A study led by researchers at the Germans Trias i Pujol Research Institute (IGTP) shows, in an experimental laboratory model, that delafloxacin inhibits the intracellular replication of Legionella more effectively than one of the current standard treatments. The findings provide new evidence of its potential therapeutic value and support the need for future clinical studies in patients with Legionnaires' disease.

Discovering effective drug combinations may now be easier thanks to a screening platform made public today by St. Jude Children’s Research Hospital scientists. Many diseases, including cancers, require combinations of drugs whose effects are more than the sum of their parts to create effective treatment regimens. However, the number of new drugs and potential combinations has exploded, making classical screening methods impractical.

A study from the University of Maryland, Baltimore County (UMBC), published in Nature Communications, reveals how enteroviruses - including pathogens that cause polio, encephalitis, myocarditis, and the common cold - initiate replication by hijacking host-cell machinery. Led by senior author Deepak Koirala, associate professor of chemistry and biochemistry, and recent Ph.D. graduate Naba Krishna Das, the research fills a knowledge gap on this critical step and could pave the way for a new class of antiviral drugs that are effective against multiple viruses.

From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.

In a new study, Northwestern University scientists uncovered the molecular trick behind PANX1’s versatility.

A new multi-site study led by researchers at CU Anschutz shows that people with cystic fibrosis (CF) who start the triple-drug therapy elexacaftor/tezacaftor/ivacaftor (ETI) can safely reduce many of their daily lung treatments while maintaining good health for years.

The study was published in the Journal of Cystic Fibrosis.

For the first time, MIT chemists have synthesized a fungal compound known as verticillin A, which was discovered more than 50 years ago and has shown potential as an anticancer agent.

The compound has a complex structure that made it more difficult to synthesize than related compounds, even though it differed by only a couple of atoms.

Researchers at The University of Texas MD Anderson Cancer Center have identified a specific protein, RASH3D19, that is responsible for activation of RAS signaling pathways involved in aggressive tumor growth and resistance to KRAS inhibitors in patients with KRAS-mutant cancers. Blocking RASH3D19 in combination with KRAS inhibitors improved outcomes in preclinical models, suggesting this combination as a potential therapeutic strategy for patients with KRAS-mutant cancers.
