title: Catharanthus alkaloids XXXVII. 16-Epi-Z-isositsirikine, a monomeric indole alkaloid with antineoplastic activity from Catharanthus roseus and Rhazya stricta.
abstract: 16-Epi-Z-isositsirikine (1) has been isolated from the leaves of Catharanthus roseus and Rhazya stricta and identified through a combination of spectral interpretation and chemical correlation. The compound displayed antineoplastic activity in the KB test system in vitro and the P-388 test system in vivo.
