可溶形式的聚集 tau 错误折叠蛋白(通常称为寡聚物)被认为是神经退行性疾病病理成分不同组装状态中毒性最强的物种。因此,生物医学界迫切需要能够识别和量化它们的成像探针。我们设计并合成了一种新型荧光探针pTP-TFE ,评估了其对聚集 tau 和 Aβ 蛋白的结合和选择性特征。我们的结果表明,pTP-TFE对早期形式的可溶性 tau 聚集体具有选择性,解离常数 ( K d ) = 66 nM具有高亲和力,选择性是成熟 tau 原纤维的十倍。此外,我们发现pTP-TFE对 tau 蛋白的选择性优于 Aβ 聚集体,并且具有良好的细胞通透性。pTP-TFE对早期形式的体外聚集 tau 蛋白的选择性也得到了对含有 tau 和 Aβ 病理学的人脑组织的研究的支持。据我们所知,这是第一个被报道具有这种形式选择性特征的荧光分子,这表明pTP-TFE是一种独特的候选探针,用于基于成像的阿尔茨海默病和其他 tau蛋白病的早期阶段检测。

for treatment of metastatic castration-resistant prostatecancer (mCRPC), approximately 20–40% of patients have no response to these agents. It has been stipulated that the lack of response and the development of secondary resistance to these drugs may be due to the presence of AR splice variants. HDAC6 has a role in regulating the androgenreceptor (AR) by modulating heat shock protein 90 (Hsp90)

present an alcoholoxidation strategy to access α-trifluoromethyl ketones (TFMKs) merging catalytic oxoammonium cation oxidation with visible-light photoredox catalysis. This work uses 4-acetamido-(2,2,6,6-tetramethyl-piperidin-1-yl)oxyl as an organic oxidant capable of generating TFMKs in good yields. The methodology serves as an improvement over previous reports of an analogous oxidation strategy requiring
