Embodiments of the synthesis, radiolabeling and biological applications of an activatable tracer that undergoes intramolecular cyclization and aggregation upon activation by cleavage of a blocking moiety are provided. The probes of the disclosure allow for target-controlled self-assembly of small molecules in living subjects for imaging and drug delivery. The aggregated nanoprobes of the disclosure may be detectable optically, by PET detection, magnetic resonance imaging, and the like depending on the detectable reporter attached to the nanoprobe.

(“tail”) were shown to be nanomolar inhibitors in enzymatic and cellular assays. We investigated here the effect of different mitochondrion-targeting cations and other scaffold modifications on the in vitro activity of this class of inhibitors. Low micromolar range activities were obtained, and the structure–activity relationship studies showed that modulation of the tail region with polar substituents
锥虫替代氧化酶 (TAO),一种参与血流呼吸的线粒体酶,形成布氏锥虫的锥鞭毛体,是针对非洲锥虫的经过验证的药物靶点。具有 2,4-二羟基-6-甲基苯甲酸支架(“头部”)和三苯基鏻或 quinolin-1-ium 阳离子作为线粒体靶向基团(“尾部”)的早期 TAO 抑制剂系列被证明是纳摩尔抑制剂在酶和细胞分析中。我们在这里研究了不同的线粒体靶向阳离子和其他支架修饰对这类抑制剂的体外活性的影响。获得了低微摩尔范围的活性,并且构效关系研究表明,用极性取代基调节尾部区域通常不利于 TAO 抑制剂的酶和细胞活性。
