Ionizable Lipid Products

Ionizable lipid-3( SM-102 analogu) is a cationic lipid for nucleic acid delivery, with the ability to form lipid nanoparticle mRNA vaccines that exhibit in vitro stability and immunostimulatory activity.This SM-102 analogue retains the ionizable tertiary amine and asymmetric hydrophobic architecture while replacing the ester linkages with carbonate groups and repositioning the hydroxyl functionality. These modifications are designed to tune biodegradability, membrane interactions, and LNP delivery performance.

AA-T3A-C12 is a leading anisamide-tethered lipidoid (AA-lipidoid) identified through a combinatorial library screening for targeted RNA delivery to activated fibroblasts, offering a promising approach to treat liver fibrosis.AA-T3A-C12 is a leading anisamide-tethered lipidoid (AA-lipidoid) identified through a combinatorial library screening for targeted RNA delivery to activated fibroblasts, offering a promising approach to treat liver fibrosis. It is synthesized via a one-pot, two-step modular method that combines anisamide—a ligand for sigma receptors overexpressed on activated hepatic stellate cells (HSCs)—with a T3A polyamine core and C12 epoxide tails, enabling efficient siRNA encapsulation in lipid nanoparticles (LNPs). In vitro, AA-T3A-C12 LNPs exhibit enhanced cellular uptake and gene silencing in activated fibroblasts, dependent on sigma receptor binding, as confirmed by haloperidol blockade studies, and outperform non-targeted analogs and the FDA-approved MC3 LNPs in fibroblast selectivity.In a mouse model of CCl4-induced liver fibrosis, AA-T3A-C12/siHSP47 LNP achieves approximately 65% knockdown of heat shock protein 47 (HSP47), a key fibrotic target, leading to significant reduction in collagen deposition and fibrosis alleviation, with a good safety profile and no exacerbation of liver injury.
