Abstract
A chemical investigation of leaves of Viburnum chingii afforded eleven compounds, including one undescribed lignan (1), a pair of known phenylpropanoid enantiomers (2a/2b), and eight known lignans (3-10). Their structures were elucidated by detailed spectroscopic and comparative literature data analysis. The absolute configurations of compounds 1 was determined by comparing the experimental ECD data with the calculated values. The compounds 2a/2b were separated successfully by a chiral chromatographic column. In addition, the acetylcholinesterase (AChE) inhibitory activities of described compounds were evaluated.

NATURAL PRODUCTS AND BIOPROSPECTING 2022; 12:36.

Abstract
11β-Hydroxysteroid dehydrogenase 1 (11β-HSD1) represents a promising drug target for metabolic syndrome, including obesity and type 2 diabetes. Our initial screen of a collection of natural products from Danshen led to the identification of tanshinones as the potent and selective 11β-HSD1 inhibitors. To improve the druggability and explore the structure-activity relationships (SARs), more than 40 derivatives have been designed and synthesized using tanshinone IIA and cryptotanshinone as the starting materials. More than 10 derivatives exhibited potent in vitro 11β-HSD1 inhibitory activity and good selectivity over 11β-HSD2 across human and mouse species. Based on the biological results, SARs were further discussed, which was also partially rationalized by a molecular docking model of 1 bound to the 11β-HSD1. Remarkably, compounds 1, 17 and 30 significantly inhibited 11β-HSD1 in 3T3-L1 adipocyte and in livers of ob/ob mice, which merits further investigations as anti-diabetic agents. This study not only provides a series of novel selective 11β-HSD1 inhibitors with promising therapeutic potentials in metabolic syndromes, but also expands the boundaries of the chemical and biological spaces of tanshinones.

Abstract
Viburnum species are a group of small trees or shrubs that are of great ornamental and medicinal values. Some of them have been used for a long time both as conventional and ethnic medicine. Viburnum fruits, eaten in fresh and processed forms, have been revealed to contain various health-promoting nutrients. With the increasing research on Viburnum plants, they are considered to be an abundant resource of bioactive natural products possessing diverse pharmacological properties and unique chemical structures, that is powerfully proved by the existence of structurally novel vibsane-type diterpenoids which only occur in Viburnum species, newly discovered lignan constituents with unusual side chains and other noteworthy natural components. This review describes 185 new and 228 known secondary metabolites from Viburnum genus between 2008 and 2020, including their chemical structures, sources and bioactivities, and highlights the corresponding structure-activity relationships.

