Combinatorial design of nanoparticles for pulmonary mRNA delivery and genome editing
Li, Bowen ; Manan, Rajith Singh ; Liang, Shun-Qing , et al. Nat. Biotechnol.,2023,41(10):1410-1415. DOI: 10.1038/s41587-023-01679-x PubMed ID: 36997680

Abstract: The expanding applications of nonviral genomic medicines in the lung remain restricted by delivery challenges. Here, leveraging a high-throughput platform, we synthesize and screen a combinatorial library of biodegradable ionizable lipids to build inhalable delivery vehicles for mRNA and CRISPR-Cas9 gene editors. Lead lipid nanoparticles are amenable for repeated intratracheal dosing and could achieve efficient gene editing in lung epithelium, providing avenues for gene therapy of congenital lung diseases.

In tetrahydrofuran | 64 N,N-Bis[2-(diethylamino)ethyl]-N'-[2-(phenylsulfonyl)ethyl]urea EXAMPLE 64 N,N-Bis[2-(diethylamino)ethyl]-N'-[2-(phenylsulfonyl)ethyl]urea A mixture of 4.84 g (0.0262 mole) of 2-phenylsulfonylethylamine and 4.90 g (0.030 mole) of 1,1'-carbonyldiimidazole in 400 ml of tetrahydrofuran was stirred at room temperature for 1 hr. A solution of 5.90 g (0.027 mole) of N'-[2-(diethylamino)ethyl]-N,N-diethyl-1,2-ethanediamine in 50 ml of tetrahydrofuran was added, and the solution was refluxed for 16 hr. The solvent was removed in vacuo, and the residue was partitioned between methylene chloride and water. The methylene chloride solution was dried over sodium sulfate, and the solvent was removed in vacuo to give an oil. This was subjected to column chromatography (silica gel, gradiently eluted with methylene chloride-methanol) to give 7.64 g (60.78) of the title compound as an oil.
