Researchers discovered that certain antibodies employ unusual tactics to block bacterial adhesion, including creating molecular wedges and conformational traps. These mechanisms could lead to the development of immune therapies targeting glycan-binding cell-attachment proteins produced by bacteria causing urinary tract infections.
New research suggests that ocean turbulence and horizontal stirring will dramatically increase in the Arctic and Southern Oceans due to human-induced Global Warming. The study uses ultra-high-resolution simulations to investigate how mesoscale horizontal stirring (MHS) responds to warming, revealing a pronounced future intensification ...
Scientists from the University of Bath have identified two new families of chemical compounds that inhibit alpha-methylacyl-CoA racemase (MCR) in Mycobacterium tuberculosis, a key enzyme for TB survival. This breakthrough could lead to new treatments for TB and potentially other diseases like prostate cancer.
Scientists have discovered a novel way to block an enzyme involved in regulating blood pressure, called ACE. Ciprofloxacin binds selectively to a different site, blocking angiotensin I but not inhibiting the enzyme's other functions.
Researchers have identified a potential compound that enhances naloxone's effectiveness in reversing opioid overdoses by making it more potent and longer-lasting. The compound, dubbed compound 368, was found to improve naloxone's ability to counteract opioid overdoses in mice and enable reversal at lower doses.
Researchers employ DFT and NEST analysis to investigate pyrrolidinyl gold(I) complexes, revealing enhanced understanding of electronic and steric effects. The findings facilitate the design of novel chiral ligands for enantioselective reactions.
Researchers identified four partially hidden binding pockets on the SARS-CoV-2 virus's Nsp1 protein that could be targeted with drugs. These pockets are found to halt virus replication and prevent immune system shut-down, providing a promising lead for future coronavirus treatments.
Researchers at Osaka University have discovered the spatial characteristics of an efflux pump that helps bacteria resist antibiotics. By analyzing a specific inhibitor's binding site, they found bulky mutations can prevent the inhibitor from working, offering hope for developing new countermeasures to combat antibiotic resistance.
The Paul Scherrer Institute and Italian Institute of Technology have developed a novel substance called Todalam that disables tubulin, a protein essential for cell division. In cell cultures, Todalam kills cells, making it a promising starting point for developing an anti-cancer drug.
Researchers have identified the activation mechanism of SHP2, a key player in cancer development. The study reveals that flexible beta sheets, not previously thought to be crucial, open in the presence of a peptide, triggering SHP2 activation.
Researchers developed a micelle-type nano-container that can be switched between assembled and disassembled states via light irradiation. The system demonstrated the release of guest molecules in water, showcasing its potential for non-invasive drug delivery.
Researchers have designed and synthesized a molecular structure featuring a helical binding pocket that selectively captures xylobiose, a disaccharide class of carbohydrates. The molecule's synthesis and characterization were published in Angewandte Chemie, with the journal editors rating it as 'very important.'
Chemists at Max Planck Institute develop enzyme that converts diverse molecules enantioselectively, producing desired biological activity. By modifying amino acids distant from the reaction site, they create an optimized catalyst with improved efficiency and selectivity.
Researchers at Stanford University School of Medicine identified a new method for reducing drug side effects by focusing on neglected areas of cell-surface proteins. By analyzing the shape changes in response to drugs, they discovered potential targets for more selective and effective medications.
