Tailoring Alkyl Side Chains of Ionizable Amino-Polyesters for Enhanced In Vivo mRNA Delivery.
Article in ACS applied bio materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lipid nanoparticles (LNPs) containing ionizable lipids are the most clinically advanced platform for mRNA delivery, but their application beyond the liver remains challenging. Polymer-lipid hybrid nanoparticles offer a promising alternative, combining the synthetic versatility and unique properties of polymers with the biocompatibility of lipid excipients. While the significance of alkyl tail design is well-recognized for ionizable lipids, the impact of the polymer side chain composition on interactions with lipid excipients, mRNA delivery efficacy, and tissue specificity remains poorly understood. Here, we focus on a class of ionizable amino-polyesters (APEs) that exhibit features desired for potential clinical applications, including narrow molecular weight distribution and a good safety profile, and investigate the effect of polymer side chain composition on the formulation of APE lipid nanoparticles (APE-LNPs) for mRNA delivery. A library of 36 APEs was synthesized via ring-opening polymerization of chemically diverse tertiary amino-alcohols and lactone monomers with distinct alkyl side chain compositions, including variations in length and unsaturation. We show that optimal alkyl side chain length is critical for the assembly of stable mRNA nanoparticles and efficient mRNA delivery both
