Amphiphilic molecules linked by an aromatic nucleus were developed that showed high selectivity toward bacteria over mammalian cells, and lowdrugresistance. A promising compound 4g exhibited strong bactericidal activity against a panel of sensitive and resistant bacteria, low toxicity, the ability to reduce cell viability in biofilms, stability in mammalian fluids, rapid killing of pathogens, and

A previous phenotypic screen by GSK identified 2-(quinolin-4-yloxy)acetamides as potent growth inhibitors of Mycobacterium tuberculosis (Mtb). We report the results of a preliminary structure-activity relationship (SAR) study of the compound class which has yielded more potent inhibitors. An Mtb cytochrome bd oxidase deletion mutant (cydKO) was found to be hypersensitive to most members of the compound

The invention relates to a derivative of a FGF21 protein having a cysteine residue at a position corresponding to position 167, 169, 170, 171, 172, 173, 174, 175 and in particular position 180 or position 181 of mature human FGF21 and derivatives thereof having a side chain attached to this cysteine. The FGF21 derivatives of the invention display high potency towards the FGF receptors. The invention also relates to pharmaceutical compositions comprising such FGF21 derivatives and pharmaceutically acceptable excipients, as well as the medical use of the FGF21 derivatives.
Development of Membrane-Active Honokiol/Magnolol Amphiphiles as Potent Antibacterial Agents against Methicillin-Resistant <i>Staphylococcus aureus</i> (MRSA)
of novel honokiol/magnolol amphiphiles were prepared by mimicking the chemical structures and antibacterial properties of cationic antimicrobial peptides. Among them, compound 5i showed excellent antibacterial activity against Gram-positive bacteria and clinical MRSA isolates (minimum inhibitory concentrations (MICs) = 0.5–2 μg/mL) with lowhemolytic and cytotoxic activities and high membrane selectivity
