Modifications of monotropolone 2 having poor potency against P388 in mice were studied. The alpha-ethoxy group of 2, prepared from hinokitiol and benzaldehyde diethyl acetal, was replaced with a phenolic or heteroaromatic compound by heating 2 with the appropriate nucleophile. Structure-activity relationships indicated that an acidic hydroxyl and a proton-accepting group situated in the neighboring
研究了对小鼠中P388效力较弱的单托酚酮2的修饰。由扁柏酚和苯甲醛二乙缩醛制备的2的α-乙氧基通过与适当的亲核试剂一起加热2被酚或杂芳族化合物取代。结构-活性关系表明,酸性羟基和位于相邻位置的质子接受基团允许与金属离子形成螯合物,有助于提高活性。在研究的化合物中,8-羟基喹啉类似物10f是最有利的化合物。
