XH-07 is an innovative ionizable cationic lipid that forms the backbone of the JCXH-211 lipid nanoparticle (LNP) delivery system. This complex is engineered to encapsulate and deliver self-replicating RNA (srRNA) encoding interleukin-12 (IL-12), a potent immunostimulatory cytokine. The LNP formulation featuring XH-07 exhibits optimal physicochemical properties, such as a mean particle size of approximately 82.12 nm with low polydispersity, and a near-neutral zeta potential around -3.181 mV, which facilitates stable circulation and efficient cellular uptake upon intravenous administration. Upon delivery, the srRNA leverages the host cell's machinery to produce sustained levels of IL-12p70, as demonstrated in B16F10 tumor-bearing mice, where a single dose led to peak cytokine production in sera and tumors. This induced IL-12 expression activates T cells and NK cells, generating a robust antitumor response. In murine models of melanoma and breast cancer, JCXH-211 monotherapy resulted in significant tumor regression and complete responses in some subjects, and it synergized with anti-PD-1 therapy to enhance efficacy. Importantly, the safety profile was acceptable, with transient liver enzyme elevations in mice that normalized quickly, and no significant adverse events in cynomolgus monkeys after repeated dosing, as evidenced by stable clinical observations and pathology tests. Thus, XH-07 is pivotal for enabling the safe and effective delivery of IL-12 encoding RNA, positioning JCXH-211 as a promising cancer immunotherapy.

Compound 22, as detailed in United States Patent US 2026/0014089 A1, is a bifunctional ionizable lipid engineered for precision drug delivery. Its structure integrates a monosaccharide targeting headgroup, designed to bind specifically to DC-SIGN receptors on dendritic cells, via a sophisticated linker connected to a biodegradable lipid anchor. This design enables it to serve as a key component of lipid nanoparticles (LNPs), forming a targeted delivery system. By leveraging the specific carbohydrate-receptor interaction, these LNPs are preferentially internalized by dendritic cells, critical for initiating adaptive immune responses. In vivo studies from the patent, such as the biodistribution data shown in Figure 5, confirm effective accumulation in lymphoid tissues like the spleen and lymph nodes. Consequently, this targeted delivery enhances the potency of encapsulated payloads (e.g., mRNA vaccines) by ensuring professional antigen presentation, eliciting a stronger and more specific immune response—evidenced by higher neutralizing antibody titers—making it a powerful tool for next-generation vaccines and therapeutics.

AP60 is a novel, biomimetic ionizable lipid, identified as the lead compound from a library of 67 aminophosphonate-derived lipids. Inspired by the structure of natural phospholipids, it forms the core component of lipid nanoparticles within the CROSS delivery platform. AP60-based LNPs demonstrate superior efficiency in delivering mRNA and circular RNA to neuronal cells and astrocytes compared to the clinically used MC3 LNP. In a mouse model of spinal cord injury, AP60 LNPs achieved significantly higher protein expression at the lesion site (13.7-fold locally, 4.6-fold intravenously) while concurrently reducing off-target accumulation in the liver by nearly 5-fold. This indicates improved targeting to the central nervous system injury site and a potentially better safety profile. Its cellular uptake is primarily mediated by clathrin-mediated endocytosis and macropinocytosis, followed by efficient endosomal escape. By encapsulating therapeutic circular RNAs encoding Sox2, Ascl1, and GDNF, AP60 LNPs enable effective in vivo reprogramming and neuroprotection, leading to significant functional recovery of bladder and locomotor functions after spinal cord injury.

Lipid OC7, as described in the patent WO2022207938A1, is a novel ionizable lipid that serves as the core functional component of the saNppa-LNP delivery system. Its key innovation lies in its unique biodegradable structure featuring an internal ester bond. Under typical physiological conditions, this bond hydrolyzes, triggering a charge shift from a cationic form that complexes nucleic acids to a zwitterionic form that releases them. This property is central to its role in enabling long-acting self-amplifying RNA (saRNA) therapies. Specifically, OC7 facilitates immune stealth by mitigating early interferon responses, supports sustained and efficient intracellular replication of saRNA even at low doses, and enables therapeutic protein expression that persists for over 28 days from a single administration. This combination of efficient delivery, controlled release, and extended duration of action makes OC7-based LNPs a promising platform for long-term treatments, such as for myocardial infarction, as demonstrated in the referenced research.
