En grupp antileukemimedel med immunsuppressiva egenskaper som främst erhålls från Ochrosia elliptica (tillhörande familjen Apocynaceae, oleanderväxter). De hämmar både DNA- och RNA-syntes.

I'm sorry for the confusion, but "Ellipticiner" is not a medical term that I am familiar with. It is possible that there may be a spelling error or it could be a term specific to certain languages or industries. If you have more context about where this term came from or what it might refer to, I would be happy to try and help you further.
