Article Abstract
A new polyoxygenated cyclohexene, (-)-3-O-debenzoylzeylenone (1), and a new megastigmane glycoside, grandionoside A (2), were isolated from the aerial parts of Uvaria grandiflora collected in Vietnam, together with ten known compounds including polyoxygenated cyclohexenes (3-6), a triterpenoid (7), an alkaloid (8), a long chain alcohol (9), hexenyl glycopyranoside (10), and saponins (11-12). Their chemical structures were elucidated by a combination of extensive NMR spectroscopy with X-ray crystallographic analysis for 1, and chemical conversion for 2. Compound 1 exhibited significant cytotoxicity against the LU-1 and SK-Mel-2 cell lines with IC50 values of 4.68 and 3.63 μM, respectively. Remarkably, the cytotoxicity of 12 against the LU-1, KB, Hep-G2, MKN-7, and SW-480 cell lines was comparable to that of ellipticine, the positive control, with IC50 values ranging from 1.24 to 1.60 μM.

Nine previously undescribed polyoxygenated cyclohexenes uvacalols L-T (1-9), together with five known analogues (10-14) were obtained from the stems of Uvaria calamistrata. Their structures were established through spectroscopic data analysis, circular dichroism calculations and single-crystal X-ray diffraction. Uvacalols L-N (1-3) are chlorinated analogues.

Twelve polyoxygenated cyclohex(a/e)ne diterpene esters, named albiflorenes A-L (1-12), were isolated from the whole plants of Kaempferia albiflora, known as "Prao Mang Mum." Their structures and relative stereochemistry were determined by extensive spectroscopic analysis. Furthermore, the comparison of experimental electronic circular dichroism (ECD) curves with the curves predicted by TDDFT was used to determine the absolute configurations.

Due to its highly aggressiveness and malignancy, glioblastoma (GBM) urgently requires a safe and effective treatment strategy. Zeylenone, a natural polyoxygenated cyclohexenes compound isolated from , has exhibited potential biological activities in various human diseases, including tumors. We designed and synthesized a series of (+)-Zeylenone analogues and evaluated their anti-GBM roles through structural-activity analysis.

This article reviews the geographical distribution, ethnomedicinal applications, and phytochemistry of the genus Baill, tribe Uvariae of the family Annonaceae. The reviewed works of literature were collected from various electronic databases including Google Scholar, PubMed, Science Direct, The International Plant Names Index (IPNI), and Research Gate. During this review, ninety-eight species of the genus were found to be widely distributed in tropical Africa.
