candidates for ROMs featuring exceptional stability and high redox potentials. While simple 1,2- and 1,3-squaric acid amides (SQAs), initially reported by Hünig and coworkers decades ago, turned out to exhibit low stability in their radical cation oxidation states, we demonstrate that embedding the nitrogen atoms into a quinoxaline heterocycle leads to robust two-electron SQX redox systems.

寻找新的氧化还原活性有机材料(ROM)对于开发可持续能源存储解决方案至关重要。在这项研究中,我们提出了一类新的环丁[ b ]喹喔啉-1,2-二酮或方酸喹喔啉(SQX),作为具有出色稳定性和高氧化还原电位的ROM的极有前途的候选者。虽然简单的 1,2- 和 1,3-方酰胺 (SQA) 最初由 Hünig 及其同事几十年前报道,结果证明其自由基阳离子氧化态稳定性较低,但我们证明将氮原子嵌入喹喔啉中杂环导致强大的双电子 SQX 氧化还原系统。制备了一系列 SQX 化合物及其相应的自由基阳离子,并对其进行了充分表征,包括 EPR 光谱、紫外可见光谱和 X 射线衍射。基于新型 ROM 的良好电化学性能和高稳定性,我们开发了 SQX 功能化聚合物,并研究了它们在储能应用中的物理和电化学性能。这些聚合物在远高于 200 °C 时表现出卓越的热稳定性,具有可逆氧化还原特性,相对于 Li + /Li 的电势约为

Chemical conjugates which comprise oligopeptides, having amino acid sequences that are selectively proteolytically cleaved by free prostate specific antigen (PSA) and known cytotoxic agents are disclosed. The conjugates of the invention are characterized by attachment of the cleavable oligopeptide to the oxygen atom at the 4-position on a vinca drug that has be desacetylated. Such conjugates are useful in the treatment of prostatic cancer and benign prostatic hypertrophy (BPH).

species (ROS) is both a consequence and driver of the upregulated metabolism and proliferation of transformed cells. The resulting increase in oxidativestress is postulated to saturate the cellular antioxidant machinery, leaving cancer cells susceptible to agents that further elevate their intracellular oxidativestress. Several small molecules, including the marine natural product cribrostatin 6, have
