Microenvironment-sensitive fluorescent (ESF) nucleosides are powerful tools for nucleic acid research. The new 5-substituted uridine analogues are synthesized, which comprise a 4H-cyclopenta[d]thiazole ring obtained by the Hantzsch synthesis reaction of 5-thioamide-uridine with aromatic α-bromocarbonyl compounds. The emission maximum of new compounds is in the visible region. They exhibit strong solvent-
微环境敏感的荧光(ESF)核苷是用于核酸研究的强大工具。合成了新的5-取代的尿苷类似物,其包含通过5-硫代酰胺-尿苷与芳族α-溴羰基化合物的汉茨(Hantzsch)合成反应获得的4 H-环戊[ d ]噻唑环。新化合物的最大发射量在可见光区域。它们具有很强的溶剂和pH依赖性荧光特性,表明它们有望成为荧光探针。

Disclosed are compounds of Formula A and Formula A-1, or a salt thereof, and pharmaceutical formulations (pharmaceutical compositions) comprising those compounds, or a salt thereof; wherein “R1”, “RA-1”, “R2”, “R3”, and “Het” are defined herein above, which compounds are believed suitable for use in selectively antagonizing the A2a receptors, for example, those found in high density in the basal ganglia. Such compounds and pharmaceutical formulations are believed to be useful in treatment or management of neurodegenerative diseases, for example, Parkinson's disease, or movement disorders arising from use of certain medications used in the treatment or management of Parkinson's disease.
