Synthesis of the antibacterial emodin was improved using Friedel-Crafts acylation as a key step leading to 37% overall yield. In addition, 21 analogues were synthesized by structural modification of the hydroxyl and methyl groups, as well as the aromatic ring of emodin. Antibacterial activity against methicillin-resistant Staphylococcusaureus (MRSA) and cytotoxicity against noncancerous Vero cells
Synthesis of a series of ethylene glycol modified water-soluble tetrameric TPE-amphiphiles with pyridinium polar heads: Towards applications as light-up bioprobes in protein and DNA assay, and wash-free imaging of bacteria
Available online Development of water soluble AIE-active “light-up” bioprobes for the detection of biomacromolecules has drawn huge research interests in recent past. In this study, a series of ethylene glycol modified water soluble tetrameric tetraphenylethylene amphiphiles with pyridinium polar heads (TPE-xEG-Py, x = 3, 4, 6 or 1a-c) have been synthesized by varying the ethylene glycol spacer. Their
可以在线获取用于检测生物大分子的水溶性AIE活性“发光”生物探针的开发在最近几年引起了巨大的研究兴趣。在这项研究中,通过改变乙二醇间隔基,合成了一系列带有吡啶鎓极性头的乙二醇改性的水溶性四聚四苯基乙烯两亲物(TPE-xEG-Py,x = 3、4、6或1a-c)。它们独特的结构使它们能够在水溶液中形成囊泡和其他纳米聚集体。这些两亲物已成功用于基于静电相互作用的荧光检测和BSA和DNA的定量分析,从而触发了TPE部分的AIE发射。在革兰氏阴性菌(大肠杆菌)的免洗成像中,静电相互作用也被证明是非常有效的。)和革兰氏阳性(金黄色葡萄球菌)细菌,在细菌浓度为0–12×10 8 CFU mL -1的情况下,荧光响应增加多达92倍。由于具有成本效益且易于合成,高水溶性和快速响应,该策略是有利的。

In some aspects, the invention relates to an antibody-drug conjugate, comprising an antibody; a linker; and at least two active agents. In preferred embodiments, the linker comprises a peptide sequence of a plurality of amino acids, and at least two of the active agents are covalently coupled to side chains of the amino acids. The antibody-drug conjugate may comprise a self-immolative group, preferably two-self-immolative groups. The linker may comprise an O-substituted oxime, e.g., wherein the oxygen atom of the oxime is substituted with a group that covalently links the oxime to the active agent; and the carbon atom of the oxime is substituted with a group that covalently links the oxime to the antibody.

New fluorinated nonionicsurfactants containing two monodisperse oligo(oxyethylene) tails and having a hydroxyl group in the terminal position were easily obtained, with good yields, a purity higher than 95%, a high solubility in water and show interesting surface properties for their physicochemical application: low surface tensions and noteworthy critical micelle concentrations.
