Abstract
Ridaifens (RIDs), a novel series of tamoxifen derivatives, exhibit a potent growth-inhibitory effect against numerous tumor cells regardless of the expression of estrogen receptors, and are thus promising candidates as novel anti-tumor drugs. RID-B is a first generation RIDs, and inhibits the proliferation of several tumor cell lines. However, the potentially growth inhibitory effect of RID-B against hepatoma cells, and the detailed mechanism underlying RID-B-mediated tumor cell death remain to be elucidated. The purpose of the current study was to evaluate the anti-proliferative effect of RID-B against hepatoma cells. The anti-proliferative effect of RID-B against human hepatoma Huh-7 cells was investigated by cell proliferation assay using WST-1 reagent, and caspase-3 activity was evaluated by using specific fluorescent substrate. In addition, DNA fragmentation in Huh-7 cells induced by RID-B was estimated by terminal deoxynucleotidyl transferase dUTP nick-end labelling assay, and binding of RID-B to double-stranded DNA was confirmed by mass spectrometry. RID-B (0.5, 1 and 2 µM) inhibited the growth of Huh-7 cells, seemingly dose-dependently, but did not inhibit the growth of normal primary rat hepatocytes in the same concentration range. Furthermore, the caspase-3 activity of Huh-7 cells was increased by RID-B (0.5 and 5 µM), and the anti-proliferative effect of RID-B (1 µM) on Huh-7 cells was partially suppressed by the addition of the caspase inhibitor, Z-VAD-FMK. Additionally, RID-B (10 µM) directly bound to double-stranded DNA, and the addition of DNA suppressed RID-B-mediated cell growth inhibition and DNA fragmentation in Huh-7 cells. From these data, it may be concluded that RID-B inhibited cell growth and induced apoptosis via activating caspase-3 and binding to DNA directly, leading to DNA fragmentation in hepatoma cells.

Abstract
Both ERα and VEGFR-2 are important targets for cancer therapies. Here a series of 2, 4-disubstituted pyrimidine derivatives were designed, synthesized and evaluated as dual ERα/VEGFR-2 ligands. Most of the derivatives exhibited potent activities in both enzymatic and cellular assays. Structure-activity relationship studies showed that a hydrogen-bonding interaction in the head section is important factors for the enhancement of ERα-binding affinity. The most potent compound II-9OH, an analog of 2-(4-hydroxylphenyl)pyrimidine, was 19-fold more efficacious than tamoxifen in MCF-7 cancer cells and exhibited the best ERα binding affinity (IC50 = 1.64 μM) as well as excellent VEGFR-2 inhibition (IC50 = 0.085 μM). Furthermore, this dual targeted compound II-9OH exerted significantly antiestrogenic property via suppressing the expression of progesterone receptor (PgR) mRNA in MCF-7 cells and also showed obvious in vivo angiogenesis inhibitory effects in CAM assay. An induction of apoptosis and a decrease in cell migration, accompanied by transduction inhibition of Raf-1/MAPK/ERK pathway, were observed in MCF-7 cells after treatment with II-9OH, suggesting that II-9OH is a promising candidate for the development of multifunctional agents targeting ERα and VEGFR-2 in the therapy of some breast cancers.

Int J Oncol 2018; 52:1339-1349. [PMID: 29436614 DOI: 10.3892/ijo.2018.4271] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Accepted: 02/06/2018] [Indexed: 11/05/2022] Open
Abstract
Arctigenin, a member of the Asteraceae family, is a biologically active lignan that is consumed worldwide due to its several health benefits. However, its use may pose a problem for patients with estrogen receptor (ER)α-positive breast cancer, since studies have shown that arctigenin is a phytoestrogen that exerts a proliferative effect by binding to the ER. Thus, in this study, we examined the effect of arctigenin on ERα-positive MCF-7 human breast cancer cells to determine whether the consumption of arctigenin is safe for patients with breast cancer. First, we found that arctigenin inhibited the viability of the MCF-7 cells, and colony formation assay confirmed that this effect was cytotoxic rather than cytostatic. The cytotoxic effects were not mediated by cell cycle arrest, apoptosis, or necroptosis, despite DNA damage, as indicated by poly(ADP-ribose) polymerase (PARP) cleavage and phosphorylated H2A.X. An increase in lipidated LC3, a marker of autophagosome formation, was observed, indicating that autophagy was induced by arctigenin, which was found to be triggered by the inhibition of the mechanistic target of rapamycin (mTOR) pathway. We then examined the effects of arctigenin on ERα expression and determined whether it affects the sensitivity of the cells to tamoxifen, as tamoxifen is commonly used against hormone-responsive cancers and is known to act via the ERα. We found that treatment with arctigenin effectively downregulated ERα expression, which was found to be a consequence of the inhibition of the mTOR pathway. However, treatment with arctigenin in combination with tamoxifen did not affect the sensitivity of the cells to tamoxifen, but instead, exerted a synergistic effect. On the whole, our data indicate that the phytoestrogen, arctigenin, mainly targeted the mTOR pathway in ERα-positive MCF-7 human breast cancer cells, leading to autophagy-induced cell death and the downregulation of ERα expression. Furthermore, the synergistic effects between arctigenin and tamoxifen suggest that the consumption of arctigenin is not only safe for patients with hormone-sensitive cancers, but may also be an effective co-treatment.
