[EN] LIPIDS FOR DELIVERY OF THERAPEUTIC AGENTS [FR] LIPIDES POUR L'ADMINISTRATION D'AGENTS THÉRAPEUTIQUES
摘要:
The current disclosure relates to lipid-based compositions and methods useful in administering therapeutic agents such as, for example, nucleic acids (e.g., siRNA, ASO, tRNA, miRNA, mRNA, DNA, and the like), proteins, peptides, and other macromolecules, which do not have the ability to easily cross a cell membrane. In particular, certain embodiments of the disclosure relate to reversible zwitterionic lipids having a tertiary amine with an increased pKa and extended linker domains (e.g., ≥C3), that may be incorporated into lipid-based compositions (e.g., lipid nanoparticles) to increase efficiency of delivery and release of a therapeutic agent(s) to a subject. The present disclosure provides compositions comprising such reversible zwitterionic lipids, optionally in association with a therapeutic agent (e.g., a therapeutic mRNA and/or nucleic acid controller system), as well as methods of synthesizing the ionizable lipid particle compositions provided herein.

Threading of a polymerthrough a macrocyclicring may occur directly, that is, by finding the end of the polymer chain, or by a process in which the polymer chain first folds and then threadsthrough the macrocyclicring in a hairpin‐like conformation. We present kinetic and thermodynamic studies on the threading of a macrocyclicporphyrin receptor (H21) onto molecular threads that are blocked on one

comprehensive study into the Cp 2 TiCl-mediated reductive epoxide ring opening using either water as a hydrogen source or deuterium oxide as a deuterium source. The remarkable chemical profile of this reaction allows access to alcohols with anti-Markovnikov regiochemistry from different epoxides. The use of D 2 O as a deuterium source leads to an efficient synthesis of β-deuterated alcohols, including a deuterated
我们描述了使用水作为氢源或使用氧化氘作为氘源的 Cp 2 TiCl 介导的还原性环氧化物开环的综合研究。该反应的显着化学特征允许从不同的环氧化物中获得具有抗马尔科夫尼科夫区域化学的醇。使用 D 2 O 作为氘源可有效合成 β-氘化醇,包括酪醇的氘化样品,酪醇是一种包含在橄榄叶中的生物活性化合物,已成功用作食品分析中的内标.