Abstract
Eleven new iridoids, brachybones A-K (1-11), were isolated from the twigs of Viburnum brachybotryum. Their structures including absolute configurations were determined by spectroscopic data analysis and from the electronic circular dichroism (ECD) spectra. All of the compounds 1-11 possess one or two acetoxysenecioate substituents. Furthermore, compounds 5-7 and 11 feature a Cl atom in the molecule, while compounds 9-11 exhibit a cagelike rigid skeleton through an unusual oxo bridge from C-3 to C-8 or C-10. The isolates were evaluated for cytotoxic activity against the HCT-116, A549, and Hela cell lines, and the results showed compounds 10 and 11 to be active against HCT-116 cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viburnum taitoense Hayata has been used as folk medicine by the minority people in Southwestern China for a long history, especially in Guangxi Zhuang Autonomous Region. The minority in Guangxi including Zhuang, Miao and Yao people use the ethanol extract of V. taitoense Hayata to treat the fracture, kill the pain of rheumatism because of its definite therapeutic effects. AIM OF THE STUDY So far, the scientific investigation of V. taitoense Hayata is done very little. Here, we first prepared the ethyl acetate extract of V. taitoense (EEVt), secondly measured the contents of phenols, flavonoids, and terpenoids in EEVt, and thirdly, the anti-inflammatory and analgesic activities of EEVt were investigated by invitro model of RAW 264.7 cells and invivo models of inflammation and pain in rats and mice. MATERIALS AND METHODS The contents of phenols, flavonoids, and terpenoids in EEVt were determined by UV spectrophotometry, respectively. The anti-inflammatory effect of EEVt (5, 25, 50, 100, and 200 μg/mL) in vitro was tested by determining its inhibitory effect on the nitric oxide production of RAW264.7 cells activated by lipopolysaccharide (LPS). The anti-inflammatory and analgesic effects of EEVt in vivo were investigated in the following experimental rats and mice models: carrageenan-induced paw edema, corton-oil-induced ear edema, acetic acid writhing test, and formalin pain test. RESULTS The contents of total phenolic, total flavonoids, and total triterpenoids in V. taitoense were measured to be 3.46 ± 0.04%, 2.38 ± 0.04%, and 14.96 ± 0.17%, respectively. In vitro test showed that EEVt at different tested dosages (5, 25, 50, 100, and 200 μg/mL) had no significant toxicity to RAW264.7 macrophages. At dosages of 37.5 and 75 μg/mL of EEVt significant inhibitory (p < 0.001) on the productions of nitric oxide (NO). High dosage (200 μg/mL) of EEVt displayed highly significant inhibitory (p < 0.001) on the productions of proinflammatory cytokines IL-6, IL-1β, and TNF-α from the LPS-induced RAW264.7 macrophages. EEVt showed obvious anti-inflammatory activity at different time points after carrageenan injection (p < 0.05) in vivo test, and its anti-inflammatory activity reached the strongest 4 h. Similarly, through the ear swelling test, EEVt (200 mg/kg) showed significant (p < 0.05) anti-inflammatory activity. Besides, formalin and acetic acid writhing experiments also showed that EEVt has significant (p < 0.05) analgesic activity. CONCLUSION EEVt was confirmed to be definite anti-inflammatory and analgesic effects, and the phytochemicals of EEVt was disclosed to be rich in triterpenoids, which was worthy to be further investigated.

Abstract
The natural product colletoic acid (CA) is a selective inhibitor of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which primarily converts cortisone to the active glucocorticoid (GC) cortisol. Here, CA's mode of action and its potential as a chemical tool to study intracellular GC signaling in adipogenesis are disclosed. 11β-HSD1 biochemical studies of CA indicated that its functional groups at C-1, C-4, and C-9 were important for enzymatic activity; an X-ray crystal structure of 11β-HSD1 bound to CA at 2.6 Å resolution revealed the nature of those interactions, namely, a close-fitting and favorable interactions between the constrained CA spirocycle and the catalytic triad of 11β-HSD1. Structure-activity relationship studies culminated in the development of a superior CA analogue with improved target engagement. Furthermore, we demonstrate that CA selectively inhibits preadipocyte differentiation through 11β-HSD1 inhibition, suppressing other relevant key drivers of adipogenesis (i.e., PPARγ, PGC-1α), presumably by negatively modulating the glucocorticoid signaling pathway. The combined findings provide an in-depth evaluation of the mode of action of CA and its potential as a tool compound to study adipose tissue and its implications in metabolic syndrome.

Abstract
Inspired by natural 11β-HSD1 inhibitors hupehenols A - E, a ring-focused strategy was applied for the synthesis of 35 structurally diverse dammarane-type derivatives. These derivatives were effectively prepared from protopanaxadiol based on the modification of rings A and D. Among these compounds, ten were identified as selective 11β-HSD1 inhibitors (IC50 range: 101-1047 nM, SI range: 8-169) which exhibited inhibitory activities against human or mouse 11β-HSD1. Otherwise, we found 23a could selectively inhibit both human and mouse 11β-HSD1 with IC50 value of 994 and 213 nM (SI > 10 and > 47), respectively. Additionally, the molecular modelling results of 23a docking into the human and mouse 11β-HSD1 were in good agreement with the results from the enzyme inhibitory experiment. Moreover, valuable structural-activity relationship (SAR) information of dammarane-type 11β-HSD1 inhibitor was summarized.

Abstract
Four new dammarane-type triterpenoids (1-4) and twelve known compounds (5-16) were isolated from the leaves of Viburnum sambucinum Reinw. ex Blume. Their structures were determined by spectral data analysis, including MS and 2D NMR. Cytotoxic activity evaluation in vitro against four cancer cell lines (KB, LU-1, HepG2 and MCF7) suggested that the octanor-dammarane derivatives were the main cytotoxic components of the leaves of V. sambucinum.
