对抗生素的耐药性是对人类健康日益严重的威胁,这需要开发新的治疗感染的模式。我们最近确定1(CCG-2979)作为链激酶表达的抑制剂,链激酶是A组链球菌中的一种关键毒力因子,赋予血源性细菌纤溶能力。在这份报告中,我们描述了一系列新的5,6-二氢苯并[h]喹唑啉-4(3 H)-酮类似物1的合成和生物学评价进行的目标是提高适度的效力的铅。除了实现超过35倍的效力增加之外,我们还鉴定了改善支架的溶解度和代谢稳定性的结构修饰。两种新化合物12 c(CCG-203592)和12 k(CCG-205363)对金黄色葡萄球菌中生物膜形成的功效代表了这类新型化合物的有希望的额外作用模式。
Resistance to antibiotics is an increasingly dire threat to human health that warrants the development of new modes of treating infection. We recently identified 1 (CCG-2979) as an inhibitor of the expression of streptokinase, a critical virulence factor in Group A Streptococcus that endows blood-borne bacteria with fibrinolytic capabilities. In this report, we describe the synthesis and biological evaluation of a series of novel 5,6-dihydrobenzo[h]quinazolin-4(3H)-one analogs of 1 undertaken with the goal of improving the modest potency of the lead. In addition to achieving an over 35-fold increase in potency, we identified structural modifications that improve the solubility and metabolic stability of the scaffold. The efficacy of two new compounds 12c (CCG-203592) and 12k (CCG-205363) against biofilm formation in Staphylococcus aureus represents a promising additional mode of action for this novel class of compounds.
