The 2-(1,2-dihydro-3-oxo-3H-pyrazol-2-yl)benzothiazole scaffold was selected as a central core structure for the discovery of novel antibacterial compounds. A systematic variation of the substituents on the oxo-pyrazole moiety, as well as on the benzo moiety, led to the creation of a small and focused library of benzothiazoles that was subjected to antibacterial screening. In a first round of screening
选择2-(1,2-二氢-3-氧代-3H-吡唑-2-基)苯并噻唑支架作为发现新型抗菌化合物的中心核心结构。氧代-吡唑部分以及苯并部分上的取代基的系统变化导致产生了一个小而集中的苯并噻唑文库,该库进行了抗菌筛选。在第一轮筛选中,确定了化合物对六种代表性微生物的活性。对于最有效的同类物,确定了针对金黄色葡萄球菌和铜绿假单胞菌的MIC值。结构-活性关系研究清楚地表明,细微的结构变化在很大程度上影响抗菌活性。最有效的同类物显示的MIC值为3.30μM。
