We have recently described a novel family of compounds of reduced size and dual anti-HIV and anti-EV71 activity that encompasses tripodal and tetrapodal derivatives. The tripodal prototype, AL-470, has a nitro group at the focal point of the central scaffold and three attached tryptophan residues, each of which bearing an isophthaloyl moiety at the C2 position of the indole ring. A nitro to amino substitution
我们最近描述了一个新的化合物家族,其尺寸减小,具有双重抗 HIV 和抗 EV71 活性,包括三足和四足衍生物。三足原型AL-470在中心支架的焦点处具有硝基和三个附着的色氨酸残基,每个残基在吲哚环的 C2 位置带有间苯二甲酰基部分。硝基到氨基的取代使我们现在能够引入化学可寻址功能,以进行进一步的结构修饰,包括直接和接头介导的几个芳香基团的连接,包括荧光染料 Alexa Fluor 647 和抗体招募 2,4-二硝基苯基基序。一些衍生物被证明比AL-470更有效和更有选择性抗 HIV-1、HIV-2 和 EV-A71。荧光探针显示出对肠道和肺的特定嗜性,这是人类微生物组在健康和疾病方面的两个重要生态位。
