A New Route for Installing the Isocyclic Ring on Chlorins Yielding 131-Oxophorbines
摘要:
A new route to 13(1)-oxophorbines, the parent macrocycle of chlorophylls, begins with the synthesis of a 13-bromochlorin. Pd-mediated coupling of the latter with tributyl(1-ethoxyvinyl) tin and subsequent acidic hydrolysis afforded the 13-acetylchlorin (1). Treatment of 1 with NBS afforded the 15-bromo analogue in 70% yield. Pd-mediated alpha-arylation closed the isocyclic ring to give the 13(1)-oxophorbine (2) in 85% yield. Facile access to 13(1)-oxophorbines should enable a variety of spectroscopic studies and diverse applications.

The present invention provides compounds of the general Formula DI: along with methods of making such compounds, formulations containing the same, and methods of using the same (e.g., in photodynamic therapy, for the production of solar cells, etc.)
The present invention provides a method of detecting (e.g., by flow cytometry) a target compound, cell or particle, wherein the target is labelled with a detectable luminescent compound. The method comprises utilizing as the detectable luminescent compound a compound comprising a porphyrinic macrocycle such as a porphyrin, chlorin, bacteriochlorin, or isobacteriochlorin. In particular embodiments, the detectable luminescent compound comprises a compound of the formula A-A′-Z-B′—B, wherein: A is a targeting group or member of a specific binding pair that specifically binds the detectable luminescent compound to the target compound, cell or particle; A′ is a linker group or covalent bond; B′ is a linker group or covalent bond; B is a water-soluble group; and Z is the porphyrinic macrocycle.
