9c(i472) is an inhibitor of 15-lipoxygenase-1 (15-LO-1; IC50 = 0.19 μM).1 It decreases LPS- and IFN-γ-induced NF- B activity in RAW-Blue cells when used at concentrations of 0.2, 1, and 5 μM. 9c(i472) reduces LPS- and IFN-γ-induced increases in Nos2 expression and lipid peroxidation in RAW 264.7 cells when used at a concentration of 5 μM.
Caffeoylcalleryanin demonstrated potent inhibitory activity against 15-lipoxygenase (15-LOX), with an IC50 value of 1.59 μM. Furthermore, ethanol extract from A. pulchra leaves (EEAPL) was found to contain compounds exhibiting antiviral properties, particularly effective against Dengue virus type 2 (DENV-2). Among these compounds, Caffeoylcalleryanin emerged as the most potent anti-DENV-2 agent, achieving a selectivity index (SI) of 20.0.
TopoisomeraseI II inhibitor 6(compound 3i)作为topoisomerase I 和 II 的抑制剂显示出优异的效能,其IC50值分别为4.77 µM和 15 µM。此外,该化合物在人类黑色素瘤LOX IMVI癌细胞系中展示了显著的抗增殖效果,IC50值达到了26.7 µM和25.4 µM。
