phosphate analogues bearing 7-(diethylamino)coumarin (DECM) and 4-bromo-5-hydroxy-2-nitrobenzhydryl (BHNB) groups in a photolabile ester bond were synthesized. The ability of the “caged” ceramide 1-phosphate analogues to release the bioactive parent molecule upon irradiation at 400−500 nm was demonstrated by stimulation of macrophage cell proliferation.

(-)-balanol and all of itsstereoisomers starting from easily available Garner aldehydes are described. Diastereoselective Grignard reactions on Garner aldehydes and ring-closing metatheses are the key steps for the construction of hexahydroazepine subunits. The benzophenone subunits were constructed through coupling of suitably functionalized aromatic aldehyde and bromo components. The synthetic route

The invention relates to novel caged ceramide 1-phosphate (C1P), caged ceramide 1-phosphate derivatives(C1P), and the method of using them for delivering C1P intracellularly in vitro and in vivo, for research and therapeutic purposes. Therapeutic purposes include treatment of diseases associated with cell death, such as neurodegerative diseases, including Alzheimer's disease. The disclosed compositions may also be used for wound healing.
