Z)-Diene 10 was subjected to the nitroso Diels-Alder reaction to give the 1,4-trans six-membered ring adduct, 4a. The cis isomer 4b was derived from similar nitroso cycloaddition reactions with the corresponding (E,E)-diene and separately from cyclohexadiene. The IC(50) values of 4a and 4b in a NAALADase assay were found to be 0.9 and 0.1 microM, respectively. [reaction: see text]
在计算分析的基础上设计并合成了两个PSMA抑制剂的六元环靶向类似物(4a和4b)。使(E,Z)-二烯10进行亚硝基Diels-Alder反应,得到1,4-反式六元环加合物4a。顺式异构体4b源自与相应的(E,E)-二烯的类似的亚硝基环加成反应,并且独立于环己二烯。发现在NAALADase分析中4a和4b的IC(50)值分别为0.9和0.1 microM。[反应:看文字]
