Scientists design drug-like molecules to block early stage influenza infection

Currently available flu medications only target the virus after it has already established an infection, but what if a drug could prevent infection in the first place? Now, scientists at Scripps Research and the Albert Einstein College of Medicine have designed drug-like molecules to do just that, by thwarting the first stage of influenza infection. … Read more

Scientists unravel how plants decide to grow or make oil

Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living things—and potentially how to change its effects. Biochemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and colleagues at DOE’s Pacific Northwest National Laboratory (PNNL) have published a … Read more

Genetics of Cancer: Causes and Treatments

Cancer is a complex group of diseases characterized by uncontrolled cell growth and proliferation. It can affect virtually any part of the body and is caused by a combination of genetic, environmental, and lifestyle factors. The genetics of cancer play a crucial role in understanding its causes, development, progression, and potential treatments. Genetic Basis of … Read more

Mac-1 inhibitor compound shows promise in blocking SARS-CoV-2 replication in cell cultures

Research appearing in the Journal of Medicinal Chemistry shows for the first time SARS-CoV-2, the virus responsible for COVID-19, can be inhibited from replicating in living cell cultures using a compound that targets “Mac-1,” a protein key to defending SARS-CoV-2 against the human immune response. University of Kansas researchers in the lab of Anthony Fehr, associate professor … Read more

Cryo-EM structures elucidate primer synthesis mechanism in human DNA polymerase α-primase

Brandt Eichman and Walter Chazin, professors of biochemistry, have worked together to provide a better understanding of how exactly DNA replication is initiated in eukaryotes. Using Vanderbilt’s state-of-the-art instrumentation in the Center for Structural Biology’s Cryo-Electron Microscopy Facility, Eichman, Chazin, and their colleagues provided detailed visualizations of a multi-functional protein in action, which sheds light … Read more

Covalent inhibitor platform designed for targeting helicases in cancers and viral infections

Helicases are enzymes that unwind DNA and RNA. They’re central to cellular life, implicated in a number of cancers and infections—and, alas, extraordinarily difficult to target with drugs. Now, new research provides a powerful platform for designing covalent inhibitors tailored to target helicases. The paper, published in the Journal of the American Chemical Society, describes how researchers used … Read more

Retinoic acid identified as key regulator of stem cell lineage plasticity in skin

When a child falls off her bike and scrapes her knee, skin stem cells rush to the rescue, growing new epidermis to cover the wound. But only some of the stem cells that will ultimately patch her up are normally dedicated to replenishing the epidermis that protects her body. Others are former hair follicle stem … Read more

Researchers develop novel technique for precise protein modification using electricity

Boston College researchers used a mild charge of electricity to precisely modify proteins, a new tool that can be used to develop novel biotherapeutics and protein-based research tools, the team reported recently in the journal Nature Chemistry. The team, led by BC professors of chemistry Abhishek Chatterjee and Eranthie Weerapana, developed and optimized a novel … Read more

Chemists achieve breakthrough in synthesizing anticancer molecules from marine invertebrates

Nearly 30 years ago, scientists discovered a unique class of anticancer molecules in a family of bryozoans, a phylum of marine invertebrates found in tropical waters. The chemical structures of these molecules, which consist of a dense, highly complex knot of oxidized rings and nitrogen atoms, has attracted the interest of organic chemists worldwide, who … Read more
