摘要:Disclosed are methods, systems, components, and compositions for synthesis of sequence defined polymers. The methods, systems, components, and compositions may be utilized for incorporating novel substrates that include non-standard amino acid monomers and non-amino acid monomers into sequence defined polymers. As disclosed herein, the novel substrates may be utilized for acylation of tRNA via flexizyme catalyzed reactions. The tRNAs thus acylated with the novel substrates may be utilized in synthesis platforms for incorporating the novel substrates into a sequence defined polymer.

摘要:The present invention relates to a novel thieno[3,2-b]pyridine-5(4H)-one derivative compound, a preparation method thereof, and a use thereof. The novel thieno[3,2-b]pyridine-5(4H)-one derivative compound according to the present invention is synthesized via an aza-[3+3] cyclization addition reaction using BOP, wherein the compound is obtained by synthesizing a 4-arylthiophen-3-amine in which aryl groups such as 4-piperidyl-C6H4, 4-pyrrolidyl-C6H4, 4-MeOC6H4, 3,4,5-(MeO)3C6H4, C6H5, 4-C6H5C6H4, and 4-F3COC6H4 are introduced via a synthesis process by a bromination reaction, a hydrolysis reaction, a decarboxylation reaction, and a Suzuki coupling reaction of methyl 3-aminothiophene carboxylate, and by synthesizing 4-arylthiophen-3-amine and mono-methyl fumarate via a formal aza-[3+3] cyclization addition reaction using BOP and conjugation. Accordingly, novel thieno[3,2-b]pyridine-5(4H)-one derivative compounds according to the present invention have fluorescence properties with a wide range of emission wavelengths and thus may be utilized in various industrial fields such as physics, chemistry, and biomedical research.
