The prominent role of Ca2+ in cell physiology is mediated by a whole set of proteins involved in Ca2+-signal generation, deciphering and arrest. Among these intracellular proteins, calmodulin (CaM) known as a prototypical calcium sensor, serves as a ubiquitous carrier of the intracellular calcium signal in all eukaryotic cell types. CaM is assumed to be […]

We have developed a surface plasmon resonance (SPR)-based inhibition in solution assay (ISA) to search for inhibitors of the medium affinity (KD = 0.8 μM) interaction between an E6-derived peptide (E6peptide) immobilized on the sensor and a PDZ domain (MAGI-1 PDZ1) in the mobile phase. DZ domains are widespread protein-protein interaction modules that recognize the […]

Conventional antimicrobials are increasingly ineffective due to the emergence of multidrug-resistance among pathogenic microorganisms. The need to overcome these deficiencies has triggered exploration for novel and unconventional approaches to controlling microbial infections. Multidrug efflux systems (MES) have been a profound obstacle in the successful deployment of antimicrobials. The discovery of small molecule efflux system blockers […]

Drug ‘repurposing’, that is, using old drugs for new indications, has been proposed as a more efficient strategy for drug development than the current standard of beginning with novel agents. In this review, we explore the scope of drug repurposing in pediatric hematology oncology and in pediatrics in general. Drugs commonly used in children were […]
