chemistry similar to that developed earlier for the disulfur series, compounds were made from 2-halogeno-3-indolecarboxylic acid precursors bearing various polar functionality at the C-3 position and small alkyl substituents at the N-1 position of the indole nucleus. Additional compounds were derived from (R)- or (S)-tryptophan via a novel application of diselenium dichloride as an electrophilic source
合成了少量的2,2'-二硒代双(1H-吲哚)系列,作为我们先前报道的2,2'-二硫代双(1H-吲哚)系列的氧化还原修饰同类物。利用类似于先前为二硫系列开发的化学方法,由2-卤代-3-吲哚羧酸前体制备化合物,所述前体在吲哚核的C-3位带有各种极性官能团,在N-1位带有小的烷基取代基。通过二氯二硒作为二硒的亲电子来源的新应用,从(R)-或(S)-色氨酸衍生出其他化合物,并开发了一种大大改进的制备2,2'-二硫代双(1H-吲哚)同源物的方法利用二氯化硫作为二硫化硫的来源。针对离体表皮生长因子受体(EGFr),血小板源性生长因子受体(PDGFr)和v-src酪氨酸激酶,该系列化合物显示出广泛的抑制活性,对EGFr的IC50 = 0.9至> 100 microM,对PDGFr的IC50 = 3.4至> 50 microM,对v-src为0.4-6.7 microM。通常,色氨酸衍生的化合物对EGFr
