The synthesis of a benzopentathiepin “conjugated” to a ceramide has been accomplished. The polysulfane-ceramide conjugate was synthesized in 9 steps and 1.6% overall yield. The final step of the synthesis involved the reaction of 7-carboxybenzopentathiepin p-nitrophenyl ester with D-erythrosphingosine, which led to the formation of an amide bond. The development of conjugation chemistry of polysulfanes beyond our lead ceramide compound should unveil which conjugate moieties are best suited to polysulfanes to facilitate drug delivery.
