Lipophilic sulfophenylcarbocyanine dyes: Synthesis of a new class of fluorescent cell membrane probes
摘要:
Two lipophilic sulfophenylcarbocyanine dyes, 3 and 4, were synthesized as a new class of fluorescent cell membrane probes. Compared with other commonly used membrane probes, the new dyes have improved fluorescent quantum yield, retention in cell membranes and are easier to use in staining cells.

The N,N’‐bis(2,6‐dimethylphenyl)oxalamide was discovered as a powerful ligand for Cu‐catalyzedcross‐coupling of arylhalides with hydrazine hydrate, leading to the formation of a variety of aryl hydrazines at 80 oC in water under the assistance of K3PO4 and 4 mol% cetyltrimethylammonium bromide from aryl bromides and aryl iodides. Good to excellent yields were observed in most cases.

The present invention relates to a family of cyanine dyes possessing lipophilic alkyl chains and either one or more reactive functional groups, bromo or chloro, or phenyl, sulfophenyl or polysulfophenyl substituents or combinations thereof. The dyes of the invention are useful for staining membranes in cells or isolated from cells, and are well-retained therein. Additionally, the reactive dyes of the invention are useful for preparing dye-conjugates, thereby conferring the membrane staining ability of the subject dye onto the resulting dye-conjugate.

assays in rat or guinea pig brain membranes and for their opioid antagonist and agonist activities in vitro on the guinea pig ileum (GPI) and mouse vas deferens (MVD) preparations. All of the compounds displayed delta selectivity in binding to the delta, mu, and kappa opioidreceptors. The binding potencies of most of the compounds at the delta, mu, and kappa sites, however, were lower than that of 1. Among
