires new methods of treatment. By attacking stem cell-like cells in prostate cancer, researchers at Lund University are working on a project to develop a new treatment option.

New nanotechnology-based cancer treatment might improve chemotherapy

Researchers of the University of Granada and Edinburgh have developed a new therapy for cancer based on nanotechnology that might improve significantly chemotherapy, as it has not cause side effects.

OSU chemist developing solution to nerve agent exposure

Scientists are working to develop a new drug that will regenerate a critical enzyme in the human body that “ages” after a person is exposed to deadly chemical warfare agents.

Tocopherol derivatives as new dioxin receptor antagonists

When reactive oxygen species (ROS) hit the body, vitamin E helps to prevent damage to tissues and cells by acting as an antioxidant. The health benefits of vitamin E are numerous, and in fact, studies have found that people with higher levels of vitamin E in their system have a lower risk of heart disease and certain forms of cancer. A team led by Thomas Rosenau from the University of Natural Resources and Life Sciences in Vienna (Austria) now describe their synthesis of a series of modified vitamin E derivatives that show promise as dioxin receptor antagonists in the European Journal of Organic Chemistry.

Biochemist receives STAC grant to find treatment for C. albicans infection in premature infants

A $200,000 grant from the Rhode Island Science and Technology Advisory Council is helping a Bryant University biochemist find a treatment for a fungal infection that is often lethal to premature infants.

Scientists produce tiny molecular 'binder' that may help develop more efficient drugs

Developing new drugs is a highly costly and time-consuming process. Of 20 candidates, 19 are normally rejected because they don't work or have unwanted side effects. Now a research team led by Professor Lars Baltzer at Uppsala University has produced a tiny molecular "binder" that has the potential to change this landscape radically.
