“…Nevertheless, it exhibits important anti-HIV activity 26 and cytotoxicity. 27,28 We have reviewed platanic acid, besides other triterpenoids, and its selected nitrogen-group-bearing derivatives recently. 3 Nevertheless, before the review paper has been published, several new papers have appeared in the literature: pentacyclic triterpenoid sulphamates used for radiotherapy of breast cancer, 29 nitrogen-group-bearing bicyclic compounds used as inhibitors of butyrylcholinesterase, 30,31 pyridinylidene derivatives developed for targeting apoptosis, 32 platanic acid amides 33,34 and even more complex derivatives of platanic acid 35 for investigating cytotoxicity.…”
