Novel painkillers are urgently needed. The activation of opioid receptors in peripheral inflamed tissue can reduce pain without central adverse effects such as sedation, apnoea, or addiction. Here, we use an unprecedented strategy and report the synthesis and analgesic efficacy of the standard opioid morphine covalently attached to hyperbranched polyglycerol (PG-M) by a cleavable linker. With i...

Acetyl tributyl citrate (ATBC) and dibutyl sebacate (DBS) plasticizers are components of polyvinylidene chloride. These compounds can pass from the polyvinylidene chloride packing films to the enclosed food (Baba et al. 1988). Therefore, there may be a potential hazard to health. Toxicity of these compounds in laboratory animals is well known (Mallette and Haam 1952; Smith 1953; Finkelstein and...
The continuous oligomerization of glycerol for the formation polyglycerol was carried out first time under microwave activation. In presence potassium carbonate, we studied ease handling, effects temperature, flow rate and residence an inexpensive homogeneous commercial catalyst. main linear branched-chain diglycerol triglycerol regioisomers were characterized quantification different isomers r...
Cationic polyelectrolytes with pyridinium and 1,2-dimethylimidazolium functionalities based on a hyperbranched polyglycerol scaffold with a narrow polydispersity were prepared by a polymer analogous reaction in a one-pot synthesis. By the variation of the spacer lengths between the cationic functionalities and polyether scaffold, a simple method was developed to adjust the charge density and fl...
Single-molecule fluorescence techniques have emerged as a powerful approach to understanding complex biological systems. However, a challenge researchers still face is the limited photostability of nearly all organic fluorophores, including the cyanine and Alexa dyes. We report a new, monovalent probe that emits in the far-red region of the visible spectrum with properties desirable for single-...
