A series of novel 4-(N-acyl)-2,3-dihydro-1H-isoindol-1-ones have been prepared from methyl-3-nitro-2-methylbenzoate and linked through various spacers to the adenosine derivatives 11 and 12. We found that potent inhibition of poly(ADP-ribose)polymerase-1 (PARP-1) was achieved when isoindolinone was linked to adenosine by a spacer group of a specific length.

由3-硝基-2-甲基苯甲酸甲酯制备了一系列新颖的4-(N-酰基)-2,3-二氢-1H-异吲哚-1-酮,并通过各种间隔基连接到腺苷衍生物11和12上。我们发现,当异吲哚啉酮通过特定长度的间隔基团连接到腺苷时,可以有效抑制聚(ADP-核糖)聚合酶-1(PARP-1)。在异吲哚啉酮和腺苷核心结构之间引入哌嗪和琥珀酰连接基可产生强效化合物8a和10b,其IC(50)值分别为45和100 nM。
