Recently, SINOPEG's self-developed products, mPEG-DTA-1 and HO-PEG-DTA-5, have been formally granted European patents! This marks the recognition of domestically produced high-end LNP excipients by the international regulatory system, laying a solid foundation for China's innovative drugs to enter the global market! As core components of the LNP delivery system, the structure of PEG lipids decisively influences the safety, stability, and immunogenicity of the formulation. SINOPEG has always been committed to the research and development of new technologies and products, and has already secured a significant position in the field of domestic PEG lipid R&D. The newly authorized mPEG-DTA-1 and HO-PEG-DTA-5 are important achievements of the company's continuous innovation in the PEG lipid field. Innovation Breakthrough: mPEG-DTA-1 and HO-PEG-DTA-5 Granted European Patents HO-PEG-DTA-5 is a PEG lipid containing a hydroxyl terminal, which, together with its structural counterpart mPEG-DTA-1, forms the core layout of SINOPEG's product series in this category. To date, these two products have completed their global intellectual property layout: they obtained Chinese patent authorization back in 2023 (Patent No.: ZL202280003648.7) and recently received European patent authorization. (Screenshot source: European Patent Office, Link: https://register.epo.org/application?number=EP22784092&tab=main) Meanwhile, the independently developed mPEG-DTA-1 has already completed its filing with the CDE (Filing No.: F20230000444) and DMF submission (Filing No.: 039451). Even more encouragingly, HO-PEG-DTA-5 will soon complete dual submissions in China and the US, providing strong excipient support and registration convenience for Chinese innovative pharmaceutical companies aiming for the international mainstream pharmaceutical market!

LNP Technology: A Revolutionary Nano-Delivery Platform Lipid Nanoparticles (LNP), as one of the most successful nano-delivery carriers, have demonstrated exceptional capabilities in delivering cytotoxic chemotherapeutic drugs, antibiotics, and nucleic acid therapeutics. In recent years, with the rapid development of mRNA vaccines and drugs, the importance of LNP technology has become increasingly prominent, making it a focal point in the global pharmaceutical field. The granting of European patents for SINOPEG's products not only reflects the international intellectual property system's recognition of China's innovative achievements but also signifies that Chinese companies are steadily moving towards the center stage in the field of high-end pharmaceutical raw materials, potentially injecting new vitality into the global development of LNP technology. Product Portfolio: Extensive Layout Meets Diverse Needs Leveraging profound technical expertise, SINOPEG has developed a variety of novel PEG-lipid structures, providing more high-quality options for glo...

This golden autumn, SINOPEG ventured to Europe with its innovative products and solutions, making consecutive appearances at two premier international industry exhibitions within two months, engaging in deep exchanges with global pharmaceutical elites. CPHI Frankfurt 2025 (Frankfurt, Germany, Oct 28-30) As the world's largest and most influential professional event for the pharmaceutical industry, CPHI Frankfurt brought together industry elites from across the globe. In this grand gathering, SINOPEG attracted numerous visitors with its professional technical sharing. During the exhibition, we prominently showcased our latest achievements in areas such as in vivo CAR-T delivery, Antibody-Drug Conjugate (ADC) linkers, and block copolymers. We held in-depth discussions with multiple potential clients and partners from Europe, North America, and Asia! Many international clients praised our continuously improving R&D capabilities and product quality control system. TIDES Europe 2025 (Basel, Switzerland, Nov 11-13) Following closely, we moved to Switzerland to participate in TIDES Europe, an exhibition focused on oligonucleotides, peptides, mRNA therapies, and related fields. As one of the fastest-growing segments in biopharmaceuticals, TIDES provided us with a valuable platform for direct dialogue with global top experts. Here, we shared SINOPEG's technical expertise and project experience in fatty acid-modified side chains, LNP delivery material production, and related CMC services, attracting numerous biotechnology companies seeking reliable CDMO partners in this field. Through exchanges with industry benchmark companies, we further clarified our future technological development direction and innovation priorities. The successful participation in these two consecutive exhibitions allowed us to clearly grasp the development pulse of the global pharmaceutical industry chain. We deeply felt that CDMO enterprises from China are increasingly winning the trust of the global market, thanks to their continuously enhancing technical capabilities, flexible service models, and reliable quality systems. Two expeditions, two stages of growth. We brought back customer recognition, partner trust, and market insights – all of which will be invaluable assets for SINOPEG's future development! SINOPEG's journey on the international stage has just begun. We will continue to deepen our core technologies and expand our global footprint. Next year, we will appear on broader international stages, bringing more innovative solutions 'Made in China' to the global pharmaceutical industry. Stay tuned!

Review Mol Ther. 2017 Jul 5;25(7):1467-1475.  doi: 10.1016/j.ymthe.2017.03.013.  Epub 2017 Apr 13. Lipid Nanoparticle Systems for Enabling Gene Therapies Abstract Genetic drugs such as small interfering RNA (siRNA), mRNA, or plasmid DNA provide potential gene therapies to treat most diseases by silencing pathological genes, expressing therapeutic proteins, or through gene-editing applications.  In order for genetic drugs to be used clinically, however, sophisticated delivery systems are required.  Lipid nanoparticle (LNP) systems are currently the lead non-viral delivery systems for enabling the clinical potential of genetic drugs.  Application will be made to the Food and Drug Administration (FDA) in 2017 for approval of an LNP siRNA drug to treat transthyretin-induced amyloidosis, presently an untreatable disease.  Here, we first review research leading to the development of LNP siRNA systems capable of silencing target genes in hepatocytes following systemic administration.  Subsequently, progress made to extend LNP technology to mRNA and plasmids for protein replacement, vaccine, and gene-editing applications is summarized.  Finally, we address current limitations of LNP technology as applied to genetic drugs and ways in which such limitations may be overcome.  It is concluded that LNP technology, by virtue of robust and efficient formulation processes, as well as advantages in potency, payload, and design flexibility, will be a dominant non-viral technology to enable the enormous potential of gene therapy.
