New maleimide spirobenzopyran derivatives as photochromic labels for macromolecules with sulfhydryl groups
摘要:
Two new photochromic labels of spiro[chromene-2,2'-indole] series supplied with 5-positioned maleimide moieties suitable for labelling macromolecules with sulfhydryl groups were synthesized.
Ethynyl-equipped Spirobenzopyrans as Promising Photochromic Markers for Nucleic Acid Fragments
摘要:
New photochromic markers for nucleic acid fragments, 6'-nitro-substituted spirobenzopyrans equipped with ethynyl group through the appropriate linkers, were subjected to the Sonogashira coupling with model 5-iodo-1,3-dimethyluracil.
