New research is allowing biochemists to understand a key hierarchy of protein interactions that occurs in DNA

"All cancers are marked by some form of DNA replication gone awry, so a basic understanding of DNA replication is of paramount importance to those designing cancer-fighting drugs,"

Scientists have determined the crystal structure of a protein kinase C (PKC) isozyme

This structure should prove extremely useful in the rational design of small molecule inhibitors of PKCÈ, which has been implicated in T-cell mediated disease processes including inflammation and autoimmunity.

High-resolution images reveal the molecular rearrangements that rotavirus uses to break into cells

High-resolution images constructed by researchers at Children's Hospital Boston and Harvard Medical School reveal the molecular rearrangements that rotavirus – the most common cause of severe, dehydrating diarrhea and vomiting in children worldwide – uses to break into cells.

Antibodies produced by shark immune systems could be used to detect human pathogens

A recent discovery shows that antibodies produced by shark immune systems could be used to detect a range of human pathogens some of which have the potential to be used as biological warfare agents.

Large-scale computer simulations help understand SARS

A Mayo Clinic researcher is the first to develop a series of three-dimensional (3D) models of an enzyme responsible for the replication of the deadly SARS (Severe Acute Respiratory syndrome) virus.

New compound that is designed to overcome Gleevec resistance

One of the truly spectacular success stories in modern oncology is the development and implementation of Gleevec, a drug that virtually halts the progress of chronic myeloid leukemia. Yet for some patients who harbor particularly stubborn genetic mutations, Gleevec fails miserably.

Relatively difficult for the AIDS virus to develop resistance to the drug, tenofovir, or the DAPY (diarylpyrimidine) family of compounds

HIV is a moving target, unpredictably changing direction to elude anti-AIDS drugs, but researchers at Rutgers are clearly on the track of solutions to combat HIV drug resistance.

Paclitaxel analog kills more cancer cells than natural product

Paclitaxel, a natural compound from yew trees, is the world's best-selling anticancer drug. Several analogs are in clinical trial, with others in preclinical development. One problem that paclitaxel and all its analogs share, however, is that they are all highly complex compounds, and cannot be prepared synthetically in a commercially viable way.

Class of molecules that could lead to treatments for a wide range of diseases, including cancer, arthritis, and heart disease

By making use of model compounds in drug design, chemists at the University of California, San Diego identified a class of molecules that could lead to treatments for a wide range of diseases, including cancer, arthritis, and heart disease.

Scientists reveal the crystal structure of the first described enzymatic RNA

Scientists in the department of molecular biophysics and biochemistry at Yale revealed the crystal structure of the first described enzymatic RNA - what it looks like and how it reacts - in the journal Nature.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.
