Triketones active against antibiotic-resistant bacteria: Synthesis, structure–activity relationships, and mode of action
摘要:
A series of acylated phloroglucinols and triketones was synthesized and tested for activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecalis (VRE) and multi-drug-resistant Mycobacterium tuberculosis (MDR-TB). A tetra-methylated triketone with a C-12 side chain was the most active compound (MIC of around 1.0 mu g/ml against MRSA) and was shown to stimulate oxygen consumption by resting cell suspensions, suggesting that the primary target was the cytoplasmic membrane.

treatment of AD. Colupulone, a prenylated phloroglucinol isolated from Humulus lupulus, is known to activate pregnane-X-receptor (PXR), which is a nuclear receptor controlling P-gp expression. In the present work, we aimed to synthesize and identify analogs of colupulone that are potent P-gp inducer(s) with an ability to enhance Aβ transport across the BBB. A series of colupulone analogs were synthesized
