The synthesis of a diterpene natural product that potentiates the activity of β-lactam antibiotics against methicillin-resistant Staphylococcus aureus, and its stereochemical confirmation via X-ray crystallography is reported. In addition, analog synthesis and subsequent structure–activity relationship studies propose a mode of action involving mecA and suggest simplification of the scaffold is possible
报道了一种二萜天然产物的合成,该产物可增强 β-内酰胺类抗生素对耐甲氧西林金黄色葡萄球菌的活性,并通过 X 射线晶体学对其进行立体化学确认。此外,模拟合成和随后的构效关系研究提出了一种涉及mecA 的作用模式,并表明支架的简化是可能的。
