strategy used to obtain the quinone derivatives was initially based on the Diels–Alder cycloaddition between myrcene and several p-benzoquinone derivatives, followed by cyclisation of the prenyl side chain in the case of anthracene-1,4-diones. The most promising compounds, displaying MIC values in the low μg/mL range, were those bearing one or two chlorine atoms attached to the quinone ring. Time-kill curves
进行的27简单和杂环稠合的异戊烯基-1,4-萘醌和1,4-蒽二酮类抗真菌评价体外针对人病原性酵母菌(念珠菌属)和丝状真菌(曲霉属,镰孢属,和毛癣菌属)。最初用于获得醌衍生物的合成策略是基于月桂烯和几种对映体之间的Diels-Alder环加成反应-苯醌衍生物,在蒽-1,4-二酮的情况下,异戊二烯侧链的环化。MIC值在低μg/ mL范围内的最有希望的化合物是那些带有一个或两个氯原子连接在醌环上的化合物。确定的最有效化合物的时间杀灭曲线显示出其抑菌作用模式与伊曲康唑相似。
