Tryptoline-based benzothiazoles re-sensitize MRSA to β-lactam antibiotics
摘要:
Resistance-modifying agents (RMAs) offer a promising solution to combat bacterial antibiotic resistance. Here we report the discovery and structure-activity relationships of a new class of RMAs with a novel tryptoline-based benzothiazole scaffold. Our most potent compound in this series (4ad) re-sensitizes multiple MRSA strains to cephalosporins at low concentrations (2 mu g/mL) and has low mammalian cytotoxicity with a half growth inhibitory concentration (GI(50)) > 100 mu g/mL in human cervical carcinoma (HeLa) cells. In addition, the same core scaffold with different substitutions also gives good antibacterial activity against MRSA.
The present disclosure relates to 1- or 2-(4-(aryloxy)-phenyl)ethylamino-, oxy- or sulfanyl)pteridines and 1- or 2-(4-(heteroaryloxy)-phenyl)ethylamino-, oxy- or sulfanyl)pteridines and their use as agrochemicals and animal health products.
