Macrocyclic Spermidine Alkaloids from Maytenus mossambicensis (KLOTZSCH) BLAKELOCK In addition to celabenzine ( 1 ), three new macrocyclic spermidine alkaloids cyclocelabenzine ( 2 ), isocyclocelabenzine ( 3 ) and hydroxyisocyclocelabenzine ( 4 ) have been isolated from Maytenus mossambicensis (klotzsch) blakelock, var. mossambicensis . The three alkaloids show the 13‐membered lactam ring of celabenzine being linked to the benzoyl residue within the spermidine unit. Hydroxyisocyclocelabenzine ( 4 ) is the first known spermidine alkaloid with a hydroxy function at the macrocyclus. The structural elucidation was based mainly on spectroscopic methods, specially 1 H‐ and 13 C‐NMR. spectroscopy.
