“…The comparison of the experimental Raman and Far IR spectra of the G 0 and the G 2 molecules show their marked difference. Line at 383 cm K1 in the reduced Raman spectra of the G 0 in the crystalline state may be compared with band at 378 cm K1 in the Far IR spectra and assigned to the out of plane and torsion vibrations of aromatic units [7][8][9]. Line at 331 cm K1 of the reduced Raman spectra corresponds to the band at 328 cm K1 in the Far IR spectra of the G 0 and also refers to the out of plane and torsion vibrations of aromatic units.…”

“…Recently we reported about preparation, IR and Raman spectra of the phosphorus-containing dendrimers built up to 12th generation with terminal aldehyde groups and PCl bonds [5][6][7][8][9]. Twelve generations of one series were used to study connection between peculiarities of structure of these compounds and their vibrational spectra [7][8][9].…”

“…Having said that, it is important to point out that even if the secondary and tertiary structure of the native and polymeric protein species are similar, this does not ensure the conjugate will be fully functional, since the polymer can sterically interfere with the intermolecular interactions necessary for activity. Although less frequently used, Fourier-transformed infrared spectroscopy (FTIR) [193] techniques have been also employed in the conformational analysis of polymer conjugates [194] . FTIR can provide, while at a low structural resolution, valuable information about conformational details of these macromolecules.…”

Objective : Clinical proof of concept for polymer conjugates has already been achieved over the last 30 years, with a family of polymer-protein conjugates reaching the market and an exponentially growing list of polymer-drug conjugates currently in clinical trials. However, many challenges and opportunities still lie ahead, providing scope to develop this platform technology further. Methods : The delivery of new anticancer agents aimed at novel molecular targets and their combination, the development of both new polymeric materials with defined architectures and the treatment of diseases other than cancer are the most exciting and promising areas. The latest advances and future trends in the polymer conjugate field will be presented in this article, providing an insight into their potential in the clinics and offering a wide range of research approaches within the scientific community. Results/conclusion : Polymer therapeutics is a rapidly emerging field with exponentially growing opportunities to achieve medical treatments with highly enhanced therapeutic value.

The Chemistry of P=N−P=X (X=S, O, NR) Linkages for the Synthesis of Dendritic Structures

The Staudinger reaction between a phosphine and an azide, applied to phosphorus azides, has been used for the synthesis of a large variety of dendritic structures, incorporating P=NÀ P=X moieties (X = mainly S, but also O and NÀ R). Conjugation of the P=N bond with the P=X bond greatly stabilizes the P=N bond. Highly branched structures such as dendrons, dendrimers, Janus dendrimers, layered dendrimers, surface-block dendrimers, and diverse other dendritic structures incorporating such linkage have been elaborated. Accelerated methods of synthesis of dendrimers are also based on the Staudinger reaction. A versatile reactivity was observed exclusively on the sulfur atom of P=NÀ P=S linkages, such as alkylation or complexation. Alkylation on S induces a weakening of the strength of the P=S bond, which can be easily cleaved to generate phosphines able to react in Staudinger reactions inside the structure of dendrimers, thus affording highly sophisticated dendritic structures.
