Abstract
Phytochemical investigation of the fruit and flowers of Passiflora foetida led to the isolation of 14 compounds, of which five are previously undescribed fatty acid lactones. Four 2-pyrones, passifetilactones A-D (1-4), and one furanone, passifetilactone E (5), were identified by analysis of spectroscopic and spectrometric data. The previously undescribed lactones were tested for cytotoxic activities against the cancer cell lines HeLa, A549, PC-3, KKU-055, and KKU-213A and two normal cell lines, Vero and MMNK-1. Passifetilactones B (2) and C (3) displayed good to mild cytotoxic activity, at IC50 3.7-25.9 μM and 12.2-19.8 μM, respectively, against six cell lines, but were weakly active against the MMNK-1 cell line. Passifetilactones B and C (2 and 3) showed cell apoptosis induction on the KKU-055 cell line in a flow cytometry experiment. Passifetilactone D (4) is an isolation artifact produced by purification over silica gel, but we demonstrated that it can also be slowly formed within the crude EtOAc extract. This is the first investigation of the flowers and the fruit of this plant.

Acrotrione B, a Prenylated and Highly Oxidized Xanthenoid with Antibacterial and Anti-proliferative Activities from the Roots of Acronychia pedunculata. PLANTA MEDICA 2023; 89:416-422.

Abstract
A new prenylated xanthenoid with a highly oxidized core, acrotrione B (1: ), together with six previously reported acetophenones (2: - 7: ), were isolated from the roots of Acronychia pedunculata. The structures of the isolated compounds were elucidated by thorough analysis of their 1D and 2D NMR spectroscopic data. The relative and absolute configurations of acrotrione B were determined by electronic circular dichroism (ECD) calculations. Acrotrione B is an unusual, oxidized xanthenoid with a cyclohexadienone core that has not been previously reported. It thus represents a new skeletal type within the xanthenoid class. Acrotrione B (1: ) exhibited anti-proliferative activity against Hela (IC50 = 16.0 µM) and A549 (IC50 = 16.3 µM) cell lines. 5'-Prenylacrovestone (4: ) and acrovestone (5: ) were even more potent with IC50 values of 5.1 µM and 0.77 µM, respectively, against Hela cells and 11.8 µM and 1.13 µM, respectively, against A549 cells. Moreover, acrotrione B (1: ) displayed moderate antibacterial activities against Staphylococcus aureus, Bacillus cereus, and Bacillus subtilis, with MIC values in the range of 16 - 64 µg/mL. Finally, acropyrone (6: ) showed a significant suppression of lipopolysaccharide (LPS) induced NO production in murine macrophage J774.A1 cells (IC50 = 8.9 µM).

Abstract
Phytochemical investigation of the flowers of Anomianthus dulcis led to the isolation of eleven known compounds. The isolated compounds were identified by analysis of physical and spectroscopic (IR, 1 D and 2 D NMR) data. We report five flavonoids (1-4 and 10), two chalcone-sesquiterpenoids (5 and 6), one indole alkaloid (7), one triterpenoid (8), and a mixture of two phenolic compounds (9 and 11). Remarkably, it is the second isolation of sumadain A (5) and sumadain B (6) from a natural source. Compounds 5 and 6 were evaluated against several cancer cell lines, as the previous report lacked biological activity studies. Compound 6 showed strong cytotoxicity against Hela, HT-29, HCT-116, and A549 cell lines, with IC50 values in the range of 5.43-14.64 µg/mL.
