, p. 7981 - 7986 (2000)
A new series of N-substituted thiocarbamoyl derivatives containing histamine, tryptamine, and other moieties having at least one amino group attached to an aliphatic chain, has been synthesized from (1-thyminyl)thioacetamide in good isolated yields (69-86%). N-[2-(4-Imidazolyl)ethyl](1-thyminyl)thioacetamide was hydrolyzed to its amide on prolonged heating in water. Ammonium sulfide (20-22% solution in water) has found interesting new applications in the efficient synthesis of N-[2-(3-indolyl)ethyl](1-thyminyl)thioacetamide and site selective acylation of diaminoalkanes, starting directly from nitriles.

Melamine driven supramolecular self-assembly of nucleobase derivatives in water

Water-soluble supramolecular polymers, especially made up of biomolecules, are ideally suited to build new biomaterials that can mimic or interact with dynamic, biological environments. Here, two derivatives from thymine (T), that is N-[2-(3,4-Dihydro-5-methyl-2,4-dioxo-1(2H)-pyrimidinyl)acetyl]-L-phenylalanine (T-phe) and N-(2-Aminoethyl)-3,4-dihydro-5-methyl-2,4-dioxo-1(2H)-pyrimidineacetamide (T-NH2) were synthesized. Then the optimal condition for self-assembly of T-phe and T-NH2 driven by melamine (M) was explored. It was observed that M/T kept at 1:3 with equivalent T-phe and T-NH2 under neutral environment resulted in long fibers (>1 μm) with extremely high aspect ratios, which suggested that electrostatic and π-stacking interactions could be effectively orchestrated by hydrogen bonds to direct the hierarchical assembly. Furthermore, hydrogels were spontaneously generated with a concentrated solution of T-phe, T-NH2, and M due to the fibril entanglement. Given its biomimetic nature and efficient self-assembly process, this newly developed supramolecular polymer stacked by tetrameric structures represented an innovative concept and pathway for novel bio-inspired materials.
Thymine-based near-infrared squaraine dye probe and preparation method and application thereof

, (2017/12/30)
The invention relates to the field of dye probe preparation, particularly to a thymine-based near-infrared squaraine dye probe and a preparation method and application thereof. The preparation method comprises taking 1-(3-dimethyl aminopropyl)-3-ethyl carbodiimide and 1-hydroxybenzothioamide as catalysts, N, N-diisopropylethylamine as organic base and dimethyl formamide as solvent to perform key reaction for producing amido bonds, and taking ethylenediamine as truss arm to link thymine and unsymmetric squaraine dyes via covalent bonds to prepare the unsymmetric thymine-based near-infrared squaraine dye probe. Existing near-infrared dye probes mainly focus on recognition of ions of Fe3+, and the thymine-based near-infrared squaraine dye probe solves the problem of selective recognition of Fe2+ and Co2+ in near-infrared absorbing areas.
