Ten new dihydroagarofuran sesquiterpene polyol esters, tripterdines A-J (1-10) were isolated from the stem and branch of Tripterygium wilfordii. The structures of new compounds were elucidated on the basis of extensive spectroscopic analyses, including UV, IR, HRESIMS, NMR, and CD exciton chirality method. The structures of compounds 1, 3, and 6 were confirmed by X-ray crystallographic analyses. The anti-inflammatory and cytotoxic activities were assessed for all the compounds (1-10). Compounds 3, 5 and 10 exhibited potent anti-inflammatory activities with the secretion level of TNF-α ranging from 43.86% to 51.27%, and the IL-6 ranging from 32.44% to 50.64%. In addition, compounds 1, 3, 7 and 9 showed weak cytotoxicities against three human tumor cell lines (Huh7, MCF-7 and HCT-116).

Seven previously undescribed dihydro-β-agarofurans (1-7) together with 28 known compounds were isolated from Celastrus orbiculatus fruits using LC-MS/MS-based molecular networking-guided purification. Their structures were elucidated through 1D and 2D-NMR, HRESIMS analysis, and ECD quantum chemical calculations. The inhibitory effects of all isolated compounds on α-MSH-induced melanin production in B16F0 melanoma cells were tested.

Three new sesquiterpene polyol ester compounds angulatin V [1,15-diacetoxy-2-(α-methyl)-butanoyloxy-4α,6α-dihydroxy-8α-isobutanoyloxy-9-benzoxy--dihydroagarofuran], angulatin W [1,2-diacetoxy-4α,6α-dihydroxy-8-carbonyl-9-benzoxy-15-isobutanoyloxy--dihydroagarofuran], angulatin X [1,28α-triacetoxy-4α, 6α-dihydroxy-9-benzoxy-15-nicotinyl--dihydroagarofuran] (), together with one known compound Putterine B (), were isolated from the root bark of Maxim. The structures of compounds were elucidated by NMR, HRESIMS, IR data, and comparison with the literature data. The anti-inflammatory activity of all compounds was evaluated by measuring nitric oxide production in RAW264.

Article Synopsis
  • A new method was developed to create a key part of dihydroagarofuran by using 6-methoxy-1-tetralone and performing dearomatization followed by Michael addition reactions.
  • A total of 33 synthesized compounds were tested for their insecticidal properties, with one showing an LC value of 0.378 mg/mL, indicating a significant increase in effectiveness compared to the known compound Celangulin V.
  • Research identified that modifications, like adding methyl groups at certain positions and using specific ether groups, enhanced the insecticidal activity, and further analysis using a 3D model helped in understanding the relationship between the compound's structure and its effectiveness.
