In 2020,Macromolecular Bioscience included an article by Holm, Regina; Schwiertz, David; Weber, Benjamin; Schultze, Jennifer; Kuhn, Jasmin; Koynov, Kaloian; Laechelt, Ulrich; Barz, Matthias. Safety of H-Lys(Boc)-OH. The article was titled 《Multifunctional Cationic PeptoStars as siRNA Carrier: Influence of Architecture and Histidine Modification on Knockdown Potential》. The information in the text is summarized as follows:
RNA interference provides enormous potential for the treatment of several diseases, including cancer. Nevertheless, successful therapies based on siRNA require overcoming various challenges, such as poor pharmacokinetic characteristics of the small RNA mol. and inefficient cytosolic accumulation. In this respect, the development of functional siRNA carrier systems is a major task in biomedical research. To provide such a desired system, the synthesis of 3-arm and 6-arm PeptoStars is aimed for. The different branched polypept(o)idic architectures share a stealth-like polysarcosine corona for efficient shielding and a multifunctional polylysine core, which can be independently varied in size and functionality for siRNA complexation-, transport and intra cellular release. The special feature of star-like polypept(o)ides is in their uniform small size (<20 nm) and a core-shell structure, which implies a high stability and stealth-like properties and thus, they may combine long circulation times and a deep penetration of cancerous tissue. Initial toxicity and complement studies demonstrate well tolerated cationic PeptoStars with high complexation capability toward siRNA (N/P ratio up to 3:1), which can lead to potent RNAi for optimized systems. Here, the synthetic development of 3-arm and 6-arm polypept(o)idic star polymers, their modification with endosomolytic moieties, and first in vitro insights on RNA interference are reported on.H-Lys(Boc)-OH(cas: 2418-95-3Safety of H-Lys(Boc)-OH) was used in this study.
H-Lys(Boc)-OH(cas: 2418-95-3) belongs to amino acids. In addition to subunits of proteins, amino acids have many other functions as well, including osmoregulation (proline), neurotransmitters (gamma-aminobutyric acid), metabolic intermediates (ornithine and citrulline), and inhibitors (dehydroproline).Safety of H-Lys(Boc)-OH
