Total Synthesis of the Terpenoid Buddledone A: 11-Membered Ring-Closing Metathesis
摘要:
The first total synthesis of buddledone A was accomplished in seven steps from methyl ethyl ketone (MEK). The key step in the sequence featured an 11-membered ring formation by ring-closing metathesis.
conjugates with salicylic acid or various benzoicacid derivatives were synthesized for evaluations of their antiproliferative effects on Jurkat cells as salicylic acid is bioactive and has a carboxylic group for coupling. Most of them resulted in IC50 values as low as 1–10 μM, validating the utility of this activity-conserving strategy.

The subject matter of the invention is the topical use of zerumbone preferably extracted from Zingiber zerumbet (L.) Smith for the treatment of the deficiencies of the capillary network of the skin, resulting in feelings of heaviness and tingling in the lower limbs. It also helps to treat micro-subcutaneous oedemas, including bags and/or dark circles under the eyes.
