Aloperine is an isolated alkaloid in sophora plants such as Sophora alopecuroides L, and exhibits anti-inflammatory, antibacterial, antiviral, and anti-tumor properties.

Compared with other alkaloids including sophoridine, sophocarpine, matrine, oxymatrine and cytisine, Aloperine treatment exerts the most potent cytotoxic activity against human cancer cell lines of differing tissue origins, including leukaemia cell lines HL-60, U937 and K562, oesophageal cancer EC109 cells, lung cancer A549 cells and the hepatocellular carcinoma HepG2 cell line with IC50 of 0.04 mM, 0.27 mM, 0.36 mM, 1.11 mM, 1.18 mM, and 1.36 mM, respectively. The strongest cytotoxic effect of Aloperine on HL-60 cells is observed at 72 hours with the inhibition rate of 94.1%.In contrast to the effect on leukaemia cells, up to 1 mM of Aloperine does not significantly reduce the viability of normal PBMNCs at 72 hours. Aloperine treatment at 20 μM for 48 hours significanlty induces apoptosis and autophagy in HL-60 cells in a dose-dependent manner.
Topical application of 1% Aloperine suppresses 2, 4-dinitrofluorobenzene (DNFB)-induced increase in ear thickness and ear erythema in BALB/c mice, and significantly decreases the up-regulated mRNA and protein levels of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and interleukin-6 (IL-6) induced by DNFB in ear biopsy homogenates. Topical application of Aloperine reduces the DNFB-induced dermatitis (dermatitis index and ear thickness) in NC/Nga mice at day 13 and day 14 in a dose-dependent manner. Aloperine treatment reduces DNFB-induced lymphocytes infiltration and eosinophils infiltration in a dose-dependent manner. Aloperine treatment also reduces the DNFB-induced infiltration of mast cells in a dose-dependent manner. Aloperine reduces the plasma level of IgE in a dose-dependent manner. Aloperine markedly reduces DNFB-induced increase in IL-4, IL-13 and IFN-γ productions, while it increases the IL-10 level in a dose-dependent manner. Aloperine treatment significantly reduces the cytokine levels of TNF-α, IL-1β and IL-6 in ear biopsies homegenates of NC/Nga mice in a dose-dependent manner.
