Main Challenge

The main challenge of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistant after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Natural compounds deriving from traditional Chinese medicine are known to have low toxicity and genuine promising effects in reversing multidrug resistance, either induced by orthodox chemotherapeutic or targeted therapy drugs. Numerous mechanisms including suppression of drug efflux, detoxifying systems, DNA repair systems, and anti-apoptosis pathways were responsible for such process. A range of natural compounds functioned on the suppression of apoptosis are widely reported, which include flavonoids, terpenoids, alkaloids, quinones, xanthones, saponins and polysaccharides. Here, this review summarized comprehensive data from in vitro and in vivo studies to elucidate the functional roles of natural compounds in reversing multidrug resistance during cancer therapy.

In the present review, the literature data on the chemical constituents and biological investigations of the genus Pedicularis are summarized. Some species of Pedicularis have been widely applied in traditional Chinese medicine. A wide range of chemical components including iridoid glycosides, phenylpropanoid glycosides (PhGs), lignans glycosides, flavonoids, alkaloids and other compounds have been isolated and identified from the genus Pedicularis. In vitro and in vivo studies indicated some monomer compounds and extracts from the genus Pedicularis have been found to possess antitumor, hepatoprotective, anti-oxidative, antihaemolysis, antibacterial activity, fatigue relief of skeletal muscle, nootropic effect and other activities.

Antitumor Properties

To discover and develop novel natural compounds, active ingredients, single herbs and combination formulas or prescriptions in traditional Chinese medicine (TCM) with therapeutic selectivity that can preferentially kill cancer cells and inhibit the amplification of cancer without significant toxicity is an important area in cancer therapy. A lot of valuable TCMs were applied as alternative or complementary medicines in the United States and Europe. But these TCMs, as one of the main natural resources, were widely used to research and develop new drugs in Asia. In TCMs, some specific herbs, animals, minerals and combination formulas were recorded and exploited due to their active ingredients and specific natural compounds with antitumor activities. The article focused on the antitumor properties of natural compounds and combination formulas or prescriptions in TCMs, described its influence on tumor progression, angiogenesis, metastasis, and revealed its mechanisms of antitumor and inhibitory action. Among the nature compounds, triptolide, berberine, matrine, oxymatrine, kurarinone and deoxypodophyllotoxin (DPT) with specific molecular structures have been separated, purified, and evaluated their antitumor properties in vitro and in vivo. Cancer is a multifactorial and multistep disease, so the treatment effect of combination formulas and prescriptions in TCMs involving multi-targets and multi-signal pathways on tumor may be superior than that of agents targeting a single molecular target alone. Shi Quan Da Bu Tang and Yanshu injection, as well known combination formulas and prescriptions in TCMs, have shown an excellent therapeutic effect on cancer.

Coriolus versicolor is an herb widely used for cancer treatment in traditional Chinese medicine. Its active ingredients, polysaccharopeptides (PSP), have been used for adjuvant therapies in cancer treatment. This study conjugates Coriolus versicolor PSP with poly(ethylenimine) (PEI) to generate a PSP-PEI copolymer for gene transfer. After PEI conjugation, both the pH buffering capacity and DNA compaction ability of PSP are significantly increased. Compared with that of PSP, the transfection efficiency of PSP-PEI is 10 to 20-fold higher in vitro. This is a proof-of-concept study reporting the direct use of bioactive phytochemicals from traditional Chinese medicine for gene vector development. The promising performance of PSP-PEI raises the possibility that bioactive herbal ingredients can be further developed as a multi-therapeutic gene carrier for tackling cancers.

Endothelial Growth Factor

Background: Age-related macular degeneration (AMD) is a progressive and irreversible eye disease. The anti-vascular endothelial growth factor (VEGF) therapy has revolutionized the treatment of neovascular AMD. However, the expense for such treatment is quite high. Methods: We used a traditional Chinese medicine ZQMT as an alternative therapeutic regimen for AMD. We employed two in vivo animal models mimicking dry and wet AMD respectively to assess the therapeutic efficacy of ZQMT on treating AMD-related retinopathy. AMD-related retinopathy in Crb1rd8 mice was evaluated from week 1 to 8 by fundus photography. Laser-induced choroidal neovascularization (CNV) was evaluated by fluorescein angiography and histopathology. Results: ZQMT increased CX3CR1 expression in murine CD4+ T cells either cultured in vitro or directly isolated from animals treated with ZQMT. We also performed both in vitro and in vivo studies to confirm that ZQMT has no apparent toxic effects. ZQMT alleviated AMD-related retinopathy in both Crb1rd8 and CNV models. Depletion of CCL2 and CX3CR1 in Crb1rd8 mice abolished the efficacy of ZQMT, suggesting that CCL2 and/or CX3CR1 may underlie the mechanisms of ZQMT in treating AMD-related retinopathy in mice. Conclusion: In summary, our study supports the protective roles of a traditional Chinese medicine ZQMT in AMD.

In traditional Chinese medicine, Ranunculus japonicus has been used to treat various diseases, including malaria, and the young stem of R. japonicus is consumed as a food in the Republic of Korea. However, experimental evidence of the antimalarial effect of R. japonicus has not been evaluated. Therefore, the antimalarial activity of the extract of the young stem of R. japonicus was evaluated in vitro using both chloroquine-sensitive (3D7) and chloroquine-resistant (Dd2) strains; in vivo activity was evaluated in Plasmodium berghei-infected mice via oral administration followed by a four-day suppressive test focused on biochemical and hematological parameters. Exposure to extracts of R. japonicus resulted in significant inhibition of both chloroquine-sensitive (3D7) and resistant (Dd2) strains of P. falciparum, with IC50 values of 6.29 ± 2.78 and 5.36 ± 4.93 μg/mL, respectively. Administration of R. japonicus also resulted in potent antimalarial activity against P. berghei in infected mice with no associated toxicity; treatment also resulted in improved hepatic, renal, and hematologic parameters. These results demonstrate the antimalarial effects of R. japonicus both in vitro and in vivo with no apparent toxicity.

Malignant T Cells

Herbs have successfully been used in traditional Chinese medicine for centuries. However, their curative mechanisms remain largely unknown. In this study, we show that Wogonin, derived from the traditional Chinese medicine Huang-Qin (Scutellaria baicalensis Georgi), induces apoptosis in malignant T cells in vitro and suppresses growth of human T-cell leukemia xenografts in vivo. Importantly, Wogonin shows almost no toxicity on T lymphocytes from healthy donors. Wogonin induces prolonged activation of PLCγ1 via H2O2 signaling in malignant T cells, which leads to sustained elevation of cytosolic Ca2+ in malignant but not normal T cells. Subsequently, a Ca2+ overload leads to disruption of the mitochondrial membrane. The selective effect of Wogonin is due to its differential regulation of the redox status of malignant versus normal T cells. In addition, we show that the L-type voltage-dependent Ca2+ channels are involved in the intracellular Ca2+ mobilization in T cells. Furthermore, we show that malignant T cells possess elevated amounts of voltage-dependent Ca2+ channels compared with normal T cells, which further enhance the cytotoxicity of Wogonin for malignant T cells. Taken together, our data show a therapeutic potential of Wogonin for the treatment of hematologic malignancies.
