Abstract
Four new dimeric styrenes, 1-4, were isolated from an EtOAc crude extract of the seeds of Atalantia monophylla. The biosynthetic pathway of 1 is proposed to involve a [2 + 2] cycloaddition, while 2-4 may be generated via a polar mechanism with a carbocation as the key intermediate. The structures of 1-4 were defined from spectroscopic analysis; experimental and calculated ECD spectra were used to characterize their absolute configurations. When tested against two different cancer cell lines, 1-4 were not determined to be cytotoxic (IC50 > 10 μM).

Abstract
Three new limonoids, limonophyllines A-C (1, 4 and 5), along with two known limonoids (2 and 3) and 11 acridone alkaloids (6-16) were isolated from the stems of Atalantia monophylla. All isolates were evaluated against cholangiocarcinoma, KKU-M156, and HepG2 cancer cell lines. Compounds 12, 14 and 16 displayed cytotoxicity against KKU-M156 cell line with IC50 ranging from 3.39 to 4.1 μg/mL while cytotoxicity against HepG2 cell line with IC50 ranging from 1.43 to 8.4 μg/mL. The structures of all isolated compounds were established by spectroscopic methods including 1D and 2D NMR, IR and mass spectrometry.
