Described herein are anti-cancer compounds composed of a macromolecule comprising (1) at least one anti-cancer agent directly or indirectly bonded to the macromolecule and (2) at least one high Z element directly or indirectly bonded to the macromolecule that is capable of producing Auger electrons upon exposure to X-ray energy. When the compounds are exposed to low energy X-ray (e.g., kilo electron volts KeV) Auger electrons are produced by the high Z elements present in the compound. Because lower energy is required when compared to typical radiotherapy, which uses therapeutic X-ray energy in the million electron volt range (MeV), the subject experiences lower collateral damage when compared to radiation therapy. Additionally, the presence of the anti-cancer agent provides a second mechanism for killing cancer cells. Methods for making and using the anti-cancer compounds are also described herein.
本文描述了一种抗癌化合物,由包括(1)至少一种直接或间接与大分子结合的抗癌药物和(2)至少一种直接或间接与大分子结合的高Z元素组成,该高Z元素在暴露于X射线能量时能够产生奥古尔电子。当这些化合物暴露于低能量X射线(例如,千电子伏特KeV)时,化合物中存在的高Z元素会产生奥古尔电子。与使用百万电子伏特范围内的治疗性X射线能量(MeV)的典型放射疗法相比,所需的能量更低,因此受试者在与放射疗法相比时经历较低的附带损伤。此外,抗癌药物的存在提供了杀死癌细胞的第二机制。本文还描述了制备和使用抗癌化合物的方法。
