Considering the resistance of weeds to different herbicides with mechanisms action, search for new, more selective compounds low toxicity other species in nature has been very important development agriculture. Because that, considering biological activity allelochemicals and natural epoxides, four new epoxy derived from dehydrocostus lactone were synthetized evaluated their potential herbicide against three seeds, Allium cepa (onion), Lepidium sativum (garden cress), Lactuca sativa (lettuce). In assays A. cepa, compound 4 inhibited radicle length by 80% at 100 μM. Notably, L. sativum, showed significant inhibition, reducing stalk lengths μM, surpassing performance commercial Logran. However, diol 5 notably growth 28% making most observed effect. One noteworthy lactones studied is epoxide 4. This highlights importance functional group affecting both shoot seeds. Therefore, synthesis these proven advantageous holds great herbicides.

Glioblastoma is one of the most aggressive brain cancers, characterized by active infiltrative growth and high resistance to radiotherapy chemotherapy. Sesquiterpene triterpenoids (STLs) their semi-synthetic analogs are considered as a promising source novel anti-tumor agents due low systemic toxicity multi-target pharmacological effects on key processes associated with tumor progression. The current review aims systematize knowledge anti-glioblastoma potential STLs accumulated over last decade identify in glioblastoma cells that susceptible action STLs. An analysis published data clearly demonstrated STLs, which can successfully cross blood-brain barrier, exert complex inhibitory effect through induction "mitochondrial dysfunction-oxidative stress-apoptosis" axis, inhibition glucose metabolism cell cycle phase transition, suppression motility invasion blockade proneural-mesenchymal transition. Taken together, this highlights not only able induce death, but also effectively affect diffusive spread, suggests possible directions for further investigation context better understand mechanism action.
