Anthraquinone derivatives are constructed for alkylation of target molecules. The anthraquinone derivative includes an anthraquinone ring system which has been modified by the addition of inducibly reactive substituents at positions on the ring system. The anthraquinone ring system can be selectively activated for alkylation of a target molecule. The substituents may be from 1 to 4 methyl groups, whereupon activation is achieved by a photochemical signal. In an additional alternative embodiment, the inducible reactive substituents may include both methyl groups and substituted methylene groups. In this embodiment, the activation of the anthraquinone derivative is achieved by photochemical and/or reductive signals. Alternatively, the substituents may be from 1 to 8 methyl groups modified to include a reactive group, whereupon activation is achieved by a chemical or enzymatic reductive signal. The anthraquinone derivatives of the invention may be used for non-specific modification of target molecules. Alternatively, the anthraquinone derivative may be further derivatized to permit specific modification of target molecules. The further derivatization of the anthraquinone includes attaching a probe to the anthraquinone ring system by way of a linking group. The probe is chosen to selectively localize to a target molecule, whereupon the anthraquinone derivative may be activated to react with and aklylate the target molecule. Also the process of employing such anthraquinone derivatives for use in vitro or in vivo for alkylating, specifically or non-specifically alkylating, target molecules.
蒽醌衍生物被构建用于烷基化目标分子。该蒽醌衍生物包括一个被改性的蒽醌环系统,该系统在环系统上的位置添加了可诱导反应的取代基。蒽醌环系统可以被选择性激活,以烷基化目标分子。取代基可以是1到4个甲基基团,通过光化学信号实现激活。在另一种替代实施方案中,可诱导反应的取代基可能包括甲基基团和取代亚甲基基团。在这种实施方案中,蒽醌衍生物的激活是通过光化学和/或还原信号实现的。或者,取代基可以是1到8个甲基基团,经修饰后包括反应基团,通过化学或酶促还原信号实现激活。本发明的蒽醌衍生物可用于目标分子的非特异性修饰。或者,蒽醌衍生物可以进一步衍生化,以允许特定的目标分子修饰。蒽醌的进一步衍生化包括通过连接基将探针附加到蒽醌环系统上。选择探针以选择性地定位到目标分子,然后可以激活蒽醌衍生物以与目标分子反应并烷基化。此外,本发明还涉及使用这种蒽醌衍生物在体外或体内用于烷基化、特异性或非特异性烷基化目标分子的过程。
