RNA contributes to disease pathobiol. and is an important therapeutic target. The downstream biol. of disease-causing RNAs can be short-circuited with small mols. that recognize structured regions. The discovery and optimization of small mols. interacting with RNA is, however, challenging. Herein, we demonstrate a massively parallel one-bead-one-compound methodol., employed to optimize the linker region of a dimeric compound that binds the toxic r(CUG) repeat expansion [r(CUG)exp] causative of myotonic dystrophy type 1 (DM1). Indeed, affinity selection on a 331,776-member library allowed the discovery of a compound with enhanced potency both in vitro (10-fold) and in DM1-patient-derived myotubes (5-fold). Mol. dynamics simulations revealed addnl. interactions between the optimized linker and the RNA, resulting in ca. 10 kcal/mol lower binding free energy. The compound was conjugated to a cleavage module, which directly cleaved the transcript harboring the r(CUG)exp and alleviated disease-associated defects. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Quality Control of 2-Methoxyethylamine).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Quality Control of 2-Methoxyethylamine
