AMG514 is a novel ionizable lipid designed for formulating spleen-targeting lipid nanoparticles (LNPs) to deliver immune‑remodeling mRNAs (IR‑mRNAs). Its key advantage lies in the formation of a unique “protein corona” enriched with vitronectin, coagulation factors, and specific apolipoproteins (e.g., ApoA‑IV), together with its relatively high apparent pKa (~7.5), which actively redirects LNPs to the spleen instead of the liver. This precise spleen‑targeting property enables efficient transfection of splenic antigen‑presenting cells (APCs). As a vaccine adjuvant, AMG514‑LNPs therefore elicit a more robust activation of adaptive immunity compared to conventional LNPs (e.g., cKK‑E12), generating significantly enhanced antigen‑specific CD8⁺ T‑cell and antibody responses, and inducing durable anti‑tumor immune memory in preclinical models.

In vivo, a single intratumoral dose of AA15V LNP-sSE-SCTs suppressed tumor growth by 22-fold in vaccinated mice, synergizing with checkpoint inhibitors (anti-PD-1/CTLA-4) for complete regression in 28.6% of lymphoma models. Ex vivo, AA15V enabled SE-SCT expression in human glioblastoma (7.1% CD45− cells) and lung cancer samples (5.8–8.7%), underscoring clinical potential. Key data: pKa ~6.3; encapsulation: 85–89%; zeta: +4–6 mV; size: 102.3 ± 4.1 nm. 

ST12 is a lipid-conjugated DMXAA prodrug designed for temporally controlled STING activation in mRNA vaccine formulations. Its structure integrates a mouse-specific STING agonist, a biodegradable ester linker, an RNA-interacting tertiary amine domain, and two hydrophobic tails. When incorporated as a partial replacement for SM-102, ST12 preserves early antigen mRNA translation and subsequently releases DMXAA to activate STING. This delayed activation supports localized type I interferon signaling, enhanced antigen-specific CD8-positive T-cell responses, and improved antitumor immunity. In preclinical OVA and HPV tumor models, ST12-based Syn-STING vaccines suppressed tumor growth and prolonged survival. ST12 remains a preclinical research lipid developed specifically around DMXAA-sensitive STING systems.
