Telomers of Tris(hydroxymethyl)-acrylamidomethane, a new class of non-ionic surfactants: Synthesis and assessment of their properties
Pucci,Pavia
, p. 1437 - 1440 (1991)
A new class of amphiphilic molecules suitable for biological purposes, especially extraction of membrane proteins and/or glycoproteins, is reported. These compounds were prepared by telomerization of a Tris-(hydroxymethyl)-acrylamidomethane monomeric unit in the presence of an alkyl thiol as transfer reagent and of α,α'-(azobis)-isobutyronitrile (AIBN) as initiator. These compounds show similar or better detergent properties than commercially available surfactants.

The polyethylenimine (PEI) derivatives (PTn) are prepared by treating PEI25k with Tris(hydroxymethyl) acrylamidomethane via the Michael addition. These PTns can effectively condense nucleic acids into nanosized particles with positive surface charges. The PTns show lower cytotoxicity and better serum-resistant capacity than PEI25k. Specially, the transfection efficiency of PT26/DNA is 29-fold higher than that of PEI25k in HeLa cells in serum-containing medium. The PTn/siRNA complexes show superior knockdown effect in CT26 cells in serum-containing medium. In addition, flow cytometry analysis shows that the PTns can efficiently mediate the entry of nucleic acids into the cell. Thus, PTns are potentially applicable as non-viral carriers of nucleic acids and warrant further development for use in gene therapy. A series of serum-tolerant PTn conjugates, by introduction of hydroxyl groups onto PEI25k, is designed as dual carriers for nucleic acids delivery. The transfection efficiency of PTn can be up to 29.1-fold higher than that of PEI25k in the serum-containing medium. Meanwhile, PTn with higher endocytosis is more effective in luciferase knockdown compared to PEI25k in the serum-containing medium.

Paragraph 0086-0088, (2017/06/02)
The invention provides a macromolecular crosslinking agent containing polyoxometalates and a preparation method thereof, and application of the macromolecular crosslinking agent containing polyoxometalates in preparation of polyacrylonitrile. Compared with the prior art, the polyoxometalate unit in the macromolecular crosslinking agent has electrically induced discoloration properties, so that the polyacrylonitrile prepared by using the macromolecular crosslinking agent containing polyoxometalates has electrically induced discoloration properties, so that the polyacrylonitrile has a great application prospect in the field of electricity safety. On the other hand, the preparation method provided by the invention is simple in synthetic process, mild in condition, easy to operate, easy to control reaction, high in product purity, and convenient to achieve industrial production, popularization and application.

, p. 9979 - 9987 (2007/10/03)
Biocompatible multifunctional ligands with telomeric structure containing 2-nitroimidazole as affinity marker and tosylate as precursor of 123I radioactive tracer were prepared. Telomerization of appropriate monomers derived from tris(hydroxymethyl)-acrylamidomethane was performed in the presence of dodecanethiol, and either AIBN or tert-butylperoxide. These conjugates are designed to target hypoxic tissues and tumors.
