ABC Transporter MsbA Inhibitors Discovered to Help Fight Against Gram-Negative Bacteria

ABC Transporter Inhibitor Klebsiella Treatment
Gram-negative bacterial pathogens pose grave dangers in clinical and environmental settings alike. They include foodborne disease pathogens such as E. coli 0157:H7, waterborne pathogens such as Vibrio cholera, vector-borne pathogens such as Yersinia pestis, and a disturbingly large number of Gram-negative pathogens that now display resistance to multiple antimicrobial agents.1 Resistant Gram-negative pathogens include some

Minding the Membrane: Powerful Approach to Interrogate Molecular Events in Ras-PI3K Interactions

It has been 30 years since the lipid signaling molecule phosphatidylinositol 3,4,5-trisphosphate (PIP3) was first identified¹, and its role as a key regulator of cell growth and survival was recognized in the earliest investigations into this molecule.² Class IA phosphoinositide 3-kinases (PI3Ks) generate PIP3. The inappropriate activation of this pathway has grave consequences in many

Transcreener Assay Helps Find New Approach to C. difficile

Clostridium difficile – One of the Deadliest Enemies in Hospitals There are half a million reasons to consider Clostridium difficile as “Enemy Number 1” for public health. That’s because the annual cases of C. difficile, or C diff, infection now top 500,000 per year in the U.S.—resulting in more than 29,000 deaths per year. Worse

Transcreener ADP Assay Aids in Discovery of RIPK2 Inhibitors for Autoinflammation

When the body responds to a bacterial pathogen, fragments of bacterial peptidoglycan alert a human host to the presence of a microbial invader. A receptor named NOD2 recognizes the peptidoglycans and sounds the alarm, initiating immune responses by causing the production of pro-inflammatory cytokines via NF-κB and MAP kinase pathways 1. In this manner, NOD2

Newly Patented Aurora A Kinase Inhibitor a Promising Contender for Cancer Treatment

Aurora A Kinase in Cancer Drug Development Aurora A Kinase, along with -B and -C, are members of a family of serine/threonine protein kinases that play critical roles in coordinating mitosis, including establishment of the mitotic spindle, centrosome duplication, centrosome separation as well as maturation, chromosomal alignment, spindle assembly checkpoint, and cytokinesis. The enzyme’s role

Using the Transcreener® GDP Assay to Discern the Truth about Dynamin Inhibitors

Imagine viewing the plasma membrane of a cell from an interior perspective, with a front-row seat to the process by which substances enter the cell. Over in one corner, the plasma membrane begins to bulge inward, forming a sphere stretching toward you with a droplet-shaped neck on the opposite side that remains connected to the

BellBrook Labs’ Transcreener ADP Assay Aids in the Fight Against Antibiotic Resistant Bacteria

RecA, a protein pivotal in bacteria’s ability to mutate and resist antibiotic treatment, is an attractive therapeutic target, however efforts to find small molecule drugs that block its function have been limited by the sensitivity of the assays used to detect its ATP hydrolysis (ATPase) activity. Recently researchers at The University of North Carolina at
