An A-B-C type triblock copolymer, tandemly aligning two types of polycations with different pKa values in a single polymer strand, was developed for the construction of novel polyplex micelles, satisfying a high DNA condensing ability as well as a proton buffering activity directed to elevating gene transfection. The micelle might feature the distinctive three-layered structure, where an inner polyplex layer of condensed pDNA with poly(l-lysine) (pKa ?9.4) as the C segment is successively wrapped with an intermediate layer of poly[(3-morpholinopropyl)aspartamide] (B segment) with a comparatively low pKa of?6.2, to provide a buffering effect, and an outer PEG layer (A segment) as a biocompatible palisade.

Novel thermoplastic elastomers based on multi-block copolymers of poly(l-lysine) (PLL), poly(N-epsilon-carbobenzyloxyl-l-lysine) (PZLL), poly(epsilon-caprolactone) (PCL), and poly(ethylene glycol) (PEG) were synthesized by combination of ring-opening polymerization (ROP) and chain extension via l-lysine diisocyanate (LDI). SEC and 1H NMR were used to characterize the multi-block copolymers, with number-average molecular weights between 38,900 and 73,400 g/mol. Multi-block copolymers were proved to be good thermoplastic elastomers with Young’s modulus between 5 and 60 MPa and tensile strain up to 1300%. The PLL-containing multi-block copolymers were electrospun into non-woven mats that exhibited high surface hydrophilicity and wettability. The polypeptide?polyester materials were biocompatible, bio-based and environment-friendly for promising wide applications.

Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. COA of Formula: C15H18N2O5. Introducing a new discovery about 1676-86-4, Name is (S)-Benzyl (4-(2,5-dioxooxazolidin-4-yl)butyl)carbamate

A new type of metallopolymer-polypeptide block copolymer poly(ferrocenyldimethylsilane)-b-poly (e-benzyloxycarbonyl-L-lysine) was synthesized by ring-opening polymerization of epsilon-benzyloxycarbonyl-L-lysine N-carboxyanhydride initiated by using a primary amino-terminated poly(ferrocenyldimethylsilane). Studies on the self-organization behavior of this polypeptide block copolymer in both the bulk state and in solution were performed. In the bulk state, a cylindricalin-lamellar structure was observed in a compositionally asymmetric sample. Rod-like micelles with a polyferrocenylsilane core formed in a polypeptideselective solvent alone or in the presence of a common solvent. Significantly, an additional small quantity of the common solvent assisted the formation of longer micelles and micelles with better shape-regularity. This is attributed to a decrease in the number of nucleation events and PFS core reorganization effects.
