DC67538	XH-04	XH-04 (Lipid#4) is an ionizable lipid engineered for advanced mRNA delivery developed by JiaChen West Lake Biotech. Its core structure features a central benzene ring with asymmetric hydrophobic tails (C9-C10 chains) and pH-responsive tertiary amines that enable efficient mRNA encapsulation and endosomal escape. As detailed in CN113993839A, XH04 outperforms industry benchmarks (e.g., MC3 lipid), boosting protein expression by >10-fold in BHK cells. In PCT/CN2024/121624, JiaChen further demonstrated its utility in lung-targeted LNPs (tLNP/tLCNP). When combined with cationic lipids (e.g., DOTMA at 2:1 molar ratio), XH 04 redirects >80% of mRNA delivery to murine lungs—overcoming liver tropism—while maintaining low toxicity. The lipid’s benzenic core and optimized alkyl chain geometry (patent claims 1-9) are credited for enhanced endosomal disruption and mRNA release kinetics. JiaChen’s innovations position XH-04 as a cornerstone for next-generation mRNA therapeutics.
DC60855	4A3-SC7	4A3-SC7 is a proprietary, ionizable lipid component central to the SORT LNP platform developed for targeted organ delivery. It features a unique branched-tail structure designed to enhance mRNA encapsulation and endosomal escape. In the study, it served as the primary ionizable lipid in both Liver SORT LNPs and updated Lung SORT LNPs. For liver targeting, it was formulated at 15.04 mol% alongside helper lipids (DOPE: 23.04%, Cholesterol: 38.72%), PEG-lipid (DMG-PEG2000: 3.2%), and the liver-targeting lipid 4A3-Cit (20 mol%). This specific composition (Total lipid:RNA = 20:1 wt/wt) yielded LNPs with ~74 nm size, low PDI (0.17), and high encapsulation efficiency (87%) for large mRNAs like ABE editors (~5000 nt). Its branched-tail architecture was critical for stabilizing nanoparticles encapsulating large RNAs, overcoming a key limitation of previous formulations. 4A3-SC7-based Liver SORT LNPs enabled >40% base editing in hepatocytes in vivo, achieving durable correction of the disease-causing SERPINA1 mutation in PiZ mice and significantly reducing pathological protein aggregates. In the updated DualSORT system, 4A3-SC7 was also paired with DORI (instead of DOTAP) for improved lung targeting, demonstrating its versatility as a foundational ionizable lipid for multi-organ gene editing therapeutics.
DC67525	Hopewell Lipid 649	L649 is a next-generation, lung-targeting ionizable lipid specifically designed for systemic mRNA delivery developed by Hopewell. Belonging to the novel "N-series" lipid class, it features a unique structure with an amine-containing head group and hydrophobic tails incorporating amide bonds. This design enables L649 to form highly stable lipid nanoparticles (LNPs) that exhibit exceptional tropism for the lower respiratory tract (lungs, bronchi, trachea) following intravenous administration. It demonstrates superior efficiency in delivering therapeutic payloads (like mRNA) specifically to key lung cell types, including alveolar epithelial cells (AT1 and AT2) and bronchial cells, while minimizing off-target accumulation in organs like the liver. L649-based LNPs, particularly when formulated with helper lipids like POPE, combine high potency with significantly improved tolerability, allowing for effective dosing in vivo. This makes L649 a promising candidate for developing treatments for various lung diseases such as pulmonary fibrosis, COPD, lung cancer, and infectious diseases like COVID-19.

It demonstrates exceptional lung-targeted mRNA delivery with 97.1% selectivity and high protein expression (1.21×10⁸ p/s) in mice. Its slightly positive zeta potential (~3.5 mV) correlates with lung tropism, likely mediated by protein corona enrichment of vitronectin and prothrombin. The β-propionate structure enables pH-sensitive biodegradability for enhanced endosomal escape while maintaining low cytotoxicity (>90% cell viability). This lipid enables organ-specific mRNA delivery without permanently charged additives, outperforming conventional SORT strategies in selectivity and expression efficiency.

These LNPs demonstrate remarkable lung-selective accumulation in mice, showing significantly higher uptake compared to heart, liver, spleen, and kidney tissues. When loaded with PTEN mRNA, PPz-2R1 LNPs effectively restore tumor suppressor function in PTEN-deficient lung cancer cells and inhibit tumor progression in orthotopic models, with enhanced efficacy observed in combination with PD-1 blockade therapy.
DC60809	6Ac1-C12	6Ac1-C12 is an ester-core degradable ionizable cationic lipid designed for mRNA delivery, featuring a unique hexa-acrylate ester core ("6Ac1") conjugated with six N-methyldodecylamine chains ("C12") via solvent-free Michael addition. This branched architecture enables optimal mRNA encapsulation and confers exceptional stability, maintaining consistent ~100 nm particle size for over 30 days at 4°C—crucial for cold-chain storage. With a pKa ≈ 6.0, it facilitates pH-responsive endosomal escape through membrane fusion (80% FRET signal increase at pH 5.5) and efficient cytoplasmic mRNA release.Its composition allows precise organ targeting: in conventional four-component LNPs, 98% hepatic mRNA expression occurs post-IV administration, primarily in endothelial cells (60% transfection efficiency). Cholesterol removal enables lung-specific accumulation and translation via three-component formulations, overcoming historical hepatic off-targeting. The lipid shows negligible cytotoxicity in vitro (>85% cell viability) and no significant organ damage in vivo (ALT/AST/BUN/CREA levels comparable to PBS controls). Its degradable ester core hydrolyzes into smaller metabolites, enhancing biocompatibility. Modular compatibility with DOTAP/DDAB cationic lipids expands applicability for pulmonary or splenic targeting, establishing 6Ac1-C12 as a versatile platform for organ-selective mRNA therapeutics.
